The famous scientist Stephen Hawking wrote an important paper two weeks before he died, aged 76. He explained how humans could find a multiverse. A multiverse is other universes made at the same time as our universe. He also wrote about how our universe will end. This will happen after the stars run out of energy.
Hawking said our universe came from a tiny point in space. This was after the Big Bang. Hawking said there were many big bangs. Each of them made a universe. All these universes are a multiverse. Scientists could find the multiverse by using space ships. Hawking is also famous for his best-selling book "A Brief History of Time".
