"The greatest deception men suffer is from their own opinions" - Leonardo da Vinci
"I think I use the term “radical” rather loosely, just for emphasis. If you describe yourself as “atheist,” some people will say, “Don’t you mean ‘agnostic’?” I have to reply that I really do mean atheist, I really do not believe that there is a god; in fact, I am convinced that there is not a god (a subtle difference). I see not a shred of evidence to suggest that there is one ... etc., etc. It’s easier to say that I am a radical atheist, just to signal that I really mean it, have thought about it a great deal, and that it’s an opinion I hold seriously." - Douglas Adams (and I echo the sentiment)

There's no particle beam in the world strong enough to go through that dense a target...

Large Hadron Collider refit to solve more questions
Until it can answer important questions like, Who wrote the book of love?, or, Who let the dogs out?, I consider the LHC a complete failure.

Always happy to hear from a professional. dumb it down a bit for us lay-people tho, wouldja? I can't always tell a subatomic particle from a subway sandwich.

![[Image: 1e0657.png]](https://images.weserv.nl/?url=www.perimeterinstitute.ca%2Fpersonal%2Fjbrownstein%2Fmog%2Fprediction%2F1e0657.png)
We observe here two galaxy clusters which have collided 100 million years ago and have since separated. The hot gas which makes up the majority of matter was ripped away from between the stars through friction, and is made visible as pink. The strength of gravity is made visible in blue from gravity lensing effects, and you can plainly see that it does not align with the hot gas any more. This is a very strong indication that some frictionless dark matter has moved on beyond the pink gaseous shockwaves and exerts the majority of gravity.
Such effects of separation between gravity and matter cannot easily be obtained by modifying the way ordinary matter produces gravity - a new type of non-radiating matter is a much more parsimonious and predictive explanation.
OK, this is a total mind-blower.
One thing that puzzles me is the use of the word "matter" to describe the - source? - of the additional gravity - waves? When I see something like "frictionless dark matter" I'm transported back to Physics 101, "given an infinite frictionless plain..."
Am I correct in thinking that the word "matter" as used in this context is simply convenient shorthand for "whatever it is that explains the existence of gravity which is more than that produced by the matter which can be detected by current instruments," or is the "dark matter" actually assumed to be matter/mass in the classic sense of E=MC 2?
Because "frictionless matter" just makes my head try to turn inside-out.
Quote:The LHC can find evidence for dark matter through so-called "missing transverse momentum", which means that the momentum of produced particles seemingly does not balance out. This is evidence for having produced a new type of particle which has a relatively long or infinite lifetime and is invisible to detectors. We do indeed observe such missing momentum signatures at the LHC, but we already know particles which have such an effect, namely neutrinos (which cannot provide the majority of Dark Matter because they are too light and too hot). However, we can precisely calculate the missing momentum expected from Neutrinos and then look for additional signatures. So far, none have been found.
If the LHC fails to find such signatures, this does merely mean that dark matter particles, if they exist, do not have properties suitable for observation at hadron colliders of that energy. They could either be too heavy, or too weakly interacting to be produced copiously.
If I'm understanding correctly, the gist is that we can infer the existence of otherwise-undetectable subatomic particles by how they (or their absence) affect the detectable particles when we blow tiny stuff to smithereens at high velocity.
Question: If the LHC fails to find any signatures of dark matter particles, is there any current thinking as to what sort of alternative method might be used to detect them?
Yours in humble ignorance,
Sean
