Physicists say wormholes could already be detected

(ORDO NEWS) — Hypothetical bridges connecting distant regions of space (and time) may more or less look like the black holes of a garden garden, which means that physicists may have already seen these mythical monsters.

However, fortunately, if the new model proposed by a small group of physicists at Sofia University in Bulgaria is accurate, there may still be a way to tell them apart.

Play with Einstein’s general theory of relativity long enough, you can show how the space-time background of the universe can form not only deep gravity wells from which nothing escapes, but also form impossible mountain peaks that cannot be climbed.

Unlike their dark cousins, these glowing hills avoid anything that comes close, potentially spewing out torrents of particles and radiation that have no hope of ever returning.

Leaving aside the clear possibility that the Big Bang looks exactly like one of these “white holes”, none of this looks like it has ever been observed. However, they remain an interesting concept for exploring the limits of one of the greatest theories in physics.

In the 1930s, a colleague of Einstein named Nathan Rosen showed that there was nothing to be said about deeply curved spacetime. A black hole could not connect with the steep tops of a white hole to form some kind of bridge.

In this corner of physics, our everyday expectations for distance and time are out of the window, which means such a theoretical can traverse vast swaths of space.

Under certain circumstances, matter can even pass through this cosmic tube and come out the other end with more or less complete information.

So to determine what this black hole might look like to observatories like the Event Horizon Telescope, the Sophia University team developed a simplified model of the wormhole’s “throat” in the form of a magnetized liquid ring and made various assumptions. about how matter will circle around him before being swallowed ed.

Particles caught in this violent whirlpool will create powerful electromagnetic fields that will roll and snap in a predictable pattern, polarizing any light emitted from the heated material with a distinct signature. It was the tracking of polarized radio waves that gave us the first stunning images of M87* in 2019 and Sagittarius A* earlier this year.

It turns out that the steaming hot lips of a typical wormhole would be tricky. to distinguish it from the polarized light emitted by the spinning disk of chaos surrounding the black hole.

By this logic, M87* could very well be a wormhole. In fact, wormholes could be lurking everywhere at the end of black holes, and we won’t have an easy way to find out.

This does not mean that it is impossible to know at all.

If we’re lucky and stitch together an image of a potential wormhole seen indirectly through a decent gravitational lens, the subtle properties that distinguish wormholes from black holes may become apparent.

This would require a conveniently placed mass between us and the wormhole to distort its light enough to magnify small differences, of course, but that would at least give us the ability to confidently determine which dark areas of the void have a back exit.

There is another remedy that also requires luck. If we spotted the wormhole at the perfect angle, the light passing through its gaping entrance to us would further strengthen its signature, giving us a clearer indication of the gate through the stars and beyond.

Further modeling. could reveal other characteristics of light waves that help sieve wormholes in the night sky without the need for lensing or ideal angles, which researchers are now looking at.

Imposing additional restrictions on the physics of a wormhole can open up new opportunities for studying not only the general theory of relativity, but also the physics that describes the behavior of waves and particles.

Plus, lessons learned from predictions like these could show where general relativity doesn’t work, opening up a few holes of its own to make bold new discoveries that could give us a whole new way of looking at the cosmos.
