Sad to say, he is gone. We will never know what he might have come up with next. A fantastically great mind! He will be missed!

Mr. Hawking was arguably the greatest mind of our generation. I can only think of one other who approached his mental ability and that is Albert Einstein.

And so soon after we lost Joe Polchinski, the Brane Master.
Odd that I had never heard of Mr. Polchinski. I wonder why now that I have researched him and found out who and what he was. Truly this was a double blow to our understanding of the universe. Or should I say universes?
Polchinski is a bit more niche; there's a good post about hi by a colleague here: https://profmattstrassler.com/2018/.....oe-polchinski/ He was genius in a similar vein but not as public. He lacked the tragic circumstances to thrust him into the spotlight. He amazed those who worked in his field, but to the public what was he but another egghead? It is a great pity to see both these men go, along with the discoveress of ark matter last year.
The farcical part of it was that the nobel committee refused to give the discoverers a prize (Dark energy? Sure! Dark MATTER... eh.) But happily(?) now that the sole female member of the team is dead they're thinking of it. (Since only the surviving members will get the prize and money.)
There's excerpts, but also a big section on HOW that weird universe works that is intriguing.
Me, I've never been fond of antimatter time reversal (Or time travel in general.) It poses too many problems with causality. Plus given what we see of the universe it seems almost certain there's no big antimatter chunks out there. (And good thing too!) Mind his 'contraterrene' matter isn't really antimatter as such, given our modern understanding of it.
Of course you generate a steady stream of antimatter just by existing; the potassium-40 in your cells occasionally emits positrons. (It's also one of the rare decays that's affected by chemistry -fun fact!)
I like the idea of time travel! It's rather a fun concept to play around with.
Also, WE had unicorns, they were as ugly as hell. https://www.thecut.com/2016/03/unic.....-but-ugly.html Indeed it's surprising how many weird and exotic animals existed in our past.
I wonder, however, if that guy's 'time travel' device didn't function like those in Issac Arthur's canon. (Multiverse, no time travel. Such devices disintegrate you, but in one of the many alternate dimensions random atoms form into a copy of you by pure chance. Like Star Trek's transporters.)
But did they have the same affinity to virgins? somehow I doubt it. =p
I dunno. He always got back to the same universe he left. but then there was something about his 'time travel cage' being an extension of the universe he was born into with some kind of connection between his universe and the one he traveled to. So I think that particular one was one of the less well thought out in a scientific respect, and written more as a fun 'what if' type of story.
'The same universe' is relative; there's a story 'The Parting Of The Ways' where an interunviersal machine is invented. You select a target when you go, but when you go to return you see a 'band' because 'your' universe has split into many slightly different copies while you've been gone. You pick one and everything is fine... until one guy who's been trying to 'game' the bands crashes his device into a copy of himself who had also chosen that universe.
In that case traveling guy again incinerates himself, but in some branch of the universe he left a copy of him randomly reappears -with extras. In most universes he's dead and gone, in many more he 'returns' in a garbled state, or not remembering the trip, or with a six foot vampire bunny instead of a unicorn... But in infinite copies he appears just as if he was returning from another dimension. And in those cases, can we say he HAS traveled? What if the first machine left a small pile of ash behind?
Too much overthiking here for me.
Rabbit brain. They weren't meant for comprehending cosmology and other dimensions. (I mean the most famous rabbit thinkers believed their world to be a literal piece of crap.)
Also,those unicorns gotta get their act together. This is why they died out; waaaay to picky.
(not that that would take much)
You have that correct! Mr. Hawking was almost supernaturally intelligent. Would that our world could be enriched by more like him!
I hope the people honor him by putting
his wheelchair in the Smithsonian Museum.
