A Mirror Image of Our Universe May Have Existed Before the Big Bang
Like a mountain looming over a calm lake, it seems the universe may once have had a perfect mirror image. That’s the conclusion a team of Canadian scientists reached after extrapolating the laws of the universe both before and after the Big Bang.more…
Yeah nah.

Someone needed to write a paper urgently.

Haven’t read the link, but it seems a reasonable, if not particularly original hypothesis.

It may be simpler than various other ideas but it’s just as if not more speculative.
What happens to thermodynamics laws if everything’s going backwards?
Hawking and Penrose ruled that out for a contracting universe.

Depends what you mean by “everything going backwards”.
But any hypothesis about “pre” “Big Bang” is pure speculation, so I don’t see how any hypothesis can be more or less speculative than another.

Read the article, they accuse other cosmologists of “making stuff up”.

OK, but they all do that. Both the making up and accusing others of it.
But any article that includes the Universe starting as an infinitely dense point of zero volume as an indisputable fact gets my down vote, so I’ll agree with the nah.
The “eternal inflation” multiverse makes the most sense to me at the moment.

The universe is metastable, that’s a fact. So it makes sense that the universe as we know it began as an an instability in a previous universe. This avoids the problem of infinite density and temperature while at the same time allowing the evolution required to produce the fine tuning of physical constants that we see today.

Or this universe is one of the stable universes out a large number of failed universes
This are more thought experiments or philosophies than theories, you fit the universe conditions with the maths you create first

The tools we use to look at the universe are insufficient, we look at things linearly, space distance time etc.
We need a new processing paradigm that breaks the shackles of our formative hardwired line of thinking.
Even trying to imagine a new paradigm is limited because in our imaginings we use the same old tool and processes. Maybe our destiny is to seek but never ever reach the end game.

You should stop talking about yourself that way, PWM…

That’s a startlingly good point.
What are those tools?
Is that all?
I used the “what if?” tool for studying infinity, because analysis, analogy, logic and observation wouldn’t work on their own.
