The First Few Moments Of The Big Bang, What We Know And What We Don't Know
We are here to discuss the first few moments of the Big Bang. Let’s find out what we know about it and what we don’t know.
The newborn universe was very busy. Believe it or not, physicists take an attempt to understand the universe when it was only a few seconds old after the Big Bang.
At Least it can be said that the situation here was very complex during the Big Bang. But even as we make progress, there is still much that we do not know and we have a lot to learn from this. From tiny black holes to outside interactions, the universe was a very busy place.
The known knowns
Let's start with the General Framework, 13.77 billion years ago after the Big Bang, our universe was much hotter and smaller. Its heat intensity was such that its temperature was quadrillion degrees and in terms of size it was like a peach. According to the Astronomers Suspect, when our cosmos was brand new it ran a period of rapid expansion called inflation.
This inflationary event was the most transformative epoch in the history of our universe that once happened. In less than a blink of an eye, our universe suddenly becomes very large. And when this rapid expansion occurs, there is a lot of damage during the initial inflation, and a lot of matter is radiated in this universe and these are flooded.
In fact, the first elements appear a few minutes later. And speaking of this time it was very hot and there was a dance that made it hard enough to stabilize anything. It can be said that it was basically a giant mix of quarks and gluons. Which were basically carriers of the Atomic Nuclear and Straw Nuclear Forces.
Then when the age of the Universe is about 12 minutes, it expands and the quarks are cold enough to bind to each other. At the same time, the first protons and neutrons were invented. And these protons and neutrons first make hydrogen and helium and then some lithium. And then the first stars and galaxies were formed, except for one hundred million years.
The information from the first elements shows that after the Big Bang, the whole universe expands and cools. Then it becomes like plasma and then becomes neutral gas. We know that this broad-brush story is accurate and we also know that we are missing many details of it. We are basically talking about the antecedents of the first elements.
Some funky physics may have been in operation when the Universe was a few seconds old, and even beyond our current theoretical understanding, it could not deviate from our goal. We will know more about this.
Recently a paper is coming out which has been published in a preprint journal and it has been accepted for publication. It is the Open Journal of Astrophysics and through it, some scenarios of the previous Universe can be found and learned about.
There are still many questions about the Dark Matter thing. We do not know what the Dark Matter is made of, but we do know and understand that this Dark Matter is responsible for 80% of what happens in the Universe.
We understand very well how ordinary things in Early Cosmos turned into Hot and Dense soup. But we have no idea how this dark matter came to be. Did it originate within the first few seconds of the universe? Or did it come later?
Did it destroy the first elements of cosmic chemistry or did it just stay in the background?
We don't really know this.
Then it has its own inflation. We don't know what the power source provided for this incredible expansion event, nor do we know how long it lasted or when it ended. Maybe this inflation lasted longer than we thought.
It could also be that it happened before the second time we were thinking, or it was completed within a second. Another issue is that cosmologists have a massive thorn side called matter-antimatter asymmetry. We can learn more from experience that matter and antimatter are perfectly symmetrical. Among all the matter reactions that have occurred in this universe, there are corresponding particles of antimatter.
But when we look at the cosmos, we see that the hips and the hips of normal matter are not even a part of the antimatter. And in order to throw off these balances of the Universe, something big must have happened in a few seconds during extension, maybe something very big. But nothing is known about what it was or how it happened, and nothing is known about its exact mechanism.
If dark matter, inflation, and antimatter are not enough, it is very likely that the Early Universe probably manufactured a huge stockpile of black holes. And these were the only places where the density of matter could reach critical thresholds and these could trigger the formation of holes.
But with this Big Bang, the random patches of the Cosmos in the Exotic Early Universe may gain enough density, but they may also trigger creation without going into a black hole and be ready for a full star formation. However, it cannot be sure in any way, maybe the thing must be used.
Digging deeper: Big Bang
If you want to know about some of the moments of the Big Bang, you must do some research inside. And where our Big Bang theory is rich in data, there are many kinds of mysteries to increase the curiosity of the generation of cosmologists and to satisfy them. Another thing that can be said with great pleasure is that we have done a lot of research on this subject.
For example, we cannot directly see with our own eyes what happened in the first two seconds of the universe, but we can recreate the condition through powerful particle colliders. It may not be perfect, but it will help us to understand the environment.
We'll probably get some clues that happened in the first few seconds of the Big Bang. We can understand how the changes that occur in dark matter through lingering inflation affect the creation of hydrogen and helium.
And we will also learn how neutral gas was produced from plasma 380,000 years after the Big Bang. Maybe we have less technological capability due to which we will not be able to see the direct gravitational waves but we are moving much further in this regard day by day. And whenever we discuss or research extensively about this Big Bang, we can learn more about this Newborn Universe.
