What creates the gravity?

Question

Why two objects (matter, mass) in the space pulls eachother? what is the reason of it. What causes the gravity

Answer 1

In order to answer your question a person needs to know why a field of gravity forms. First of all, Stephen Hawking in "A Brief History of Time," page 92, paragraph 3, states; "Like light, gravitational waves carry energy away from the objects that emit them." So, a field of gravity is a particular form of energy. This form of energy is described in the physics trilogy, which is: E = mc2, m = E/c2, and c2 = E/m. The last is that of a field of gravity or that of a field of time. It is an energy/mass relationship.

The form of energy spoken of in the equation is that of the heat energy contained within a mass. The greater the heat energy, the greater the field of gravity. Were a mass the size of our planet to have no heat energy within it, then it would have no field of gravity about it. Were the heat energy to increase, the force would increase.

Our sun expends 665 lbs/sec in order to keep the planets in place about it, and our planet expends 0.00444 kg/sec in order to keep us in place about it. There is an experiment that was performed a few weeks ago that proves a field of gravity is able to be formed and collapsed. It is found at http://youtube.com and the name of the experiment is "successful gravity experiment". It had to be posted in segments because of time restrictions, so it needs to be put back together.

Answer 2

This is one of the biggest questions in all science, and is still not completely resolved.

There are four forces in physics: Electro-magnetic, strong nuclear, weak nuclear and gravity. Gravity is very much weaker than the other four, and there is some debate whether it is a force at all, in the same way as the other three are.

According to Einstein's general theory of relativity, gravity is actually a 'warp' in space-time caused by the presence of matter; which causes massive bodies to attract other bodies towards them.
An easy way of visuallising this is to think of a heavy metal ball resting on a thin rubber sheet. The sheet will stretch and distort near the ball, and any other ball lying on the sheet nearby will run down the depression, towards the heavy ball. Further away, the slope of the rubber sheet will be much less, and the effect on balls further away will be a lot less. Gravity works in much the same way in three dimensions.

Answer 3

@Zykanthos: ... Are you feckin' kidding me? Maybe if you believe in a non-local universe, but after the EPR I don't see how you possibly could be without also rejecting realism; and GOOD LUCK with that. OP has a good point to make. Did Universal laws/forces exist before the Universe? Common sense would dictate, yes. But then where did those laws/forces come from, and where did the matter that they interact with come from in the first place? Ah yes, and for all of you "scientific geniuses", particles DO NOT just pop in and out of existence. Their waveforms collapse after observation which means that unless you accept the locality of particle existence in a definite manner WITHOUT Hidden-variables you are rejecting counterfactual definiteness, and you can never EVER be sure that the particle being observed is actually observed with the properties inherent to the measurement. If you're going to make a claim, maybe you should actually know about the topic you're making a claim on.

Answer 4

Gravity by uniting three-dimensional space and time into four dimensions that together create an elastic fabric of reality called space-time that is warped by the energy it contains. In this theory, mass is one form of energy, creates gravity by warping space-time.

Answer 5

Gravity is just a way of life like: evolution and something like that.
