Stardust and Dark Matter
Sometimes discoveries made in the heavens have direct implications for us on earth. For if you think about it for just a moment, we are ultimately all composed of stardust. We came from the stars, and one day we shall return to them. Whatever the makeup of stars may be we are made of the same molecular stuff.
For almost a century, astronomers, cosmologists and physicists have been examining the idea that the Universe that we can see may only be part of what is out there, and that it may contain material that emits little or no detectable radiation. The most recent estimates are that more than 90 percent of the universe is “missing.” We know that it is there because of its effects, but we cannot see it. This missing piece of the Universe is being referred to as “dark” matter. There is another idea that there is something called “dark” energy, that is causing the Universe to accelerate. We know very little about dark matter, but it is utterly extraordinary that our vision of the universe may have been so incomplete. Some visionary scientists have been wondering if this dark matter and dark energy may have something to do with the burgeoning evidence for the existence of “subtle” systems associated with the body, which have been given names like Qi (Chi), Prana, the Etheric or the Fifth Element, after Earth, Fire, Air and Water. An interesting an entirely speculative idea that we shall return to in a future post.
Some scientists have remained skeptical about the very existence of dark matter, so it is fascinating to read the announcement from a team at John Hopkins University who has been using the Hubble telescope to map the location of invisible dark matter in unprecedented detail in two very young galaxy clusters. The new findings, reported in the Astrophysical Journal, lend support to the theory that the galaxies that we can see in space form at the densest regions of massive “cosmic webs” of invisible dark matter. This is rather like the way that froth gathers on top of ocean waves.
Though so little is known about dark matter, these new findings are consistent with one of its most spooky properties. Normal matter can collide and scatter like so many billiard balls, but dark matter appears to be “collision-less.” When particles of dark matter meet each other, they seem just to pass through each other. Yet they can clearly interact with “normal matter.” You will see why some scientists have engaged in some extraordinary speculations about the role of dark matter on the earth and in our bodies.
This is an area of research that we shall continue to monitor closely.
