    Im with this video all the way up to where they put "Light from a younger universe"

    Proof?

    If everything is to scale, then why are we discovering new things?

    I think this video exaggerates slightly.

    Imagine the day where we could possibly travel through a rupture in space, to the ends, and actually SEE the edge of space.


    ...or finally prove god...

    @steelgrid your right, what we perceive as a younger universe is currently just as aged as ours right now but because it`s so damn far away (several billion light years) the light that we are currently receiving was originally emitted from those systems billions of years ago, so when we view it we see that part of the universe in an younger state. Some times the light is so old that the stars that emitted them have long been burnt out!

    I see things differently to those who say this sort of thing makes them feel insignificant.

    I understand this. That makes me awesome. You understand it. That makes you awesome. There are billions of animals on Earth who could not possibly understand this. Try explaining this to a dog, and they`re fairly smart as animals go.

    Humans, much like us but better educated and a bit more intelligent, discovered this knowledge. Humanity is staggeringly awesome.

    Insignificant? Hell no.

    True @Steelgrid! If we went "outside" the universe we woulddn`t see anything, no light there!
    The light didn`t escape the gravity of the "big bang" for 200,000 years! So any "picture" of what it looked like is pure fantasy.

    Conclusion: Intelligent life probably occurs all over the place all the time, but it is unlikely we will ever be able to communicate or identify another intelligent life form outside the confines of our solar system (im still holding out on life of some sort somewhere in our Solar system.)

    @ 5Cats: Sorry to be a nit-picker, but i have to correct you on that one. The shell of red-green-blue stuff at the edge is the CMB, which stems from 400.000 years after the Big Bang. Before then, the universe was so hot that all matter in it was plasma, which light can`t pass through. That`s why we can`t see further back than that time. What they mean by "younger universe" is that the galaxies are so far away that it takes a significant amount of time for the light to get from that galaxy to us. In other words, the light we`re seeing now was emitted millions or even billions of years ago. So we are literally seeing the galaxies as they appeared millions or billions of years in the past. A younger universe.

    And this is just the ones we know about - I was reading the other day that back in 2003 they pointed the Ultra Deep Field Camera at what appeared to be the "emptiest" part of the sky - no apparent objects whatsoever. The left the camera pointed there with an exposure time of 1 million seconds (about 11 days) and the resultant image showed tens of thousands of previously unknown galaxies, each with hundreds of millions of stars.

    That`s the kind of thing that really bakes my noodle...

    In other words, we are catching particles that was discahrged around when the universe was crated.

    Oh and by the way those talking about what`s `outside` the universe: NOTHING because the universe is everything. Wait let me steal someone`s explanation...here we go:

    "Nothing exists outside the universe. Not even a vacuum. It just doesn`t exist. The universe is everything that exists.

    Although there may also be other universes, they don`t exist in our plane of space-time, so they don`t really exist "outside" of our universe. They just exist."

    You honestly believe that in the 5 - 7 billion years the Earth can sustain life that technology won`t have advanced enough to reach another solar system? Even is light-speed travel is impossible, a ship that would have multiple generations on board to get to a new solar system is possible. (Like in WALL-E) Unless of course we go extinct.. but that`s kind of unlikely.

    "You honestly believe that in the 5 - 7 billion years the Earth can sustain life that technology won`t have advanced enough to reach another solar system?"

    It`s entirely possible that we simply can`t harness enough energy to travel, and even if we would, there might not be any habitable planets within a travelable distance.

    Known and knowable...there is a slight difference. Known=studied and understood. Knowable=available for study.
    Known universe barely extends past our stratosphere...and even then, that`s a tenuous grasp of knowledge about our dear little planet.

    Will humans be around in 5 billion years to see our sun die out? Hard to say, really. Our species, homo sapien sapien won`t be around for sure. We`re due to make our next evolutionary leap very soon, and thanks to our penchant for technology, that will probably be sooner than you think. The marriage of the human body and technology is very close on the horizon. Perhaps soon, we will be homo sapien machina.

    Given the size of the universe, that is true. Even if our descendents develop interstellar travel and expand to an empire of a million stars, that`s still such a miniscule part of the universe that it would be very unlikely to intersect with any other intelligent life, even if they too have an empire of a million stars, even if there are thousands of those empires.

    That was awesome. Really makes your realize how precious this earth is. We are so small compared to the vastness of space and time. Yet, God, while existing outside of all of that space and time, still knows each one of us better than we know ourselves and loves us regardless of what we think of ourselves.
