Is there something that is not affected by gravity?

[L.A.F.]

In other words, is there something that is not affected by the gravitational force, no matter how strong the latter is?

Dark energy in theory.

Dark energy in theory.

Not in any theory familiar to physicists.

In fact, dark energy is thought to be effected only by gravity and none of the other 3 elementary forces known to physics.

Wrong. Dark energy is thought to be effected only by gravity and none of the other elementary forces known to physics.

None that we know.

This is not surprising because our only really successful model for modeling and predicting elementary makeup of the universe - known as the standard model of particle physics - does not give a description of how gravity fit into the scheme of interaction between different constituents of the universe. As a result we don't have any theoretical foundation to say where we should even look,of we were to try to find something that is totally uneffected by gravity.

Did you even read any of these?

Dark energy menifest itself as a negative pressure intrinsic to space. By relativity Gravity interacts with pressure just as it interacts with any energy such as mass. It is only because of this that Einstein had anything to say about "cosmological constant" and why we can say that dark energy excert its effect as "negative gravity" and propels the acceleration in the expansion of the universe.

If it weren't for the fact dark energy interacts with gravity, we would have absolutely nothing to say about it.

Gravity is not a force. Even Newton realized his equation for calling gravity a force was by faking his gravitational constant. Einstein's idea of it really being a distortion of space is still passing every test of it. Quite amazing really.

Which leads to everything passing through (particle) or propagating (wave) through space must also travel through the distortion of space. At the moment this appears to describe everything including dark matter and energy. Therefore everything is affected.

The fun thing at the moment is it is finally possible to see if anti-matter is also anti-gravity, negative mass to speak. Maybe results in a year or two. Going to be interesting.

What of Neutrinos?





Just curious.

They travel through distorted space therefore they are affected by gravity which is distorted space. Pretty straight forward actually.
