Wormhole (2024)

FAQs

Do wormholes exist? ›

The throat might be a straight stretch, but it could also wind around, taking a longer path than a more conventional route might require. Einstein's theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date.

If you ever happen to fall through a wormhole, you won't be coming back. It will snap shut behind you. But on the way, you may have just enough time to send one last message home. That's the finding of a new analysis.

Theoretically, a wormhole might connect extremely long distances such as a billion light-years, or short distances such as a few meters, or different points in time, or even different universes.

A wormhole is an intergalactic structure connecting distant points in space-time. It is also called Einstein Rosen Bridge. The entire idea is constructed on some special results of general relativity field equations. In 1957, Physicist John Archibald Wheeler introduced the name “wormhole”.

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.

No one has yet seen a wormhole, but theoretically they could provide shortcuts to distant parts of the universe, or to other universes entirely, if they exist (SN: 7/27/17).

The closest stellar-mass black hole scientists have found is called Gaia-BH1, and it sits only 1,560 light-years away from us.

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.

General relativity. Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.

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.

Do wormholes exist mathematically? ›

Wormholes Do Not Exist: They Are Mathematical Artifacts from an Incomplete Gravitational Theory. Norwegian University of Life Sciences, Ås, Norway. The Schwarzschild solution to the Einstein field equation leads to a solution that has been interpreted as wormholes.

The major distinction between a wormhole and a black hole is that a wormhole is a funnel-shaped space-time tunnel between two points between universes, whereas a black hole is a cosmic body with extreme gravity from which nothing can escape.

When matter falls into or comes closer than the event horizon of a black hole, it becomes isolated from the rest of space-time. It can never leave that region. For all practical purposes the matter has disappeared from the universe.

Spaghettification: A black hole would stretch an astronaut's body into a thin ribbon, since the gravity pulling on their feet is so much stronger than on their head. One-way door: A black hole's event horizon is the “point of no return”. Nothing can escape from within, not even light.
