Truth be told none of us know exactly the repercussions of smashing these particles together.
Yes, we have sensors to detect a lot of theoretical things... But I refuse to believe for a moment humanity has "figured this out" in any means.
For every collision that happens there very well COULD be some nasty little particle released that does something unexpected. We truly don't know. I know personally this is more of a "what if" rather than a concrete ideal.. But in the land of "what if" and speculation something like this device could in fact (maybe) create ripples in time and space.
But we did figure out. We are producing particles we know a lot about, how they interact with the detector material, etc. We can reconstruct everything that is going on in there. And it is not only theory, but also experiment. And the unknown is exciting. But don't imagine the unknown will go very far (see below).
Which would be great. There are many new physics theories that are just waiting for these new phenomena. New particles will either interact with the detector and then will not leave it and decay into Standard Model particles. Or they will leave the detector invisibly, like dark matter. But this means it does not interact with normal matter (only very very rarely which is why we have not managed to observe it so far, in particular in direct detection experiment as dark matter particle are going through Earth constantly, unnoticed (like neutrinos by the way that we know for sure they exist)).
No it can't create any ripple. For this, you need either mass, or energy, or both. We don't have any of those (in an amount significant enough to alter spacetime) at the LHC. You have natural particle physics phenomena with an energy billions times larger than the one of the LHC. And those have not even alter anything. Then at the LHC... this is simple: no way.
As someone who seems highly educated on the matter this seems like an odd things to say.
I can't help but think that smashing the very glue of matter apart would yield at the very least something that would be able to interact with particles around it other than just the detectors as you are stating.
I had read about "force" particles of some type as well as some other odd particles that seemingly get ripped towards the earths core after testing..
Surely you are better educated than I am on this matter..! But completely discrediting something like this where you do have mass and energy colliding at near light speeds... Well I'm not entirely sold either way on it. :/
Sorry for my language. I should have explained more. Dark matter interacts gravitationally like ordinary matter. But it is not normal matter in the sense it does not interact electromagnetically or via weak interactions. That's the only reason of my 'normal'. :) I hope this makes it clearer.
Which particle other than detectors? Because there are actually none of those. The vacuum conditions in the LHC are such that you have the beams, and our detectors.
You have force carriers in the Standard Model that are the particles responsible for mediating the fundamental interactions. For the rest, I have no clue what you are talking about. If you can provide some article I could read, I could probably comment better :)
The energy there is not that huge. An LHC collision as roughly the energy of two high-speed trains that would collide. It is not such enormous. As said above, you have many phenomena (macroscopic and microscopic) at much larger energies.
Finally, I am not discrediting everything. Using false memories is one thing, but writing that tens of thousands of particle physicists from all around the world are trying to manipulate the human memories... That's too much for me. I cannot believe in this before seeing any proof.
