The big bang theory states that all the matter that makes the universe was, at the beginning,
I in a single infinitesimally small and infinitesimally dense point. Then, the
point explodes given birth to the universe that we know. One of the major foundations
that the universe was originated in that explosion called the big bang was made
by Hubble when he proved that the universe is expanding; therefore, generally
speaking galaxies are moving away from earth. The occurrence that contradicts
the big bang theory is: A “Over time, distant galaxies move progressively closer to Earth 

The correct option is A. Over time, distant galaxies move progressively closer to Earth that occurrence would contradict the big bang theory.

A galaxy appears to be regressing more quickly the further away it is because space is expanding. The nuclear fusion events involving these elements produce the energy used by stars. Regarding the stars' blue-shifting, there is no evidence to support the big-bang idea.

What is the motion of distant galaxies?

It appears that farther away galaxies are moving more quickly than nearby ones. The wavelength expands and is redshifted towards the infrared side of the electromagnetic spectrum as these galaxies move away from us. A galaxy that emits predominantly visible light will therefore appear infrared when it reaches Earth.

Here is a list of some of the big bang theory's most frequent detractors: It goes against the first law of thermodynamics, which states that neither matter nor energy can be created nor destroyed. The big bang theory is criticized for implying that the universe was created from nothing.
