What can be done from 910,000,000,000,000,000 tons of calcium from the Earth's crust?<br /><br />Take, for example, the Great Wall of China, which weighs approximately 558 million tons, and extend this wall using calcium from the Earth's crust, we get 44,000 walls to Pluto. <br />But if you swing to the nearest star, then this amount of calcium can be used to build 8 walls. <br />But to the star Vega, you can build one wall.<br />Theoretically, of course.<br /><br />#interesting #Calciumearth #Calciuminteresting #Earthchemistry #Earthcrust #Earthgeology #calcium #chemistry #earth #earthscience #geology #science
