Gravity speculation

Recommended Posts

I just had an idea. What if gravity is two forces instead of one?

The primary force: An incompatibility between spacetime and matter. Spacetime repelling matter.

The secondary force: Matter attracting matter. Being the same it wants to unite. (Surrounded by repelling spacetime.)

It's a bit like water and oil.

Stupid?

A little bit wrong. Space-time repels both matter and itself. Matter attracts both matter and space-time, or holds space-time around it. In other words, the mass of matter is positive, and space-time mass is negative.

That sounds even more stupid than my idea. Sorry pal. Please let the pro's give their opinion.

Sounds almost like GR ...

Einstein incorporated two mechanisms into his theory; at the time, he thought mistakenly.
One part is a geometric field, which manifests as space-time curvature, and is responsible for test masses following curved geodesics such that masses seem to 'attract' each other. This is a simplification that ignores many other effects.
The other part, he 'tacked on' as the Cosmological Constant, and it may be responsible for increasing separation between galaxies/clusters and universal expansion. As we are not quite sure, it is commonly known as Dark Energy.

It is not possible to capture all the necessary degrees of freedom for gravity using vectors fields - irrespective of whether there is just one vector field (=Newtonian gravity), or several. For fundamental reasons, you need at least a rank-2 tensor field - not least because the source term is itself a rank-2 tensor field.

To put it simply - gravity is not a force.
