| Subject: Dark Energy Is Driving Universe Apart! Fri 20 May 2011, 8:23 am | |
| Dark energy works -- as a constant force, uniformly affecting the universe and propelling its runaway expansion. They contradict an alternate theory, where gravity, not dark energy, is the force pushing space apart. According to this alternate theory, with which the new survey results are not consistent, Albert Einstein's concept of gravity is wrong, and gravity becomes repulsive instead of attractive when acting at great distances. "The action of dark energy is as if you threw a ball up in the air, and it kept speeding upward into the sky faster and faster." Dark energy is thought to dominate our universe, making up about 74 percent of it. Dark matter, a slightly less mysterious substance, accounts for 22 percent. So-called normal matter, anything with atoms, or the stuff that makes up living creatures, planets and stars, is only approximately four percent of the cosmos.http://www.sciencedaily.com/releases/2011/05/110519113152.htm |
