AllatRa by Anastasia Novykh
The problem is that all modern theories, from Einstein’s general theory of relativity to
laws of thermodynamics, are based on interactions of the “visible matter” or on its
logically predictable behaviour. Although there are many strange things here as well.
Let’s take, for example, black holes in the Universe — these mysterious objects,
unexplored by contemporary science, which absorb matter. Yet, before we look into
these things and also shed light on the issue of the objects the formation of which is
directly linked to black holes, I would like to ask you first: what do you know about
black holes?
Anastasia: Well, not as much as I would like to… Black holes are invisible to the
outside observer because they prevent both light and any other radiation known to
science, as well as objects, from escaping. At present, attempts are made to identify
black holes using only indirect signs, by means of studying their interaction with the
surrounding matter... The black hole is believed to curve the geometry of spacetime
around itself.
At the current stage of development of astrophysics, it is assumed that the black hole is
some localised area of outer space formed by unrestricted gravitational compression of
massive celestial bodies. As I understand, this is something like a gravitational grave in
which everything disappears once it gets inside. The boundary of such an area is called
the event horizon and its radius, the gravitation radius. It is considered that the latter
directly depends on the amount of matter pulled into the hole. As the mass of the black
hole increases, its size also increases linearly, i.e. its radius increases. The size of this
object may vary…
The modern theory of stellar evolution regards the formation of black holes as the result
of collapse of massive and supermassive stars. As I see it, when nuclear fuel runs low
and thermonuclear reactions terminate inside a star, high temperature and pressure,
which prevented the contraction of the star, now decrease under the influence of its own
gravity. If the mass of a star is lower than three masses of the Sun, the star won’t turn
into a black hole, but it will just become a neutron star or a white dwarf. And if the mass
of the star is more than three masses of the Sun, scientists believe that a catastrophic
collapse is unavoidable. Its entire matter will rapidly cross the event horizon, and the
star will become a black hole…
