Will space expand forever?

  • Space isn't expanding. It's relatively static.

    Earth, however is shrinking relative to the rest of the universe, which is why it appears to observers that the universe is expanding.

    If space really expanded per the Standard model of Physics;that would mean that the wavelength of light will also increase accordingly completely infinitively.

    At present, the theory is that the universe and all the matter in it (although I haven't seen definitive about Dark Matter) will expand until everything falls apart. The name assigned by the astrophysics community is "The Big Rip"

    It is very difficult to determine what the density of the universe is, because most of the matter in the universe doesn't give off light that we can see in our telescopes. But we can go out and measure how many galaxies are out there, and how fast they orbit each other (The more massive galaxies are, the faster they will orbit). This gives us a fairly good idea of the density. We can also try to directly measure how quickly the expansion is decelerating by measuring the expansion speeds of distant galaxies. This is also a very difficult experiment.

    Who knows? But it would seem that an uninterrupted expansion of space could eventually affect the micro space within atoms of matter, causing the particles of our very existence to fall apart. That may or may not happen, but long before it could, the universe will have cooled to near nothingness. So any way you look at it from an existential point of view, there is no 'forever' in the physical world.

    The simple truth is, we just don't know right now.

    By being unable to see what's beyond the observable universe, we simply can't see what's beyond the observable universe. So we just don't know. We can only infer based on other data collected. But that still doesn't reslly tell us definitively what's beyond.

    No. After the Big Bang comes the Big Crunch.
