The light becomes a liquid that sucks in space-time

By maneuvering in the form of a form of liquid, then use it to simulate space-time, researchers hope to open our understanding of black holes and other exotic things.

Supermassive cosmic goals, such as black holes, very difficult to study directly, but researchers can make useful analogues using laboratory effects. For example, researchers previously simulated space-time – the fabric of our physical fact – Use the worst atomsthen residing it with equals in black holes.

Now, Kévin Fallque In Kastler-Brossel Laboratory (LKB) in Paris and his companions use light to make a good control analog-space analogue.

To do this, they handed the light to a small hole made from a reflective semiconductor material, where it sits on the lapse of material and associated with electricity charges within it. During this process, quotum interactions finally turn off the light a state-like state of the object.

The team can use lasers to control the properties of this liquid and it has the same geometry as space-time. They can also manipulate it to make structures equal to the horizon in a black hole – the edge that can fall but not to return.

Since their strong light-based “can be controlled well, being falque and his partners can only make the banks of the incident less.

They hope to use this unique simulation to test how Hawking Radiationwhich comes from black holes, changing the brightness of the event entority. To get there, however, they need to make their experiment colder and extremely remote, which can inspire the effects of the value inside it.

“Work is an impressive expert experimental experience,” as Juan Ramón Muñoz de Nova In the Complutense University of Madrid, associated with the first measurement of Hawking Radiation in a black hole simulation using ultracld atoms. He said the new experiment opens the door for observations of various odd events, including how black holes flow or “ring”.

Friedrich Koenig At the University of St Andrews in the UK says that the new job shows “a most useful platform”. It may try new ideas about gravity, as well as the mysterious interplay between the effects of gravitational and quantum.

One of the worst results of this experiment we may know that some found black holes true impostorsAs Maxime Jacquetalso in LKB. the first image in a black holeTaken with the movement horizon telescope, certainly as real thing – but looks like a black hole is not the same as one, he says.

Can there be more things shining like black holes, so are they like images, but no event in Entablong? The theoretical work is shown that it is possible, but light-based experiments can be curious with this possibility, as Jacquet.

“We have to be careful. Although we have analogues – there’s a fluid and have a black hole – these things differ,” as the fallque. “But what we do in this experiment is to try and play with the theory used for black holes.”
