Which of the following points could be raised when presenting arguments against the big bang theory? a. it is just an educated guess. b. there is no supporting experimental data. c. it does not explain the clustering of stars. d. it can be changed at a later date.

We've all heard of the Big Bang theory (I'm talking about the cosmological model, not the TV show), but it's important to understand what that theory is and what it's not. Let me take this opportunity to be precisely, abundantly, emphatically, ridiculously, fantastically clear: The Big Bang theory is not a theory of the creation of the universe. Full stop. Done. Call it. Burn that sentence into your brain. Say it before you go to sleep, and first thing when you wake up.

C) It does not explain the clustering of stars.

Explanation:

Big bang theory explains why stars are moving away from each other in the galaxy and even one galaxy is moving away from other galaxy just like fragments fly away from each other after any small explosion. The theory is yet to be proved by experimental data. But there are some observation which does not conform to this theory. We all know that stars are found in groups in the universe. They are called galaxy. If stars are moving away from each other how come they form groups. So clustering of star is not possible as per this theory.

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
