Wormholes, or theoretical bridges connecting distant points in space-time, are quickly torn out of the realm of science fiction and introduced into scientific reality.
In recent years, scientists have made significant progress in understanding these hypothetical deformation tunnels. Citing all this research, John Moores University astrophysicist Andrea Font argues in a new essay in The conversation that it seems more and more likely that real people will one day travel through them. If she is right, it may mean that one day she will be able to travel faster than light – or even through time.
Of course, there are many caveats here – especially since existing wormhole research is much more theoretical than practical.
For example, Font points out that something called negative energy will be needed to stretch a wormhole open wide enough for a spacecraft to travel, but that only minimal amounts of negative energy are generated in the lab.
So, is it possible theoretically? Sure! But is this possible with today̵
But the recent influx of wormhole research suggests that things that now seem impossible may not always be the case, Font said, as more scientists publish work on exotic space structures and the ability to travel through them.
“Wormholes are still in the realm of the imagination,” Font writes The conversation. “But some scientists think we’ll be able to find them soon.”
