A black hole was discovered in our galaxy that should not exist

The Milky Way is fraught with many mysteries. Recently, one more was added. Chinese astronomers have a discovered a black hole in our galaxy, which, according to current scientific theory, should not exist because of its incredible size. This space monster is 70 times the mass of the Sun and is called LB-1.  The researchers report that after finding the object, could not believe it. The authors of a study published in the journal Nature, consulted with astronomers from around the world and verified the facts for three years.

The discovery of the “impossible” black hole is not consistent with Einstein’s GR

What do we know about the evolution of stars?

To answer this question, it is enough to recall that stars are composed of various elements, from light gases to heavy metals. Lighter elements become heavier as a result of thermonuclear reactions in the nuclei of stars, releasing a huge amount of energy in the process. However, according to the well-known Einstein equation E = mc2, the mass of the star should decrease over time, since it will be converted into energy. Some particles can also burst out like a solar wind, so that over time the star dims and collapses into a neutron star or black hole. According to this theory, our sun cannot create a black hole. Moreover, recently we talked about the fact that in the future our native star will turn into a red dwarf.

According to researchers from NASA, this is what a black hole looks like

In 2015, after the discovery of gravitational waves, scientists first suggested the existence of an excessively large black hole. Gravitational waves traveling around the universe suggest the existence of a black hole 60 times more massive than the sun, but the black hole GW150914, as it was called, was located in a remote part Of the universe, in which stars are very different from our native star. Most scientists believed that an object of similar dimensions was formed by combining two black holes, the collision of which, as we know today, generates gravitational waves. However, the discovery of LB-1 made astronomers think twice. As the researchers write in their work, the incredible size of LB-1 cannot be explained by the initial mass of the star, stellar wind, or thermonuclear reactions. The existence of this black hole disproves our perception of the evolution of stars and the formation of black holes.

Does the discovery of LB-1 refute Einstein’s

general relativity?

Researchers discovered a black hole using the Large Sky Area telescope, the world’s largest galaxy scanner located near Beijing in Hebei Province in northern China. It consists of 4,000 small lenses, each of which can be focused on a separate target. Nevertheless, in the scientific community, the discovery of LB-1 is considered good luck. Dr. David Reitz, Executive Director of the LIGO Laboratory at the California Institute of Technology, compared this discovery to the detection of gravitational waves. However between the detection of gravitational waves and the discovery of LB-1, there is a significant difference – the very existence of such a massive black hole is not consistent with Einstein’s general theory of relativity (GR). Although GR is unlikely to be true, the discovery of LB-1 suggests that there may be gaps.

This is how the collision of two black holes looks, thanks to which gravitational waves appear

Astronomers believe that the discovery of a black hole with a mass 70 times the mass of our Sun in the Milky Way galaxy forces us to review the models of black hole formation and, in general, the understanding of the astrophysics of these space monsters. By the way, we recently told you that acceleration expansion of the universe is also not consistent with general relativity, so scientists are in search of alternative theories.

NASA published pictures of two giant asteroids

NASA published an amazing image of two giant asteroids traveling in the asteroid belt, both of which are larger than some of the cities in the world.

The American Space Agency shared a snapshot that tracks the movement of the large asteroids Lina and Klotho, located in the asteroid belt between Mars and Jupiter. The Lina is about 37 miles (60 km) in diameter and has more than 2,000 days in orbit around the Sun. Klotho is slightly larger, having 50.9 miles (82 km) in diameter and has a 1596-day orbit around our main star.

NASA observed space rocks using the NEOWISE telescope. He also states on his official website:

“appearing as rows of orange dots, the brightest sets of dots belong to the asteroids of Klotho and Lina. Both rotate in the main asteroid belt between Mars and Jupiter, while smaller and more distant asteroids can also be seen on this image ”

These space objects were photographed by NEOWISE as part of the Wise mission (Wide-field Infrared Survey Explorer) asteroid hunting project. 

Cosmic stones within the asteroid belt supposedly pose almost no danger to the Earth, due to the role that Jupiter plays in the solar system. The giant planet has such a powerful gravitational attraction that it actually helps to keep the asteroid belt in place, so objects do not travel throughout the system.

If Jupiter did not use its gravitational pull on these objects in the belt, the inner planets would be constantly at risk of collisions with large asteroids.

“The presence of Jupiter actually protects Mercury, Venus, Earth, and Mars from repeated collisions with asteroids!”, The NASA statement said.

The probability of a major asteroid colliding with the Earth is one in 300,000 chance. However, such a prospect is possible, NASA says.

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.
