UNITED STATES (VOP TODAY NEWS) — Pictures of the “shadow” of the black hole in the center of the galaxy M87 prove that these objects cannot be exotic tunnels in the space-time structure, astronomer Heino Falcke said at a press conference at the European Commission in Brussels.
“In the scientific literature there are many alternatives for black holes, and now we have the first opportunity to really test them. For example, now we can say for sure that black holes are not” wormholes”. We can say that our science has become experimental,” – noted astrophysicist.
Falke and his colleagues are working on the Event Horizons Telescope project. where the capacities of the most sensitive radio observatories of the world in Chile, Spain, California, Arizona, Hawaiian islands and even at the South Pole of the Earth were combined.
The main goal of this project, as can be understood from its name, is to “get close” to the event horizon of the black hole Sgr A * located in the center of the Milky Way, and comprehensively study its properties, including photograph its shadow. Similar observations scientists led the galaxy M87, located in the constellation Virgo.
So scientists call a special area of space in the vicinity of a black hole, where a kind of “reflection” of its event horizon will arise due to the effect of gravitational lensing. Compared with the size of the Sgr A * accretion disk, a “donut” of ground matter that the black hole gradually absorbs – it will be very small, but it can be seen.
As the theory of relativity predicts, the shadow of a black hole will look like a dark circle surrounded by a crescent of bright light, but not all scientists agree with this prediction.
Some of them believed that in fact black holes may not be singularities, where matter disappears irrevocably, and so-called “wormholes” are peculiar “tunnels” connecting two points located in different regions of space or time.
Despite their fantastic description, their existence is predicted by the theory of relativity and all its major extensions. EHT observations have resolved these disputes, fully confirming Einstein’s predictions and eliminating the possibility of the existence of wormholes in the centers of galaxies.
“Unfortunately, we did not find any discrepancies with the calculations of the theory of relativity, which, of course, every scientist dreams. In fact, it was enough for me that we just managed to solve this problem. If we saw something completely incomprehensible, then we would have to spend another couple of years checking to see if we had made a mistake while analyzing the data, “continues Falke.
As the scientist noted, more detailed photographs cannot be obtained yet – for this, a telescope is needed, whose dimensions exceed the diameter of the Earth. This task can be solved in the future, when a replacement for the Russian orbital observatory “Spectr-R”, as well as the microwave telescope “Millimetron” or similar foreign devices will be sent into space.
