The Krauss Depression

[Blunt Force Trauma]

Find yourself 65 minutes, grab a stout and a smoke of your choice, and sit back and listen to the latest in cutting edge reality physics.

Krauss is at his disarming best with the latest reviewed theories with an almost Moses Mendelssohn humorous demeanor.

Something from nothing

I'm out - I did watch 10 minutes very interesting plot

The growing certainty that 'we', meaning our universe, may very well be a bubble in an infinite sea of foam, which could range in size smaller than quarks to expanses that make our observable universe seem like a virtual particle, as well as time scales so small and large to never be visualized, AND that all of this has a zero sum energy to suggest it came from "nothing". . . is mind numbing. That there is no beginning or end to it, is far too much to wrap one's head around.

To imagine that there could be universes that could have come into existence, flourished, and died an infinite amount of times WITHIN JUST ONE atom in your body is too much to grasp.

When I WAS attending the university years ago & took Physics for scientist & Engineers - Newtonian Law reigns supreme still. What a clever guy developing laws of motion

The concept isn't exactly a new one - but certainly has been polished to match up with current knowledge in physics.

I remember reading old scifi short stories written half a century ago or more that said pretty much the same things.
It's certainly a grand concept, but I don't buy the whole "something from nothing" aspect.
I do like the recent theories about white holes and black holes feeding one another...a 'big bang' is the output of material from a black hole - the expulsion or 'big bang' would be the white hole event.

Yes, it's not new, but with dark matter and energy now solidly in the mix in the past 12 years or so, a new insight is developing. Also, something from nothing goes back decades with virtual particles popping in and out of existence from 'nothing' before they can violate the conservation of energy. And of course made famous by Hawking with his theory a black hole event horizon allows half the pair to stay here in this universe.

Need funding for another Hubble Space Telescope, it's 2012 with plenty of updated technology. Instead of funding war which goes nowhere fund science

That'd be the James Webb... which almost got cancelled and now has only been delayed.

Which is what I meant.
To me "from nothing" means "we don't know yet."
