The universe has no color. In fact there's nothing there. Only emptiness, so there's no color. Unless it's the stars. And there can be many colors
Answer from: Ali G.:
If we talk about objects (and they are part of the universe), they have all kinds of colors. Nebulae, for example, look quite fascinating because of "the color".
But if we talk about the universe as a space, it is colorless and that is why it seems to us black (I know, it sounds meaningless, but in fact it is, because it does not emit and practically does not reflect light). Except that you can't call it empty, because there is no vacuum as such anywhere in the cosmos.
- What if the universe, say, in a trillion years stops expanding? And everything goes backwards to one point, then an explosion and so on.
- Are the particles at the opposite ends of the universe connected by any forces? If not, can we say that they are elements of different independent universes?
- What does the frontier of the universe look like, and is it?
- How much of the cosmos can we "see"? If intelligent life exists in the Universe and sends signals into space, what are the chances of intercepting these signals?
- Why are quantities such as the greatest speed and the lowest temperature possible if the universe is infinite?
