A Big Bang of sorts...

The massive explosions of the universe's original super-stars is thought to have made the universe a more interesting place. Prior to these super-stars, the universe was basically a giant cloud of hydrogen. As the hydrogen began to amass, it fell into large bright fusion reactions - the first stars. These stars were so big, they only lasted a few million years (as opposed to the ten billion year lifespan of our star.)

They exploded with a force that is almost inconceivable, and the giant explosions caused the heavier elements to form. All of us living are made out of these bits of kaboomed super-star, the remnants of these earliest explosions.
