    Meanwhile China is building it's own giant telescopes: https://www.science.org/content/article/china-quietly-prepar...

    And will soon launch their own version of Hubble: https://en.wikipedia.org/wiki/Xuntian

    Deeply embarrassing as a US citizen.

      > Deeply embarrassing as a US citizen.

      agreed. America's attitude towards china has been absurd. instead of seeing it as an opportunity for us to step up, we deflect responsibility as if america was forced to offshore its manufacturing and venerate idiots over scientists.

        I think a big part of it is that the admission that offshoring was a bad idea that has created a threat to American hegemony would require acknowledgement that neoliberalism has been an abject failure and a ruse by the upper class to suck up capital and political power from the middle class.

        That sort of discussion and the consequences from having it just isn't on the menu.

        There isn't going to be a massive wealth redistribution in the other direction to offset the redistribution that has taken place over the last 40 years. There isn't going to be taxation reforms to prevent this from occuring again. There isn't going to be a focus on white collar crimes from the Justice department.

        Things are just going to slowly get worse and worse in America.

          Well, a peaceful one anyway. As much as it sickens me. We don't have to go back more than 200 years to see what happens when the wealth gap gets too large.

          Is this comment a bit reductionist? Sure. Doesn't mean its more wrong than right.

            What are you talking about? The current president was elected on the platform that offshoring was a bad idea that has created a threat to American hegemony. Free trade is politically dead now.

            I wish we could operate on the principle of data sharing in science. What a waste of resources to needlessly replicate and compete. Also, great, somebody else is doing it so we don’t have to! Less work for us.

              This is already how astronomy, and specifically cosmology, research works in the US (and most other places). Data is made public within a short period of obtaining it on a schedule (usually less than a couple years) that is set before data is taken.

              It is far from clear that the Chinese government supports this type of open data sharing.

              "Deeply embarrassing as a US citizen."

              Agreed. The US has squandered so much money over the decades that they're now over $300k/taxpayer in debt, with interest to that that being the fourth largest cost, and two of the top three being insufficiently funded programs that simply steal from the grandchildren.

              It would be even more embarrassing if we didn't cut back on non-essential spending.

                Being at the forefront of science is not ~non-essential~.

                It is literally one of the most important things to make a nation great.

                  This retroactive stuff is pointless. The US can't do anything right, but if it stops doing anything it's doing it's a catastrophe.

                  Perhaps this pain would be worth it if we also cut back on non-essential tax-cuts for the rich.

                  Instead, we're cutting cheap scraps like this from the budget while the fattest fucks at the table get to gorge themselves for another two years.

                    Boy are you going to feel bad as you watch what happens to the debt over the next few years.

                    • apical_dendrite 1 day ago
                      Yeah, let's cut back on the relatively small investments in science that actually grow the economy, particularly at a moment in time when our geopolitical competitors are making enormous investments, and when leadership and talent in science is more important than ever.

                      Just walk around the Boston area and look at how much of the economy is driven by federal research funding attracting global talent to universities, which then generates ideas and the next generation of talent, which feeds the biotech companies, which grow the economy.

                      Letting all of that happen in China instead of the US just to make a tiny dent in the deficit (and to punish progressive institutions and prevent cultural change from immigration) is unbelievably fucking stupid.

                        Trump just added 4 trillion more in debt funding tax cuts for billionaire. The amount of money science research gets in the US is pennies compared to that. Investments in science always returns on investment in the form of technology. The internet was a research project mind you.

                        Yeah but does China have tax cuts for the rich?

                        Because let's be real here all the patriotism is just a facade the rich want to keep the money for themselves. Singing the national anthem on the fourth of July is cheap.

                        • elcritch 1 day ago
                          Yes, especially if you’re part of the CCP [1]. Well if they’re taxed at all. Can’t be taxed if you hide your wealth.

                          At least the wealth of the richest people in the US is made by people producing value and services. Bezos is rich because people like myself find Amazon and AWS to be quite good.

                          IMHO, the biggest wealth problem in the US is the rise of upper-middle class “elites” and management class. The one driving “mergers and acquisitions” to reduce competition between grocery stores or using rent control software to eke up rent costs.

                            This, and many other things in the area of science, is an embarrassment.

                            However, I feel that what is argued about, by all sides, misses the point.

                            The US spends 2X what China does on civilian space programs, and 4X what Europe spends. We spend 2X as much on health care, 1.5X as much on education, and 2X as much on science research.

                            Our systems are inefficient and corrupt, and that is what needs to be addressed.

                            Arguing for or against how much money we need to spend or to cut is just the modern day circus that distracts everyone from the real problems and provides everyone on both sides with feel good excuses.

                              Citation needed. Even Musk's DOGE trolls found no evidence of significant corruption/inefficiency.

                                The first few areas are easy,since budgets are known and there are actual comparative measurements that have been done.

                                Health. We spend $5T a year on our "health", which is 2X the per capita amounts spent by western European countries, yet we have poorer outcomes. We have poorer outcomes not just among lower income classes, but also poorer outcomes when comparing upper class incomes between the US/Europe

                                Education. We spend 1.5X per capita compared to western European nations, and we have poorer outcomes

                                If we would simply match the budgets for these two areas with European budgets, and even accept the fact that they would have better systems in place, we would save $3T a year. This is a fairly direct measure of how much more efficient Europe is with their resources. They are either that much better/smarter than we are, or we have a corrupt system, or a combination of the two.

                                Public construction costs. It costs 50% to 200% or even more to build public projects in the US than in Europe. That is, if we can even complete our projects. One of many reports and analysis: https://www.constructiondive.com/news/us-rail-projects-take-...

                                Other areas are difficult to have direct comparisons, and it is difficult to compare results. The US solution to everything is to pour money into it. And it seems that any cut, any type of cut at all, portends doom.

                                Military. We spend $1T a year. We have something like 1200 military bases, over half are international. We have massive cost and time overruns all the time. Yes, we may have the best military in the world, but it certainly feels like the taxpayers are being taken advantage of. You may feel differently. I do not think we need 1200 based. I do think that the military industrial complex profits way beyond what is reasonable.

                                Science research. We spend about $1T in R&D, almost triple of Europe. We pay our researchers 2X-3X what researchers make in Europe. Yet it seems that any type of cut to science budgets is met with the proclamation that we will lose all of our researchers to Europe. Our major research centers need a 70% incidental budget on top of their grants otherwise they will go out of business. CEO's of major non profit medical research centers need to make millions and millions of dollars per year. There is something wrong here.

                                Space. We spend 2X what China spends, and 4X what Europe spends. One example is the costs of space telescopes: China spends 9 figures, Europe spends 10 figures, and we spend 11 figures. NASA's SLS rocket is a case study in how to literally brun up billions and billions of taxpayers money. We can, and need to do better.

                                Corruption is not always the simple graft of the CEO and board. Corruption also comes in the form of a system where too many people make too much profit to want to make the system better.

                                On the other hand, the US is close to bankruptcy. And that's not all the current admin's fault.

                                And their cuts are trying to avoid that, although they have thrown out many babies with the bath water. It's hard to blame them for trying to avoid default, which would be far worse than anything.

                                The program apparently cost $900 million which is not a trivial cost.

They had moveable type before Gutenberg, but had a culture, government, and language that were all factors against its propagation. They had a navy second to none, but found the rest of the world not interesting (Confucian Conservatism is one theory) and dismantled it, nearly a century before Magellan's voyages. If anything, their knowledge leaked to the rest of the world as opposed to them leading it.

                                                                    Today, China is playing Go with the world as their board. We have to start counting liberties on our groups; the late game is now.

                                                                  It really hurts to see this happening. CMB-S4, stands for stage 4, is a huge collaborative effort that units many CMB scientists and experiments, in a sense that stage 1 to 3 experiments are “converging” towards this.

                                                                  To put that in context, CMB-S4 being a DOE project has many side effects to other CMB experiments in a lot of ways. For example, a few years ago the LiteBIRD mission led by JAXA from Japan has been gaining momentum, and many international CMB scientists got involved. European scientists got funded by ESA, and US scientists were expecting NASA to fund them too. In the end they denied the proposal (despite generally positive impressions when discussing with various people there), partly because they think the satellite based CMB experiment LiteBIRD has significant overlap with the goals of the ground based CMB experiment CMB-S4, deeming it unnecessary to support LiteBIRD.

                                                                  And then CMB scientists used to get generous access to NERSC, a top 10 HPC system in the world. But as CMB-S4 becomes a DOE project, NERSC being DOE funded also, it becomes a bit of conflict there, in the sense that they feel they need to prioritize access for CMB-S4 to guarantee its success. There are many other factors in play but in the end it becomes much more difficult to even get access to the system, not to mention having any sizable allocation.

                                                                  All these might not be so bad as CMB-S4 is supposed to be our endgame. It would benefits the CMB community as a whole so much. But now? It’s game over.

                                                                  It also hurts particle physics progress as well. Long story short, the CMB B-mode holds a promising sensitivity to inflationary models, that its discovery may finally makes inflation falsifiable. At the very least, it involves an energy scale so high that no experiments on Earth can reach, and therefore is a good complement, to high energy physics experiments such as LHC.

                                                                  There is a reason it is deemed so important in both the decadal survey and the Particle Physics Project Prioritization Panel.

                                                                  Project like this has under heavy scrutiny from both the scientific community and the funding parties around feasibility, risks, costs, etc. It wasn’t a a light decision to have had happened in the beginning. Why would the end come so abruptly without explanation?

                                                                  • ethagknight 22 hours ago

Something about the faint, far off “redshift” background radiation from the beginning of time was actually coming from a much closet newer source , not what the theories held? I’ll repost paper if I can find it.

                                                                      A $1B cut for ΛCDM seems pragmatic as long as we focus on the economy. The cosmic background will still be waiting for us in four to ten years.

                                                                      Unfortunately, it feels like the budget cuts being made are incredibly partisan and not actually helping pay down the debt spiral. Especially when the deficit is increasing.

                                                                      Everything needs to be cut back, not just things one party doesn't care for.

                                                                        The rate of increase of the debt increased last Friday, even as we are told we can't afford things we could afford 10 years ago.

                                                                        Put simply, we were doing a better job of managing our debts until last Friday when we decided that the national debt doesn't matter.

                                                                        • Larrikin 2 days ago

The Trump bill just makes recession more likely. The tax cuts benefit nobody but companies and the most wealthy, which Trump used to pretend he was part of but now actually is.

The amount that goes to all of this is a drop in the bucket compared to military and subsidies. hell, we spend 1/10th of the total federal science funding (~200bn) per year JUST giving free money to oil and gas companies. trying to "fix" spending this way, even if it was actually reasonable to try and do, is tantamount to trying to save to buy a house by eating two fewer avocado toasts per week.

And if we look at what's happened, I didn't see much in the way of "social services" that escaped the axe other than social security. There are, of course, cuts that could make a difference (the DEA alone is $10bil/year... and there's another $5-10bil used for DEA shit in the state dept. budget), but those are the ones that no one's willing to touch. We don't even immediately have to go after the military, though there's half a trillion per year there (or more) that could easily be cut. And guess what? Just as things are about to get desperate, world events are unfolding that will even make the most cowardly pacifist hesitate to take slices out of that.

It seems to me that almost all astronomy, particularly the sort studying very large scale phenomena like this, is essentially useless for humanity. The best it does is satisfy our curiosity about the nature of our reality, but when the subject of study is something so huge there's no chance of it ever having practical application to humanity (unlike quantum mechanics!) As for the argument that it "kills private companies" who are contracting for the government on projects like this, it seems very much like a broken windows fallacy. If the government went around breaking everybody's windows that would be great for the private companies that replace windows, but so what?

                                                                                                                    The most useful kind of astronomy is searching our solar system for dangerous rocks so that we might avert disaster. Anything beyond our solar system is just useless stargazing, everything out there is too far away for us to do anything with or about. Theories about reality which can only be validated or ruled out by looking at things so far away cannot have local relevance to us, or else whatever local phenomenon they govern which might be useful to us could also be used to test that theory.

                                                                                                                    (For the record, I think this administration are a bunch of morons.)

We're exploring for the sake of finding answers about the universe, and in the process learning 'unknown unknowns' which may pay off later. Using your example - quantum mechanics wasn't invented with computer chips in mind.

                                                                                                                      Having said that I think that there are some practical benefits coming from this research that aren't commonly discussed. For example: adaptive optics - which is heavily used in astronomy - is also used in medical imaging and national defense. Astronomers also drive a lot of detector development. Previously this was the CCD, now things are moving into new, exotic devices like MKIDs. Maybe one of these new detectors will end up in a mobile phone camera in the future, and you'll be able to take excellent photos in low-light levels. There are many more examples I'm sure, but this is just what I have off the top of my head..

                                                                                                                      The final practical AND philosophical application I can think of, is that we are about 10-20 years away from putting direct constraints on life in the universe. A big proportion of astronomers are currently working on this. I think an answer to this question will dramatically change how society views itself.

                                                                                                                      • II2II 2 days ago

A mere 100 years back it would've been impossible to conceive that these imaginary "atoms" will lead to reserves of immense energy. And yet here we are today living in a world only made possible because of what people did before.

                                                                                                                        The cosmic microwave background is not even something imaginary far away in time or space. It is radiation that surrounds us in the present. It is passing by the earth constantly, all the time. There's some research trying to use it for space navigation, but no one knew you could do that when they pointed antennas randomly in the sky. The amount of cross over some research has to a lot of other research and eventually to practical applications cannot be easily comprehended. Science builds upon science in very complex and convoluted ways with each step being that people simply tried to find more about something around them that they did not know. If you knew how to find it, then there's nothing to research in the first place, is there?

                                                                                                                        There must be so much information in cosmic microwave radiation about things we may not even know. Who knows if it could lead to uncovering information about dark matter or dark energy and who knows where that information would take human civilization. At this time, research simply indicates that you find out as much about it as you can, because it is there!

                                                                                                                          The funny thing is: this science with few direct application to human affairs is one of the oldest sciences. Those few applications, as a standard of time and use in navigation, have had a far greater impact upon the establishment of human civilization than any other scientific discover.

                                                                                                                          It would be easy to argue that those are things of the distant past and that other branches of science have a more direct impact today. That's true. Yet it is also true that our curiosity of the heavens has been a constant. While our early notions were pure nonsense, they shaped society. While our initial discoveries of its true nature had little immediate impact upon everyday life, it formed the basis of future scientific development. For example: the Copernican model of the solar system was more true to the actual form of the solar system, but it was less accurate than the more refined Ptolemaic model. Kepler figured out the ellipses bit, through the extensive observations of Tycho Brahe. Observations of planetary motion provided evidence for Newton's theory of gravitation. Ironically, observations of planetary motion also lead to the refinement of the classical model by Einstein. The understanding of gravity has been fundamental to engineering. While it is plausible that much of that would have been discovered without astronomy, the development of special and general relativity depended upon astronomy. One of the most important applications of that is GPS.

                                                                                                                          Now it would be easy to argue almost all of these discoveries have their basis in the study of the solar system, but that's not really the point. In the times of Copernicus, Kepler, and Newton, the utility of studying the motions of the planets would appear to have about as much relevance as the study of the CMB does today. They certainly would not have been able to predict what we have discovered due to the foundations they laid. The same can be said of modern astrophysics. We can claim that it may help us detect and understand the nature of gravitation waves. We can claim that it is a handy tool since "the universe" is better at building particle accelerators than we are. Yet even if we made astounding discoveries along those line, people would still ask: what use is it? We can't really provide an honest answer for that since we have yet to travel that path through time (i.e. we don't know what the future holds).

                                                                                                                          If you ever have a chance, I suggest reading a book on the history of astronomy. You will find many names that you will probably know from other branches of science, and learn of the many discoveries that have been made or facilitated through astronomical research. (That's particularly true of physics and mathematics.)

                                                                                                                              Relativity was discovered after discrepancies were noticed in observations of Mercury, right in our solar system. Not through observations of distant galaxies. And suppose Mercury was never studied, or in fact never existed; would that make GPS impossible for humanity? Of course not. Relativity is relevant to GPS because it has effects on the scale of GPS, and can therefore be discovered and studied by simply putting very accurate clocks into orbit. Had it not already been known of when GPS was created, it would have been discovered soon after.

                                                                                                                              In fact, studying very large and very distant things, other galaxies namely, has revealed discrepancies that suggest general relativity might not be the whole story. But is that relevant to GPS? Not in the slightest.

                                                                                                                              • ac794 2 days ago
                                                                                                                                I see what you're saying and agree that we probably would have noticed the discrepancies in GPS positioning pretty quickly if we had tried to make it work without knowing about general relativity (GR). But it took _Einstein_ the better part of a decade to develop GR. Even if he hadn't existed, GR still would have had to be discovered by scientists using public funding. What company would pay someone to work on this problem for 10 years without a guarantee of success?

                                                                                                                                I also don't think there is a strong correlation between studying things close-by, e.g. in our solar system, and how useful the finding will be. Our next break through in particle physics may come from studying dark matter, black holes or quasars. Maybe that will help us build even better computers? Or faster than light communication? We don't know where the treasure is buried!

                                                                                                                                • zzzeek 1 day ago

Curiosity by people who could not dream of something like GPS at the time. Your assertion that "ok, we've dobe enough curiosity and science, it's time to stop" is unnecessary and frivolous. Funding for projects like these are miniscule fractions of the budgets of large nations like the US and they also create jobs. There is no valid reason whatsoever to cancel this research except for the sole, actual reason, which is as always, "to own the Libs".

Our government is purportedly Of the people, For the people, and By the people. For this to happen the government must function as an agent for the people, not just for the tiny minority of them who own the wealth.

                                                                                                                                                              There's typically a lot of hidden value in exploring these kinds of things, and I get that, but there's not usually any particular urgency on any of them either.

                                                                                                                                                              Also, from the last paragraph of the article, it sounds like this was already on a path towards not getting funded; IMHO, it's not a major shift to get a final letter ending the project when construction was not approved a year ago.

                                                                                                                                                              • DaSHacka 1 day ago

The arguments for funding extremely time-insensitive research are usually de minimis (we spend so much more on X) or to beat the Russians/Chinese. Mass transit proponents have a similar relationship with opportunity cost. Yes, we can build California High Speed Rail, but would there be more net benefit by using the money to improve Bay Area and LA transit? You have to value these things against where the money would otherwise go.

We passed the spectacular Inflation Reduction Act - everybody's talking about it - and guess what? It didn't just tame rising prices here on Earth. No, no, we went ALL THE WAY. We ended cosmic inflation EVERYWHERE too. Incredible, right?

                                                                                                                                                                  First of all, they said "not possible." Scientists, astrophysicists, even Big Foot was scratching his head! Nobody could figure out how to stop the universe from exponentially expanding faster than my rally crowds. But under my leadership, we negotiated the best cosmic deal. We deployed state-of-the-art interest-rate spinners on dark energy, put tariffs on runaway space-time, and - I'm not kidding - built the beautiful galactic wall to keep excess inflation out of the Milky Way!

                                                                                                                                                                  The results? Beautiful. The universe has stabilized. No more exponential bloat! Stars remain at just the right distance, galaxies keep their perfect shape, and astronomers can finally retire their "Big Bang gone wild" theories! Our beautiful Inflation Reduction Act also saved trillions of light-years' worth of energy - making it green, making it lean, and letting us focus on what really matters: making America go WOW again!

                                                                                                                                                                  Now the Fake News Media will try to discredit us: "Impossible!" they'll cry. But we know the truth. We have the best cosmic economists, the smartest black-hole negotiators, and let me tell you, they're all saying the same thing: "Sir, you've done what no one else could!" So join me in celebrating the greatest cosmic achievement in history. We've ELIMINATED inflation, not just here at home, but across the ENTIRE UNIVERSE. That's what winning looks like, folks!

                                                                                                                                                                            And this isn't a matter of "you can do two things at once"; we should provide for our own people _before_ we worry about cosmic inflation.

                                                                                                                                                                            • ac794 2 days ago

Most of that money usually goes to medical research (as it should), which directly improves the quality of life for millions of people. The remainder goes into R&D which drives progress, yielding benefits across many different industries. Slashing the science budget and investing that money in homelessness instead would probably not fix homelessness in HCOL areas (issues are structural) and would end up being a major net negative for the rest of society.

If we hadn't passed it, we could have continued learning about cosmic inflation _and_ helped millions of people regarding food and healthcare and still saved trillions in the process. Of course, America would never do that, but our current issue is no longer "we should be helping people instead of doing unnecessary spending." Now we're squarely in "let's starve everyone of resources and give it all to the 1%."

                                                                                                                                                                                  The debt would have been about $52T+, now it will be $56T+, if projections are accurate.

                                                                                                                                                                                  While I do not agree with the BBB for many reasons, and I do agree that it increases the debt, it is not the primary driver of the debt.

                                                                                                                                                                                  The largest driver of our debt is our "health" system. We spend $5T a year on our "health" system, which is twice the amount per capita that western European nations spend, and we have outcomes that are, across the board, worse.

                                                                                                                                                                                  We spend $2.5T more per year than we "should" be spending on "health", which is by far the largest waste of our resources.

                                                                                                                                                                                  If we would "simply" find a way to spend as much as western Europe does (even keeping our poorer outcomes), we would save $25T over the next 10 years. Our entire national debt could be eliminated in 20 years by doing this, even with the BBB.

There is nothibg preventing the US from doing both other than that the current government is actively opposed to both funding research and helping the homeless.
