WebDark Energy was discovered in 1998 when two separate teams of astronomers (see here and here) studied Type Ia supernovae. The use of Type Ia supernovae is particularly … The "cosmological constant" is a constant term that can be added to Einstein field equations of general relativity. If considered as a "source term" in the field equation, it can be viewed as equivalent to the mass of empty space (which conceptually could be either positive or negative), or "vacuum energy". The cosmological constant was first proposed by Einstein as a mechanism to o…

WebSep 18, 2014 · One way scientists indirectly study dark matter is by using gravitational lensing. Light going through a gravitational lens is similar to light going through an optical lens: It gets bent. When light from distant stars passes through a galaxy or cluster, the gravity of the matter present in the galaxy or cluster causes the light to bend.
