Question 1/4
According to the Big Bang theory, what happens if you reverse the galaxy motion and go back in time?
A. Everything would become condensed into one dense point
B. Some things would remain the same, while others go back
C. Everything would be the same as it is today.
D. You would find everything in a large cloud of cold isolated gas

According to the Big Bang theory, if you reverse the galaxy motion and go back in time A. Everything would become condensed into one dense point.

The Big Bang Theory simply explains how the universe was formed from a large explosion. According to the Big Bang theory, the universe was formed as a result of the explosion of particles.

The reverse of the Big Bang Theory simply means the scenario where the expansion of the universe reverses. This is also called the Big Crunch. This will lead to the recollapse of the universe.

In this case, the cosmic scale also reaches zero. Then, everything would become condensed into one dense point.
