No one knows for sure. There are theories, but absolutely none of them can be proved, and I doubt we will ever find out. The universe is expanding firther into what was here before the big bang. Basically, nothing. The universe isn't expanding like a balloon blowing up; the universe is already there, but the objects inside it are spreading out constantly (black holes, stars, galaxies, etc.) The universe isn't expanding; the objects inside are spreading out within it.
there can be hydrogen or star dust. Scientists think there is some ,,dark matter" what we can't see. this matter is probably expanding the known space.
its 13.7 billion years old it covers every area of space its constantly expanding has 5 dimensions
The Earth isn't expanding ... much. It does gain several tons a day from "space dust" falling onto it, but even several tons a day is negligible compared to the overall mass of the Earth. The Earth is actually shrinking. Though it may not seem like it. Slowly, but surely, the land across the earth is sinking back into the water..
During the race to the moon, the government spent massive amounts on space exploration. Today, it is no longer a government priority, so funding for space exploration has decreased. Yet, NASA continues to work on new projects. Currently, however, space exploration is moving further toward the private sector. Companies like Space-X will soon dominate space exploration, and companies that make money expand rapidly.
One reason that people might want a colony in space is because space exploration is exciting and new, and many people would love the chance to live in space. Another reason might be because overpopulation and other issues make expanding the places where humans can live attractive.
Yes.
No. It is space itself that is expanding.
It is space that is expanding. The amount of matter doesn't necessarily increase. This means that the average density of the Universe is decreasing.It is space that is expanding.

The answer is that the expansion of the universe is only noticeable over distances of hundreds of millions of light years or more. Over the much smaller distances found within galaxies and planetary systems its effects are negligible.
What is the name of a vast expanse
That's because the Universe really is expanding. It started as a "big bang", where all the matter and energy in the Universe was concentrated in a tiny space, smaller than an atom - at a tremendous temperature and pressure. From there it started expanding, and continues expanding to this day.That's because the Universe really is expanding.

Space goes on for trillions and billions of kilometres and miles and is still expanding this very minute!
It is expanding, yes. That means that the amount of space is increasing.
probes are sent out to space and they record everything
Yes it is. To be more accurate, it's expanding.
To further our knowledge on the ever expanding universes.
Because of out expanding population
