(physics)
Hypothetical repulsion of matter and antimatter; however, experimental results indicate that matter and antimatter attract according to the same laws as matter and matter.

Here we shall use an exclusively geometric description, but will nevetheless be able to demonstrate, by studying the particle geodesics inside the shell, that the picture which emerges almost demands that we accept there is gravitational repulsion in the interior of the shell.
In particular, if w is less than -1 at some time in the future, dark energy density will grow to infinity in finite time, and its gravitational repulsion will tear apart all the objects in the Universe.
If so, one may ask another interesting question: "How about the destinies of the gravitationally bound objects in the Universe, such as galaxies and stars?" In fact, if w indeed ever becomes less than -1, dark energy's gravitational repulsion will continuously increase until it overcomes all forces holding objects together and all objects will be torn apart.

"It's the gravitational repulsion of the false vacuum that drives the expansion," Guth says.
(2) shows that gravitational repulsion occurs between bodies when their masses m are increased by converting radiation energy into mass.

The increasingly negative QCM gravitational potential dictates a non-linear redshift with distance and an apparent gravitational repulsion. No space expansion is necessary.
