Hi,
We know from Einstein's GR that gravity bends spacetime and that curvature effect makes other masses "fall" down that curvature and orbit around it. But I can't understand how that affects everyday life, like why are we attracted to the Earth, no matter where we are. A guy in the north pole is attracted to the Earth as much as someone in the south pole and we now know that gravity is not an attraction force. So how can we illustrate that effect? I've seen those videos where they show a planet causing a bump in the spacetime and all the planets orbiting around it, falling to that curve, without ever reaching it. But how does that explain that we are attracted to the Earth, no matter where in the planet we are? I'm sorry if this is a stupid question, but I'd really like to understand it.
Thanks in advanced!
