"The anthropic principle". Basically, the lifeforms question how strange it is that the universe is just right for them. Oblivious to the fact that in any other universe, they wouldn't be there to question it.
That said, the Physical laws of our universe seem extraordinary well-balanced. Strong or weak atomic force being just a tiny, tiny bit off in either direction and our whole basis of matter goes flying apart.

This is one of the most ******** answers I've ever read on this forum.

Well, it's not really "according to Elon" as he didn't come up with the theory. He's just a supporter of it (I presume) like many others. The maths supports the idea that everything we know could be an interference pattern from two sources overlapping. It's a fascinating idea which I personally like. I also favour the idea that one of the sources is stronger than the other which could account for the imbalance in positive and negative matter in our universe.

Everything is stacked in our favour and it’ s quite likely that, in my opinion, our particularly circumstances on earth are almost unique as well within the universe (or at least our galaxy) for intelligent life to evolve.
Even things like water ice floating on liquid water (one of the only compounds to do so) are necessary for us to exist.

Could an all powerful Creator set things up so that it looked like the Universe is exapanding but really isn't? Yes, given the limits of our current ability to measure it. Jus tlike an all powerful Creator could have planted fake dinosaur bones to convince palaeontologists that the world is older than 4,000BC. Do we operate on the principle that nothing we observe is known because maybe God is a poor humourist? No, we do not.
We observe the red-shifting of light. Ergo, the Universe is expanding in all directions for as far as we can sense. Which is a very great distance. Now if you believe that some cosmic entity is applying different standards to the parts of the universe we can't see and sniggering, well... you do you.

Well, at a given point in time, as well as Space. Go a bit further back and Earth didn't have water ice floating on liquid water. But Mars probably did. Go a bit further and Europa might (and possibly already does). The Universe is vast. It seems unlikely the right circumstances for life should appear only once.

unless you know absolute you cant state as fact. also anyone even 80 iq or below noes you never state fact in a internet arguement/debate. its bait topic the fishing real is going.....

The universe isn’t really just right. There are pockets of it which contain matter, but the enormous majority of the universe is composed of nothing. There are miniscule parts which contain anything at all, and of those parts that contain something, the chance of life existing is even smaller.
I think there’s a slightly different perspective to be had here. We might be in the millionth iteration of the universe as we know it, for all we know, and any number of those could have been more of less successful than the one that we exist in now.

The Universe does seem just right, though. Look at the strengths of the different fundamental forces. If we filled the universe with a bit more matter it would never have expanded the way it did. If the Strong or Weak atomic forces were just a tiny bit different to what they were, matter would fly apart, if the proportion of anti-matter were just a bit closer to parity with matter, we'd be blasted to bits by the explosive energy of particles annihilating themselves. There are a hundred ways in which the Universe is "just right". Whether that's through a million iterations as you say, something we can't yet understand or simply us misunderstanding Physics and ruling out a lot of possibilities as something that couldn't work when it could, we don't know. But there's definitely a Baby Bear thing going on with the Universe which is just extraordinary, imo.
No, this has been dropped now, the theory was banded about in the 80's but there's no sign of the universe contracting. Most likely the universe will expend until it burns itself out
What?
You obviously don't read your own posts then. Your incoherent garbage rambling did not even mention dark energy.
Sorry, maybe that was a bit rude.... its "Christmas" after all.

We know it as absolutely as we really can know anything in science, your philosophical position can be summed up as "there are no facts".
"Expanding into what?" just shows your lack of understanding of what metric expansion actually is. And your position again is basically summed up as "there are no facts".
No, we can see that the rate of expansion is increasing, currently measured to be around 73Kms/Mpc.

The number 42 is the answer to the ultimate question of life,the universe and everything.

We wouldn't be here to think that if it wasn't just right, though.
Any species with our level of intelligence existing in any universe is going to think that.

It's expanding at an ever increasing rate of expansion.
Postulated to be caused by so called dark energy.

The Earth with its stable climate and stable orbit and stable star over hundreds of millions of years may be one of the strangest things in the universe.

Its true though. No facts all we have is theories with some supporting observations. You believe they are facts and youre no different to those who believe in God or whatever.
We dont understand how the fundamental forces are transmitted.
We dont understand what additional dimensions may be beyond the ones we can perceive or observe.
And numerous other fundamental questions.
Ive no issue with presentation of theories but no one can use the word fact unless its proven beyond all doubt and that includes what the underlying mechanics of it are.
If the universe is expanding then great, what is causing it and what is beyond?

I don't know...the circumstances that make Earth habitable for life as we know it are a ludicrously implausible long chain of unlikely events. I think we don't know enough to assign any meaningful degree of probability to how often that occurs. Also, "It's life, Jim, but not as we know it" might turn out to be truthful. We don't really know for sure what is absolutely required for life, so maybe some signficantly different forms of life exist in a variety of circumstances. There's a bit of evidence that way in the form of extremophilic life on Earth, which thrives in very different circumstances.
The observations are facts. So yes, we have facts. Redshifting is a fact, for example.
Why assume there is anything beyond the universe?
