    There is the thread Kier started about the Scale of the Universe. This is a video which takes viewers from the Himalayas through our atmosphere and the inky black of space to the afterglow of the Big Bang. Every star, planet, and quasar seen in the film is possible because of the world's most complete four-dimensional map of the universe, the Digital Universe Atlas that is maintained and updated by astrophysicists at the American Museum of Natural History. The new film, created by the Museum,was part of an exhibition, Visions of the Cosmos: From the Milky Ocean to an Evolving Universe, at the Rubin Museum of Art in Manhattan through May 2010.

    That was an amazing video. It really allows you to see the great distance between objects in space and how much "space" there really is. Little ole' Earth isn't even a blip.

    I feel so insignificant. :cry:

    This is why I love what I do! (well one of the reasons anyway...)

    Who in their right mind wouldn't want to study astrophysics??? (Highly subjective opinion I know... but I don't care. :p)

    That was exactly what I thought when I first saw that video.

    yes, I know we are very, very, very insignificant in the grand scheme of the universe. I was just commenting how the video allowed us to actually see that.

    It's okay though! My ego is big enough to overcome it. :D

    Matter is 99% space. If you condensed the universe, it would be about the size of a pea.

    I hate to think what the Gravitational pull of such a pea would be!!!

    Want to feel even more insignificant? This only looked out our universe. If Dark Flow theory holds, then we could have the first evidence of a universe other than our own.

    Consider the implications of that. Imagine our universe as a balloon. As time passes front he big bang, the balloon expands. Within the confines of this ballon is our universe, our space-time continuum, where our laws of physics apply.

    External to our universe is the multiverse fabric, where other balloons are also expanding and exerting these dark flow influences on each other according to the laws of physics that apply to the multiverse - and could be radically different from our own.

    So what happens when the balloons expand into each other? Who knows, but we could hazard a guess by observing what happens when galaxies collide - it isn't pretty. And those are objects which obey the same laws of physics. What happens when two universes with different physical laws collide?

    What makes astrophysics so damned exciting is that science does't limit our imagination, it fuels it.

    Science channel has a special that talked just about this. It was quite fascinating.

    Its funny to think that the size of our egos are bigger than the universe :D

    We are but a speck of dust. With an ego that tells us we are the only intelligent species around.

    If we could somehow have the ability to go between the two in the future, it would be very interesting.

    Not sure of the implications of alternate universes though. Isn't it a rule or something that you shouldn't cross (like going back in time)? :cautious:
    There are some people out there that surprise me and think just that. o_O

    It would be interesting to think if there is a place in the multiverse where there are no rules and anything could happen.
