Answer to Problem 1QAP

The statement is True.

Explanation of Solution

Cosmological constant is the term related to dark energy; it was given by Einstein in its theory of relativity. Einstein first assumed that universe is constant and it does not vary with the time.

However, after Hubble’s theory of expansion, the theory changed; Hubble theory explains that universe is expanding in nature. Space can have non-zero energy even there is no matter.

This empty space energy named as dark energy creates the repulsive force that can expand the universe. Cosmological constant is an example of dark energy.

It means cosmological constant always acts against the gravity that accelerates the expansion of universe.

Conclusion:

The cosmological constant explains the acceleration in expansion of universe. Thus, the statement is true.
