A.
Black Hole
B.
Ozone Hole
C.
Asteroid Belt
D.
White Hole
AnswerAnswer: 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.
