Black holes are surrounded by many mysteries, but now researchers from the Niels Bohr Institute, among others, have come up with new groundbreaking theories that can explain several of their properties. The research shows that black holes have properties that resemble the dynamics of both solids and liquids. The results are published in the prestigious scientific journal, Physical Review Letters.
Black holes are extremely compact objects in the universe. They are so compact that they generate an incredibly strong gravitational pull and everything that comes near them is swallowed up. Not even light can escape, so light that hits a black hole will not be reflected, but will be entirely absorbed, as a result, they cannot be seen and we call them black holes.
“But black holes are not completely black, because we know that they emit radiation and there are indications that the radiation is thermal, i.e. it has a temperature,” explains Niels Obers, a professor of theoretical particle physics and cosmology at the Niels Bohr Institute at the University of Copenhagen.
Multiple dimensions in black holes
Researchers know that the black holes are very compact, but they do not know what their quantum properties are. Niels Obers works with theoretical modelling to better understand the physics of black holes. He explains that you can look at a black hole like a particle. A particle has in principle no dimensions. It is a point. If you give a particle an extra dimension, it becomes a string. If you give the string an extra dimension, it becomes a plane. Physicists call such a plane a ‘brane’ (the word ‘brane’ is related to ‘membrane’ from the biological world).
“In string theory, you can have different branes, including planes that behave like black holes, which we call black branes. The black branes are thermal, that is to say, they have a temperature and are dynamical objects. When black branes are folded into multiple dimensions, they form a ‘blackfold’,” explains Niels Obers, who worked out this new way of looking at black branes with associate professor in theoretical physics at the Niels Bohr Institute, Troels Harmark, back in 2009.
New black brane, blackfold breakthrough
Niels Obers and his two doctoral students Jay Armas and Jakob Gath have now made a new breakthrough in the description of the physics of black holes based on the theories of the black branes and blackfolds,
“The black branes are hydro-dynamic objects, that is to say that they have the properties of a liquid. We have now discovered that black branes also have properties, which can be explained in terms of solids. They can behave like elastic material when we bend them,” explains Jay Armas.
He explains that when the black branes are bent and folded into a blackfold, a so-called piezoelectric effect (electricity that occurs due to pressure) is created. This new effect can be understood as a slightly bent and charged black string with a greater concentration of electric charge on the innermost side in relation to the outermost side. This produces two electrically charged poles on the black strings. Black holes are predicted by Einstein’s theory of gravity. This means that there is a very surprising relationship between gravity and fluid mechanics and solid-state physics.
“With these new theories, we expect to be able to explain other black hole phenomena, and we expect to be able to better understand the physical properties of neutron stars. We also expect to gain a greater understanding of the so-called particle theories, which are, for example, relevant for understanding the quark-gluon-plasma in the primordial universe,” explains Niels Obers.
I like looking through a post that will make men and women think.
Also, thanks for allowing for me to comment!
maybe not one universe to every black hole but a parallel universe equal and opposite of our own and all the matter and energy that is pulled by the hole is dispensed as dark matter and dark energy in the parallel universe as their black holes dispense to our universe pushing everything outward making us perceive it moving outward in an infinite cycle that we can perceive. if we had more senses i think then we could sense more dimensions i don’t know where the number 12 came from in this but its every where even in our calender and in most religion something cannot be created from nothing i think the same can go for an idea a shred of truth in every lie lets say the parallel universe has the opposite but equal set of 6 scenes that we have the only thing is dark matter and dark energy mush some how be converted to the matter and energy you and me are made of for any of it to work. my name is Luke i don’t honestly know a thing. haven’t been to much schooling but have many theories hit me up need feedback [email protected]
It is good that you have now looked at them for what they are, thankyou.
Also, stars do not always get sucked in, as we have witnessed with ones orbital path.
