The researchers' lab-grown black hole was made of a flowing gas of approximately 8,000 rubidium atoms cooled to nearly absolute zero and held in place by a laser beam. They created a mysterious state of matter, known as a Bose-Einstein Condensate (BEC), which allows thousands of atoms to act together in unison as though they were a single atom.
Using a second laser beam, the team created a cliff of potential energy, which caused the gas to flow like water rushing down a waterfall, thereby creating an event horizon where one half of the gas was flowing faster than the speed of sound, the other half slower. In this experiment, the team was looking for pairs of phonons, or quantum sounds waves, instead of pairs of photons, spontaneously forming in the gas.
A phonon on the slower half could travel against the flow of gas, away from the cliff, while the phonon on the faster half became trapped by the speed of the supersonic flowing gas...
Once they found these phonon pairs, the researchers had to confirm whether they were correlated and if the Hawking radiation remained constant over time (if it was stationary). That process was tricky because every time they took a picture of their black hole, it was destroyed by the heat created in the process. So the team repeated their experiment 97,000 times, taking more than 124 days of continuous measurements in order to find the correlations. In the end, their patience paid off.

if you say so...
That experiment must’ve sucked the brains right out of them.
They only love their collider.
Now prove to us that is what’s happening out in space?
Doing something on earth doesn’t mean it’s happening that way throughout the Universe.
Once they can establish a method to replicate the experiment and outcome, they will be looking for more Biden votes....bet on it!!
Leonard and Sheldon said this would happen.
How much energy does it take to cool something to near-absolute zero?
Black Holes Matter. I thought so.
They keep messing around with nature like this and, yes, one day they’ll ‘succeed’ in creating a real black hole that will quickly grow and swallow up the planet. Of course, they say that cannot possibly happen, but...
I would be far more concerned about "gain in function" research on a virus escaping into the wild.
“That process was tricky”
Not to a professional equipped with a catchers mitt and a can of flex steel.
THE JOLLY, CANDY-LIKE BUTTON!!!
And the framus intersects with the ramistan approximately at the paternostra.
Now if only Hawking had lived a few more years, he could’ve gotten that Nobel...
Its called math. Math works on earth and the same math works in space.
