My biggest fandoms are Avatar: the Last Airbender, Doctor Who, Ophan Black,Sherlock, and One Direction. I reblog the weirdest things that are highly unexpected at times. Just as a warning: THE MOST RANDOM CRAP WILL BE SEEN HERE! You have been warned

According to the Law of Conservation of Mass, matter can neither be created nor destroyed. This means that all atoms are recycled over time. Which in turn means that our own atoms are ancient as well. One’s skin could have carbon in it from a meteorite or from a trilobite thousands of years old, and your blood could contain hydrogen from earth’s original atmosphere.
