Can the cause of gravity exist without the presence of a mass structure in the Universe?

Answer 1

Gravity is a manifestation of space in the presence of matter

Answer 2

The direct answer is that the force of gravity is a product of a mass to energy relationship. This is seen 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 physical time. These two are the same concept having different names. Notice that were a mass to have no energy (heat energy) then there could be no field of gravity propagated. Were a mass the size of our planet to have no heat energy within, then that mass would have no field of gravity about it.

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.” Notice that the force of gravity performs work and in order for work to be performed there must be an energy source. If there is not an energy source then the force of gravity must be being created in all mass at all times. Either there is an energy source that forms a field of gravity in the presence of mass or there is continual creation. There is a short, easy to read writing at http://360.yahoo.com/noddarc entitled "An Experiment You Can Help With" that may be of interest to you, explaining by manner of experiment why it takes both mass and energy in forming a field of gravity.

Answer 3

No. Einstein's theories of relativity point out the fact that gravity arises from the warping of space, which is only caused by the presence of mass. Were there no mass in the universe, there would be no gravity.

Answer 4

In the view of our present day understanding of gravity, that it is due to the space-time distortion, it is clear that gravity can not exist without mass (or anything as long as it was not emitting 'gravitons').

Answer 5

No, it needs mass to exist, unless you can invent an alternative gravity source.

Answer 6

No. Gravity is a property of mass.
