My background is in CS, not physics, but I dabble a bit. I am hoping to confirm a few things I have read and think that I understand. I am hoping these are easy questions. I will try to make them yes or no questions. 1) If one travels close to the speed of light, then time slows down? 2) Einstein predicted that gravity is just a distortion of spacetime? 3) The inertia of an object is related to its mass? 4) The speed of light through an object is slower than the speed of light in a vacuum? 5) We have successfully accelerated particles damn near the speed of light? If so how close? 6) We have accelerated particles faster than the slower speed of light through objects? Thanks, I am looking many of these up as well.
