Scientists have figured out how to find a wormhole in space. But how dangerous is it?

What are wormholes?

Theoretical physicists have hypothesized the existence of such “shortcuts” in

spacetime in the 1930s,initially calling them "white holes" and eventually Einstein-Rosen bridges. A white hole acts as the other side of a black hole. From the outside, wormholes can look like black holes. But while an object that falls into a black hole is trapped there, something that falls into a wormhole can pass through it to the other side.

Since the name Einstein-Rosen Bridges is a bit dry for such an impressive eventuality, it has become more commonly known as wormholes or wormholes.

You can portray a wormhole as a kinda tunnel that connects two points in space-time. This tunnel can be a straight gutter or a winding path. If a wormhole is “passable,” it acts as a shortening of a path through spacetime, connecting two points that would otherwise be far apart. Wormholes can connect different points within the same universe, or they can connect different universes.

The most common way to displaywormholes - imagine that you are holding a piece of paper, which is a normal space. Think of traveling through space as traveling on a piece of paper. Now mark a point at each end and fold the piece of paper in half, connecting the two points together, but not letting them touch. If you were traveling in ordinary space (that is, along a sheet of paper), the journey from one of your marks to the other would take longer than if there was a tunnel or "wormhole" connecting two points on the paper through the empty space between them.

Do wormholes really exist?

The wormhole has never been observed directly orindirectly, but they "exist" in a mathematical sense, when they arise in the solutions of the equations of the gravitational field that underlie Einstein's general theory of relativity. This means that we can split the universe into many parts and then use mathematical equations to describe how those parts fit together.

These field equations are like scaffolding,on which the universe is built. The equations that describe how general relativity or gravity works do not require wormholes, but they do. In other words, one of the possible solutions to the general equations of the field of relativity is a wormhole connecting two points in space-time.

Wormholes are not just purely theoretical phenomena. There are several known problems that make them a reality even in mathematics beyond Einstein's equations.

Why are wormholes dangerous? Where will their discovery lead?

For starters, wormholes are unstable, i.e.quickly collapse. Thus, any possible travelers in space will never be able to reach the other end of the tunnel if it collapses around them. All is not lost, however, because physicists have discovered that the use of exotic matter can keep a wormhole open. Exotic matter, not to be confused with dark matter, is a form that has negative energy density and negative pressure. It is repelled, not attracted by gravity. Until now, exotic matter appears in the form of particles in quantum experiments, so no one knows if enough exotic matter can create a wormhole in one place.

Time travel problem

And even if we could support the tunnel withdiscovered by the ability of exotic matter to repel gravity, other theorists like Stephen Hawking warn of another problem. If ever even one particle hits a wormhole, mathematics requires that the wormhole begin to collapse. This doesn't bode well for intergalactic space and time travel.

You cannot create closed curves like time. A backlash would prevent closed time curves from appearing.The laws of physics are not allow the emergence of closed, time-like curves, Hawking warned when he defended the chronology of time in his 1992 study.

Wormhole potential. What can wormholes give us?

Wormholes are a popular item amongscience fiction fans and theoretical physicists, because such phenomena can open up many possibilities. Humans could travel to another galaxy or explore the existence of parallel universes within human life.

This hypothetical spaceship withThe "negative energy" induction ring was inspired by recent theories describing how space can be curved with negative energy to produce ultra-fast transport to reach distant star systems

And wormholes not only provide an opportunityspace travel, but also for time travel. We could go back to the early days of the formation of our solar system and finally end the debate about how our moon formed. Maybe even solve the mystery of how the supermassive black hole at the center of the Milky Way appeared? And this is just the beginning.

Given that the existence of wormholes is so tempting, we should expect as much research as possible on this topic. And recently scientists have proposed an original solution.

What did the scientists suggest?

Gravitational wave detectors have already discovered mysterious black holes. Wormholes could be next.

Judging byresearch physicists, a black hole spiraling into a wormhole will create ripples in space and space that can be detected and recorded by the LIGO and Virgo gravitational wave observatories.

So far, no evidence has been found for the existence of wormholes. But if they exist, researchers have a chance to detect wormholes using gravitational waves, scientists are sure.

In their theoretical approach, they considereda black hole with a mass five times that of the sun, which orbited a wormhole at a distance of 1.6 billion light years from Earth. The researchers calculated that when the black hole approaches the wormhole, it will spiral inward, as if it were orbiting another massive black hole. This process will be accompanied by oscillations and will create gravitational waves. At first they will look like a standard wave pattern that increases in frequency over time.

But as soon as the black hole reaches the center of the center of the wormhole, called the throat, the black hole will pass through it and the gravitational waves in the first universe will abruptly disappear.

Researchers looked at what would happen if a black hole appeared in a distant world, such as another universe. In this case, the gravitational waves in universe #1 will suddenly disappear.

In Universe No. 2, the emerging black hole would begin to move in a spiral. This could indicate that she was passing through a space-time tunnel.

And these very waves, according to scientists, shoulddifferent from those that occur when two objects come close to each other. Next, the black hole will repeat its movement along the tunnel between the two universes, causing bursts of gravitational waves, as long as its energy allows it.

According to researchers, if universe number 2was our universe, at a certain distance, scientists would have the opportunity to detect these special gravitational waves. This will prove that the black hole went through the wormhole, which means that it exists.

What's the bottom line?

According to the general theory of relativity, which describes gravity as a result of the curvature of space-time, wormholes are possible.

The LIGO Observatory, based in the UnitedStates, or the Advanced Virgo laser interferometric gravitational-wave observatory in Italy, is detecting ripples from black holes or neutron stars. These massive objects revolve around each other before they merge.

Currently, scientists are able to notice suchmergers, having confirmed over a dozen since 2015, and awaiting more confirmation. But at some point, physicists will have to focus on more unusual possibilities, says physicist Viter Cardoso of the Instituto Superior Técnico in Lisbon, Portugal. It's time to look for weirder but more exciting signals, he stresses.

Still, humanity should remember Hawking's warning and remember how dangerous it is.
