At the start of the unit we are learning which is space, everybody asked one question about space. My question was if the universe is expanding according to many books, what is it expanding into? I gave recently did some research on that and many scientists say the universe isn’t really expanding. The universe contain s everything, if it is expanding, it could be expanding in another universe or its self. Scientists say with this theory the Big Bang could be wrong. If the universe is infinite, it can’t expand into anything because it is infinite. If it was finite we can never go to the outside of the universe because it is a closed object.
what do you think about my answer? Comment to me and explain.
