What happens when black holes die?

What is arguably his most important contribution to science, Stephen Hawking He suggested that black holes could leak a form of radiation that causes them to gradually recede, eventually ending their lives in a massive explosion event. This radiation, later called “Hawking radiation”, inadvertently causes a problem at the junction general relativity And the Quantum … Read more

Shock waves left over from deep space baffle scientists

Andrey OnufrienkoGetty Images far galaxy The block boasts an unusual retrograde shock phenomenon. Galaxies contain thousands of galaxies and tons plasma in motion. The background shock wave may be caused by overlapping collisions between subgroups. Scientists from the University of Western Australia and Italy’s University of Bologna have been studying a group of very distant … Read more

An ancient source of oxygen for life hidden deep in the Earth’s crust

The researchers were able to simulate some of the basic conditions for fracturing subsurface rocks using flasks in the laboratory. The rocks representing the oceanic and continental crust were crushed under nitrogen, added to deoxygenated water, and then heated.

How can nuclear fusion use less energy

For decades, if you asked a fusion scientist to photograph a fusion reactor, they would probably tell you about a tokamak. It is a chamber the size of a large room, shaped like a hollow cake. Physicists fill its interior with a not-so-tasty jam of superheated plasma. They then surround it with magnets in hopes … Read more

Strong Force Strength – It accounts for 99% of the normal mass in the universe

The new experiments sharpen a previously unmeasured area of ​​strong force coupling, a quantity that supports theories that account for 99 percent of the normal mass in the universe. Thomas Jefferson National Laboratory’s experiments focus on a previously unmeasured region of strong force coupling, a quantity that supports theories that account for 99% of the … Read more

Do ‘return universes’ have a beginning?

Credit: Pixabay/CC0 Public Domain In an effort to understand the nature of the universe, some theorists suggest that the universe is expanding and contracting in endless cycles. Since this behavior is supposed to be permanent, Universe It should have neither beginning nor end – only eternal cycles of growth and contraction that extend forever into … Read more

No dark matter halos

The dwarf galaxy NGC1427A flies through the Fornax galaxy cluster and undergoes turbulence that would not have been possible if this galaxy were surrounded by a heavy, stretching dark matter halo, as required by standard cosmology. Credit: ESO According to the Standard Model of cosmology, the vast majority of galaxies are surrounded by a halo … Read more
