Best of Last Week—Earthquakes may form gold nuggets, IQ limits …
网页2024年9月9日 · It was a good week for geology research as a team of geologists at Monash University found evidence that the electricity generated by earthquakes might be the secret behind the formation of giant gold nuggets around the globe. And a team of tectonics specialists from China and Australia created an animation showing 1.8 billion years of Earth's land mass changes due to tectonic plate shifting.
网页A circular pee-conomy. Doing this is quite easy: you just fill a urine dryer with an alkalising agent, connect it to your toilet, pee as usual and the urine is converted into dried fertilizer. A smart design could even make the dryer fit below the toilet so it doesn't take up a lot of bathroom space. While electricity would be needed for ...
网页Compression and expansion. Physicists' current understanding of spacetime comes from Albert Einstein's theory of General Relativity. General Relativity states that space and time are fused and that nothing can travel faster than the speed of light. General relativity also describes how mass and energy warp spacetime—hefty objects like stars ...
Dire wolves went extinct 13,000 years ago but thanks to new …
网页2021年1月14日 · Thanks to the hit television series Game of Thrones, the dire wolf has gained a near-mythical status. But it was a real animal that roamed the Americas for at least 250,000 years, until it became extinct towards the end of the last ice age around 13,000 years ago. While in popular culture the dire wolf is portrayed as a giant predator hunting in snow-covered, northern landscapes, most ...
Schrödinger's cat explained - Science X
网页2020年6月17日 · In 1935, E. Schrödinger proposed his well-known cat thought experiment suggesting, but not explaining, how a measurement transforms the probable states of an atom into the actual state of a cat (alive or dead). Rather than applying quantum mechanics (the previous approach usually taken), I offer an out-of-the-box, logically consistent explanation using metrology (the science of physical ...
The Moon's top layer alone has enough oxygen to sustain 8 billion ...
网页2021年11月11日 · Now let's assume the average depth of regolith on the Moon is about ten meters, and that we can extract all of the oxygen from this. That means the top ten meters of the Moon's surface would provide enough oxygen to support all eight billion people on Earth for somewhere around 100,000 years. This would also depend on …
Why is there water on Earth? - Science X
网页2021年2月12日 · While water represents less than 0.5% of the mass of the Earth, it is key to the evolution of the planet itself and to life at its surface. In the early solar system, there was a lot of hydrogen, mainly in the form of dihydrogen gas (H 2), or bonded with oxygen atoms to form water (H 2 O). However, Earth and the other rocky planets (Mercury, Venus, and Mars) formed near the Sun, where it was ...
