Scientists Are Going To Find A Wormhole To Travel In The Universe
Agree, it would be very convenient if there was a tunnel in the Universe connecting two regions of space-time: flew into it and flew out somewhere in another galaxy.
Such hypothetical tunnels, wormholes, are considered by some scientists to be the product of science fiction. Although, as the same scientists note, if wormholes really exist, they are extremely unstable and quickly collapse.
Let’s assume wormholes are 100% real, but how do we find them? To search for wormholes, we need a black hole, stars in its orbit, and modern equipment to predict the behavior of stars, according to a new study.
It is believed that wormholes are something like a “fold” in space-time.
Imagine an ant crawling over a piece of cloth from one point to another. If the fabric is laid out straight, then the ant will have to overcome the maximum distance, but if the fabric is folded so that the dots touch, then the insect just needs to overcome the fold.
Now imagine that the fabric is space-time, and the fold between the dots is a wormhole. Physicists Albert Einstein and Nathan Rosen published a massive study on this in 1935 and their concept was called the Einstein-Rosen bridge.
Finding wormholes in the Milky Way is not that difficult, according to a new publication by scientists from the University at Buffalo and Yangzhou University.
They argue that the tunnel, as it were, combines two regions of space, which means that such massive objects as stars located at the other end of the wormhole, gravitationally affect the stars near “our” end of the tunnel.
In order for a wormhole to form, an extreme gravitational environment is needed, like around a black hole or even inside a black hole’s event horizon.
So where do we find a massive black hole in the Milky Way and a few stars in orbit around it? The galactic center of the Galaxy is quite suitable, because the supermassive black hole Sagittarius A * rests there , and a whole group of stars revolves around it. If there is a wormhole in that region, then we can fix it by observing the movement of stars.
“If there is a star on each side of the wormhole, then our star should feel the gravitational influence of the star on the other side,” said cosmologist Dejan Stojkovic of the State University of New York at Buffalo.
“The gravitational flow will pass through the wormhole. Using the software it is possible to predict the movement of stars around Sagittarius A* and if we notice a deviation, then it could very well be caused by a wormhole.”
This is actually more difficult than it might seem at first glance.
The mass of Sagittarius A* is 4 million times the mass of the Sun and is by far the dominant gravitational force in the region. Trying to fix the deviation in the movement of one or even several stars is painstaking work.
In the event that the wormhole is inside the event horizon of a black hole, as some theorists predict, then we would not be able to see its effect on the orbit of stars at all, since the effect would be indistinguishable from the influence of the black hole itself.
The good news is that we have a huge archive of data obtained during the observation of the star S2, which is located next to a supermassive black hole. Two independent teams have been monitoring S2 for 25 years, and with each passing year, technology has improved to provide more accurate information.
There will be a lot to analyze, but even if we manage to fix a perturbation in the orbit of the S2 star, this will only be indirect evidence of the presence of a wormhole.
However, if we want to find a wormhole, then we need a starting point and Sagittarius A* with S2 is an ideal pair for this. However, even if we find a wormhole, travel through it is unlikely or completely unsafe. For now,
“Even if a wormhole exists, people and spaceships are unlikely to squeeze through. We need a source of negative energy to keep the wormhole open, and while science does not know how to do this without magic, ”concluded Stojkovic.
But 100 years ago, people did not think that they would land on the moon. Therefore, according to other scientists, it is only a matter of time before people travel through wormholes in space.
Recently, a group of experts from Harvard University, led by physics
professor Avi Loeb, announced the possible presence of alien space
debris in Earth’s orbit, reports the Daily Star.
Leading
space research expert Professor Loeb is confident that the discovery of
such “interstellar objects could help expand our knowledge of possible
alien civilizations and technologies. A team of scientists is conducting
research to confirm that some of the objects in our orbit may be
connected to other star systems.
During an interview with Live
Science, Professor Loeb explained that these objects could enter the
solar system from interstellar space, defying Jupiter’s gravitational
pull and occupying limited orbits around the sun.
Some of them may
have technological origins similar to the probes sent by mankind into
interstellar space, such as Voyager 1 and Voyager 2, Pioneer 10 and 11
and New Horizons.
However,
despite these interesting assumptions, Professor Loeb did not specify
what specific objects he was talking about. In his research report, he
notes that there could be “a significant number” of potentially
detectable objects in Earth’s orbit.
To confirm their assumptions,
the team of scientists uses computer simulations and the Vera Rubin
Observatory (Chile) with a high-resolution camera of 3.2 billion pixels.
This will allow for regular observations of the Southern sky and the
possibility of detecting several captured objects about the size of a
football field.
It is assumed that these interstellar objects passed through the
boundaries of the solar system and may carry unique information about
other civilizations and their technologies. If we could confirm the
origin of these objects, the mysteries that open before us, this would
be a real breakthrough in space exploration.
Professor Loeb
expresses hope that the new research will not only help expand our
knowledge of extraterrestrial technologies, but may also lead to the
discovery of new alien civilizations . Answers to such questions can be
of global significance and influence our understanding of the place of
mankind in the Universe.
And
while there are still many questions and assumptions, the study by
Professor Loeb and his team opens a new chapter in space exploration.
Each new discovery can be the key to deciphering the mysteries of the
cosmos and the possibility of encountering alien life forms.
Betelgeuse, a red giant on the brink of death, continues to show
unusual behavior. After the Great Blackout, which occurred in late 2019
and early 2020, the star became unusually bright. It is now the seventh
brightest star in the sky, while it normally ranks tenth. This has led
to speculation that Betelgeuse is preparing to explode in a
spectacularly large supernova.
However, scientists believe it’s too early to tell, and it’s likely
that this behavior is due to ongoing fluctuations after the Great
Blackout of 2019, and the star will return to normal within a decade.
Betelgeuse is one of the most interesting stars in the sky. It is
about 700 light-years from Earth and is a red giant in the last stage of
its life. It is also an unusual star for a red giant because it was
previously a monster blue-white O-type star, the most massive class of
stars.
Betelgeuse has changed its spectral type because it has almost
exhausted its hydrogen reserves. It now burns helium into carbon and
oxygen and has expanded to a gigantic size: about 764 times the size of
the Sun and about 16.5 to 19 times its mass.
Eventually it will run out of fuel to burn, become a supernova, eject
its outer material, and its core will collapse into a neutron star.
Before the Great Blackout, Betelgeuse also had periodic fluctuations
in brightness. The longest of these cycles is about 5.9 years and the
other is 400 days. But it seems that the Great Blackout caused changes
in these oscillations.
A new paper by astrophysicist Morgan McLeod of the
Harvard-Smithsonian Center for Astrophysics has shown that the 400-day
cycle appears to have been halved. This pulsational cycle is probably
caused by expansion and contraction within the star. According to
simulations carried out by MacLeod and his colleagues, the convective
flow inside Betelgeuse may have risen and become material that separates
from the star.
