It’s a carbonaceous chondrite - a dark stony material that retains unaltered chemistry from the formation of our Solar System 4.6 billion years ago, and, as such, could give us fresh insights on how the planets came into being.
No, no, wait, just a piece of asphalt. Sorry. Common mistake. Nothing to see hear.
It mught very well be precisely 4.6 billion years old but the idea that this number represents their level of "scientific" knowledge about such things is utter BS! They are not scientists, they are LIARS.They couldn't plot the trajectory of that meteroite back 4.6 seconds!
