Parallel universes. They’re the universes that could exist quite comfortably next to ours, creating a so-called multiverse. What’s more, they could solve a pretty complex problem with black holes: where does the information that falls into them go? Is it destroyed, violating quantum mechanics, or is it enveloped by a blazing firewall, completely defying Einstein’s famous theory of general relativity? It’s a puzzle. That’s where parallel universes come in – according to recent research, it could be that black holes are leaking all of their information from our cosmos into another. This issue, we chat to the astrophysicists who are untangling the conundrum. Turn to page 16 as they reveal how they've solved the mystery of black holes – the greatest paradox ever known.
Elsewhere, we find out why our Solar System is incredibly odd, reveal where time comes from and give you the tools in spotting those fake space photos you find on the Internet. Physicist Michio Kaku, known for his books including The Future of Humanity, dropped by to provide his ultimate guide to the complex universe – he’s made string theory digestible, reveals if the interstellar warp drive is actually going to be possible and has weighed in on the launch of SpaceX’s Falcon Heavy rocket. There’s plenty to get stuck into this month – enjoy the issue!
