Q58

In astrophysics, what is the name of hole in outer space which emits stars and energy?

A.
Black Hole
B.
Ozone Hole
C.
Asteroid Belt
D.
White Hole
Answer

Answer: Option D

Solution

Answer: Option D
Solution:
In astrophysics, it is a hypothetical concept. In this theory white hole which is opposite to black hole emits stars and energy. In general relativity, a white hole is a hypothetical region of spacetime which cannot be entered from the outside, although matter and light can escape from it. In this sense, it is the reverse of a black hole, which can only be entered from the outside and from which matter and light cannot escape.
