Tryng to find out if the big bang is true. Seeing if it is possible to find enough informatation/
Method
Researching on certfied and real websites.

Mylour question
What evidence is there to prove the big bang theory?
What is the big bang theory
In simple terms the big bang theory is how many astronomers explain how the universe began. About estimated 14 billion years ago a hot and dense tiny dot became our universe today. It’s a theory of how the universe is still expanding and at the beginning of it, it was a tiny cluster that exploded
Who started it?
The big bang theory was originally thought of by astronomer Georges Lemaître in 1927. Later reinforced by Edwin Hubble 2 years later in 1929. The thoery, was built over many years.
Why did they think it?/what proof is there?
In 1929 Edwin discovered that other galaxies were moving away from ours, the further the faster which made a lot of sense. Expanding on the theory of the universe expanding. This reinforced what Georges Lemaître said. This is the concrete and main evidence of the theory but there is some
What contradicts the big bang?
Another theory, early rival to the big bang theory in the mid 20th century, is the steady state theory. The steady state is about how matter is constantly filling the gaps from the universe's expansion keeping its overall structure, connecting to the discovery of the big bang theory. According to Nasa the steady state would have no begining or end.
Why don’t some people believe it?/ Evidence against it.
People have all sorts of opinions, many believe it is true, many don’t. In recent studies by Lpp Fusion it was discovered that there are rotations in filaments of galaxies, which would have taken trillions of years, but the Big Bang happened 14 billion years ago and since it was the beginning of the universe, it may not be true. There is also a prediction that there would be some type of dark matter needed for the Big Bang to have happened, but it was observed that there was none found. They also observed that there would be a little lithium and a lot of helium if the Big Bang Theory happened. Instead astronomers discovered that in older stars there is less and less.

Data
(Same as research)
Conclusion
With all this information, I found that there is evidence against, but also to “prove” The big bang. There are many possible ways or how the universe began and there is no set answer. But there is many theories on how it began, or if it has always existed. But I think that some of it is true, and maybe even all, but after all I learned there are many possibilities.
