Dark Energy = Clue to Anti-Gravity

Here it is...more and more evidence coming in that the gravity-pull we observe within our galaxy may have an antigravity-push complement in the spaces between galaxies! It seems the notion of "one-way gravity" is on the ropes.

And if "antigravity" exists in a natural state, such that it is pushing galaxies away from us, then certainly we ought to be able to create such forces in a lab.

Our perceptions of reality, they are a-changing! /ttiforum/images/graemlins/smile.gif

"Cosmologists in the US have made the most accurate measurements ever of how dark energy varies with time -- and found that it remains perfectly constant. Yun Wang at the University of Oklahoma and Max Tegmark at the University of Pennsylvania performed numerical simulations on observational data from supernovae, the cosmic microwave background and galaxy clusters. The results, which agree with Einstein's predictions for a non-varying cosmological constant, lend further support to the existence of dark energy (Phys. Rev. Lett. 92 241302)."

I had always assumed that gravity had an opposite force. Just like magnets stick on one side and won't on the other.
