EMDrives are claimed to be propellentless space propulsion systems. If propellentless propulsion is possible it could enable fast human travel throughout the solar system and possible interstellar ...

Supercomputer simulations of galaxies have shown that Einstein's theory of General Relativity might not be the only way to explain how gravity works or how galaxies form. Physicists at Durham ...

A "New Theory of Everything" aims to advance and improve our understanding of gravity beyond what we know from Einstein's Theory of Relativity. For years, scientists have tried to combine gravity with ...

The cosmological constant problem, or the vacuum catastrophe is a discrepency in the observed values of the vaccuum energy density and its theoretical predictions. The solution may lie in the very ...
