Are collisions with the energy levels of LHC happening in our modern day Universe? Like at the core of stars or at the event horizon of black holes where a lot of high energy stuff is going on?
Sorry for the naive question, I'm extremely interested in physics but I'm just not proficient...
I mean, several light years from here, is it possible to distinguish between the signals coming from Earth and the massive amount of electromagnetic radiation emitted by our Sun? From a great distance, every solar system must appear dot-like.
Is it possible that civilizations are actually...
Wikipedia says that the core temperature of our Sun is 15.7×10^6 Kelvins.
I don't know what that means in terms of protons' velocities inside the core, but I bet they move pretty fast. Could they move that fast that they have a noticeable increase in mass due to their relativistic speed...
