Brown Dwarfs

These are bodies that are not massive enough to become a star.That
means
gravity can not create pressures,and temperatures at their cores to
cause nuclear action(fusion) Now this creates lots of questions like
Is Jupiter a brown dwarf? Are there more brown dwarfs in our galaxy
than
medium mass stars(like our sun?) More brown than white dwarfs?.
How
does one detect a brown dwarf? Do most stars have a brown dwarf in
orbit.? Lets think of their creation out of contracting gas cloud. The
cloud must create the pressure that gives the internal heat(yes) Can we
blame the cloud for not creating a star?(low density. Can we blame a
supernova going off to far away to seed this cloud with heavy
particles(dust),and thus it does not have enough of the right stuff
needed to create a sun. As the universe gets older are these clouds
thinning out so that only brown dwarfs are possible. My thinking has
always been supernovas were very plentiful about 8 billion years
ago(earlier spacetime) Well I was going to put
this in todays "What if" but Double-A,and Twitty have trouble with that
post. How is this working out for you guys? PS I could also think
in
the other direction,and say brown dwarfs are created in a spacetime
when
there was no such elements as nitrogen,carbon,silicon,or iron to add to
these large hydrogen clouds. When I think in both directions at the
same
time my head spins like a dog trying to catch his own tail. To slow the
spin I put a can of beer in each hand,and hold my arms out as far as
possible. See its working Wish the game would start already

What did you do, Bert. This post hasn't shown up in the Google
newsreader at all! I had to copy it over from Outlook and post it as a
new subject. Maybe they heard you bad mouthing them!

Yes, holding those beer cans out at arms length should slow down the
spin. As long as you don't let them come close to your lips again,
your head will eventually stop spinning.
