But we have a lot of educated guesses, and a lot of ideas for how to find out more. So, most physicists think that dark matter is a particle, similar in many ways to the subatomic particles that we know of, like protons a...
So, one aspect of string theory, at its simplest form, is this:matter is made up of atoms, which are made up of protons and neutrons and electrons, which are made up of quark. 特别是关于弦理论。我知道它只是许多理论之一,但它会对我说话。所以,...
