How does gravity actually work
WebOn the one hand you could imagine standing on a really tall, really narrow column. Clearly gravity is weaker at the top, because the column has negligible mass but you've moved significantly further away from the centre of the Earth; On the other hand, imagine adding another layer of crust to the Earth. That's a bit like a really wide mountain. WebWe know gravity is one of the base forces of the universe, just like electromagnetism and the nuclear force that keeps protons and neutrons together. General Relativity describes gravity as some force that bends spacetime around Mass/Energy.
