God created the universe, then created galaxy’s, stars, planets and eventually humans – Ok so far so good. But who then created God – Maybe God’s God – we can go on for ever(infinity). Theoretical Physics makes sense to humans but it still could be wrong.I think we as humans still got a long way to go. Lets just try to get along.

Any thoughts about reviving the tired light hypothesis (tlh)? I do realize that the tlh has been relegated to the dustbin of physics history as a bad joke. However, as physicicists and astronomers keep on inventing new explanations for the unexplainable, I’m having second thoughts about ideas we’ve trashed. The falsification of the tlh hangs on a number of self-consistent assumptions, such as Tolman’s surface brightness test of galaxies, the mainstream’s acceptance of relativity theory, the nature and spread of microwave background radiation (mbr), and so on. But I’m not satisfied that the case is closed. A photon traversing the vast distances of space has a likelihood of encountering events that can snuff it out or bleed off energy (offbled energy needs to go somewhere – mbr, anyone?), to provide alternative explanations for otherwise self-consistent observations. Maybe every entity ages (the effects of entropy), even photons.

On the plus side… do I agree with Krauss’ argument of zero total energy throughout the universe, because it gels with my own atheistic axiom that the universe is inevitable, no god required.

Besides the bending over backwards to leave room for ancient superstition and mixing theories as if they were pancake batter, nope, no problem.

This was a very nice lecture, even a total witnit like me could follow it. Without having to understand every detail of theoretical physics. love it.

Just a little thought inspired by one of Krauss’s closing remarks:

If the multiverse is infinite in extent, every possible thing, of course, happens all the time in some region of it. This means that not only will quantum fluctuations produce “this room with everything in it”, they will produce a world full of fossils and geological strata, and in fact a universe full of redshifted galaxies and cosmic microwave background radiation; that is, a universe that completely appears to be 13.72 billion years old, but was in fact formed by a freak quantum fluctuation a few years ago, exactly as it is.

Also, the same phenomenon will sometimes result in intelligent creatures capable of creating universes, and therefore universes created by these creatures.

Problem, atheists?

you gotta be kidding, enjoy the suspence? because your sad now that you know god is real? did i get that right, you are unbelievable. you’re an ignorant and are enjoying it, how ’bout that.
no one can proove god is real i dont care how you got your hallucination, the brain is a machine to ”make sens” of the information it gets, you clearly need a better feeding of information to understand the univers that surrounds you… sorry but your argument that god exist and that once you know that, learning more about the univers is boring, makes no intelligible sens, i don’t know which way you twisted the logic in your brain but it’s too simple, as in stupid.
it sounds like you got raped when you lost your virginity.

The universe is expanding at and increasing speed. So it makes sense to me that there will be other “big bangs” in the future that will need the extra space now being created to exist in. I adore the way you are so sensitive to what others believe. I wish I could have “faith” in God and the afterlife. I did have the near death experience in my life already and I can tell you with 100% truth that God is real and we do still exist when we die in this world. Once you know the truth for yourself, it takes the excitement and wonder that we all have from childhood and throws it right out the window. Enjoy the suspence for as long as you can. Once you have found the answer to the question… “Does God exist?”, You will understand that it is like loosing your virginity. You can’t ever go back to who you were before.

If you think you know it limits your ability to learn……….

A wise man is someone who knows, he knows nothing.
If you think you know all about something, it hampers or limits your ability to learn anything new in relationship to it.

This is the most interesting talk i’ve ever seen :) Lawrence is a great scientist and the mix between knowledge & comic is just perfect! :D So quit whining!

I thought this would be a science lecture – but instead it is some kook talking about science fiction…disappointing!

I don’t mean to offend anyone w/ the atheist comment. Maybe I just cannot understand either viewpoint because I was brought up in an nonreligious household that did not push one view or the other on me, I could understand the pent up frustration that some people have w/ religions, esp. Judaism-Christian-Islamic just because they perhaps grew up in an overbearing household and also the wars perpetuated by members of these religious groups… But still, tis not a reason to hate the religion in general, more of a reason to hate the charismatic leaders who use a philosophical ideal as a tool to dominate, the same can happen with science, when the scientific community ostracizes a member for a controversial belief that goes against their long held traditions… Is science as a community not much different from the incense swinging mysteries of the vatican… in a way at the least? I just like for people to question themselves… to hold any viewpoint so tightly cannot be good for one’s intellect or psyche.
