Answer:
Space is a term that can refer to various phenomena in science, mathematics, and communications. In astronomy and cosmology, space is the vast 3-dimensional region that begins where the earth's atmosphere ends. ... It is sometimes called 3-D space because it contains three distance dimensions.
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes.
