Why Did Einstein Introduce His Cosmological Constant into the Original

question 73

Multiple Choice

Why did Einstein introduce his cosmological constant into the original field equations for general relativity?

• A) The constant was necessary to make the solutions describe an expanding universe.
• B) Experimental evidence at this time (before Hubble)suggested a static universe,and this constant was required to produce static solutions.
• C) The constant represented the acceleration of gravity near Earth's surface,and it was necessary in order to make the nonrelativistic limit of the solutions compatible with Newton's results.
• D) The constant represented the speed of light,and its inclusion was necessary to produce solutions,which were compatible with the postulates of special relativity.
