We
are all made of stardust. It sounds like a line from a poem, but there is some
solid science behind this statement. Almost every element on Earth was formed
at the heart of a star. Everything we are and everything in the universe and on
Earth originated from stardust, and it continually floats through us even
today. It directly connects us to the universe, rebuilding our bodies over and
again over our lifetimes.
We really don’t realize how transient we are. Our
bodies are made of fragments of stars and massive explosions in the galaxies.
All the material in our bodies originates with that residual stardust, and it
finds its way into plants, and from there into the nutrients that we need for
everything we do think, move, grow. And every few years , our bodies are newly
created. Our bodies are never static. We're dynamic beings, and we have to be
dynamic to remain alive. This is not just true for us humans. It's true for all
living things.
We have stuff in us as old as the universe, and
then some stuff that landed here maybe only a hundred years ago. And all of
that mixes in our bodies. To keep alive, our cells have to divide and grow. Very
little of our physical bodies lasts for more than a few years. we perceive
ourselves when we look into the mirror. But we're not fixed at all. We're more
like a pattern or a process. And it was the briefness of the body and the flow
of energy and matter needed to counter that transience that led us to explore
our interconnect with the universe.
History began in outer space. Take salt. What
we usually mean by kitchen salt. It has two chemicals. Where did they come
from? They were formed inside stars that exploded billions of years ago and at
some point, found their way onto the Earth.
We age because we
lose the balance between cell deaths and regeneration. That's what we see in
the mirror when we age over time. We're literally not what were a few years
ago, and not just because of the way we think. Everything around us does this.
Nature is not outside us. We are nature.
Our death marks another remarkable journey , we
are again transforming into dust , in turn we will be part of some others, may
be in a plant , another microbe, another element All again back to stardust ........ the journey continues
