The prospect of irregular and unpredictable physics gives me anxiety
With the universe is not being locally real, and now this... Oh man. Exciting times for sure.
Yes, discovery is awesome, and this is some crazy shit— it’s just that I prefer that the the rules that govern time and space make sense, lol.
It makes sense — we just don’t understand it yet 😀
Fine
It's turtles all the way down.
I predict bubbles warping time but not space, thus distorting the apparent speeds of objects we see through them. Star Trek taught me that anything is possible. 😆
And just imagine the new fields of math such a discovery would create...
“I’m just going to round it anyways” - Engineering
The Intel floating-point math error strikes again.

What do you mean by this?

eli5 this universe not real thing. i can never wrap my head around it.
It's as real as anything gets. What constitutes as "real" is more of a philosophy questions than physics question. Make up your own answer.
This article https://nautil.us/chaos-makes-the-multiverse-unnecessary-236664/ made me very uncomfortable back when it was published. It takes what you say to the philosophical limit.
Uh, I hate how that article says 'she' for a scientist (just as I would hate if it said 'he'). Say 'they'!
Neat
As a science bitch I’ve never believed in the Big Bang… I think everything has always been and will always be and it goes on forever in every direction and when I think about that my feet feel weird
Do you have evidence to support your position? Or is this just wishful thinking?

If I remember correctly, that's basically the Einstein - de Sitter universe, one of the early cosmological models. Einstein also didn't like the accelerated growth of the universe, he called the cosmological constant (what's now known as dark energy) a big mistake.
So when you run that model backwards a few billion years in your head then what do you think that looked like? I don't follow what you mean.
The best moments in science are when we say, “wait, this doesn’t work.”
The sound of scientific discovery is less often "Eureka!" than "Huh, that's funny..."
That's exactly the opposite of how religion works and the reason why I firmly believe that there should be a clear separation between state and church.
People can believe in whatever delusions they want as long as they don't force them on me.
But they always do, always, everywhere.
Even France which prides itself on it's secularism is getting pounded. The US is delusional, "In God We Trust" ? Really, fuck that guy...
If you have church, it's always church and state.
Wouldn't that just be forcing your view of separation of church and state on everyone else?

I just want our universe to be cyclic, heat death is depressing
Even though I won't be there for it, somehow heat death makes me very sad.
Big bang happened once, why not twice?
Well, you can't unmix paint. Entropy unfortunately only goes in one direction.
I feel the same. Even if myself, my kids, earth, even the human race as we know it won't be there anymore, it's kind of sad. Slow inevitable doom. Carpe diem I guess.

On a cosmic scale, I find it kind of comforting that everything is eventually going to be gone. It makes it more important to enjoy one's time in the now.
The problem with this idea is that everything was already gone before the universe started, and here we are.

Considering we don’t understand dark energy and dark matter. I hold hope that there are other possibilities.
However, all hail the god of entropy. The one thing that dictates and impacts every moment of our existence
If it makes you feel better, if ideas about multiple universes end up being real, it's possible a sufficiently advanced species might be able to "hop" universes and escape heat death that way

This was kind of the whole point of the JWST so it's a good thing!
Damn, the beings running the ancestor sinulation must have downloaded a new patch.
Should have sent it to QA, instead of making the devs do their own.
I actually had no idea that an irregularly expanding universe was the conflicting theory.
From my armchair astrophysicist perspective, I just assumed it couldn't be a perfect sphere due to the background radiation map.
Obviously scientific method and all, but this is super cool that for realisies it might change some minds.

I guess going by CMB radiation isn't that reliable, since the speed of light is a constant, but we don't know squat about dark energy
plus, something as big as the universe, gotta make allowances for the butterfly effect

Is it because our universe is actually some type of organism and it has growth in different areas more than others?
The summary is misleading. We have two ways of calculating expansion that, according to our current understanding, should arrive at the same answer, but they're off by about 10%. It's more a question of how we look than where.
Edit: corrected "title" to "summary"
