Future Space
One of the most essential mysteries of the universe that science has not yet been able to solve is whether life exists anywhere else in the universe besides on Earth. Scientists have tried to answer this question for years without a clear answer. There could be life out there, but if that’s the case, why haven’t we found it yet? If life is something normal in the universe, where is it? Why haven’t we found other planets full of life like Earth? Why haven’t we received radio signals from other civilizations?
