Next-generation LHC: CERN lays out plans for €21-billion super-collider
CERN has unveiled its bold dream to build a new accelerator nearly four times as long as its 27-kilometer Large Hadron Collider—currently the world's largest—and up to six times more powerful.
The European particle physics laboratory, outside Geneva, Switzerland, outlined the plan in a technical report on 15 January.
The document offers several preliminary designs for a Future Circular Collider (FCC)—which would be the most powerful particle-smasher ever built—with different types of colliders ranging in cost from around €9 billion (US$10.2 billion) to €21 billion. It is the lab's opening bid in a priority-setting process over the next two years, called the European Strategy Update for Particle Physics, and it will affect the field's future well into the second half of the century.
[...] Not everyone is convinced the super collider is a good investment. "There is no reason to think that there should be new physics in the energy regime that such a collider would reach," says Sabine Hossenfelder, a theoretical physics at Frankfurt Institute for Advanced Studies in Germany. "That's the nightmare that everyone has on their mind but doesn't want to speak about."
Hossenfelder says that the large sums involved might be better spent on other types of huge facilities. For example, she says that placing a major radio telescope on the far side of the Moon, or a gravitational-wave detector in orbit, would be safer bets in terms of their return on science.

Yes, but if we end by creating more dark matter in a controlled manner, we may slow the speed of Universe expansion!
Now, that is long term thinking!

OK, you are probably going to think I am going nuts, and you are probably right, but what you are saying makes too much sense to me. I've been reading this blog so much the last week or so, that I have to stop myself almost daily from writing to Sabine (out of the cold) about how much sense this shit makes and what I think about it. And my latest Bordeaux-inspired idea is that there is this kind of fucked up reflection of the universe into itself on a distant (perhaps Planck) scale, where what we see as the large-scale structure stabilizes somehow and becomes the quantum foam of the universe we seem to observe with telescopes. And these cosmic filaments of galaxies and clusters literally vibrate due to the interplay of positive and negative gravity (even Susskind says dark energy gravitates, so even he believes in negative gravity without quite saying so), sending out waves and whatnot, and these waves and related events are perceived by us, on our level, as the particle physics.
The reflection goes kind of like this: the 100 million light years or so, the end-of-greatness scale, where a stable foamy structure seems to emerge, let's say that's somewhere in the neighborhood of the Planck scale, and so the large-scale structure we currently observe is like 150 Planck times since the big bang. If inflation has happened, then the universe expanded by a factor of about 10^26, which corresponds to the large scale structure homogenizing and creating a foam with bubbles roughly 1mm across. This sounds pretty unreasonable until you realize that we are in fact still expanding, and accelerating, and the inflation (the foaming) hasn't even began, and so by the time the foam finally emerges, the radius of a cell could strecth out to astronomical length. To boot, we don't know absolutely anything about dark energy, so it's quite plausible that the whole shebang starts contracting again at some point, and things get real foamy, which brings me to my final point:
If you are still reading this (can't really blame you if you are not), here's the reason I found your post so resonating: the universe, as we know, is expanding, and the large-scale structure is being blown apart, so there's a problem right there. How can the quantum foam form? Well, what if the currently stable structures, the galaxy clusters, start doing something really weird due to the presence of carbon-based life? What if clusters actually start redistributing the matter in the universe by flinging galaxies into the voids or whatnot, and that in turn slows down the expansion and brings the large-scale structure to a stable state? With this kind of reflection, it becomes at least plausible that the chemical life, which at this point seems to be likely spread evenly across the observable universe, at some point gets to determine (as in: design) what the laws of physics are.
Now put THIS in your pipe and smoke it.

You know, that sounds exactly like what I was thinking when I came up with the Heliocentric model of the solar system. Only, it turns out, I was right. I wish you equal success with your theorizing. Of course, you could just be crazy.

Science doesnt care if you are crazy? However you do need to get a testable prediction out of the theory... Preferably something quantitative and precise.
P.S. the geocentric and heliocentric models of the solar system are equivalent. They are both correct, just using different reference frames. Humans generally prefer the aesthetics of the heliocentric model though and find it easier to work with.

Using different reference frames, one of which is just wrong, unless for religious reasons. And you have the hubris to question aristarchus? I gave the quantitative predictions, and given what I was working with, they were pretty spot on. So what perverse aesthetics do you prefer to work with, oh dark and non-enlightened AC?

You who are so wise in the ways of science should not pose such a stupid question. There are some who seek to maintain the geocentric model by citing Einstein, and claiming that the center of the universe is arbitrary, so we could justifiably just pick earth as the center. [discovermagazine.com] [Plus, this would verify scripture, which seems silly and stupid otherwise.] But, there are Einsteinian problems with this.
For example, if the earth is the center of the universe, and discounting daily motion, which there really is no reason to do, we have to admit that galaxies, some which are at distances of 13 Billion light-years distant, orbit the earth once a year. I would leave the math to such a wise and opulent AC such as yourself, but what would you calculate the velocity of NGC 3034 [wikipedia.org]? And you are certainly aware that Einstein's constant, the C in the E=MC2, is the speed of light. So how is it that the Cigar Galaxy can cover. . . . Yes, Geo-centrism is absurd, silly. Quite close to the Electric Universe or Flat-earthers. So, no, I am not a relativity denier, and neither should you be.

If two trains are traveling towards each other at near the speed of light isnt their relative velocity ~2c?
The answer is no, and for the same reason your far away galaxies moving really fast relative to earth is not an issue.
Also, the only one bringing up religion is you. You think Ptolemy cared about christianity? I can care less about it other than it seems to somewhat defend against a majority of people treating their political party or government like the ultimate authority on everything.

What is that reason? There is no 2x the speed of light? Therefore: . . . what?
Oh, come now! But not in my mouth. Religion is what all these wacko theories are about. Why, for instance, would it be important, or even relevant, to make an argument for the Earth being the center of the Universe, unless you perhaps believed that the purpose of the creation of the Universe was to create this one insignificant planet, and grow some sort of self-conscious slime [They're Made out of Meat" [youtube.com]] that could conceive of itself as the sole purpose of a vast and expanding universe.
So again, it is the irrational forces that try to deny science, deny things like global warming and the insanity of Donald J. Trump. And history proves them wrong, as you will be proven wrong. Galaxies cannot exceed the speed of light, nor can the light from the galaxies exceed the speed of light. You need to reconsider your entire position, and perhaps update your life insurance. Or perhaps you are like the Orphelai? Or the Wedilai, only part meat? No brain, eh? Oh, there's a brain alright, but it's made of meat.

Or... we could be in a computer simulation, with limited resources, so that as our capacity to observe increases, the simulation must lower the 'volume' that we can observe to still offer us a consistent continuous view of the 'real world'. Every space telescope that we put in orbit will just increase the speed of 'Universe expansion' so that we'll observe less and less in increased details.
(grin)
Of course, we still continue to think the 'universal constants' are universal. We don't have any experimental proof the 'maximum speed of interaction' is the same nearby the Solar system and closer to the galactic core. In fact, as we sit tight around a puny star, can we distinguish between an 'expanding universe' scenario and the one of 'diminished speed of light/gravity towards the margins of the Universe'?
