What if(on Holding Their Shape)

shape in the vacuum of space? M57 is a very pretty ring nebula. It
looks like a smoke ring. Smoke rings do not keep their shape for long.
Actually M57 is not a ring but cylinder shaped(we see it as a ring
because we see this cylinder head on. This is a planetary nebula,and
like all planetary nebular it was caused by a star exploding,and M57
does have a white dwarf in the center of its ring. Again my
question is How does it hold this cylinder shape for millions of years.
Seems common sense tells me it should defuse. It is big at 1.3 light
years across. The white dwarf gravity is not the answer Bert

M57 is an example of a planetary nebula, Herb. The expanding outer
atmosphere of gas was "puffed off" the convulsing red giant star before
it shrunk down to an earth-sized white dwarf. The central white dwarf
star is so hot that UV "illuminates" the expanding bubble of gas. Here
are other examples of planetary nebulae.

show it. Staying so very ring shaped. Staying so beautiful in form is
what my post is all about. Don't you get it? Why staying in form for
millions of years.? When will it lose this ring shape? When will you sam
answer this simple question? Sam do not go to Google all the time. Be
your own thinker. It takes time and lots of thinking,butyou must try

How do YOU know that's what it looked like a million years ago, Herb.
The fact is you don't!
When will it lose this ring shape? When will you sam

I take it you are unwilling or incapable of finding out anything
on your own. Is that right Herb.

planetary nebula. looks like a circle. So you concluded that it is a
cylinder, The way spherical soap bubbles, illuminated from behind,
look like brightly lit circles.

together. Or rather, distance is holding it together. The distances
involved are so huge, and the velocotiy of the gas so small, that it
takes millions of years to disperse.

spherical buble. And it is dispersing. Planetary nebula are relatively
rare. Each ring takes thousands of years to disperse, not millions.
On the distance scales involved, thousands of years is almost no time
at all.

You missed a few o's.
You mean he wasn't really asking a question? You mean his
"question" was just a vehicle for insults?

Get the picture?? I hope so. Learn to think Sam. It will make your

Astronomers use spectra and Doppler to measure velocity of the components.
You should take an introductory astronomy course, Herb. Ignorance is
correctable.

explained the "doppler"effect It determines "distance and speed" If you
could think Sam you would know how this does not really fit with my post
main question on shape staying put. You can't think so I have to forgive
your fudging Sad but reality Bert

two 1,000 years the rings are gone.(can not argue with my lovely Darla)
White dwarf in the middle of ring will last a trillion years gas ring
around it few 1,000 years Hope its written in stone and not be a
fudgical answer ??? Bert

3C 273 reason it has a black hole in its center that has the mass of a
billion stars. At this present time it is just one of the universe's
greatest black holes. I am sure it reached its critical mass density and
thus exploded many billion years ago. Black hole critical mass density
is one of my Nobel theories. It goes back to 1966 That theory came to
