SCIENCE CONFIRMS THAT NEARLY HALF OF THE HUMAN BODY IS MADE OF STARDUST
BY Buck Rogers,
�The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon
in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.�
~Carl Sagan, Star Stuff Have you ever felt as though some part of
you was not from our galaxy, that somehow you had a physical connection with the cosmos?
A dramatic new study into the origins of galaxies simulated the process by which galaxies are
formed and when stars within them explode. The finding offer strong evidence that nearly
half of the atoms found in the Milky Way are made from residual particles ejected when
far away galaxies go supernova and explode. This includes half of the atoms that make
up the human body.
Carried by intergalactic winds after a galaxy�s death, many of these ejected particles travel
to our solar system from neighboring galaxies, eventually congregating to amass concentrations
of the building blocks of atoms. The bulk of the helium and hydrogen that makes it to
a new galaxy forms new stars, while other more dense elements combine to create objects
like asteroids, comets, planets and life forms.
Powerful supernova explosions can fling trillions of tonnes of atoms into space with such ferocity
that they escape their home galaxy�s gravitational pull and fall towards larger neighbours in
enormous clouds that travel at hundreds of kilometres per second. [Source]
The following computer simulation demonstrates our new understanding of the formation process
of galaxies:
These ejected elements are believed to be able to travel nearly a million light years
away from their origin before finally settling in new galaxies, as noted by a report in the
Monthly Notices of the Royal Astronomical Society.
�The surprising thing is that galactic winds contribute significantly more material than
we thought �In terms of research in galaxy evolution, we�re very excited about these
results. It�s a new mode of galaxy growth we�ve not considered before.� ~Daniel
Angl�s-Alc�zar,, an astronomer at Northwestern University in Evanston, Illinois
Using dramatic 3D models of how galaxies are born and then die, showing how a significant
portion of the material which comprises new galaxies is gathered from left over material
that has arrived from other galaxies. In our previous understanding of how the Milky Way
was formed, scientists had believed that most of the matter here was contributed by the
Big Bang.
The Big Bang theory has been popular among astronomers and physicists since the revelations
of Albert Einstein, but in recent years has been under intense scrutiny with some claiming
that it may be completely wrong. With this new simulation, the Big Bang theory moves
closer to extinction.
�Our origins are much less local than we thought, This study gives us a sense of how
things around us are connected to distant objects in the sky.� ~Claude-Andr� Faucher-Gigu�re
Another recent experiment offers the theory that the universe itself may actually be a
conscious organism, and that all matter within it is permeated with a consciousness of its
own. Combined with the recent discoveries about the origins of star-dust, we may be
on the brink of a major breakthrough in understanding our place in the cosmos.
