George Ellis - Are There Multiple Universes?

Multiple universes? The idea sounds astounding. Our universe is immense by itself. How could there be more than one? How can scientists come to believe in more than one universe?

I love George Ellis. He co-wrote a book years and years ago called On the Moral Nature of the Universe that was such an eye-opening work for me. He makes a very compelling case that the physical universe is anchored (or inter-locked, if you will) in an objective, abstract morality; Platonic, in a sense. It was a brilliant work.

Thanks to all scientists! Forever grateful.

This short doesn't capture Ellis' (perhaps the leading cosmologist alive), view on the possibility of a multiverse, but drifts off into speculation of closed space. What can easily be missed is that Ellis points to a consequentialist argument by physicists (Barrow and Tipler) to explain away the fine-tuning of the universe for life. He does say there is no evidence nor can there be for a multiverse. Further he holds such a strong view that the multiverse is not backed by evidence that at a conference in his home town of Johannesburg he supported William Lane Craig's presentation on the fine tuning points to a personal creator.

Carr said the multiverse theory is cosmology's dirty little secret (to resist a divine foot in the door).

The following quotes are taken from an article Ellis wrote entitled:

Editorial note to “Large number coincidences and the anthropic principle in cosmology”
George Ellis, University of Cape Town May 28, 2018

Finally, the physical existence or not of multiverse is basically untestable [25], but is an essential component in the explanatory use of the SAP; so it is not clear if this can truly be regarded as a scientific theory, rather than a philosophical principle. (p. 6)

Good science can stand up to scrutiny by itself, empirically. Bad science needs cheerleaders.

[jamesruscheinski]

Could fine tuning happen under Copernican principle, as life on earth is not the center of solar system or galaxy?

[jamesruscheinski]

Would quantum mechanics or time be able in principle to measure multiple universes, or at least outside universe?

[jamesruscheinski]

Would many universes be similar as many galaxies are similar?

[jamesruscheinski]

Is it possible that some day we could develop a way to learn beyond the universe that might be as good or even better than science and physics? Perhaps using information processing through computers and simulations will allow us to learn about things now beyond our reach.

[kenanderson]

Nothing travels faster than the speed of light may not be true everywhere. That is our current limitation.

[jamesruscheinski]

Does inflation exist outside and in between universes?

[jamesruscheinski]

With galaxies and universe flat, is there a way to measure or find what is above and below the universe, perhaps dark energy? Might even be small universes perpendicular to ours at the farthest reaches of universe.

[dougg]

Yep. Also The Marvel Universe. Multiple

[copyrightyourmusicareyousu]

billion's of Universes there are as most scientist now claim

[B.S...]

No Multiverse!!! ... SO WHAT!!! ... I'm not throwing out my text books and cracking open the Bible!
Is there a creator? Yea, he's the guy in the white lab coat!

These guys are just like religious leaders who have to lie in order to keep the jobs. They have no idea what the Voice of God is or how it produces life experiences for each created character.
