Enlarge In theoretical physics you can have different planes that behave like black holes and they are called black branes. When black branes are folded into multiple dimensions they form a ‘blackfold’, which new research shows has a relationship between gravity and fluid mechanics and solid-state physics.

New knowledge about the remarkable properties of black holes

December 11, 2012

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.
