Big Bang

The Big Bang is the prevailing cosmological model that explains the origins of the universe. According to this theory, the universe began as an incredibly hot and dense state about 13.8 billion years ago and has been expanding and cooling ever since. 

The Big Bang theory explains the observed large scale structure of the universe, the cosmic microwave background radiation, and the relative abundances of light elements. It also predicts that the universe will continue to expand indefinitely. 

The Big Bang theory is supported by a large body of observational evidence from various scientific fields such as astronomy, cosmology, and particle physics.

Below is a timeline of the metric expansion of space, including the hypothetical, unobserved parts of the universe. On the left side of the timeline, the expansion is shown to be rapid during the inflationary epoch. In the center of the timeline, the expansion is depicted as accelerating (this is an artist's concept and not to scale).


After the big bang only hydrogen and helium along with trace amounts of lithium and beryllium were created. The other 86 elements found in nature were all created by nuclear reactions inside stars.

The Big Bang Theory, the scientific explanation for the origins of the universe, was first proposed by Georges Lemaître, a Catholic Priest who is widely considered to be one of the greatest scientists that many people have never heard of. On May 9, 1931, Lemaître published a letter in the journal Nature in which he proposed that the universe began as a single quantum, and that the concepts of space and time only came into existence after this original quantum had divided into many smaller quanta. He later referred to this idea as the "Primeval Atom" in a collection of essays. Lemaître's work served as the foundation for what would later be known as the Big Bang Theory, as other scientists built upon his ideas.

A small percentage of static on televisions is actually radioactive resonance from the Big Bang 13 billion years ago.

In 1964, Bell Labs built a large space antenna. Upon testing, two of their scientists encountered ‘interference’, which could not be isolated. After multiple attempts to fix the bug, they determined the “noise” was in fact, a remnant ‘hum’ from the Big Bang. They went on to win The Nobel Prize.
