#water #antarctica #bigbang #universe #podcast #briankeating #intotheimpossible #science #astronomy #cosmology We take if for granted and it’s essential to all the life we know. It makes up 70% of the surface of the earth and 60% of our bodies. Water. But have you stopped to ponder from where water comes? Incredibly all the water on earth is of extraterrestrial origins. Earth does not “make” any water. All the water on earth now has not changed much in billions of years and the amount we have is almost all there will ever be. Less than 1% of it is readily available for human and animal consumption. Water is perhaps of the most unique compound known. Its hexagonal structure gives it extraordinary properties that support life including the fact that it expands when frozen. All water is not alike. In this video Professor Keating examines water from various sources including Antarctica and the isotopic variety of water known as heavy water or deuterium. He also explains more exotic forms including the stuff of fusion; tritium. We’ll discover how the origin of water is tied to the origin of the univers and the fate of stars. And why water is one of the most common compounds in the universe.
