Answer to Problem 10RAT

The correct option for the statement " Dark energy is thought to be found primarily within the" is option (b).

Explanation of Solution

The total energy of the universe is considered in the form of mass and radiation. To verify this theory, scientists carried out the result that shows the energy calculated through the total mass and radiation is less than the total energy. The scientists considered that the rest energy of the universe is present in the form of dark matter and dark energy. This dark energy is not visible.

The dark matter and known matter slow down the universe by the gravitational pull, but dark energy repels it. This is the reason that the universe is expanding with acceleration. Dark energy is thought to be found primarily within the deepest region of space where the matter is absent.

Conclusion:

Therefore, the correct option for the statement " Dark energy is thought to be found primarily within the" is option (b).
