"Now that we have established that every element in the periodic table aside from hydrogen is essentially stardust, we have to determine how much of our body is made up of this stardust.  If we know how many hydrogen atoms are in our body, then we can say that the rest is stardust. ---

Since stardust atoms are the heavier elements, the percentage of star mass in our body is much more impressive. Most of the hydrogen in our body floats around in the form of water. The human body is about 60% water and hydrogen only accounts for 11% of that water mass. Even though water consists of two hydrogen atoms for every oxygen, hydrogen has much less mass. We can conclude that 93% of the mass in our body is stardust. Just think, long ago someone may have wished upon a star that you are made of."

Eikö maailma olekin uskomaton? Kuulin biisin, jossa laulettiin: "we are stardust", ja se kuulosti oikealta. Mutta en tiennyt että se on tieteellisestikin totta. En ajatellutkaan, että se voisi olla mahdollista. Aivoissani on viime aikoina ilmennyt ihan uutta kiinnostusta tiedettä kohtaan. Pakko myöntää, että se on voi olla kaunista.
