Cosmological Constant: Expanding Universe & Data Contradiction

[QUOTE="Orodruin, post: 5484683, member: 510075"] No, the presence of dark [I]energy[/I] causes acceleration. Dark matter is a regular matter component which causes deceleration. Dark matter and dark energy are [I]very[/I] different concepts. Einstein's introduction of the cosmological constant was to get a static universe. However, this only occurs for a very particular value for the cosmological constant and the solution is anyway unstable. There is no contradiction in having a cosmological constant and an expanding universe. [/QUOTE]
