Does Dark matter helps in proving string theory?

0

First, yes dark matter is made of something besides neutrons, protons, or electrons. However, at the present moment there is not enough known about dark matter to know whether the particles that make it up are anything different from the particles that are proposed by theories that would not necessarily require string theory. That is, once one finds out what the particles are, one will see if string theory is consistent with their existence, but that alone would not help prove string theory unless string theory turns out to be the only possible theory which would be consistent with these particles’ existence. As it stands now, there is no reason for this to be assumed to be the case. In other words, at the moment the existence of dark matter does not prove the validity of string theory. But watch for developments.

Dark Matter , is it possible that they are made of particles other than neutron proton or electron? I don’t see how it can. The fact is, “dark matter” comes from trying to find an explanation as to the internal dynamics of galaxies (observed startfield speeds versus the mass calculated from star densities, assuming each star has more or less 1 solar mass). But it says nothing about the nature of “dark mass”, it’s just postulated that it emits/reflects no EM radiation (hence is “dark”). It might be ordinary matter, although that wouldn’t explain why “some” matter is “seen” and “some” isn’t. String theory comes from trying to bring together quantum field theory AND general relativity. For example, in QFT particles are assumed as points, so it makes little sense how they can “touch” and interact (as happens when you “draw” a vertex of a Feynman diagram). If we assume that the objects have a certain extension, they can “spread out” as per the Heisenberg uncertainty principle
