Last fall, we feaÂtured a talk by the hot-shot theÂoÂretÂiÂcal physiÂcist Lawrence Krauss, “A UniÂverse from NothÂing,” which answered some big enchiÂlaÂda quesÂtions: What is our curÂrent underÂstandÂing of the uniÂverse? When did the uniÂverse begin? What came before it? How could someÂthing come from nothÂing? And what will hapÂpen to the uniÂverse in the future?
The lecÂture gave a snapÂshot of the thinkÂing laid out in Krauss’ newÂly-released book by the same title: A UniÂverse from NothÂing: Why There Is SomeÂthing Rather than NothÂing. The book just hit the stands, and right now it’s #51 on the AmaÂzon bestÂseller list. Not bad for a text that delves into the comÂplex mysÂterÂies of dark matÂter, quanÂtum mechanÂics and cosÂmolÂoÂgy.
In case you missed the origÂiÂnal lecÂture, we have postÂed “A UniÂverse from NothÂing” below for your viewÂing pleaÂsure. (It has racked up over a milÂlion views on YouTube.) And you can catch the video trailÂer for Krauss’ new book right above. Find more great physics videos in our colÂlecÂtion of Free Online CoursÂes and Great SciÂence Videos.
i postÂed a comÂment here and it was deletÂed. why?
obviÂousÂly too objecÂtive. — all comÂments have been delete. http://www.opensopa.com
I realÂly enjoyed this one too:

I had that theÂoÂry years ago, it’s all logÂic. No matÂter what everyÂthing must come from someÂthing. Thus, someÂwhere down the line someÂthing must come from nothÂing. NothÂing is still someÂthing othÂerÂwise we wouldÂn’t be able to clasÂsiÂfy it so the next quesÂtion becomes, where did that nothing/nothingness come from? Is it realÂly nothÂing or just what we clasÂsiÂfy it as?
I don’t think Krauss realÂly answers this QuesÂtion. When he talks about how our uniÂverse comes from nothÂing. This nothÂing he refers to is a quanÂtum vacÂuÂum. In this “quanÂtum vacÂuÂum” under one of a dozen interÂpreÂtaÂtions of quanÂtum mechanÂics, parÂtiÂcles pop in and out of exisÂtence. The probÂlem with this explainaÂtion is a quanÂtum vacÂuÂum isn’t “nothÂing” it exists in empÂty space, and needs time for parÂtiÂcles to pop in and out. And both space and time began at the Big Bang.
He doesÂn’t even begin to explain how an event can occur, like the Big Bang, when time doesÂn’t exist.
Krauss is brilÂliant!!!
You are an atheÂist and do not believe in GOD! EveryÂthing you say is geared to provÂing that GOD does not exist. On judgÂment day then you will know the truth!
“BrilÂliant” as in nothÂing realÂly means someÂthing. Am I more brilÂliant if I say someÂthing is someÂthing?
