Answer 2

Greene explains the enigma of dark energy, which is accelerating the expansion of the cosmos.

Explanation:

Professor Greene is well-known in the field of superstring theory for his significant findings, including the co-discovery of mirror symmetry and the discovery of spatial topological change. He is the director of the Center for Theoretical Physics at Columbia University.

Universe Dark Energy:

• Astronomers believe that a mysterious, dark force is driving galaxies apart, causing the quicker expansion rate.
• Dark energy could be a property of space, according to one theory. Albert Einstein was the first to recognise that nothing is empty space.

Is there a cosmic acceleration:

• The universe is expanding, and each time it does, it grows a little quicker. The acceleration of this expansion is referred to by scientists as cosmic acceleration.
• The distance between points in the cosmos grows as a result of this expansion, just as stretching a rubber sheet causes the points on the sheet to move further apart.
