Is it theoretically possible to create a wormhole on Earth? ›

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.

Modified general relativity

In some hypotheses where general relativity is modified, it is possible to have a wormhole that does not collapse without having to resort to exotic matter. For example, this is possible with R² gravity, a form of f ( R ) gravity.

While scientists have no evidence that wormholes actually exist in our world, they're good tools to help astrophysicists like me think about space and time. They may also answer age-old questions about what the universe looks like.

The shortcuts came to be called Einstein-Rosen bridges, or wormholes. "The whole thing is very hypothetical at this point," said Stephen Hsu, a professor of theoretical physics at the University of Oregon, told our sister site, LiveScience. "No one thinks we're going to find a wormhole anytime soon."

Wormholes are theorized but have never been shown to actually exist. No one has any solid idea whether they really exist and it is unlikely one could be created and controlled.

In November 2022, Maria Spiropulu at the California Institute of Technology and her colleagues announced that they had used Google's Sycamore quantum computer to simulate a holographic wormhole.

There is no easy answer to this question.

You need all sorts of strange things like negative energy or repulsive gravity for which we have seen no evidence that they exist. However, an interesting detail is that energy is conserved in the equations which predict wormholes.

There are three methods that can possibly detect wormholes: Negative Temperature, Hawking/ Phantom Radiation, and Kα iron emission lines. This paper discusses whether or not any of these three methods are useful ways to detect wormholes with today's technology and if so, which one is the best and which is the worst.

The negative square root solution inside the horizon represents a white hole. A white hole is a black hole running backwards in time. Just as black holes swallow things irretrievably, so also do white holes spit them out. White holes cannot exist, since they violate the second law of thermodynamics.

We can't see them, but we know that black holes can exist thanks to the groundwork laid by Einstein's General Theory of Relativity. A black hole forms when the mass of an object, like a star, suddenly collapses down to a tiny volume. A small object with a large mass causes a gaping dent in space-time.

Did Cern create a wormhole? ›

Does the Large Hadron Collider create black holes or wormholes that could be used as portals? No. Absolutely not.

For the wormhole metric, ds2 = -dt2 + dr2 + (b2 + r2)(dθ2 + sin2 θ dφ2).

Fortunately, this has never happened to anyone — black holes are too far away to pull in any matter from our solar system. But scientists have observed black holes ripping stars apart, a process that releases a tremendous amount of energy.

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.

We show that wormholes are not mathematically allowed in the spherical metric of a newly-released unified quantum gravity theory known as collision space-time [1] [2] [3].

Humans could survive a trip through a wormhole, but there's a catch. There are drawbacks to this method — namely, such wormholes would be only microscopic, which means even the most hardcore exercise routine wouldn't make humans thin enough for the trip.
