http://www.ted.com Legendary scientist David Deutsch puts theoretical physics on the back burner to discuss a more urgent matter: the survival of our species. The first step toward solving global warming, he says, is to admit that we have a problem.

  • Please take all religious time wasting somewhere else. We have things to discuss here.

    If you don't understand what's being said, your perfectly welcome to read books on the subject. Yes I have read books on your beliefs. No i do not find them helpful, fulfilling, conclusive or even remotely spiritual.

    Leave.

  • Noble Prize to David Deutsch.

    thumbs up if you agree !

  • @weasyeasel Ok, so it is further between galactic clusters than between galaxies in the same cluster. We can still see other galactic clusters, therefore someone halfway between two galactic clusters (in inter-galactic-cluster space) can see them even better. Makes no difference to my argument. To say nothing of, Deutsch said nothing of galactic clusters

    Sure, this space is typical. But no one said that life could be created there, and Deutsch's introduction of this is a red herring

  • @VvAnarchangelvV Intergalactic doesn't necessarily mean being on a line connecting two galaxies. Galaxies are usually in clusters, just like stars are usually in clusters. The great voids between galaxy clusters make up maybe 99% of all the volume in the universe, that's why they're typical.

  • Very dark? We can see another galaxies, Halfway to one (in intergalactic space), it would be EASIER to see our galaxy and the other one.

    And all the 'typical' nature of intergalactic space implies is that life cannot be created in intergalactic space. Duh.

  • @phantasmatibus "You would think this self-assured man WAS THERE when everything came to be a "mere" couple of billions ago." Why do you have to be there to establish truths? Science is a way of testing out rival explanations of reality. Reality doesn't just land on our plate fully explained in our senses. "Being there" can be full of illusion and error if we lack good explanations.

  • @phantasmatibus "Can physicists explain the origin of ‘love’ in man through the movements of molecules?".

    Well, it's not the domain of physicists specifically, since love has to do with brain chemistry and evolutionary biology, but in some senses this has to do with molecules of course, so...yes. And please let go of this "it's just a theory" nonsense. Everything is a theory. The question is: which theories offer the best explanations?

  • @Pyramidologie please read about evolution in a decent book or website on the subject. It's not propaganda or nonsense. The origin of life that you asked about required complex chains to gradually form together. As soon as you these chains replicate themselves, however it happens (e.g. by a certain chemical coming into contact) you have the beginnings of what we call life. Look at what a virus is, and how "alive" it is. Life and non-life is a difference in scale, not degree.

  • @jimRRRRRRRRRR people are aloud to have their religions, they give people hope. so stfu

  • meh now that i think about it, i really dont care where humanity stands in the cosmos. wouldnt make a difference if we knew anyway
