More on Cosmological constant

A constant introduced by Einstein  (1917) into the equations of general relativity to allow a steady state cosmological solution to the Einstein field equations. The constant was introduced before the concept of the Big Bang had been conceived, so an expanding or contracting universe  was regarded as physically implausible, leading Einstein to add as a … Continue reading More on Cosmological constant

Eric Cornell, one of three winners of the 2001 Nobel Prize for Physics, designing 'toy' black hole for research

Eric Cornell, one of three winners of the 2001 Nobel Prize for Physics, said that he was in the process of developing a ‘toy’black hole. This would help in a better understanding of theories around the space body. In 1915, Albert Einstein first published the general theory of relativity. Among the astrophysical implications of that … Continue reading Eric Cornell, one of three winners of the 2001 Nobel Prize for Physics, designing 'toy' black hole for research
