Scientists in the Netherlands built a real black hole in a lab and observed as the enigmatic space object started to glow.
The black hole event horizon was built by a team of physicists from the University of Amsterdam in order to study black hole behavior in a secure, controlled setting.
An event horizon in astrophysics is a line beyond which an observer cannot be impacted by events.
But let’s get back to their discovery: according to a report from Science Alert, the black hole released a rare type of radiation that was first theorized by none other than Stephen Hawking himself.
The team created an analogue of Hawking radiation in the lab with the intention of analysing its characteristics. However, they were taken aback when the analogue started to give off an odd glow.
Due to the black hole’s tearing of spacetime, disturbances in quantum fluctuations result in the creation of particles that are known as hawking radiation.
The radiation appears as a visible glow, which is strange because a black hole’s event horizon is supposed to be a region where nothing can escape except gravity.
One of the strangest and most enigmatic space anomalies is a black hole.
They are an object so dense that, within a certain distance of the black hole’s centre, no known universe-wide velocity can avoid being sucked in, not even travelling faster than light.
The group explained that this only happened when a link in the chain went above the event horizon.
This may suggest that the production of Hawking radiation depends on an entanglement of particles that crosses the event horizon.
The researchers said in their paper, which was published by Physical Review Research, “This can open a venue for exploring fundamental quantum-mechanical aspects alongside gravity and curved spacetimes in various condensed matter settings.”
According to the researchers, the Hawking radiation only manifested as thermal radiation for a specific range of “hop amplitudes” and only in simulations that started by simulating a “flat” type of spacetime.
This implies that Hawking radiation may only emit thermal radiation under specific conditions and may only be possible when there is a change in the space-time warp brought on by gravity.
The Hawking radiation glowing is what matters most, though.
