Universe fine tuned?

[NotAllThere]

Fred Hoyle reckoned life originated off-earth.

I highlighted your statement "It’s healthy to keep an open mind." anyone else would have realised that I was referring to that particular statement in my question.

Btw #1, what makes you think that the "Human" race isn't just another species that will eventually become extinct?

And Btw #2, you're wrong!

And there are many humans with very low intelligence indeed…

From the original wiki link:-

"One hypothesis is that the Universe may have been designed by extra-universal aliens. Some believe this would solve the problem of how a designer or design team capable of fine-tuning the Universe could come to exist. Cosmologist Alan Guth believes humans will in time be able to generate new universes. By implication previous intelligent entities may have generated our Universe.[29] This idea leads to the possibility that the extraterrestrial designer/designers are themselves the product of an evolutionary process in their own universe, which must therefore itself be able to sustain life"

As in Pocket Universes? (Okay so I can use Google).

Not sure myself, it sounds like a nice idea but it does seem like the sort of thing that someone comes up with to help shore up a pet theory. Trouble is, it makes things more complex, if we are in a pocket universe, then 'outside' there must be another universe. But is that another pocket universe and what's outside that, and that and so on? You end up with the possibility of an infinite series of universes each of which can contain an infinite number of universes with an infinite number of 'gods' that have created them. If it isn't infinite, then there must be a 'mother universe' that seeded all these other universes, how did that come into existence?

I'm sorry, it's a nice idea but I don't buy it. To me, a decent theory of the universe should be simple (in relative terms) and shouldn't rely on invented propositions to explain it.
Me, the one I like is one I heard many years ago that states that the the universe came into being due to a quantum fluctuation in the space time continuum (the Big Bang). The universe will expand for a bit, then fall back in on itself resulting in a Big Crunch. The universe can exist as everything that came into existence during the Big Bang disappears back into the space-time continuum at the end, the net effect is zero and everything balances out.

I read a science fiction book of his a long time ago. Can't remember the title or what it was about but I seem to remember that he used it to blather on about his steady state theory of the univers.

BSc (Hons)? ****! I'm impressed.

Sounds most likely. But what caused this 'quantum fluctuation', and why doesn't it happen more often?

The steady state theory was more appealing to atheists (such as Hoyle), because it did without the requirement for a first cause.

Just Googled that. Fascinating that he found the idea of the universe having a beginning as pseudoscience, but then went on to propose some C-field thingy to continuously create matter.

Buggered if I know. I did quantum physics in college but that was a long time ago and all I remember about it was the book was blue, very big, very expensive and I had to buy a second copy when I left mine on the bloody train.
