If the universe is curved dark energy is still a problem because the expansion is getting faster and overcomes the current curvature bounds.

#32This has been one of my pet theories for a while. https://news.ycombinator.com/item?id=39271752
I love that theory. I very much spent time thinking that it would be cool if we were inside a black hold after reading A Brief History of Time.

"Your honor, I could not have possibly shot that person, because yesterday might not have been before today, or at least, there is reasonable doubt that yesterday was before today, according to some physicists on crack. I treat those physicists with high regard personally though, and they have degrees that you don't have, so the court must reasonably conclude their opinions should be entertained."
I guess that's a joke, but it's actually kind of serious that causality, personhood, identity, free will, etc. are all social constructs. They are useful to us, but every now and then it's helpful and humbling to remember it's a fiction we assign, rather than fundamental. Criminal justice or the concept of culpability is one of these areas. I know I've seen material by Robert Sapolsky, a neuroscientist who does not b…
You’re stating this as if determinism has been proven beyond a doubt which is not the case.

There is no proof of "nothing " existing. Every observation we take, we see "something".
Than why do we need a beginning if there was always something.
For the same reason the mind seeks for an ending if there is something. It’s the environment our little neural nets trained in.

#35"Nothing" implies that something exists, this duality creates the universe.
That’s a boring axiom.

We don't. There was never nothing, because there is no "before" the big bang. Time as we know it did not exist until the big bang. It's not there was nothing, it's that there was no there or then.

#38Isn't time a human invention useful to model the nature? It's literally just a defined interaction as a reference, i.e. the sun rising up and going down which is the rotation of the earth. So IRL there's no time, there's no need to have a beginning or an end. Whatever happened when all the matter was close together isn't the beginning of anything, just a phase.
No, time is what the clock measures. Consciousness does not collapse the wave function meaning clocks exists without humans and time exists without humans.

"Objection, your honor. In the many-worlds interpretation there is a world in which that happened."
I wonder how far counsel could
take it before the judge hit them with contempt for lawyering while Nietzsche.

We don't need it, the same way we don't "need" scientific proof about anything. We could live our whole life pleasing the stakeholders and be happy about it
