It summarizes from 9.42 on wards for a minute and a half. It talks about truly large numbers and possibilities. For example given enough time it's possible that all air molecules in a room will find them themselves at the same place in the room momentarily. By extension it also states that all the particles in an observable universe could find themselves at the same spot recreating the conditions of the big bang given enough time.
He talks of the potential for this to be a relatively "localized" event in an infinite space so overall not much changes in the "greater" universe. For example if our observable universe started collapsing and recreated the conditions of "our" big bang and recreated "our" big bang, an observer 300 billion lights years away would be unaware of this ever occurring.
If this process repeats itself at random places in the universe, it could mean that "big bangs" happen relatively frequently given infinite time, it's just we would never be aware of them. It would also point to in infinite past as well as the infinite future.
I have tried to summarize but it's best to spend that minute and a half watching the summary to get a better idea.
I am familiar of the dangers of "pop-sci" video's trying to teach science and the dangers and gross misrepresentations this can present. Personally I do not find the findings of the video reasonable as the matter would be so spread out so much due to cosmic expansion but his use of "Laws of truly large numbers" and "infinity" with which I am not overly familiar with prompted me to create this post asking for feedback from those more versed in these topics. i.e the members of this forum.
Thank you in advance for your comments.
