A new study suggests that hypothetical stars may be the densest objects in the universe that don’t turn into full-fledged black holes.
According to a new theory, elusive hypothetical stars could look like a black hole and even have the properties of a black hole. But this object does not have an event horizon, that is, a boundary where even light cannot leave a black hole. But the gravitational force of these stars can be overcome with a lot of effort, according to Live Science.

No one has been able to find the densest object in space that could exist in the universe, and that also did not turn into a black hole. This hypothetical object is called Buchdal’s star, and many scientists even debate whether they can exist. But Indian physicist Naresh Dadhich may have discovered a new feature that could help answer the question of whether Buchdal stars exist.
Black holes, white dwarfs and neutron stars
Astronomers now know how black holes form. They are formed when massive stars lose their outer layers as a result of the explosion and their cores are compressed forever. But astronomers still don’t know how much the core of such a star might shrink to avoid turning into a black hole. It is now known that some stars turn into white dwarfs or neutron stars rather than black holes. At the same time, the first is the size of our Earth, and the second is the size of a small city. However, is there a smaller object that does not turn into a black hole despite the highest density? There are only theoretical answers to this question, and they lead us to the fact that it is possible for the so-called Buchdal stars to exist in space.
black hole simulators
As early as 1959, physicist Hans Adolf Buchdal was studying how a maximally compressed star could behave to form a perfect globular cluster of matter. Scientists have suggested that the compression of such a star will occur at a certain limit, which will not allow it to turn into a black hole and at the same time exist in the universe. Thus, the densest object that has not turned into a black hole in space is obtained. However, if the compression continues further, this limit will be exceeded and the object will become a black hole.
Many theorists are trying to figure out how to detect this hypothetical object, called Buchdal’s star. Among them is the Indian physicist Naresh Dadhich. The scientist calls these elusive stars, which no one has yet discovered, as black hole simulators because they have properties similar to black holes.
Characteristic of the Budhalya star
As part of his research, Dadhic studied what could happen to the energy of a hypothetical star that begins to collapse towards Buchdal’s star. The scientist believes that when a star approaches the Budhal limit during compression, the ratio of the amount of energy that scientists are familiar with appears – the total kinetic energy is equal to half the potential energy. This relationship holds true for many situations in astronomy where the gravitational force is in balance with other forces. This means that Buchdal’s star could theoretically exist as a stable object with known, well-studied properties.
These black hole simulators don’t have an event horizon, Dadhich says, meaning they can be used to theoretically learn what’s going on inside full-fledged black holes.
“The event horizon of a black hole doesn’t allow us to know what’s inside it. But if you study the Buchdal star and understand its structure, you can learn what the internal structure of a black hole looks like,” Dadhic says.
But now all that remains is to discover Buchdal’s star. But until now, scientists do not know of such a mechanism that could cause the appearance of matter to be compressed. Dadhich believes that if new properties of these hypothetical objects are discovered, they could provide clues on how to find them.
