@AndresSalas One way to look at it is to say the gravitational field fills space, so wherever you are, you're already being affected by it all the time. ... technically. Changes in the geometry of spacetime actually propagate at the speed of light, but the apparent effects of gravitation end up being instantaneous in all real-world dynamical systems

That's why objects will still experience gravity when a distortion occurs until the distortion ripple reaches them at a speed, seemingly c. I'm not super moved as to these observations being issues, you know? But I do wonder why a planet reacts to someone else absorbing their emitted particles, where does teh pushback come from? | |

Who's to say he didn't just walk into a stream of particles with any speed? If I walk into a shower and the water hits me fast it doesn't mean the stream of water has a light speed, it means it was already partways through its pilgrimage from top to bottom. And boy did I not read the whole shebang, but +1 for thoroughness eh. Feel free to show me what I should read in your post good work | |
