In the past they have gained info by studying people who have survived brain damage due to an accident etc. Rather extreme damage in some cases. 😉 Past interest, Info probably around.
There is also a relatively new kid on the block

On can’t help wondering how hallucinations are stored in the brain 🧠 and if they can be retrieved. Probably not, otherwise there would be people having LSD flashbacks all over the place. Or maybe they are. Difficult to say with certainty. 😦
Penrose is no doubt a brilliant man but I find his ideas wacky-doo.
Good enough for a Nobel Prize though.

Yes I suppose. Not my order of the "creation process" above in #3004 - isn't that what you have said all along - I have been well taught 😉

Geez, Penrose worked on black holes way back in the 60s when black holes were the only game in town and everybody and his brother was trying to get some recognition, after the atom and hydrogen bomb work more or less ended in terms of developing the theory anyway. Seems Like a lot of Nobelists try to keep busy and explore the frontiers of physics and quantum physics, or metaphysics. Take the dude who won for physics last year (with two others) for proving the universe is not locally real, he is now a big advocate of the “climate change is a hoax” movement. He claims he can just barely relate to the work that won him a Nobel, it was too long ago. Cut me some slack, Jack.

@TNT I'm not that keen to continue discussing CCC considering I have set out the arguments against its validity in my earlier posts.
Inflation is simply a construction to explain why the CMB looks the same in all directions.
However no one can prove inflation actually happened. It's accepted because it seems to fit observational data well.
Roger Penrose regards inflation as a very artificial theory and he is quite entitled to do so.
But the onus on him is to show that CCC fits observational data - something which to date has not happened.
In CCC, the Universe never goes through a period of contraction - it only ever expands!
Google it! 😉

Penrose's aeons run from bottom to top in the left hand image. You'll notice that only expansion is illustrated.
Scroll to the bottom of my link. According to CCC, the Universe continues to expand until the conditions that existed at the start are recreated.

I got to the end.... "Until then, the story of our universe, its beginnings and whether it has an end, will continue to be debated."

The inflationary state that led to the Big Bang is not explainable in terms of the physics that you or I currently understand.
The energy that ultimately created the universe we know is said to have existed within that early space as quantum fluctuations.
From the Big Bang on things get easier as the physics that we do currently understand takes over.

I tell you what I don’t get with this whole multiverse thing, string theory or ‘ccc’ stuff. We don’t understand dark energy, dark matter or exactly how a photon propagates through a vacuum - other than Lennies ‘ephemeral fermions’ bollox - but here we have TP’s and mathematicians proposing the most fantastic, outrageous stuff with absolutely zero chance of ever proving it. Zero chance. Blinded by science comes to mind.
Wouldn't it be just great if we could solve some of the stuff that needs solving rather than drag physics into the metaphysical realm?

Ethan Segal attempts to explain the quantum fluctuations in the 'empty' space that existed before the Big Bang:

It seems we can't quite grasp that the Universe is unlikely to give up all its secrets.
Meanwhile, theoretical physicists have a job, mouths are being fed and the world keeps turning.
