Mars Once Had So Much Water, It Could Have Been An Ocean World, Scientists Say

Posted by in category: space

Today, Mars is colloquially known as the ‘Red Planet’ on account of how its dry, dusty landscape is rich in iron oxide (aka. ‘rust’). In addition, the atmosphere is extremely thin and cold, and no water can exist on the surface in any form other than ice.

But as the Martian landscape and other lines of evidence attest, Mars was once a very different place, with a warmer, denser atmosphere and flowing water on its surface.

For years, scientists have attempted to determine how long natural bodies existed on Mars and whether or not they were intermittent or persistent.

Completing Einstein’s Theories — A Particle Physics Breakthrough

Posted by in categories: information science, particle physics

Osaka University researchers show the relativistic contraction of an electric field produced by fast-moving charged particles, as predicted by Einstein’s theory, which can help improve radiation and particle physics research.

Over a century ago, one of the most renowned modern physicists, Albert Einstein, proposed the ground-breaking theory of special relativity. Most of everything we know about the universe is based on this theory, however, a portion of it has not been experimentally demonstrated until now. Scientists from Osaka University’s Institute of Laser Engineering utilized ultrafast electro-optic measurements for the first time to visualize the contraction of the electric field surrounding an electron beam traveling at near the speed of light and demonstrate the generation process.

According to Einstein’s theory of special relativity, one must use a “Lorentz transformation” that combines space and time coordinates in order to accurately describe the motion of objects passing an observer at speeds near the speed of light. He was able to explain how these transformations resulted in self-consistent equations for electric and magnetic fields.

The rover is expected to be larger than the two China-operated rovers on the Moon earlier. Wu claimed that nuclear energy could also be used to power the hopper, a machine intended to lift off from the lunar surface numerous times and bounce in and out of a crater’s constantly shadowed section in search of water.

Nuclear energy will support the station’s communications facilities to maintain communication with Earth and power the station’s communications systems. It will also stay connected to the Earth and relay signals between the Earth, Mars, and deep space. China has also announced its desire to explore deep space.

Quantum Physics Axed Materialism. Many Hope the World Won’t Know

Posted by in categories: neuroscience, quantum physics

Quantum mechanics, which developed in the early 20th century, has been a serious blow to materialism.

There is no way to make sense of it if immaterial entities like information, observation, or the mind are not real. Theoretical physicist Sabine Hossenfelder struggles against the effects of this fact.

High-Laser-Energy Shot Puts NIF Back on Track Toward Ignition

Posted by in categories: nuclear energy, physics, security

Someone else posted about this, but this is from LLNL. I love what they do, and Twitter reminded me of the many Photonics shares I have. This is cool, and Ill post more links.

A record high-laser-energy NIF target shot on Sept. 19 produced about 1.2 million joules of fusion energy yield. Compared with the groundbreaking 1.35-megajoule (MJ) experiment of Aug. 8, 2021, this experiment used higher laser energy and a modified experimental design.
