OK, so every particle of matter attracts every other particle of matter. But why? Why doesn't matter just mind its own business and not bother any other bits of matter? Cosmic busybodies. Matter must be "Progressive."
And why does light keep traveling for billions of years? Don't the light beams ever get tired?
Describing the effects of Gravity is not the same as knowing what it is.
Gravity is just the label we put on something that we don’t know how it works but know that it does.
Mass depresses the fabric of space-time, creating a ‘gravity well’, or so they tell us. Every bit of mass depresses it to some extent.
If you had a universe where only two atoms of hydrogen existed, and they were a billion light years apart, they would eventually collide or settle into a stable orbit around a central point............
All good questions which have occurred to me as well. In my opinion our current understanding of the actual mechanics of reality is about the same as a dog staring at a ceiling fan. He knows that there's something there but doesn't have a clue just what it is.
Here’s another one. Maybe I’m just to stupid but can a photon be stationary next to a specific object? Say a rock, person or tree.
