Can we use wormholes to travel?

Some wormholes may be “traversable”, meaning humans may be able to travel through them. For that though, they would need to be sufficiently large and kept open against the force of gravity, which tries to close them. To push spacetime outward in this way would require huge amounts of “negative energy”.

Why could we not do space travel by going down a worm hole?

Unfortunately, as far as we can tell, wormholes don’t exist in the real universe. In order to stabilize a wormhole, you have to counteract the effects of any positive energy or mass flowing down the tunnel (that means you ). And to counteract positive mass you need negative mass.

Are there any wormholes in the Milky Way?

Gravity passing through a hypothetical wormhole at the centre of the Milky Way could alter the orbits of nearby stars – according cosmologists in China and the US who are developing new ways to search for wormholes. To date, wormholes have not been observed and it is not known whether they do exist in nature.

Could a black hole actually be a wormhole?

Over the years scientists have looked into the possibility that black holes could be wormholes to other galaxies. They may even be, as some have suggested, a path to another universe. But it doesn’t seem likely that wormholes exist.

What can create a wormhole?

To create a wormhole on Earth, we’d first need a black hole. This is problematic: creating a black hole just a centimetre across would require crushing a mass roughly equal to that of the Earth down to this tiny size. Plus, in the 1960s theorists showed that wormholes would be incredibly unstable.

Why can’t we use wormholes to travel in time?

— Wormholes connect two points in spacetime, which means that they would in principle allow travel in time, as well as in space. However, according to general relativity, it would not be possible to use a wormhole to travel back to a time earlier than when the wormhole was first converted into a time “machine”.” No. Because they don’t exist.

Is it possible to travel through a wormhole to another galaxy?

A science-fiction look at a spacecraft traveling through a wormhole to another galaxy. So far, scientists have not found a way to make such technology possible. NASA Space travel through wormholes sounds like quite an interesting idea.

Why do writers use wormholes in science fiction?

But wormholes also present the perfect way for writers to get around that pesky speed of light, the universe’s speed limit and impediment to fast travel through the cosmos. If characters in science fiction aren’t taking months or years to travel between worlds, a wormhole is likely the reason.

What stops a wormhole from collapsing?

“What we found is that a direct interaction between the [black holes at the] two ends of a non-traversable wormhole can lead to negative energy,” says Jafferis. The resulting antigravitational effect then stops the Einstein-Rosen bridge from collapsing, therefore making the wormhole traversable.
