Lonely planets found which float freely through the Milky Way

More seriously: <a href="http://www.jpl.nasa.gov/news/news.cfm?release=2011-147" rel="nofollow">http://www.jpl.nasa.gov/news/news.cfm?release=2011-147</a><p><i>The discovery indicates there are many more free-floating Jupiter-mass planets that can't be seen. The team estimates there are about twice as many of them as stars. In addition, these worlds are thought to be at least as common as planets that orbit stars. This would add up to hundreds of billions of lone planets in our Milky Way galaxy alone.</i><p>wtf

Now, witness the power of this fully armed and operational battle station.

This is a bit confusing, since a planet is defined as "a celestial body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighboring region of planetesimals.", the relevant part being "Orbiting a star or stellar remnant". I wouldn't think it would be possible to have a freely floating planet.

I think is less surprising than the fact that Jupiter, and in fact all 4 big planets in our solar system, are actually just gas bubbles, and not actually not the rocky balls us ordinary people imagine as planets. That's right: they have no surface.<p>These planets are just too small to be stars.

This was a preview of the astronomical models of the Theory of Matrix / DNA, 20 years ago. Lonely planets float freely in space until they have close to a star and be caught in its orbit. The energy of the star reaches the core of the planet which is a germ of star and triggering the start of a nuclear reaction. When the planet's consumes its mass and becomes light it escapes from the stellar orbit, returning to float in space, it grows becoming a pulsar and then unfolds as a supernova. In <a href="http://theuniversalmatrix.com" rel="nofollow">http://theuniversalmatrix.com</a> website everything is explained.

I wonder if they are moving fairly fast because with that much mass, if they have not been sucked into a star/black hole yet, then their slingshot would have massive momentum.

Also known as "Rogue planets". (Source: Star Trek Enterprise ep. "Rogue Planet").<p>Sure enough it's fiction, but I can't think of a better nickname.

Small dyson spheres?
