Our world is a rather strange place. Physicists have long assumed that our Universe can be only one of many, and some of the most mysterious objects in the Universe – black holes – can turn out to be portals to other worlds. But what if black holes are not portals to other worlds, but portals for traveling through space and time? 

Indeed – black holes balance on the brink between science fiction and science fact. On the one hand, scientists saw how black holes absorb stars that were too close to them. On the other hand, at the edge of a black hole, is a place known as the event horizon , from where nothing can escape, not even light. But what happens to a spaceship if it gets there?

It is possible that once inside a black hole, you can be in another galaxy

What happens inside a black hole?

Given all the data we have about black holes , scientists believed that nothing good awaits us inside these massive objects. However, the latest computer simulation showed that once inside a black hole, you can move to a distant part of the Milky Way or to another galaxy. In this case, one of the safest portals may be a supermassive black hole in the center of our galaxy, – Sagittarius A *. Business Insider writes about this with reference to researchers from NASA.

We do not know what is happening beyond the event horizon inside the black hole. Scientists agree that if you go far enough into a black hole, gravity will become so strong that it will destroy everything in its path. But sci-fi films are more optimistic – in them black holes are portals for traveling through space and time, or portals for traveling to other worlds. In fact, in the center of each black hole is a point of infinite density, called a singularity. It is the singularity that gives black holes a strong gravitational attraction. For decades, scientists believed that the singularities of all blacks are the same, so everything that passes through the event horizon will be destroyed in the same way: everything will stretch and stretch, like infinitely long spaghetti.

Here is the first ever black hole photo

But all this changed in the early 1990s, when various research groups in Canada and the United States discovered a second singularity called the “mass inflation singularity.” This discovery suggests that you can theoretically survive a journey through a black hole. It will stretch you but ultimately not kill you, that is, you can survive the journey through a black hole. More precisely, through a large rotating black hole in which singularities of this type exist. Now astronomers need to find a suitable black hole to test this theory. And the best place to check is Sagittarius A * – a supermassive black hole in the center of our galaxy, which is located at a distance of 27,000 light years from us.

Given that there is no way to get there, verification of this theory is possible only with the help of computer simulation. That’s exactly what scientists from Umass University of Dartmouth and Georgia College did. According to the results, once inside Sagittarius A * you can feel nothing at the right speed and at the right time .

On the other side of the black hole

Black holes are one of the most mysterious objects in the universe

As for what happens when you get to the other side, you can’t say almost anything. But the authors of the study have their own ideas. According to the researchers, there is a chance that you will end up in some remote part of our galaxy – potentially remote from any planets or stars, and according to the second probability, you may even end up in another galaxy. It all depends on how far you manage to get into the black hole. Nevertheless, scientists believe that more research is needed before we approach a successful journey through a black hole. But when we are ready, the supermassive black hole in the center of the Milky Way may turn out to be our lucky ticket to another galaxy.

A “Meteorite” falls in Nigeria destroying more than 100 houses and leaving a huge crater

On the morning of Saturday 28 March 2020, a large meteorite crashed in Akure (Nigeria), destroying more than 100 houses and leaving a 21-meter crater on the ground. Experts from the Awbaowo University of Obafemi (Nigeria) denied the local police who initially claimed that a bomb explosion had created the 21-meter crater.

According to Nigerian sources, the explosion destroyed the Akure-OVO road and seriously damaged dozens of houses, from 50 to 100, as well as schools and churches.

It is interesting that initially the authorities denied the meteorite’s fall and claimed that the cause for the explosion was a truck with explosives, which was transported to a neighboring state. Ondo State Governor Rotimi Akeredolu said the blast was an accident.

Then the version changed and the truck was no longer just transporting explosives, but it was supposedly a terrorist act.

Now, a team of experts and scientists came to the conclusion that everything that happened was a fall of a large meteorite.

The blast that shook Akure, the state capital of Ondo, on Saturday, was caused by a giant cosmic rock, a team of experts concluded.

Led by Adepelumi Adekunle, a professor of geophysics and seismic engineering at Obafemi Avolovo University, the team said that the meteorite entered the atmosphere of our planet at a “43 degree angle”.

Adepelumi Adekunle’s report reads:

“My research team conducted a detailed analysis of the impact site. A round impact crater was discovered with a diameter of 21 m and a depth of 7.8 m, which indicates a natural phenomenon.

– It was found that water is oozing from the edges of the crater. Preliminary field studies of vibration, noise, seismicity, analysis of water, radioactivity, rocks and soil were carried out.

“Our findings suggest that the impact of the explosion covers a radius of 1 km from the vicinity of the crater.” No signs of fire or burning were found in the vicinity. “

“No signs of radioactive radiation were found within the crater and in the immediate vicinity of it. Field data indicate that a meteorite from the asteroid belt was moving at high speed from space, and fell at an angle of 43 degrees in the southwestern part of the country “

A local source said that after the incident, no one was missing and no one was killed. The most interesting thing in the report is the mention that “unusual stones and strange metal objects” were found inside the crater. So what actually fell in Nigeria – a meteorite or a UFO?

Something strange is happening with the interstellar comet 2I / Borisov

When astronomers see something in the Universe that at first glance seems to be one of a kind, this will certainly cause great excitement and attention.

This mysterious guest from the depths of space first attracted the attention of celestial observers at the end of August 2019, when it was officially discovered sweeping through the solar system along a trajectory indicating interstellar origin.

After analyzing the object, astronomers identified it as a comet called Comet 21 / Borisov, which is the first identified comet and the second observable interstellar alien after the infamous Oumuamua, who arrived here from another star.

NASA claims that they do not know where and when the comet began to move towards our Sun. Gravity of the Sun slightly deflects its trajectory, but cannot capture it due to the shape of the orbit and its high speed of about 160,934 km / h.

Hubble showed that the comet’s heart, a loose accumulation of ice and dust particles, was probably no more than 975 meters across, about the length of nine football fields.

Now, this month, astronomers have discovered that something strange is happening by checking the object.

In the next video, nemesis maturity explains what happens to this mysterious interstellar guest.

Hundreds of exoplanets with two suns discovered

Until recently, in search of inhabited exoplanets, binary star systems were completely undeservedly ignored. Exoplanets with two suns have long become familiar places where the events of science fiction novels and films are unfolding.

One of the most striking and well-known examples of this is the desert planet Tatooine, the birthplace of Anakin and Luke Skywalker in the famous Star Wars movie saga. But only in 2011, NASA scientists using the Kepler space telescope were able to provide clear evidence that such exoplanets that revolve around two stars at once really exist. The planet discovered then was called Kepler-16b.

Despite the impressive discovery, scientists continued to believe that such planetary systems are extremely rare due to the complex attraction of two suns at once. But this opinion turned out to be completely wrong, writes astrophysicist Paul M. Sutter in an article for Space.com. This was revealed as a result of a new analysis of millions of stars and the discovery of exoplanets that have been recorded and cataloged by the ESA space telescope since 2013.

In fact, there are only two scenarios in which planets cope with the complex gravitational forces of two stars. If the stars are located very far apart, the planet can rotate around one star – then the other will be visible from the surface of the planet as a brightly shining star in the sky. In another case, both stars are close to each other – then the planet rotates at a safe distance around its double sun, as if it were just one celestial body.
These seemingly unbelievable stellar constellations are likely to occur much more often than might be expected.

Researchers have discovered during their targeted search already 300 exoplanets that could “boast” of double suns. Until now, astronomical science has actually ignored binary stars to search for (inhabited) exoplanets, because scientists considered their occurrence extremely unlikely in principle. In the case of discovered 300 planets, it is most likely a question of constellations, in which binary stars were incorrectly interpreted by the telescope as single stars.

Sutter speaks of decades of scientific confusion and uncertainty: “Since we did not often pay attention to the search for planets in binary solar systems, we had little chance of finding them. We didn’t look for anything like that, therefore we didn’t find it. The researcher believes that the realization that such double suns are very common should definitely be considered when searching for new exoplanets.
