The breakthrough could suggest a way to study ‘quantum gravity,’ the missing link between quantum physics and Einstein’s general relativity in the lab.

The specific event they observed and analyzed is so rare that it has only been seen three other times throughout history.
NASA’s Discover supercomputer simulated the extreme conditions of the distant cosmos.
A team of scientists from NASA’s Goddard Space Flight Center used the U.S. space agency’s Center for Climate Simulation (NCCS) Discover supercomputer to run 100 simulations of jets emerging from supermassive black holes.
The scientists set out to better understand these jets — massive beams of energetic particles shooting out into the cosmos — as they play a crucial role in the evolution of the universe.
This could help us probe into the lesser-known field of quantum gravity.
A collaborative team of researchers in the U.S. created a holographic wormhole and sent a message through it. This is the first known report of a quantum simulation of a holographic wormhole on a quantum processor.
However, the two theories are fundamentally incompatible and the holographic principle is a guide that can help us combine the two.

Einstein’s theory of general relativity helps us to understand the physical world such as astronomical objects with high energies or matter densities. Quantum mechanics on the other hand, describes matter at atomic and subatomic scales.
We’ll never be able to extract any information about what’s inside a black hole’s event horizon. Here’s why a singularity is inevitable.
An older universe existed before the Big Bang, and proof for its existence can still be found in black holes, according to a Nobel Prize-winning physicist. Sir Roger Penrose made the assertion after receiving the award for advances in Einstein’s general theory of relativity and proof of black hole existence. Sir Roger contends that inexplicable regions of electromagnetic radiation in the sky, known as ‘Hawking Points,’ represent vestiges of an earlier universe.
Scientists have made it possible to listen to the light echoes of a black hole by turning astronomical data into souns.
An international team of researchers are suggesting that our understanding of the origins of our universe may need some updates.
As detailed in a new paper published this week in The Astrophysical Journal Letters, they say the universe may have begun with a “Big Bounce” rather than a Big Bang.
In other words, the cosmos may have been born following of the end of a previous cosmological phase — a bounce — and not the result of space-time inflating exponentially into existence.
Researchers have proposed what’s perhaps the most exotic explanation to date for the source of the universe’s seed magnetic field: cosmic strings.
