Fluctuation Theorem, Big Bang Question

AI Thread Summary
The discussion centers on the fluctuation theorem and its implications for the early universe. It suggests that in a very small area, entropy could decrease more frequently, potentially leading to a decrease in the conventional understanding of time. The concept of quantum fluctuations is proposed as a factor that could disrupt the balance of entropy changes, influencing the flow of time. Additionally, many models indicate that time and spatial dimensions emerged from the Big Bang, prior to the formation of matter and energy. This exploration raises intriguing questions about the nature of time and entropy in the context of the universe's origins.

I have a question. I decided not to put it in the "theory" section because I'm no physicist and I don't know if I'm right.

From what I understand about the fluctuation theorem, the smaller the area in which it takes place, the more likely entropy is to decrease. Could it be at the beginning of the universe, when everything was very very small, that entropy decreased as often as it increased? Would this get rid of the notion of time? Could quantum fluctuations throw off this balance between decrease and increase, which would lead to the forward flow of time and the universe as we know it?

I hope these aren't too many questions.

Thanks,
Lucretius

If you posit a BB singularity, time did not initially exist. So in that sense your question is on target. Many models predict that time and spatial dimensions emerged from the BB - even before matter and energy. What happens after that is more interesting.
 
TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'
This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...
