Strange mathematical term changes our entire view of black holes

Posted by in categories: cosmology, mathematics, physics

Black holes are getting weirder by the day. When scientists first confirmed the behemoths existed back in the 1970s, we thought they were pretty simple, inert corpses. Then, famed physicist Stephen Hawking discovered that black holes aren’t exactly black and they actually emit heat. And now, a pair of physicists has realized that the sort-of-dark objects also exert a pressure on their surroundings.

The finding that such simple, non-rotating “black holes have a pressure as well as a temperature is even more exciting given that it was a total surprise,” co-author Xavier Calmet, a professor of physics at the University of Sussex in England, said in a statement.

A Particle Physics Experiment Might Have Directly Observed Dark Energy

Posted by in categories: cosmology, particle physics

In a new study, a team of researchers proposed that Dark Matter detectors could also search for the elusive force that is causing our Universe to expand (Dark Energy)!


About 25 years ago, astrophysicists noticed something very interesting about the Universe. The fact that it was in a state of expansion had been known since the 1920s, thanks to the observation of Edwin Hubble. But thanks to the observations astronomers were making with the space observatory that bore his name (the Hubble Space Telescope), they began to notice how the rate of cosmic expansion was getting faster!

Are we living in a baby universe that looks like a black hole to outsiders?

Posted by in categories: cosmology, physics

A new paper takes a deep dive into primordial black holes that were formed as a part of the early universe when there were still no stars or galaxies. Such black holes could account for strange cosmic possibilities, including baby universes and major features of the current state of the cosmos like dark matter.

To study the exotic primordial black holes (PBHs), physicists employed the Hyper Suprime-Cam (HSC) of the huge 8.2m Subaru Telescope operating near the 4,200 meter summit of Mt. Mauna Kea in Hawaii. This enormous digital camera can produce images of the entire Andromeda galaxy every few minutes, helping scientists observe one hundred million stars in one go.

A strange void found in space could solve an enduring mystery

Posted by in category: cosmology

This void spans across nearly 500 light years.


Although space is vast, it mostly teems with gas, dust, rocky objects, or stars. But this region wedged between the star-forming clouds was bare, puzzling the astronomers.

NASA Turned a Star’s Corpse into Sound — and It’s Magical.


We all know that there’s no sound in space. However, one project from NASA is turning that fact on its head by transforming images of space objects into beautiful music.

“X-Ray Magnifying Glass” Provides Unprecedented Look at Black Hole in the Early Universe

Posted by in categories: cosmology, government

This magnifying glass was used to sharpen X-ray images for the first time using NASA

Established in 1,958 the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. It’s vision is “To discover and expand knowledge for the benefit of humanity.”
