Q. Consider the following statements regarding the Hoyle-Narlikar theory:
1.Unlike the Big Bang theory that suggests a definite beginning of the universe, this theory maintains that the universe has always been there without a beginning or an end.
2.It acknowledged the expanding nature of the universe.
Which of the statements given above is/are correct?
Answer: C
Notes:
Explanation: Both Statements are correct
Statement 1 is correct: ‘Steady State’ Theory of the Universe was jointly proposed by Jayant Narlikar and Sir Fred Hoyle, so also known as the Hoyle-Narlikar theory. This theory maintains that the universe has always been, and would continue to be, the way it is — infinite in extent, without a beginning or an end. Unlike the Big Bang theory that suggests a definite beginning, and possibly an end, to the universe.
Statement 2 is correct: It acknowledged an expanding universe, which was experimentally verifiable, but proposed that the universe was able to maintain a constant density by continuously creating new matter.
