Gravity...what?

Think of a swimming pool that is the size of the universe. Whether there are boundries, i don't know, but lets just say there is a maximum. Now throw a tennis ball into the water. what do u notice? Well, the tennis ball is floating about halfways into the water. Now get a big beach ball and do the same. Now u see that the beachball is about a quarter of the way (or less) into the water.
Pressure. Once again think of a swimming pool. If u put the a ball into the water, the water will rise. But since there are boundries that will not allow water to seep out, pressure builds up. Pressure builds up, and the ball will feel the stress. Pushing on all sides of the ball to the very center.
If there is a maximum to the size of the universe, and we know that matter can not be created or destroyed (only transformed), pressure is pushing us down on earth, or any planet. The less matter that a planet (or moon or whatever) takes up, the less pressure that pulls toward its core. Small planets have weaker pressure than a huge planet which will have a strong force of gravity. So we shouldn't look into the center of the earth to see if there is energy PULLING us to the floor, but to the pressure in space PUSHING us down.

| and what exactly is pushing us down in a uniform matter? and why to earth in particular? :rolleyes: |

actually, i do believe in gravity
coming to conclusions based on a flawed analogy can get you into trouble
and thats not even to mention the fact that it assumes the universe is finite |

And a ten pound rock sinks to the bottom of the pool. The matter in toto remains the same. Nothing you do here on earth impacts the rest of the universe. Space consists of matter and vacuum in the void. Unless a celestial object interferes with us outside the norm, we are in equilabrium with the rest of the universe and there are no outer forces pushing us down or interfering with us at the moment.
Pass the doobey over here...

Evidence so far indicates that it is finite. |

| the pressure of the universe is pushing us down. We have our general weight of 150 pounds here on earth. So we have X amount of pressure pushing us to the floor. Once we go to a planet that is double in size, there will be double amount of pressure pushing us down, hence, we would weigh more on jupiter than on any smaller chunk of matter, like moons or the smaller planets in our solar system |
