    I heard that if there's a Big Bang, then there's a Big Crunch. I belive it's true, but what if everyone says yes or no?

    The Big Crunch is when Cap'n Crunch comes to Crunchitize us all.

    It's the Big Crush, and it is not a necessary result of the Big Bang.

    Not its the big crunch, but you are right it is not necessary.
    As the dark-energy seems to be expanding the universe against gravity.

    Since cycles are so common in the nature, there is a significant chance that the universe itself is also a cycle, experiencing "Bang-Crunch-Bang" indefinitely. But I would prefer a cold end rather than a fiery one.

    If you know Big Bang, then it is very easy to imagine a Big Crunch. Just think of the Big Bang being played backward, like a videotape. Everything will come together and end up in a fiery ball.

    That would be when the universe will implode on itself. Luckily for us, we might get sucked into a supermassive black hole, with a gravitational force so great, that light itself cannot escape. OK?

    No, there's no big crush. There's evidence that the expansion of the universe is speeding up, and the density of the universe isn't big enough to pull the expansion back in. If the density were greater than what it is now, then there'd be a big crunch, but our density is actually just where it needs to be so that it'll expand until the everything goes cold.

    but you are forgetting that the black holes are going to be created sucking matter inward. then the matter goes to a 2nd universe. all the matter of the universe will go back into a black hole and then a new universe will start at the other end.

    The red shift phenomenon is a widely accepted explanation that the universe is expanding .
    "Expansion of space. The current models of cosmology assume an expanding space. Light will experience a redshift if it travels through expanding space, because the expanding space stretches the light ray, which makes the wavelength longer, which is another way of saying the light gets redder. If the Universe were contracting instead of expanding, we would see distant galaxies blueshifted instead of redshifted. This redshift of distant galaxies looks like a Doppler effect from receding, but in general relativity stretching the space is different from moving the source. These galaxies are not believed to be receding; instead, the intervening space is believed to be stretching, which is subtly different. Nevertheless, astronomers (especially professional ones) sometimes refer to 'recession velocity' in the context of the redshifting of distant galaxies from the expansion of the Universe" Wiki
