I am aware that there are indeed competing cosmologies. But none that negates a continuously occurring energy at the fundamental level.

You mean there are no cosmologies that have a constant, energy = 0 content. Well whoop de fucking doo!

Energy being reduced to 0 within the system explains observation; it does not explain how energy that is incapable of being created came to be associated with the system.

The universe from nothing does indeed explain the big bang. However the energy source always existed in some form.

Which observation shows energy being reduced to 0? This is not a feature of the observed accelerating universal expansion, as you have already been shown.

What energy is incapable of being created? You have already been shown how this is not true.

The universe from nothing does indeed explain the big bang.

How?
However the energy source always existed in some form.

Then that model cannot be creation ex nihilo.

You insist to use terms incorrectly but claim knowledge about truth. How does that work?

Perhaps he needs to consider brane theory to resolve his self induced conundrum ...perhaps a refresher tour.

Answer me this question: has energy always being a function in existence? or does the evidence suggests that energy was created with the big bang? All of your wriggling and writhing reduces to an answer of this question.

Which model are you trying to discuss? Creation ex nihilo in a single event or one of the cyclic models and if so, which?

All of your wriggling and writhing reduces to an answer of this question.

For what reason did you not answer my questions?

You can use any model you like to explain energy that had no prior function to the universe's inception.

My reasons for not answering your questions is that my description which reconciles infinity with the finite universe is not a mathematical model, and one that I never divulge in public.

Since you have divulged your model in public and it contains a contradiction, there's nothing left to discuss. The models in the OP on another hand...

Coming up at the bottom of the hour on the PBS space time youtube channel

Theory of Everything Controversies!

Join Matt O'Dowd, Brian Keating, Lee Smolin, Lisa Randall, Sabine Hossenfelder, and Eric Weinstein as they grapple with the search for a Theory of Everything. Where should we be looking? Is progress hopelessly stalled? Will the next step forward come from outside the academic community? It's going to be awesome!

Watch on youtube only...

https://www.youtube.com/watch?v=_izocEgArtQ

Hmmm... some technical hitch that I'm sure will sort itself out soon...

Here's their youtube channel link for now... https://www.youtube.com/c/pbsspacetime/videos

Looks like someone took a wrong turn at the Big Bang! Drumming fingers...

With hindsight, this may be improved by future editing. My apologies if I've wasted time... Heigh ho.

Alan Guth and Sir Roger Penrose in discussion about competing cosmologies for an hour and a half. Moderated by Phil Halper, it's a fine way to pass an evening or few...

Alan Guth seems to have taken on Sean Carroll's ideas about a double-headed arrow of time in this latest incarnation.

I happened to watch Carroll’s “debate” with WLC from 2014 where Craig cherry picked and misunderstood Guth and Penrose quoting them and “religosplaining” them to Carroll. WLC then retreated into incredulity as that was all he had left.

How was I today years old before I learned of Penrose's Nobel?
