The first appearance of a wormhole in Star Trek was a typically pioneering reference to what was then a niche research topic.

Science fiction imagines wormholes as shortcuts through spacetime. But the original idea suggests they could be something far stranger.
Scientists are trying to figure out if time travel is even theoretically possible. If it is, it looks like it would take a whole lot more knowledge and resources than humans have now to do it.
When it comes to physics experiments, quantum simulations aren’t quite the real thing – but in some cases they’re much closer than you’d expect.
Strangely behaving matter could one day explain some of the mysteries of space.
An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.
Calculations show that wormholes should create a spectacular display of gamma rays that we could try to observe.
Despite his playful optimism, Hawking recognised that the undiscovered laws of physics may prevent time travel.
The pull created by a black hole is so strong that if you get too close to one – even if you are travelling away from it at the fastest speed it is possible to go – you will never be able escape.
A wormhole is like a tunnel connecting two places in space. They would be incredibly useful and are great for science-fiction stories.
The problem is we haven’t found any evidence of them existing.
