Upon the NASA news of this:
http://science.nasa.gov/science-news/sc ... anplanets/.
Are the planets without the gravity center of a sun/star making up for the alleged Dark Matter? Is therefore Dark Matter a bad physics/astronomy joke?

Read about it yourself if you want to.

I don't know for how long the central stars of gravitational systems last (there is literature that you can check with), but as they explode in becoming dwarfs, the other planets, undeniably whir off to other orbits, taking on a whole new orbital life (insofar as they survive the explosion). So are these whirring planets of orphanage the secret behind "Dark Matter"?

I happen to have a Norwegian book on the subject, Astronomi - Fra strålende objekter til sorte hull - Vol. 2 (only) by Øystein Elgarøy and Øyvind Hauge with even a third title - Stjernehimmelen (perhaps name for the 2 volume series). Maybe I should buy another one in English and also bigger than this, 195 pages. It has, though, a strict university level content. There are no jokes in this book!!! It also has a chart for the typical life span of stars on page 85/92. This chart goes under "Main Series" of stars.

Happy reading, everyone! Cheers!

Wow, this is really interesting and I kind of half wondered if astronomers could really account for all the mass of the galaxy by observing, and it seems there really is alot of mass that has gone unobserved. I never really liked the idea of dark matter, always saw it as more of a placeholder for an unknown value, and I know this doesn't 'disprove' dark matter, but it certainly raises the question of if we do need to invoke such an exotic form of matter.

The situation.
1.
God has to be a real fool to think
that the >99% Hidden – Dark Universe
has no control of his <1% Visible Universe. And if he
knew this then he would not be a god but a physicist.
And if he was a smart physicist he would be laughing
at just how much less than 1% a universe really needs
to appear really real.

The Dark Matter is another official dogma of our astronomy.

Dark Energy may be Vacuum

And . . . .
Astronomers have found an enormous hole in the Universe,
nearly a billion light-years across, empty of both normal matter
such as stars, galaxies, and gas, and the mysterious, unseen "dark matter."
While earlier studies have shown holes, or voids, in the large-scale
structure of the Universe, this new discovery dwarfs them all.

We do not know what elementary particles are, we do not know how structure of physical space is, we do not understand the phenomenon of the time, we do not conceive the mater and the reason of Universe at all :( We miss fundamental model of the Universe...
