I have often wondered about the relevance of velocity relative to gravitation, even when free fall produces weightlessness. E.g. if you are orbitting a black hole near the event horizon, you are in free fall but you are approaching the speed of light as well. So the velocity needed to ...
Perihelionis the point of the Earth’s orbit that isnearestto the Sun. This always happens in early January, about 2 weeks after theDecember Solstice. The words come from ancient Greek, in whichheliosmeans “Sun,”apomeans “far,” andperimeans “close.” ...
