I was suggesting there was no Big Bang at all and the universe has simply always been; expanding eternally.
However now, a few posts later, it seems the inevitable total isolation is not a very palatable prospect. I don't want to go there so lets not make that true, okay?

Hmmm. Yes...
Is it impossible that:
The universe is expanding because there is "nothing" outside, like thin oil on top of water, and the void from where it's expanding from have such a vacuum that particles (both positive and negative) pop in and out of existence continuously, when the space consisting of intermittent particles is stretched the particles become permanent in random bursts, further strenghtening the process.
How's that for a "free thinker" Galu? 😀
I dare you to prove that this is more unlikely than the Big Bang 😀

Once upon a time, there was nothing, a nothing full of intermittent virtual particles popping in and out of existence continuously. Like noise on a pitch black canvas stretching for infinity.
At one point in time, two of these particles bumped into each other and because of this they solidified. This first solidifying of matter caused a reaction on the surrounding "noise", at random, other particles started filling the void, sometimes pushing, other times dragging. This caused an expansion of matter. After intitializing the expansion process and some increase in the existence of solid particles, the expansion triggered a vacuum. This vacuum had an increased rate of "noise" particles in a limited amount of space, further accellerating the increase of matter.
: There was never a "big bang" it is more of a "oil slick ooze" 😀

Could've been a Big Sneeze too, or a Big Fart. Or perhaps some other functions I won't elaborate on. 😎
You certainly have a way with words!
However, if you want my honest opinion, your words are all "noise" to me! 😀
Green Noise™
I see no proof that it's impossible! 😀
I hereby grab rights for "intellectual" property of The Big Ooze™ hypothesis.
Edit:
Pete can have 10%

Good for you Sabine!
The universe does not expand "into" anything and does not require space to exist "outside" it.

There is a transcript of Sabine Hossenfelder's video here:
Sabine Hossenfelder: Backreaction: What does the universe expand into? Do we expand with it?

A wild ride into Cosmology and Geometry. Took us a while to wrap our heads round it, IMO. 🙂
I now want to get a grip on the RATE of Expansion. Back of a beermat stuff at this stage.
This is our nearest neighbour Andromeda if you had a good camera:
Approximately a MegaParsec away. About 3.3 Billion kilometres I think. A Parsec being 3.3 light years. About the distance to our nearest stars.
What Is The Hubble Constant? | Space
Apparently the space between us and approaching Andromeda is expanding at an enormous 70km/s per MegaParsec.
Slightly slower on the distant objects, which are back in time. About 60km/s.
That's a lot. I am hoping to use hitherto neglected Matrix Mechanics to get a grip. But weirdness indeed. 1. The Geometry of Linear Equations - YouTube

Is there conclusive proof space is actually expanding? Or are we just pretty sure? Has it been proven that red shift is due to motion?
I wasn't totally convinced after all... "As we discussed, you can figure that out by making measurements on the surface of the sphere. You don’t need to say anything about the embedding space surrounding the sphere." Yeees but by just saying - ignore what is outside.... doesn't help me really.. 🙂
If she had said: Well, if you didn't get this, here is hwo to see it: There is only one entity - universe and it is expanding. Yes - one entity only and nothing more. Accept! But she is talking about two entities and that makes it problematic for me...
So I still don't get/accept it. Actually, I'm confused to the point that I cant sort out if I don't get it or don't accept it ;-D

In 1920s, cosmologist Edwin Hubble found that the more distant a galaxy, the faster it is moving away from us. This is Hubble’s law. This observational law is the proof that the Universe is expanding.
You are referring to the cosmological redshift which is not due to the relative motion of galaxies. The photons redshift because of the stretching of the local spacetime through which they are traveling.
