Brian Greene: Why is our universe fine-tuned for life?

http://www.ted.com 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.

I allways liked the passion in his voice. Very inspiring....I will another Einstein if I have had him as a professor...

[STEFAN BADARA]

The ultimate theory of relativity is every reference frame is relative and solid in your reality. That is why dreams seem so real. Depending where you are that is your 'solid" reality or objective. There is not fundamental objective reality, is all relative. The only fundamental reality is ONLY consciousness.

[STEFAN BADARA]

All protons, neutrons, electrons are just probability distributions existing in superposition and we as conscious beings we collapse the wave functions of all virtual particles into 3D solid reality (as solid particles). We are doing it and all conscious beings as a collective we agree to it. It's crazy I know but more and more digital physics and metaphysics tells us that fact. At the base of reality there no stuff per say. At tiny levels the reality is just information. Listen Jim Elvidge

I respect people who believe in a religion but if you keep ignorantly saying my belief is wrong then I will pick out the flaws in religion, for the most part.

I'm not saying you're wrong by believing in a God. I'm arguing with you because you can't accept I don't believe in a God and you're getting your argument and facts wrong.

I'm guessing your Christian, and Christianity teaches to love and respect your neighbour, so respect my belief and stop preaching something everyone has heard before

[Dan Lloyd]

Come back and argue when you understand how evolution and quantum mechanics works.

There was no random mutation and suddenly, EYEBALL! A creature developed an eye-like organ, some worked better than others, the ones who could see better were more likely to survive so this repeats for millions of years until 'perfectly working eyes' are created. Same thing applies to the brain.

It's a better and more beautiful image of the universe than having my life controlled by 'destiny.'

[Steven Downey]

You rely on trillions of "just so happens" events. There were random mutations, some of which just so happens to be a perfectly working eyeball which just so happens to be perfectly connected to randomly mutated optic nerves which just so happens to be connected to another random mutation, the brain, which just so happens can perfectly translate what the eye sees into information which the brain just so happens to understand.

All random with no guidance at all.

And you believe that....

[Dan Lloyd]

Just because something is brilliant, beautiful or perfect doesn't mean it had a creator. The fact we have working eyes or kidneys is due to the fact evolution has perfected them over hundreds of millions of years. Those with the better organs will be likely to survive and therefore reproduce and the genes are carried forward.

There is no "obvious" to accept as you so blindly state. If something is obvious it requires fact or evidence. And, as I said above, something being complex is not proof

[milind006]

I have a science question. In case of a multiverse, what would separate different universes? I mean if space, time and energy are quantities and qualities which exist and are defined within an in relation to 1 universe, what else separates two given universes?
