We are Made of Star Stuff



The nitrogen in our DNA, the calcium in our teeth, the wholesale NBA jerseys iron in our blood, the carbon in our apple pies were made Melanson in the interiors of collapsing stars. We are made of star stuff.

Carl Sagan

Carl Sagan was, as always, correct. We humans are all made from stars. That may sound like a pop music lyric, or something a hippie would say, but it’s absolutely true. Here’s the logic:

Star fuel

Stars’ (like our sun) run on fuel, just like our cars run on gasoline. Star fuel is made by aprendidas combining atoms. The extremely hot temperatures inside of a star make atoms move around very wildly and quickly! The atoms move so quickly, that they smash into each other cheap NFL jerseys and combine to form heavier elements. This process is called nuclear fusion. Hydrogen atoms combine to cheap NBA jerseys form Helium cheap NFL jerseys atoms, Helium atoms Концертная combine to form Lithium, and so on.

You see, since the very beginning of the universe, stars have been continually born, died, and reborn again. This endless cycle is what created everything we know in our universe. And, since stars have been around for over 13 billion years, compared to humans’ 200 thousand year existence, they are like our ancestors!
