Sergei Nayakshin of Leicester University, UK, Rashid Sunyaev and Sergey Sazonov of the Space Research Institute of Russian Academy of Sciences put forward a hypothesis, that large dust clouds that surround the supermassive black holes are composed of dust particles, that are formed from planets and asteroids. According to scientists, the black hole can capture planets and asteroids in the nearest stars and grind them when captured by the planets and asteroids, attracted by a powerful gravitational field of a black hole, faced with many similar objects, and as a result of collapse before the formation of tiny particles of dust. According to scientists, this hypothesis may finally explain- why the majority of galaxies nuclei enveloped in vast clouds of cosmic dust.

Black hole was first photographed in the cloud of gas- VIDEO
Friday, 28 September 2012 15:18


A group of astrophysicists led by Sheperd Doeleman of Haystack Observatory in Westford, USA able to take a picture of the jet (jet is a matter, that emits a black hole) in the center of the galaxy M87, which was first proved the involvement of black holes to the formation of powerful jets in galaxies, as astrophysicists have long debated. According to Sheperd Doeleman, in the study of the nucleus of the galaxy M87 with radio Event Horizon managed to get a photo, for the first time clearly show, that the jets arise from the activity of supermassive black holes, as these images could represent the first time though, would be a circuit that is peculiar to black holes, since the image of the black hole can not be obtained in principle, because the force of gravity on the surface of the black hole is so great, that the light emission never leave the black hole. Supergiant elliptical galaxy M87 is located in the constellation of Virgo, in a distance of 54 million years from Earth. Supermassive black hole at the center of the galaxy M87 has a mass 6.6 billion solar mass and is one of the heaviest black holes in the Universe.

Black holes

Сообщение MashOlly » 07 ноя 2012, 03:49

Every now and then, I speculate, could a black hole really just be a really heavy neutron star? I figure that since the same process that forms black holes also form neutron stars, that both would consist of roughly the same materials.

Could this assumption be correct?

Black hole has eaten the supernova Swift J1745-26 in live broadcast of NASA- VIDEO

Tuesday, 23 October 2012 09:35


According to NASA, a powerful burst of X-rays, which was caused by the explosion of supernova Swift J1745-26 near the center of our galaxy ( Milky Way), has revealed a previously unknown black hole. The discovery was made by X-ray telescope of orbiting observatory SWIFT, which is designed to record and observe of cosmic gamma-ray bursts (launched at November 20, 2004 from the Cape Canaveral of launch vehicle Delta-2 7320-10). NASA astronomers in first time have recorded, as a substance, that remains of a supernova explosion Swift J1745-26 was absorbed by the black hole, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... 45-26.html

Ears of Black hole were found in the center of the galaxy M87- VIDEO

Tuesday, 30 October 2012 10:15


In the Astronomy & Astrophysics magazine was appeared an article of astronomers from the Astrophysics Institute of the Max Planck Society in Garching, Germany, under the direction of Francesco de Gasperin, that in for the first time astronomers have obtained an images of specific areas in the disc of the galaxy - the so-called "ears of black holes", which are an areas, where are located a matter, which jets of huge black hole ejected in the galaxy M87. According to Francesco de Gasperin, the processes that form these "ears of a black hole" is very similar to the processes in the Earth's volcanoes, as well as in volcanoes, matter ejected at high speed. The discovery was made on the basis of data on the radio emission of the galaxy M87 at frequencies from 20 to 160 MHz, which were received by the radio telescope LOFAR, VLA radio observatory in New Mexico and the German telescope "Effelsberg" in Bonn. According to Francesco de Gasperin, M87 is a kind of "star metropolis" in the constellation of Virgo, in the center of which is located a huge black hole with a mass of 6 million times more of the mass of the Sun, VIDEO: http://hainanwel.com/en/unusual-world/2 ... -hole.html

Found the heaviest object in the Universe-a supermassive black hole has a mass of 20 billion solar masses- VIDEO

Wednesday, 28 November 2012 22:37


In the Nature magazine published an article of scientists from the Institute of Astronomy of the Max Planck Society in Heidelberg, Germany, under the direction of Remco van den Bosch, that found the heaviest object in the Universe- black hole in the center of the galaxy NGC 1277, which is located at a distance 228 million light-years off the Earth in the constellation of Perseus, - has a mass, that is nearly 20 billion times more the mass of our Sun. Thus, the black hole at the center of the galaxy NGC 1277 is almost twice massive of the previous record holder in the Universe- black hole in the galaxy NGC 4889 with a mass of 9.8 billion solar masses. Opening the black hole at the center of the galaxy NGC 1277 was made with an infrared spectrometer on Hobby-Eberly Telescope, which is located in McDonald Observatory, USA. According to Karl Gebhardt from the University of Texas at Austin, USA, the galaxy NGC 1277 is very unusual and do not like to the other galaxy, as the black hole at its center contains more than 14% of the total mass of the galaxy, that there is nowhere else . In the video below shows the animation of a black hole in the galaxy NGC 4889, which made of Remco van den Bosch, 1 second of video corresponds to 22 million years, THE VIDEO: http://hainanwel.com/en/unusual-world/2 ... -hole.html

Time travel through a wormhole is possible in reality-VIDEO
Friday, 23 May 2014 15:00
Physicist from Cambridge, United Kingdom LUKe Butcher in his new work describes a special mode of existence of "wormholes", that suggests the possibility of sending information over a relatively long period of time and, therefore, theoretically suggests the possibility of time travel. Scientists have calculated that at a certain radius of the neck "molehill" negative energy of Casimir will be enough to for some time there was a stable configuration of the wormhole, allowing the photon to leave its limits and, therefore, to convey information.The presence of negative energy Casimir is a prerequisite to an object able to get out of the wormhole. Casimir energy associated with the quantum Casimir effect - the attraction of two closely spaced electrically neutral vacuum metal plates separated by a distance much smaller than the linear dimensions. With this arrangement, the plates quantum effects become important due to the existence of the charged virtual particles that make plates converge. Pressures on these plates is so negative ( its nature is not a mechanical ), attributed to the same sign and the Casimir energy.Wormholes are a "tunnel", that linked regions of space- time. Wormholes can connect different parts of space-time or even different Universes. Mathematically Wormholes arise as a special class of solutions of the equations of general relativity. Physicist Michio Kaku in his book "Physics of the Impossible" said about reversible wormholes, most promising scheme of a time machine. Conclusions in theoretical work of LUKe Butcher is once again confirm, VIDEO:

Biggest and oldest black hole discovered in space - VIDEO

An international team of astronomers have discovered a very massive black hole - its mass is 12 million Suns, it is the largest of the known quasars in the early era of the formation of the Universe.

Syaohuey Fan of Beijing University said that so massive and bright quasar - a mystery to scientists, because it does not fit into the existing theory of the formation of black holes in the Universe. As such supermassive objects can grow so fast in the early Universe? And as such black holes interact with the galaxy?

Fan and his colleagues observed a few distant quasars using built in 2007 in Lijiang telescope (the largest in China). They examined the constellation Pisces, which found a galaxy J0100 + 2802. They are interested in a red hue, who spoke about the long distance, as well as the intensity of the radiation of the quasar in the center of the galaxy. The scientists decided to conduct surveillance and to find the distance to the quasar, as well as its characteristics. It turned out that at the present time, we see the quasar as it was still about 12.8 billion years ago (it is believed that it is - a little less than a billion years after the Big Bang). Quasar is also very bright - brighter than 420 trillion Suns.

The mass of the supermassive black hole - about 12 billion solar masses. So how could arise such large black holes, given that, focusing on modern scientific theory, the formation of J0100 + 2802 would take place only a few hundred million years after the so-called reionization era? Modern theories do not give answers - proceeding from them, even in the most efficient absorption of matter of time growth was not.
