What Was Before the Big Bang?
My motivation for answering this question stems from a question I received on my old Q&A page. I plan to write about each question asked there, one by one, and then address it in more detail here over time. This way, I'll be answering questions people are curious about while still providing information. Of course, I'll also continue to write about whatever I feel like.
I just want to point out this: You're wondering what existed before the Big Bang, but do you know the moment of the Big Bang? Don't say you know, because no one in the world knows what happened. It's actually interesting to wonder about what happened before that moment.
The simplest answer to the question is: It's unknown what happened before the Big Bang. There are guesses. But while we can't even know the moment of the Big Bang, we have no way of answering the questions of whether there was anything before it, and if so, what was there? I'll explain it gradually... But please don't draw any conclusions from this or create new-age religions. :)
First of all, the beginning of our current universe is the Big Bang. Asking what existed before our universe is essentially meaningless. Why? The universe we know has a time dimension. Three spatial dimensions and one time dimension were created during the Big Bang. Therefore, there can be no time before the Big Bang. Therefore, asking about a time before it is illogical. Furthermore, if there is another structure or something we cannot fully understand, and since there is no time, that something would not be our universe, the question becomes meaningless and impossible to answer. Because our perceptions evolved according to three spatial dimensions and one time dimension, there would be no structure we could perceive even if we wanted to. However, with developing technology and mathematics in the future, we may have the opportunity to discover it indirectly.
Now let's move on to other options. The eternal inflation model. This is also the model that gave rise to the multiverse hypothesis. This model uses inflationary expansion, a hypothesis that inflationary expansion occurred just before the Big Bang, as a source. Inflationary expansion is the expansion of the universe from nanometers to 250 million light-years, occurring many billions of times per second just before the Big Bang. It is believed that the energy released when a field called the inflationary field falls from a high energy level to a low energy level caused this enormous expansion. It then loses its normal repulsive properties and forms the basis of the particles that formed after the Big Bang. In the eternal inflationary model, the inflationary field expands forever, and when energy is discharged in some regions of this field, the universe and universes are formed. Proceeding accordingly, there was an inflationary field before the Big Bang. And the question immediately arises: what existed before that? In fact, we can immediately understand that these questions are not scientific and constitute a paradox in themselves. It's like asking what the universe is expanding into.
Another hypothesis posits that the Big Bang resulted from the collision of the boundaries of two universes. It states that this signature is also present in the cosmic microwave background radiation. However, like the hypothesis above, this one is also quite difficult to prove. According to this hypothesis, we cannot say that anything preceded the Big Bang. This is because the energy condensed from the collision of universes in nothingness created the universe. However, we can speak of other universes in nothingness.
There's an interesting hypothesis. It says that the universe is the 3-dimensional event horizon of a 4-dimensional black hole. I've written about this before (A New Theory of How the Universe Came into Being) I wrote. According to this hypothesis, there was previously a 4-dimensional star that collapsed and turned into a black hole, and a universe in which it existed.
As you can see, there are many possibilities, but no definitive answer. Perhaps the Big Bang theory will even collapse. Who knows?
This article is a bit too subjective. It bothers me that you constantly treat people who come here seeking information as uninformed. We don't have definitive information about the formation of the universe anyway. However, we try to obtain information by developing theories and focusing on what makes sense. I find it amusing that you speak with such certainty about everything and dismiss everyone else as uninformed, when you don't even know that the formation of the universe can be explained by our laws of physics.
Hello, you are certainly free to express your opinions, and I respect this, but I must point out that I, everyone else, and even scientists are ignorant on this subject. We don't even know the moment of the Big Bang, and we only have ideas about both the moment and the time before it. We can't even create a mathematical formula. If we did, we would have resolved the difference between General Relativity and Quantum Physics. I'm not talking about a disrespectful ignorance here; I'm using ignorance as a descriptor, including myself and scientists. I don't understand what I'm certain about. I don't understand how or what I can be certain about when we talk about our ignorance so much. I'd appreciate it if you could explain this. The only thing I'm certain about is this:… Read more »
It's as natural to wonder about what came before as it is to assume everything came after the explosion. If nothing existed before the explosion, how could the elements of magnificent beings, not only on Earth but throughout the universe, astonishing objects and living things, come together? Everyone is aware that this is no coincidence. Such perfection cannot be the result of coincidence or the luck of the living being. There must have been something that brought it together. I don't think an explosion could have brought together all that perfection, and the formation of a being capable of thinking, not just a metabolism that eats, drinks, speaks, and breathes, could have happened. If it had happened as you say, we would have had many of the possibilities we now possess.… Read more »
Hello,
As I mentioned in the article, it's unknown. Hypotheses have been formulated scientifically, based on certain theories and using scientific methods and mathematical formulas, but they will remain hypotheses for a long time. First of all, I don't understand why you say "if only it were as you say." There's no judgment that this is the case. Everything you say is entirely your own reasoning. Of course, you can believe and express whatever you want, but I see neither respectful tone nor any informed basis in your article. I don't think you even read my article.
I hope you can understand what I wrote.
Before the explosion is as enigmatic as after
