There are other branches of contemporary physics which read like hard science fiction novels . In a few branches of science we can find so many extravagant ideas per square meter . And yes, most of the time, these are crazy theories, greguerías armed with equations that, when the time comes, collide with what we call experimental proofs.

But that’s part of its charm .

This week, for example, I came across a very curious pre-impression as to who’s holding this black holes could be super-dense stars, but in which there is no event horizon . At least some of them. The model is interesting because, incidentally, it leads to a whole hypothesis on the composition of dark matter.

Dark stars?

Basically, this work endeavors to take care of one of the fundamental issues of dark openings: singularities. After all, the singularity is nothing more than ” a region of space-time housed in its interior in which one cannot define the value of physical quantities like curvature or other geometric concepts. It’s not only hard to imagine, but complex to explain.

“How could matter collapse at this point?” Critics of the existence of such targets have wondered for years. Finally, Einstein and the consequences of his theories took the cat to the water; however, there are still physicists who are trying to create models of black holes that do not carry the idea of singularity . This is a good example.

Igor Nikitin’s “dark stars” look like black holes on the outside, but on the inside they are not; they contain ” an extremely (but not infinitely) dense core of matter compacted to the littlest conceivable scale ” That is, it has a center the size of ‘Planck’s length’, the littlest measure that bodes well in current physical science. It eliminates the need for singularity, yes, although it’s not clear where it would take us.
