    One of the things that convinced me there was no Big Bang, is your example of the Hubble telescope. If every direction you look things a speeding away from you, you must be the center of the universe. If we were, the age of the earth seems to be somewhat off.
    Also, if the Hubble was looking at a distance of 13 billion light years, and we are seeing light formed shortly after the Big Bang, then how did we get out here so fast that we beat light getting here. The only way we could see light from shortly after the Big Bang is for us to have traveled several times the speed of light to get here ahead of it and be waiting for it to catch up.

    Another thing about the father galaxies expanding away at greater speed. I think the universe is spinning, just as the Earth spins. If so, then just like on a spinning disk, the points on the edge of the disk are moving faster than a point half way in to the center. Both would move at the same RPM around the center, but their velocities would be different. I ponder on the idea that is why farther galaxies appear to be expanding at greater speed, because they are moving the fastest on the disk, but not necessarily moving away.

    That's the way it's supposed to be.

    This could be on account of how far we are away from everything else. Maybe we are so far away, that no matter how deep we see, the only things we're going to see are about the same number of galaxies in either direction. We are so far from the "edge" that we can't probe past the realm of galaxies that we are part of.

    It's Hubble's Law of Red Shift (the Doppler Shift is for sound, and Hubble Shift is for electromagnetic energy). If an object is moving towards us, it is blue shifted (higher pitch in Doppler); if it is moving away from us, it's red shifted (lower pitch in Doppler). If an object is stationary in relation to us, then it has no shift (constant pitch for Doppler).

    Cosmologists have shown that the deeper we look into space (with radio telescopes), all objects are red shifted. And, the farther away from us they are, the more they are red shifted. This means that the most distant objects our telescopes can see are red shifted the most (moving away from us faster).

    Can't argue that point as it can't be proven one way or another.

    Really, the only thing atheists agree on is that there was no need for a Creator to get the ball rolling and keep things rolling. Whether energy/matter always existed, in some shape or form, is an entirely open question. One that scientists don't have a definitive answer for... yet.
    True, there is no need for a creator to create the universe, if all the material already existed. But at the same time, there is no reason an entity couldn't have taken that material, and used it to create the universe in its present form. Since we will never know until we die, you and I may, or may not, discuss this on the other side. Since I do believe there is a Great Mystery, I'm looking forward to crossing over.

    Yes, everything around us is red shifted, but there is a better explanation for that. There are varying degrees of red shift depending on the direction we look.

    Imagine, for the sake of argument, that we are a particle inside a bomb in a totally empty part of space (no gravity, no surfaces to interact with, etc.). The bomb has an elastic shell that will only expand, not rupture.

    Now, as long as the bomb doesn't explode, we will say that time doesn't exist, since nothing is happening; only when the bomb explodes do things happen and time starts.

    The bomb detonates and the shell expands outward from the center. Time starts now. The shell stretches farther and farther (like a balloon being inflated) outward and the particles inside the shell move away from the center, in an outward direction, also. So, our particle is now moving inside the exploding bomb away from the center, but towards the shell.

    As the space inside the exploding bomb expands outward, the center starts to become empty (everything is moving away from the center....leaving nothing behind). The shell continues to expand with the particles behind it, but the shell is moving a little faster than the particles behind it.

    Our particle, while moving away from the center, is slowing down compared to the shell, which is still expanding rapidly.

    As we look at other particles around us, those behind us are slowing down a little faster than our particle (showing up as slightly red shifted, even though they are moving in our direction). Those particles in front of us, are slowing down, too, but not as quickly as we are (they are red shifted, too). The particles farthest away from us, in the direction we are moving, are moving away from us faster than the ones closer to us (these appear to have the highest red shift).

    The shell is now so far away from us, that we can no longer see it at all.

    If you look far enough behind us you will see space emptying out.

    So, using this example of a bomb exploding, explains what we are seeing space, no matter how deeply we look, everything appears red shifted (moving away from us). The farther away it is, the more red shifted it appears (even behind us because we are moving faster than that which is behind us and slower than that which is in front of us).

    The "light" we are seeing is energy from the Big Bang that has cooled down to microwave frequencies. We are so far away from the wall (shell) that the only thing we can "see" is in microwaves. Visible light from the wall/shell is well beyond our vision (too far for even the HST to see). We are looking at the light that is left (all that's left is microwave radiation).

    I hope the above explanation helps you picture why everything is moving away from us.

    I tried.

    You know, twice this evening I've tried to post a response to you, and just as I was almost done, something whacky occurred, and I lost both post before I could finish. So, I'll wait till in the morning.

    I'm not convinced that Edwin Hubble's "constant" is all that accurate.

    The red shift from galaxies that are further away is greater, implying that they are moving away from us faster, but "redder" light is light with less energy and consequently a longer wavelength. But is it "redder" because it's doppler shifted more (because it's moving away from us faster) or have the photons simply lost some energy flying through all those light-years of mostly empty, dusty space?

    I think the universe is NOT expanding "faster and faster", but rather slowing down and it may eventually stop expanding, then begin to contract via gravity until it forms another big bang and starts the cycle again.

    That's why there's all the fuss about dark matter. Cosmologists are trying to see if there is enough dark matter to slow the expansion down, or not. If there isn't, the universe expands forever; if there is, the universe will eventually stop expanding, then start contracting.

    However, whether there is or isn't won't affect any of us...

    Actually, it doesn't bother me at all, but it would be interesting to know....

    As of yet, I haven't heard cosmologists say, definitely, one way or the other.

    Yeah. It'll be real lonely then. I'm hoping there is enough dark matter to slow things down and collapse it.

    It would be nice to think we're part of a pulsating universe. (Maybe we'd all get another chance to have a world without islam and liberals.... )

    Well, like Krupski, I don't believe the universe is expanding, as that would entail believing in the Big Bang. I don't; I would find it easier to accept a "Big Condensate" theory. That would be where everything in the universe first existed as a form of energy. That this energy was under pressure, somewhat akin to a tablespoon of water in a clear plastic coke bottle lying out in a hot Texas sun. As the bottle heats up, more and more of the water evaporates into a gas and builds up pressure. Then if you suddenly open that bottle and the pressure instantly drops, the gas condenses into water droplets in the coke bottle.

    If the universe happened the same way, then that would explain how our part of the universe was formed 13 billion light years away from another part of the universe and we have been here 13 billion years waiting for that light to reach us. No Big Bang needed to fling us out here at faster than light to beat that light here.

    I also agree with Krupski, that the red shift is not from the edge of the universe expanding away from us, but is more due to the effect of light traveling thru gravity and being slowed or weakened somewhat. That leads to a whole nother discussion about the nature of light.

    Anyway, I've had a long day for an old man, and I'm going to sleep.

    Well, this discussion seems to have stalled for now. Maybe next, we might discuss this thought. Does time slow down as an object reaches the speed of light, or does the object just have farther to travel?

    N/A, go back to the video in post #56 and start at 25:20. It'll answer this question there. (It's not very long....)
