Is this the conventional view. I always thought the universe was expanding as a result of the big bang momentum. This expansion would keep going unless there was a critical mass to pull it back. (that was the way things were when i was a kid). Or am i misreading.
- Devilboy 16y agoThe expansion is accelerating though
- a-priori 16y agoFrom http://en.wikipedia.org/wiki/Dark_energy http://en.wikipedia.org/wiki/Dark_energy: "dark energy is a hypothetical form of energy that permeates all of space and tends to increase the rate of expansion of the universe"
- retube 16y agonot sure that quote is correct. Gravity is an attractive force, it should slow expansion. However recent observations indicate the expansion is accelerating. This has (I beleive - been out of modern physics for a little while) lead to the positing of "dark flow", missing or dark energy.
