Which of the following is/are cited by the scientists as evidence/evidences for the continued expansion of universe?
- Detection of microwaves in space
- Observation of redshift phenomenon in space
- Movement of asteroids in space
Select the correct answer using the code given below.
Correct Answer: Option A
The primary evidence for the continued expansion of the universe includes:
-
Detection of microwaves in space (Cosmic Microwave Background Radiation): This is considered the afterglow of the Big Bang and its existence supports the expansion theory.
-
Observation of redshift phenomenon in space: The redshift of distant galaxies indicates that they are moving away from us, implying the universe is expanding. This is a key piece of evidence supporting Hubble's Law.
-
Movement of asteroids in space: While asteroids do move, their movement is governed by gravitational forces within our solar system and is not a direct indicator of the universe's expansion.
Statement 1 is correct. Statement 2 is correct. Statement 3 is not correct.
Hence, option a is the correct answer.
