What we do know is that the universe didn’t begin from nothing . It’s impossible for something to arise out of nothing, so there has always been something . Nothingness is the space that holds everything. From there it can be argued that the universe began with the adjacent possible of nothing.

Do we? Please enlighten …

It's not impossible for something to arise out of nothing. Well, what I really should say is, it's not impossible for two somethings to arise out of nothing, as long as they have opposite charge and annihilate when they come into contact.

I like to imagine there's an anti-universe moving backwards in time from the start of the universe, and that's where all the unexplained missing baryonic antimatter ended up.

"The issue is that physicists can’t accept the scientifically honest answer: We don’t know, and leave it at that." This sentence jumped out for me. Is there some kind of crusade going on that I have missed the beginning of? This feels like a strange sentence in this piece and feels like a (misguided) attack.

Early pixel blob analysis (I don't know a better way to put this, check Figure 5 in the paper) from the James Webb:

Suggests that the universe may be older than the Big Bang theory predicts. There are a lot of qualifiers on both sides of this, so I would suggest sitting back with some popcorn and enjoying the spectacle of a lot of primate descended life forms earnestly debating something that in many cases they couldn't even be bothered to read up on.

Got proof? ...and isn't that the whole point of the discussion?

Is there infinite?

Tough for finite things to try and understand much less comprehend such a simple and complex quandary.

What happens if there really is infinite no beginning and no end. Or what if there is an Alpha and Omega - such a beautiful thing to not understand.

Earlier quoted context omitted.

Sabine H. That’s her horse.

She's fantastic. She doesn't hesitate to call out the physics community on its idiosyncrasies. She is a necessary check and balance on the mainstream body of researchers.

I'm increasingly sceptical. She's not in research anymore but has found success running an "I know what I'm talking about" contrarian blog.

If she was a software developer we'd rightly start to wonder about grand pronouncements coming from someone no longer practicing in the field.

When your market doesn't exist if you actually agree with anyone, the incentives start to be questionable.
