Frequently Asked Questions

What is the scientific definition of the Big Bang Theory?

The Big Bang Theory, or Big Bang for short, is a scientific model describing how the entire universe began with a giant blast of energy, which occurred about 14 billion years ago. Astronomers, or scientists who study space, say that at the moment of the Big Bang, space, energy, and all of the building blocks of life came into existence.

What evidence supports the Big Bang theory?

Several lines of evidence that strongly support the Big Bang model. One involves the relative abundance of the chemical elements that make up the stars and galaxies; the amount of hydrogen, helium, and heavier elements that we observe is just what the theory predicts.

What does the Big Bang Theory propose?

The basics of the theory are fairly simple. In short, the Big Bang hypothesis states that all of the current and past matter in the Universe came into existence at the same time, roughly 13.8 billion years ago. At this time, all matter was compacted into a very small ball with infinite density and intense heat called a Singularity.
