Breakthrough wormhole simulation may unite quantum physics and general relativity

Posted by in categories: cosmology, quantum physics

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

NASA uses a climate simulation supercomputer to better understand black hole jets

Posted by in categories: climatology, cosmology, evolution, particle physics, supercomputing

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.

In a first, scientists create a holographic wormhole and sent a message through it

Posted by in categories: cosmology, quantum physics

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.

There must be a singularity at each black hole’s center

Posted by in categories: cosmology, singularity

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.

Another Universe Existed Before Ours — And Energy From It Is Coming Out Of Black Holes

Posted by in category: cosmology

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 Say Stuff Might Have Been Happening Before the Big Bang

Posted by in category: cosmology

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.

Wrinkles left over from the Big Bang may have magnetized the universe

Posted by in category: cosmology

Researchers have proposed what’s perhaps the most exotic explanation to date for the source of the universe’s seed magnetic field: cosmic strings.
