question 90

Multiple Choice

Einstein introduced a "cosmological constant" into his formulation of the structure of the universe as described by his general theory of relativity. How did he envision that the cosmological constant would manifest itself?

• A) as many "white holes" that would contribute matter to an expanding universe to maintain constant density, as required by the cosmological principle-a continuous-creation universe
• B) as an extra "gravity" that would hold the universe against continuous expansion
• C) as antimatter that, by annihilating real matter, would translate matter into energy, thereby maintaining a constant mass density in a condensing universe
• D) as a form of energy that, on its own, would make the universe expand-a form of antigravity
