Question

Why is the abundance of Helium in the universe evidence for the Big Bang?

Helium requires high temperatures and pressures to form, so all of the helium in the universe must have been created during the Big Bang.

All stars in the universe burn helium, so it must have been created in the Big Bang.

There is too much helium in the universe to have been formed just by stars alone, suggesting that the early universe was as hot and dense as a star.

Helium is only made in supernovae explosions, so the early universe must have exploded like a supernovae.

Explanation / Answer

ANSWER:

Helium is only made in supernovae explosions, so the early universe must have exploded like a supernovae.

Universe makes almost nothing for one simple reason: if it was hot-and-dense enough to fuse elements together in the very early stages, it was also hot enough to blast those composite elements apart again.

Helium is only made in supernovae explosions, so the early universe must have exploded like a supernovae.
