When it comes to the science regarding the true nature of our reality, you won't find a shortage of theories, or a shortage of criticisms of each theory.
We are like a race with amnesia, trying to discover and search for an answer that most probably exists, but has yet to be discovered. How did the universe begin? According to new research, there might not have been a big bang.
Instead, the universe might have existed forever.
The theory was derived from the mathematics of general relativity, and compliment Einstein's theory of general relativity.
The big bang theory postulates that everything in existence resulted from a single event that launched the creation of the entire universe and that everything in existence today was once part of a single infinitely dense point, also known as the "singularity."
Here is a good picture representing what the big bang theory is referring to.
So the big bang, again, postulates that the universe started out as an infinitely small point in space called a singularity, then exploded and created space where there was no space before, and that it is continually expanding.
One big question regarding that expansion is; how did it happen? As you can see in the picture, "who is that guy?!"
According to Nassim Haramein, the Director of Research for the Resonance Project,
This is one out of many criticisms regarding the big bang theory.
There are many considerations to be pondered. Can something come from nothing? What about quantum mechanics and the possibility that there is no moment of time at which the universe did not exist?
Again, so many considerations to be pondered.
According to Phys.org:
The theory also suggests (obviously) that there are no singularities or dark matter, and that the universe is filled with a "quantum fluid."
These scientists are suggesting that this quantum fluid is filled with gravitons.
According to Phys.org:
As you can see, when quantum mechanics is thrown into the equation things appear to be far different.
Again, this new theory is suggesting that the universe could have always existed, that it never was what we perceive to be as "the beginning." Perhaps it was just an event that did occur that we perceive as the beginning, perhaps the event occurred not from nothing, but something.
Again, who is that guy blowing on the balloon in the picture?
There is something there that has yet to be discovered.
What We Know Is Often Just Theory
To conclude, it's clear that we do not yet have a solid explanation regarding what happened during the Big Bang, or if it even happened at all.
This new theory is combining general relativity with quantum mechanics, and at the end of the day these are all just theories.
Not to mention the fact that theories regarding multiple dimensions, multiple universes and more have to be considered. When looking for the starting point of creation, our own universe might not even be the place to start. It might be hard given the fact that we cannot yet perceive other factors that have played a part in the make up of what we call reality.
What is even harder is the fact that quantum physics is showing that the true nature and make up of the universe is not a physical material thing!
We just don't know yet, and there are still new findings in modern day physics that delve into non-materialistic science that many mainstream materialistic scientists have yet to grasp and acknowledge.
I'll leave you with a quote that might give you something to think about:
