| Wormhole Tunnels in Spacetime May Be Possible, New Research Suggests
By Brendan Z. Foster on May 20, 2021
In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world. They might have been a quirk of the complicated math used in the then still young general theory of relativity, which describes gravity. Over the years, though, evidence has accumulated that black holes are very real and even exist right here in our galaxy.
Today another strange prediction from general relativity—wormholes, those fantastical sounding tunnels to the other side of the universe—hang in the same sort of balance. Are they real? And if they are out there in our cosmos, could humans hope to use them for getting around? After their prediction in 1935, research seemed to point toward no—wormholes appeared unlikely to be an element of reality. But new work offers hints of how they could arise, and the process may be easier than physicists have long thought.
The original idea of a wormhole came from physicists Albert Einstein and Nathan Rosen. They studied the strange equations that we now know describe that unescapable pocket of space we call a black hole and asked what they really represented. Einstein and Rosen discovered that, theoretically at least, a black hole’s surface might work as a bridge that connected to a second patch of space. The journey might be as if you went down the drain of your bathtub, and instead of getting stuck in the pipes, you came out into another tub just like the first.
