I was listening to The Infinite Monkey Cage on the BBC and they were talking about general relativity and gravity.
They were saying that gravity is not a force as Newtonian laws describe and is at odds with your real world experience. They said that if you are sitting on a chair, you don't feel a force pulling you down onto the chair. You feel the chair pushing up onto your bottom - at least that's what it feels like when you sit down and try it. They seem to be saying that gravity is not a force pulling from the center of the Earth, it's me that's still and the chair pushing up against me due to acceleration.
My question is if this description is accurate or have I misunderstood this?
If you are sitting on a chair, is what we call gravity actually the chair accelerating up onto me due to the geometry of Space Time?
Is there a better analogy for this?
