Safe Mode: On
Why is our universe fine-tuned for life?

Published on Apr 23, 2012 by TEDtalksDirector

At the heart of modern cosmology is a mystery: Why does our universe
appear so exquisitely tuned to create the conditions necessary for life?
In this tour de force tour of some of science's biggest new
discoveries, Brian Greene shows how the mind-boggling idea of a
multiverse may hold the answer to the riddle.

TEDTalks is a daily
video podcast of the best talks and performances from the TED
Conference, where the world's leading thinkers and doers give the talk
of their lives in 18 minutes. Featured speakers have included Al Gore on
climate change, Philippe Starck on design, Jill Bolte Taylor on
observing her own stroke, Nicholas Negroponte on One Laptop per Child,
Jane Goodall on chimpanzees, Bill Gates on malaria and mosquitoes,
Pattie Maes on the "Sixth Sense" wearable tech, and "Lost" producer JJ
Abrams on the allure of mystery. TED stands for Technology,
Entertainment, Design, and TEDTalks cover these topics as well as
science, business, development and the arts. Closed captions and
translated subtitles in a variety of languages are now available on
TED.com, at http://www.ted.com/translate

    ....Nah. That's Krazy. Let's believe a Mystical Being we can't sense made us. Okay. Brilliant!

  • I love physics and quantum mechanics and all of the deep mysteries of our uni/multiverse, but my question is this:

    How is this knowledge making us better? How is it advancing us as far as being happier and living better? How does this bring us together?

    What is the ultimate goal? It surly can't be to "know everything", so what is it?

    • @TOPDECK There is no ultimate goal; life is random.

    • @TOPDECK you know when there's a mystery to try to figure out and you have a blast trying to crack it, but once you do figure it out, it's no longer fun because it's over. So you move onto the next mystery to bring back that same fun again. Maybe our universe is built just for that purpose, so it keeps us guessing and learning, b/c if we ever did find out everything about it, we'd maybe be unhappy over all? SO maybe the goal is to just keep exploring and figuring things out and having fun doi More..

      The ultimate goal is to keep all physicists gainly employed, most on taxpayer dollars.

    • @wptech I appreciate your reply. I do not denounce such work as a waste. I just think that people should be asking this question.

    • @brako I could not agree more. Our little existence and knowledge is nothing compared to what's out there.

    • @mikecurse Because all there is IS all there is. What is wrong is not the concept of a universe but the scope you have chosen to assign to it.

    • @camy011 I'm using the commonly understood scope assigned to the word, because that is the scope the guy uses in this video, which is that which was formed by "the big bang".

      But I appreciate your point. All depends on what people want the word universe to mean.

  • Other then my strong desire to argue about the semantics involving their use of the term "universe" there is one thing I absolutely agree with; that the idea that the default state of things is "nothing" is wrong. The state of reality is of infinite energy which permeates an infinite sea of infinite space. Reality itself is conscious and reality itself is God.

    • @camy011 it sounded good upto the point you used god in your sentance. we use god for to explain things that we cannot understand. in essence your replacing 1 unknown with another. which leads to a intellectual dead end. in the same way cave men said god made fire. we now understand its a chemical rection. you get the point?

      The same was said of quantum physics... then it gave us awesome touch-screen technology.

      (See quantum tunneling as it relates to modern touch-screens)

      That is precisely where quantum mechanics began: a possibility.

      No (reputable) scientists are calling multi-verse and string theory established facts, but they are being investigated by serious minds in very much the same manner as quantum mechanics was.

      When your great-grandparents were your age, what would they have said about the implications of quantum mechanics? I bet it would sound a lot like your current attitude towards string-theory. Do you really want to be that More..

  • Sure, life as we know it. Change a few variables and we might have unimaginably different forms of life. We can't comprehend it simply because we are used to things as they are.

  • Its the other way round. Its not why is the universe fine tuned to support life! Its how life has adapted to the conditions it has been presented with. Imo.

      These theories are presented as possibilities. Your objections are presented as facts. If history has taught us anything, it is that possibilities are often realized and facts are often disproved.

      I am not interested in challenging your objections. Rather, I am interested in challenging your precepts of what is possible. Remember, each generation seems to accomplish things that former generations deemed impossible.

    • @Rocco_Maximus it all depends on what you think nothingness is. you think in the finite.
      We are mere mortals trying to understand things we have no inkling about.
      Think about it how would a cave man describe our world?
      Dude we are stupid on a cosmic scale

      I am not talking about truth. I am talking about your certainty in statements which might very well be wrong. As I said, you present ideas as facts when they are not necessarily so.

      Look at your statements: "There cannot be an infinite regress of causes" and "We know that it is not the case". How many sentences like this have been proven wrong in the past?

      In thinking this way you not only set yourself up to be proven wrong, you also limit yourself. If G More..

    • @Rocco_Maximus How much time has gone by, we know where we are in the time of this Universe 13.7 billion years, so the infinite passing of time means nothing. This Universe might keep expanding untill Space it's self rip's apart, will that cause a Big Bang so it start's all over again.
