Is a black hole already found?

Scientists strongly believe that black holes really exist. Albert Einstein’s general theory of relativity predicted the existence of such objects back in 1917, and over the past decades, astronomers have found plenty of evidence of their presence in many areas of outer space.
More than 5 objects are known, which probably include black holes. However, there is only indirect evidence, but there is no conclusive evidence. The most likely candidate for black holes is the X-ray source Cygnus X-1, discovered in the early 1970s in X-binary systems. The mass of the source in this system, which can be estimated from the observed speed of the optical star in its orbit and Kepler’s laws, exceeds the limiting mass for a neutron star. The Chandra X-ray Observatory found in several galaxies with a high rate Continue reading

Inflationary universe

In addition to the question of the origin of the universe, modern cosmologists face a number of other problems. So that the standard theory of the big bang could predict the distribution of matter that we observe, its initial state must be characterized by a very high degree of organization. The question immediately arises: how could such a structure be formed? The physicist A. Gut from the Massachusetts Institute of Technology proposed his version of the Big Bang theory, which explains the spontaneous emergence of this organization, eliminating the need to artificially introduce exact parameters into the equations describing the initial state of the Universe. His model was called the “inflationary universe.” Its Continue reading
