New Clues About the Nature of Dark Energy: Einstein May Have Been Right After All

The good news from NASA's Hubble Space Telescope is that Einstein was right — maybe. A strange form of energy called "dark energy" is looking a little more like the repulsive force that Einstein theorized in an attempt to balance the universe against its own gravity. Even if Einstein turns out to be wrong, the universe's dark energy probably won't destroy the universe any sooner than about 30 billion years from now, say Hubble researchers.
