SmallishBeans, Grian, GoodTimesWIthScar, Zyph, Deosil25, and 6ProUp4 are the best. I was only gonna put 5 but I couldn't leave 6ProUp4 out, he is absolutely incredible!
2d shapes really don't exist because if one of the dimensions like 'z' equaled zero it wouldn't exist. So if there were 4d shapes... 3d would cease to exist. so maybe we don't exist...
I've heard that if you go faster than light (like you ride on light and you walk one more step to go faster) you would go backwards in time, meaning you can't go faster than light. Is this true?
