This, I like. Makes my head hurt a bit but it's worth it.

Gives me a perspective on how "settled" ANY science is.

Reading Hawking, Thorne and others first helps with the background.

It is late an night and I got through about a third of that video. Not sure hom much I uderstood, but I will say that the best way to watch it is in the dark on a large screen. Prettiest damn pictures I can recall seeing

When Hawking wrote A Brief History of Timeway back when I read it and got a little of it. Black holes...one way street!

Then he wrote an appended version.

Information (matter for our purpose), he'd come to believe, did not disappear forever but was radiated back as energy as black holes "evaporate".

Thorne tied a bunch of it together in Einstein's Outrageous Theory. He was easier to understand than Hawking.

But it's been a long time and homeboy's video title was kind of a challenge so I watched and commented.

Is there a "definition" of space-time to change?

Great post BigMike. I just wish more folks here were interested in this. For me it is hard to imagine how they are not. I had a great discussion with
Dr. Rudy Schild, https://en.wikipedia.org/wiki/Rudolph_Schild , some years ago regarding my flying encounter.
A lot of good info can be found in his articles. We did agree that the power of thought may be an answer to how vast distances are traversed by Alien Civilizations .

The more we know, the more we realize that we don't know anything.

Geocentricity was "settled" science once.

Just think of this little problem...

...if "dark matter" and "dark energy" don't exist cosmology is in a place where they'll have to go back and redo their math.

"Eternal collapse"?

The description sounds right to me except for the "eternal" part since even by their own reckoning black holes themselves had a beginning and "eternal" is diametrically opposed to the laws of entropy.

It'll be interesting to see where they're forced to go with their math if it's proven dark energy and dark matter don't exist because that's what has to exist if the path they're following now has a dead end.
