*** I was thinking ... :Physics:Thoughts:
|
|
|
|
about dark matter a bit earlier today. We know that the ordinary matter counts for
|
|
|
|
~5% of the mass of the universe and the rest is kinda on dark matter's shoulders. It doesn't
|
|
|
|
interact with light and in our knowledge almost with anything else as well yet it's there and
|
|
|
|
it's massive. We know that neutrinos which are very weakly interacting, electrically neutral particles
|
|
|
|
are part of the entity or thing that we call the "dark matter". But since it has very little mass
|
|
|
|
it would only take a relatively small amount of mass to account for all the dark matter out there.
|
|
|
|
|
|
|
|
Anyway, I was thinking that we exist because of the asymmetry of matter and anit-matter and the
|
|
|
|
matter that creates us and the entire 4.5 billion years history of the earth is just about 5% of the
|
|
|
|
universe. Galaxies that look like a disk to us in fact are more like spheres that the rest of the sphere
|
|
|
|
is fill with the dark matter. What if the rest of a galaxy that we can't see is no just random dark
|
|
|
|
matter, I mean what if there are more to a galaxy rather that the starts that we see? what if there are
|
|
|
|
planetary systems made out of the dark matter ? What if these planetary systems grew their own life form
|
|
|
|
via evolution? A life form that doesn't interact with ordinary matter (ordinary to us) and light ?
|
|
|
|
How they might be ? How we might ever learn about them ?
