This image of the Event Horizon Telescope project will show the event horizon of the supermassive black hole at the centre of the galaxy M87.
If you take a dive into a black hole (something which we don’t recommend it), you’d probably find in a singularity, or an infinitely small and dense point in the center. Or that’s what scientists have previously thought.
But now, a few scientists suggest that some of the black holes are not black holes at all. Instead, they have weird objects full of dark energy, the mysterious force thought to be pushing at the outer limits of the universe, which makes it an ever-increasing rate of speed.

“If what we’re thinking is that black holes are actually objects that has no singularities, the accelerating expansion of the universe is a natural consequence of Einstein’s general theory of relativity,” said Kevin Croker, an astrophysicist at the University of Hawaii at Mānoa.
Croker, a co-worker and describe the idea in a new study, published online Aug. 28, in the Astrophysical Journal. If they are correct, and the singularity at the centre of a black hole, it would be replaced by a strange energy and threw them out of each other, that it is possible to have a revolution in the way we think about a dense object.
The duo had to find out what is inside a black hole. Croker, and Joel Weiner, professor emeritus of mathematics at the same university, they were looking to the Friedmann equations which are simplified by Einstein’s general theory of relativity. (The theory of relativity describes how mass and energy warp space-time.) Scientists use the Friedmann equations describing the expansion of the universe is, in part, because the math is simpler than Einstein’s-body equations to describe relativity. The team found that, in order to be able to write the Friedmann equations, ultradense, and remote regions of space, such as neutron stars and black holes, and had to be treated in the same mathematical way as for all other areas. Previously, cosmologists believe that it is reasonable to disregard the internal details of ultradense and isolated regions, such as the inside of a black hole.
“We’re leaving, there’s only one way to construct such equations is] correct,” Croker told Live Science. “And if you do that one thing, and that is the right way to do it, you will find a number of interesting things.”
The new findings suggest that dark energy is the accelerating expansion of the universe may also be included in this alternative to black holes and dark matter. The researchers found it in the fields of mathematics, after they had been restored to the way of writing the Friedmann equations. In a follow-up paper submitted to The Astrophysical Journal and are posted in September. 7, in the preprint journal arXiv, and they showed that the use of these alternatives to black holes and dark matter, the so-called Generic Objects, of the Dark Energy Balls), it may also help to explain some peculiarities in gravitational-wave observations of 2016.
The mathematics of the Friedmann equations, showing that, after a certain period of time, these ultradense objects in the weight is simply due to the expansion of the universe, even if there is no material for them to consume. As light travels through expanding space, energy, and loses an effect known as red shift — important to losing weight, however, if the space is larger. The effect is usually so small that it can’t be seen. But in the ultradense material is very strong pressure, which is known as relativistic material, its effect will be felt. Dark energy is extremely relativistic, and the pressure works the opposite of normal matter and light, so the objects made of it (such as the hypothetical Balls of weight over time.
“The light is a bit of a weird thing. Acting against instinct, in many ways,” Croker said. “People didn’t expect this sort of behavior can also be seen in the other objects. However, we have to show that, yes, you can see it in a different ” object,” namely, in the Balls.
Balls were first introduced as a concept in the mid-1960s, however, the mathematics is to support them, it was just working the other day. But it turns out that these strange objects could provide a simple explanation for the observed black hole mergers. In 2016, the members of the Laser Interferometer Gravitational-Wave Observatory (LIGO)-Virgo collaboration announced the first observation of a black hole merger, however, the calculated masses of the so-called black holes and it was unexpected — experts had expected that the masses of the two lots will be higher or lower.
But the Balls, as opposed to the traditional ” black holes and weight at the time. If two of the Balls that had formed in the early universe, and, eventually, crashed into the side of the time they collided, they grew larger than that of the typical black holes at their centers. By this point, the Balls’ masses would be equal to the mass of the fragments in the collision has been detected by LIGO-Virgo. Instead of thinking of a very specific situation that led to the merger of Balls, it would be able to provide a simple solution to this is to explain the observations.
Not all scientists are convinced, though. The description of these objects, it is “counter-intuitive and hard to swallow,” Vitor Cardoso, a professor of physics at the Instituto Superior Técnico in Lisbon, Portugal, who was not involved in the study, told Science in an e-mail. But, he added, “I’m in love with the idea of finding alternatives to a black hole — it forces us to reinforce the black-hole paradigm. Also, sometimes it can be hard to find, and if we don’t look for them.”
