Lawrence Krauss & Marcelo Gleiser on Something from Nothing

It's good to be confident, but when Krauss' confidence spills over into what sounded like the pure hubris of a 3 yo, I believe that goes too far. It was amusing to listen to after a while, because it was clear he was completely blind to his own belief system: that science can KNOW, and that physics is not 'man-made' but that 'mathematics were dictated by the universe' (quoting a friend).

Just listened to the interview with Krauss yesterday. I didn't feel that his book was as carefully written as it could have been. The article linked below seems to go a long way to bridging one of the gaps in his discussion.

What struck me most was Krause's arrogance and his demeaning of any other discipline. Can you imagine how drab and bleak life would be if his ilk were all we had. I would like to hear Rabbib Jonathan Sacks debate Krause.

It is useless to try to balance truth (science) with wishful thinking (spirituality). "Science is a way to keep from fooling ourselves" - Feynman. Science and mathematics are mysterious, amazing, beautiful, and effective.

If you think that science = truth you're deluded. Thankfully few of even the most pedestrian science workers think that. Science is a methodology for seeking to acquire knowledge. Many of us think it's the best way but that doesn't make it *the truth*.

BTW much of the knowledge you cling to now as science was discovered because 5 or more decades ago, scientists were able to work free from the pedantic and dogmatic thinking of much of the masses.

"You wouldn' t have any particles, all the radiation and so, there's literally nothing in it. But that nothing is actually quite complicated because of quantum mechanics and relativity. It turns out empty space is a boiling, bubbling brew of virtual particles, popping in and out of existence in a time so short that you can' t even measure them."

So nothing = there's literally nothing in it yet nothing = virtual particles popping into existence. Therefore virtual particles = literally nothing. Fail.

If he said "prior to the universe we have today there were virtual particles" that would at least be congruent.

So in this nothing there are already the laws of QM? Interesting so again we come to the question of how. A quanta is a unit of energy so where did that energy stem from?

The only truth here is "we don't know." Any person who can't bring themselves to accept that isn't IMO really seeking knowledge.
