Misconceptions About the Big Bang
Two things have happened because many channels (even those like the Discovery Channel abroad) distort science so that everyone can understand it. First, the Big Bang is seen as a real explosion. Second, the Big Bang is claimed to prove that the universe came from nothing.

Was the Big Bang really an explosion?
First, let's understand this: Just because the word "bang" appears in the name "Big Bang" doesn't mean there actually was an explosion. The Big Bang theory explains how the universe, once the size of a single particle, suddenly began to expand, creating time and evolving into the visible universe we know. The name "Big Bang" itself was coined purely as a joke, just like the Higgs boson is called the God particle.

Did the universe come into being from nothing with the Big Bang?

No. There is no scientific theory that claims such a thing. Big Bang As I mentioned in the first article, the theory describes how the universe, once the size of a single particle, suddenly began to expand, creating time and evolving into the visible universe we know. We don't know the moment of that expansion, or what preceded it, if any. In other words, it doesn't say it emerged from nothing and expanded. It describes the universe, confined to a particle-sized space, beginning to expand. There are traces of this in the microwave cosmic background radiation, which is a picture of the universe's earliest times. You can see them in the images to the left. Two theories have been proposed regarding these traces.
The first idea is this: There are three perspectives on the future of the universe. One of these is the Big Crunch. Gravitational force will eventually cause the universe to shrink again, returning it to its original size at the time of the Big Bang. Big Bang He suggests that it's possible that a universe previously experienced the Big Crunch, and that the universe is in an endless cycle of first expanding and then collapsing. However, it's understood that this will only repeat a certain number of times due to the constant increase in entropy.
Microwave cosmic background radiation. This shows traces of what are thought to be previous big bangs.
The second idea is based on the theory of multiple universes. It argues that our universe was formed by the collision of multiple universes, and that these traces are the result of these collisions.
At the same time, in a previous article I wrote (The Problem of Quantum Mechanics and Relativity Theory Not Being Compatible) I've written about why that moment and what came before it are unknown. However, there are many theories, such as string theory, that can explain them, and none of them claim the universe came into being from nothing.
In short, never settle for documentaries; always criticize, question, and explore beyond. Because there's always more.
Time has always existed at all times when matter or its building blocks existed. I want to slap those who write about this subject without knowledge. What do you call time, and how do you measure something as abstract as mathematics? Let me tell you how they measure time. Of course, they measure it with an atomic or electron clock, also known as an electron clock, which considers the movement of electrons around atoms as the origin of time. In other words, they measure it not by looking at how long it takes for the Earth to orbit the Sun, but by looking at the movement of electrons around atoms where we live. Here, we need to decide: If the Earth wants to complete its orbit around the Sun in 730 days, rather than 365, it would be enough for our vitality and senses.… Read more »
Good Gökhan, go and develop these ideas into a scientific theory and have them published in a journal. But please, no tabloid magazines. :)
Don't bother posting a link to the video of you reading the poem.
First of all, thank you for the first post of the year :) I'd like to return the expressions you threw at us by starting by saying that having fun on New Year's Eve and spending time with loved ones isn't egotistical, that people can always have fun, but that's not our topic. Regarding the explosion... We know that a singularity of infinite density and zero volume (what does this correspond to in our laws of physics? Nothingness? I'd appreciate it if you could shed some light on it. You mentioned particle size; is this definitive information?) suddenly began to expand for "some reason" (what is this reason? an effect, a force?) and many, many particles were dispersed from it in a scattering fashion. I know that the speed and balance of this scattering are important. Here, they express the effect of the effective forces in negative values of ten. This… Read more »
Thank you for your interest. I agree that everyone has the right to have fun, but seeing how unnecessary the expenses for fireworks and other things, even under the guise of New Year's celebrations, are, I can't help but criticize. It all depends on perspective. First of all, you've already stated what it is. A singularity is not nothingness. A black hole is also an example of a singularity (of course, it can't be the singularity at the time of the Big Bang, but it's similar). Black holes aren't said to be nonexistent. They swallow everything in their path. This could perhaps be more of a one-dimensional expression. With the beginning of the Big Bang, space-time also came into being. In other words, dimensions. And this moment can be explained by the one-dimensionality we call strings, which we call string theory.… Read more »
Thank you :)
