Re: Gravity - A different concept
You're post is very entertaining, so I couldn't help but join in. What always made me think of about a hole through the earth is what happens when you drop a ball into it. Of course, the "force" of gravity will diminish as it approaches the center, but after continuing to gain speed, after passing center the bulk of the mass causing gravitational force will be slowing it down as it approaches the other side of the planet surface. The question is, assuming the false ideal, that there is NO friction involved, will the ball continue indefinitely to swing back and forth from one surface of the globe and the other? :) I think so...

This is the idea that prompted me to ponder the mysterious wonder of GRAVITY. Actually that was the second question to come to my mind…spawned by the events following:
While at work one hazy day, I was looking out of my 5th floor window over the roof top of a level below me. The contractors that built the place had placed rocks, about half the size of golf balls, all over the top of the roof... I’ve seen this done before on roofs and to this day don’t understand what it is for…but none the less I was sort of in a “I’ve been thinking to much” daze staring out the window at the rocks. I noticed some of the rocks apart from the others, scattered about on sort of a ledge. Then I started thinking…Here, five stories above the earth, the rock and I were just sitting there…Stopped from falling to the earth by the solid building beneath. If the building were to suddenly vanish, our existence would turn into a chaos of whirling wind for a few split seconds and then sudden impact with the planet. Bad for me more so than the rock of course, but it is just that thought that got me going. What the heck is Gravity?
What is the force that attracts us to the earth? Is it indeed a pull? Or, is it a push? That is when the second thought came into my mind. What if there was a hole clear through the center of the earth...how would something react falling through the hole? Would it fall half way and stop in the middle? I don’t think it would go through and come out the other side. Or would the hole totally negate the earth’s gravitational force? Think about this a minute or two…it kind of twists your mind a bit.
What is going on for everything, including the earth, to be in such a race to go inward? Everything I know of, with the exception of helium (and other gases), is attracted to the center of our great and wonderful planet. And it seems the greater the density the stronger this force becomes. Why?
If I were to build a giant sphere in space, out of plastic, the size of our moon or earth…would it have its own gravitational force? Or does it have to be made out of rock and dirt? If it does have its own force, what caused it? I didn’t add anything special to the plastic to give it gravity.
That idea started me to thinking about just what gravity is. If I don’t have to add anything but mass and density to get gravity what is causing the attraction or inward push? Could it be that I’ve taken up space. Just as if you were to introduce a sphere into water, it would move the water out and away…but when you remove the sphere from the water, the water takes back the space that was occupied by the sphere. I think that is what is happening with space. Even if it is space it has its own place in space. It wants the space back. So it pushes inward on the mass and everything around it trying to re-occupy the space that was invaded by the mass.
There you have it…my basic concept on gravity. It’s the force of Space that has been occupied by mass trying to reclaim itself against the mass. This force is relatively weak on a small scale, but grows more and more powerful the bigger the mass gets.
Think of it as placing a large ball inside a smaller balloon that has not been blown up. You would have to stretch the balloon over the ball. The rubber would squeeze anything between it and the ball trying desperately to get back to its original shape. That is what is happening in space. The earth is taking up space and the space that has been squeezed out of shape is pushing in to reclaim its original shape and space.
Einstein himself theorized that time and space is warped by gravity. But I think time and space are warped by mass. If you look at a visual model of Einstein’s theory of this warping of space, it is always shown as if the world is like a heavy ball laying on a piece of fabric…bending the fabric down warping space and time. Think of this same visual…but this time there is another piece of fabric on top of the other and the ball is moving in between the fabrics. Space would cover the ball all around…not just under the ball…bending space and time around the ball.
It is mass that is distorting time and space caused by the force of space trying to re-occupy its rightful space against mass. Which is what is known as gravity.
There is a reference above stating that Einstein himself theorized time and space is warped by gravity... I'm not exactly sure that is truly what he theorized. He may have said that Mass is what warps time and space. And with this I agree. It is the gravitational effect that I believe actually warps space/time.
I need to state, as you will probably surmise that I am not a scientist and have no degree in science other than computer science. So my statements are what I believe to be the possible cause of gravity based on my own reasonable and layman deductions. I welcome all comments.
And by the way…I think that if there were a hole, completely through the center of the earth, that gravity would then push in on the exposed earth throughout the center…meaning one would be able to then walk to china…in a spiral.
