Earlier I made a long post about the universe being in a sphere or a cube. Basically a contained area that would allow everything to gather again and create a big bang. I was thinking about it some more. With gravity always being a constant force wouldn't it be inevitable for everything to stop...

Does the passage of time get slower when you go deep into the earth?

I know that Einstien's gravitational well theory is a topographical map of how gravity works. Well what is under the surface of this map he uses. The map looks like a graph with an object on it that warps the fabric of space whenever it's on it. I wonder what's below the fabric of space. Does...

I am a complete novice when it comes to any kind of topic relating to Physical Science- however, recently I came across an idea I couldn't seem to fully grasp. Perhaps some people on this message board can help me out. I have often heard the statement "black holes are so powerful, in fact...

I am a bit skeptical about Gravitational wells. If the sun has a gravtitational well, then the planets should have them too. If the planet's gravitational wells are connected together, shouldn't they somehow remain stationary? That's why I'm not sure whether or not the gravitational well theory...
