Here's What We Know About the Big Bang and the Universe's Expansion

WRITTEN BY: Anthony Bouchard

One of the most widely accepted notions regarding the formation of the universe is the Big Bang theory. In a nutshell, it’s a concept in which all of existence was once crammed into an area of space that was nearly identical to zero, and perhaps unsurprisingly, it exploded, resulting in the massive ‘bang’ that this theory gets its name from.

Upon exploding, all that mass and matter began expanding outwards, forming atoms, stars, and galaxies in the process. Some of that matter went on to form planets, and more of the matter went on to form the massive gas and dust clouds in space. All the while, the universe kept expanding.

But where did the Big Bang originate, you ask? Well, that’s a challenging question to answer, especially since all of existence isn’t necessarily drifting away from one particular point in the center of space, but rather things are drifting away from everything else around it and being influenced by gravity all the while.

Another thing to consider is the fact that the universe is expanding faster than the speed of light, and this means that light emitted from anything beyond what’s known as the ‘observable universe’ can never reach us. Stuff within this ‘observable universe’ is so far away that the light we can see resembles what those objects looked like billions of years ago, rather than today.

The universe is a particularly strange place, and astrophysicists are continuously trying to make sense of it all. While questions such as ‘where did the Big Bang theory originate?’ might pop up from time to time, there’s no telling if a factual answer will ever materialize.
