Suppose the extreme case occurs where all countries outside the U.S. decide to rapidly move away from using the U.S. dollar as a reserve currency. Also, suppose that investors outside the U.S. wanted to sell their U.S. Treasury bills and bonds as soon as they mature and not buy new ones. Would there be any way to avoid a catastrophe in the U.S.? Alan Greenspan famously said that the U.S. can always pay its debt by printing money. Given the massive size of the debt (> 40 trillion), is it likely that a fire sale on U.S. treasuries, coupled with an end to the U.S. reserve currency, would cause hyperinflation in the U.S.?

Under the Oscillating Universe Theory, the universe expands from a Big Bang, ultimately to collapse into a Big Crunch and then trigger another cycle. Before a Big Crunch occurs, would entropy begin to decrease? What happens to time? Finally, what will happen to the weak force?

I'm a mathematician. Most of my publications are in pure maths. Once in a while, I collaborate with a scientist who is not a mathematician by trade. Now that AI is in the picture, a collaborator is sporadicly asking AI questions and then sending the output to me. We have co-authored one paper and submitted it for publication without the use of any AI. There are a couple lingering questions, one difficult and one that appears solvable. I sketched out how to solve the easier one. A couple of weeks go by, and now he sent the output of an AI assistant on the easier problem. The AI claims to have a partial solution, but I don't want to look at it, since I'm pretty sure I already have a solution. Does anyone here find themselves in a similar situation? I don't want to cite AI on a problem that I can solve myself and just need a little time to write up the proof. Should using AI on research be considered similar to asking a human colleague questions? Even in the case of humans, I prefer that my collaborators don't run to someone else in their department and ask them a question that I already sketched how to solve. What do you think?

I just finished reading The Animate and the Inanimate by William James Sidis. Are there recent critiques of his theories (which he himself calls speculative)? I do not believe Sidis to be a quack. He entered Harvard at the age of 11 and graduated at 16. He was later labeled a failed prodigy and decided to live as a recluse, working menial jobs. Unbeknownst to the vast majority of people (including scientists), he continued to study and publish in his spare time, mostly under various pseudonyms. Is anyone here aware of rigorous scientific developments that would refute or support some of his theories speculated in The Animate and the Inanimate? In particular, Sidis describes the beginning of our universe as the "Great Explosion", which he published in 1925, two years prior to Lemaître proposing what is now called the big bang theory.
