Aki Posted March 15, 2005 Report Share Posted March 15, 2005 The expansion of the universe is indeed accelerating. The red-shift tells us that the universe is expanding (doppler shift: red has the longest wavelength). There is something called the "dark energy" that causes the expansion to accelerate. Dark energy is the opposite of gravity. While gravity pulls in everything together, dark energy opposes that and pulls everything away. here is a related article:http://www.space.com/scienceastronomy/astronomy/universe_expansion_020320.html Quote Link to comment Share on other sites More sharing options...
