After a star has created enough iron, fusion ceases and the hot burning core begins to cool. Up until this point the hot core of the star erupting outwards and preventing gravity from collapsing the star. Now that the star has cooled, the core no longer expands and gravity quickly collapses the star. The star implodes with enough energy to immediately fuse some of the atoms into higher elements like Nickel, Krypton, Gold, Uranium,… etc. This quick and violent implosion releases an enormous amount of energy that explodes the star. This is what we call a supernova! Astrophysicists are still not exactly certain about the details of how a supernova explodes. Hopefully you can figure it out someday! The exploded remains from a supernova travel through out the universe only to someday clump together with other stardust and give birth to a new star. This is the life of our universe. 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. Our body is composed of roughly 7x1027 atoms. That is a lot of atoms! Try writing that number out on a piece of paper: 7 with 27 zeros behind it. We say roughly because if you pluck a hair or pick your nose there might be slightly less. Now it turns out that of those billion billion billion atoms, 4.2x1027 of them are hydrogen. Remember that hydrogen is bigbang dust and not stardust. This leaves 2.8x1027 atoms of stardust. Thus the amount of stardust atoms in our body is 40%. 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.

Even the Ancient Egyptians believed that their deceased kings would return to the stars, where they would enjoy their afterlife. The stars were heavily incorporated into Ancient Egyptian ideologies and everyday life.

It is fun to speculate, but really we have no way of knowing until someone comes back and tells us what happens when we die. It's all about comfort, I mean all the religions, cults and beliefs seem to revolve around offering this comfort as a reward for living the life that they prescribe as "righteous".
My belief is in living a good life, finding pleasure in the happiness of others, content in knowing that whatever happens when I die I can at least say that I tried my best to be a good man.
