What was the Big Bang?

Dear Readers,

I had to take the following passages from a book in order to make it easier for everyone to understand what is going on.

The book says that it is assumed that the universe was originally concentrated in a single point and only began to expand with the so-called big bang.

This is concluded from the fact that the universe is still expanding today, i. e. the distances between the galaxies are increasing. Consequently, there must have once been a starting point.

What was before the Big Bang?

According to the generally accepted theory, there was no "before the big bang", since time also only came into being with the big bang. And since it has only existed since the Big Bang, there can also be no "before".

Did the Universe once expand faster than Light?

According to current cosmological models, there was a phase shortly after the Big Bang in which the universe expanded very strongly in an unimaginably short time - and at a speed that was significantly greater than the speed of light.

Surprisingly, this does not contradict the law that nothing in space can move faster than light, since no matter was moved in the process, but space itself expanded.

Will the Universe expand forever?

Probably yes.

The latest theories say that the expansion of the universe - driven by "dark energy" - is even accelerating. However, to this day no one knows exactly what this dark energy is.

Scientists all over the world are feverishly searching for an explanation. The only thing that can be measured so far is its effect on the speed of the expansion of the universe.
