The Big Bang Theory is the leading exploration on how the world was created and how it is expanding.

The big bang theory is just one of the theories of how the universe was created,most and is the most popular out all of them .
One of the other believes is that god created everything and nothing else could have made it .

The idea of the big bang theory was made in the early 1920 by a guy named Georges Lemaitre . When he thought that the universe was made by a single primordial atom . Edwin Hubble also supported his idea because it went along with his observations that the galaxies were moving away due to something. There is also many other thing they have discovered that will also support the big bang idea . For example space and time seem to be expanding in all directions due to an explosion and also leading to conclude that there was a focal point for expansion .

““Three main observational results over the past century led astronomers to become certain that the universe began with the big bang.”( Yuki D. Takahashi ) One of the reasons was that the universe is expanding , since the universe is expanding they think that it first had to have been together for it to expand unless a explosion happened . 2nd it is that the big bang perfectly explains why there so much ambulance .

According to the big bang theory the world emerged 13.8 billion years ago at a single moment in a huge explosion. Most of what we know is because of mathematical theory and models.Scientes can still see the explosion through what is called the cosmic microwave it is also known as the afterglow.

There are things called “singularity”( NASA ) these things are zones that defy our current understanding of physics. It is thought to exist in the middle of...

...ow it was in the past . This is because light takes a long time to cover large amount of spaces . For example one of the closest star is Proxima Centauri which is 4 light years away , this means that you see it how it was 4 light years ago.

There is still many unanswered questions due to the big bang theory , but there is still many thing to discover and every day we are learning something new about our universe .

Definitions:

Supernova : “a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.”( Google )

COBE : is a satellite that was sent precisely for cosmology, sometimes referred to as Explorer 66.”The Cosmic Background Explorer”( Google )

Dark Energy : is a repulsive force that counteracts gravity and causes the universe to expand at a faster rate .
