A Universe From Nothing (Lecture)

Lawrence Krauss gives a talk on our current picture of the universe, how it will end, and how it could have come from nothing.

Krauss is the author of many bestselling books on Physics and Cosmology, including “The Physics of Star Trek.”

If you’ve ever wanted to answer that annoying question, “how could the Universe have formed from nothing”, then watch this video.

Lawrence Krauss is funny, informative, and if you watch the entire video (it’s over an hour long, so you might need to pause it a few times), he will blow your mind. Lawrence seems like a pretty cool guy.

  1. “Unprobable”… How embarrassing.

  2. its pointless thinking idk if i’d go as far as saying the worst thing of the human race…

  3. absolutly brilliant rlly worth watching didnt want it too end enjoyed it so much , an you religeous freaks out there who i treat as a joke , religeon poses more questions than it answers? i personally dont give religeous people the time of day there way of thinking is the worst part of the human race?

  4. Amazing lecture by an amazing theoretical physicist! One thing that bothers me though is how much he enjoys putting down faith. One thing we must all remember is that science is the exploration of how, not why.

  5. Oh scientists.  You all are so incredibly wrong.  Every single one of you.  There is a God and you all prove it everyday.  You say the universe came from nothing.  Ok, so the universe popped into existence from no where.  Fine.  So, you say its expanding?  Ok, in order to expand you need an environment in which to expand, or you arent expanding.  This is where they are wrong.  The universe is what encapsulates all that is expanding and all that is.  If it was expanding itself, you then need to explain what it’s expanding into.  What is on the edge of that expansion in which its expanding?  Exactly.  You can’t understand that because your brain wont allow it.  Everything that is in anything, is inside the universe.  Anything on the outside of the universe, we cant comprehend because everything we know is inside it.  Wait, another universe you say?  Ok then, whats on the outside of that?  Or those?  EXACTLY.  Human brains were not created with the ability to understand this.

    • Our brains do not allow us the understanding of the universe, therefore God exists? How can you try to argue blind faith with a poor attempt at scientific thinking?

      There is always one commenting on every science documentary known to man. I mean what are they even doing in the science section? Given their problem with science and their adoration of faith, you’d think they wouldn’t enjoy watching programs that challenge their beliefs.

      If they are searching science documentaries and lectures to listen to theories and attempt the use of reason in their judgement of them (such as ‘Look’ has, however poor it may be), is it not surprising that they maintain a belief that does not require proof??

    • the problem with believing there was a ‘creator’ as in a GOD is….you sequentially end up with a ‘creator paradox’, which means who created the creator and who created the created of the creator, and so on……so the idea of a concious creator falls down immidately if you consider this……any thoughts?

      • Two things

        This is not directed at anyone directly but
        When we put someone down for having a perspective other then you, it shows your inability to accept another persons thoughts or opinions; whether you agree with them or not. This I believe makes you the weaker person.
        I see the problem as this and I could be wrong but ….
        Evolutionary and religious viewpoints on the origin of the universe are both theories.  Neither can be proven conclusively.
        We weren’t there, we are unable to know exactly what happened. It is conjecture.
        Scientific approach is testing for a result in order to see whether a hypothesis you are studying is correct not. At school we used to teach fair testing in science i.e. all testing is fair and equal i.e. the same, repeatable.
        So far this has not happened. The natural order is for order to descend into chaos.  Things naturally deteriorate not improve.
        The book In six days: Why fifty scientists choose to believe in Creation by  John F Ashton  which has papers by PhD’s is an interesting read.
        We need to think outside of ourselves.

        • Religious viewpoint on on the origin of the universe is not a theory, it is a superstition. There is a BIG BIG diffrence. You want to believe in superstition and you think that because a handful of ignorant scientists also believe in it that it is somehow valid. There are idiots in every profession. There is as much validity in believing in a religious beginning as there is in believing that the easter-bunny and santa-clause made the world from christmas gifts and eggs. Science makes theories with rigorous testing and proven methods. I think all religious people that dont believe in evolution and etc should not be allowed to use technology that science has brought us! All computers, the internet and atomic energy and everything should be exclusiv for people that trust in the scientific method! The religious people dont believe in the method and thus should not reek the benefits of it!

    • The universe is expanding into nothing u idiot. Its your brain that can’t understand the definition of “nothing”
      How can u believe in god when there is not 1% of any evidence for it. Science can prove 99% of everything. The world would be a much better place if people just accepted that there isnt a god

    • … and God explains all of this for you? lol

  8. lawrence krauss is the greatest living physicist of our time,although I’m British and my loyalty should lie with Hawkins it does not.

  9. When I first saw how long this was, I was a bit deterred, given it’s a lecture.  But now that I’ve watched it all, I’m wishing he’d been given more time.  So worth watching.
