Formation of Elements in the Universe Quiz

This theory states that all of the current and past matter in the Universe came into existence at the same time. Answer:

It is a debunked model/theory that the Earth is the center of the universe, with the sun and planets revolving around it. Answer:

A theory that planets were considered to have been formed as a result of a close approach to the Sun by some other stars. Answer:

The Big Bang Theory is the leading explanation for how the universe began. Simply put, it says the universe as we know it started with an infinitely hot and dense single point that inflated and stretched — first at unimaginable speeds, and then at a more measurable rate — over the next 13.7 billion years to the still-expanding cosmos that we know today.

It is an explosive expansion ballooning our universe outwards faster than the speed of light. This was a period of cosmic inflation that lasted mere fractions of a second — about $10^{-32}$ of a second, according to physicist Alan Guth’s 1980 theory that changed the way we think about the Big Bang forever.

Before Big Bang, there was a plausible hypothesis which states that the physical world was made up of a soup of short-lived elementary particles, including quarks, the building blocks of protons and neutrons. There was both matter and 'antimatter' in roughly equal quantities.

In the late 1940s, the astronomer George Gamow suggested that the initial explosion may have left some still observable traces. His reckoning was that a universe so hot and dense would have emitted a lot of light. With expansion, the characteristic temperature of this light would have.
