It's a technique.ДЄssociate Professor Steinhower and his colleagues cooled the gas containing about 8,000 rubidium atoms to near absolute zero and irradiated it with a laser to fix the position of the atoms. A black hole is a celestial body that cannot escape even light, but an acoustic black hole is an experiment that focuses on sounds that are similar in nature to light as waves and creates a 'space where sound cannot escape' to clarify the properties of black holes.

The 'pseudo-black hole' used by Associate Professor Steinhower in a series of experiments is called a '(PDF file) acoustic black hole' that uses sound instead of light. Associate Professor Steinhower has been conducting research on confirming Hawking radiation by pseudo-black holes since 2009, and in 2016 published a treatise stating that 'Hawking radiation was confirmed.' ' This prediction later came to be called 'Hawking radiation' in the name of the doctor, and pioneered a new academic field called quantum cosmology.ДЄ new study by Associate Professor Jeff Steinhower of Technion-Israel Institute of Technology confirmed the 'steadiness' that radiation from pseudo-black holes generated in the laboratory is invariant with time. Particles annihilate with other virtual particles and have positive energy, which means that black holes get negative energy and at the same time emit particles with positive energy. Hawking explained that virtual particles have negative energy, 'It is synonymous with having negative energy if a black hole captures a virtual particle, and the virtual particle on the side that was not captured. Consideration about the case that has been done. Hawking thought that virtual particles would be pair-produced near the 'event horizon ' where even the light inherent in the black hole would be captured, and only one of them would cross the event horizon. 'ДЄccording to the uncertainty principle in quantum mechanics, a vacuum is not a space that is truly empty, but a space in which virtual particles repeat pair production and pair annihilation. Hawking said in 1974, 'Black holes are named black in the sense of'no radiation', but when the quantum effect is taken into account, they should actually be doing thermal radiation, and that radiation is in time. Lab-grown black hole analog behaves just like Stephen Hawking said it would | Live ScienceДr. Stephen Hawking, who was called a 'wheelchair physicist,' confirmed the 'Hawking radiation ' predicted in 1974 in a pseudo-black hole. In other words, we would take into account that the analogue black hole is composed of point-like atoms.20:00:00 Research results that confirmed 'Hawking radiation' in a pseudo black holeДЄn Israeli research team has announced that Dr. вЂњOur new long-term goal,вЂќ Steinhauer concluded, вЂњis to see what happens when one goes beyond the approximations used by Hawking, in which the Hawking radiation is quantum, but space-time is classical. This is likely due to the development of stimulated radiation following the formation of the inner horizon, the physicists explained in the journal Nature Physics. After a certain time, the radiation emitted by the system began to intensify. The experiments also revealed new insights that werenвЂ™t predicted during HawkingвЂ™s lifetime. This gives very significant experimental support to HawkingвЂ™s analysis, which gets experimental approval for the first time in JeffвЂ™s experiments.вЂќ вЂњJeff measures stationary Hawking radiation emitted from a sonic black hole, in agreement with HawkingвЂ™s theoretical prediction. Amos Ori, a general relativity and black hole expert at the Technion Physics Department, said in a statement.

Steinhauer are of great importance and interest,вЂќ Prof. Luckily for them, their patience paid off. It took 97,000 iterations of this experiment over 124 consecutive days for the physicists led by Steinhauer to confirm Hawking radiation. YouвЂ™d be in a more вЂnormalвЂ™ environment, as the pull of gravity would be lower, so you wouldnвЂ™t feel it anymore.вЂќ The analog black hole created by the researchers. вЂњIf you fall through the inner horizon, then youвЂ™re still stuck in the black hole, but at least you donвЂ™t feel the weird physics of being in a black hole.

Jeff Steinhauer of TechnionвЂ™s Physics Department said in a statement. вЂњEssentially, the event horizon is a black holeвЂ™s outer sphere, and inside it, thereвЂ™s a small sphere called the inner horizon,вЂќ Prof. Just like in a black hole that has trapped light particles crossing the event horizon, the phonon cannot return to the other side of the sonic black holeвЂ™s event horizon. Phonons in the faster half of the gas flow, beyond the event horizon, are trapped by the speed of the flowing gas. Rather than pairs of photons spontaneously forming in the gas, the researchers were looking for pairs of phonons - quantum sound wave particles.
