Scientists Have Finally Sampled the Most Abundant Material On Earth
rossgneumann writes: The most abundant material on Earth didn't have a name, and, in fact, hadn't been seen — until now. For the first time ever, scientists have gotten their hands on a sample of bridgmanite, a mineral that is believed to make up more than a third of the volume of the Earth. In a new paper published in Science late last week, Oliver Tschauner of the University of Nevada, Las Vegas, and his team describe bridgmanite for the first time.
Compared to the volume of the rest of the planet, much of it consisting of, you guessed it, bridgmanite, water is a very thin film on the surface....water is about 0.02% of the total earths' mass
Water is in fact, therefore, pretty scarce on Earth.
That's like arguing the material a balloon is made of is scarce on a balloon. Its true that there's not much of it in the total volume of a balloon. But it still makes up pretty much 100% of the surface area ON a balloon.
Similarly bridgmanite is pretty rare on the surface, even if it is the most common by far when you start looking further down.
I donno, lately I'm finding more tech news and geek/fandom interests by browsing reddit/all than I find on Slashdot.
Do not look into laser with remaining eye.
