Neutron star and no black hole

Saul Don't know what you are referring to with my being 200,000 years
old. The Crab Nebula is a famous remnant of a supernova explosion that
was observed and documented by Chinese astronomers in 1054(before my
time) Yes I have enlarged pictures of these explosions plus the Cygnus
Loop ,and that supernova occurred some 15,000 yeas ago. I'm big on the
great explosions with their implosions for I know they created heavy
elements needed to create life. Well Saul I'm old,but when I
was 8 I had more brains then you. Bert

Hi Bert,

It's 30 degrees here (first frost) but at least the stars are out,
which I haven't seen much of since September. They have moved quit a
bit to the west since then, new constellations coming into view.

It's kind of nice how looking into the sky is really looking into the
past. When the light left Sirius, my life was still on track and I had
much more hope for the future. When the light left some of the other
stars, I was still young and dating my dream girl. When the light left
that smudgy patch I keep catching out of the corner of my eye in Orion
(the Orion Nebula), the religion of Islam had not yet burst upon the
scene (the good old days!). And when the light left that bright red
planet Mars, I was still inside where it's warm!

Today is election day in many places, but here in Oregon we don't get
to vote. I think the politicians here abolished the democracy when
nobody was looking! So the only news is about the crooks being elected
elsewhere.

Hi Double-A Heat breaking records here in the south. Today in Micky
Mouse land it will be 85 F sunny. Last night our sky was very clear,and
we had a half Moon. Venus was very bright. Still Florida is no
place for looking at the sky with a telescope. I gave up the idea of
buying one. Seems we can easily look at the past.Reality is the future
is not all that big a mystery. Light,and time are so very symmetrical

From Bert:

Comparing a neutron star to a black hole is not bad thinking. One is a
grape(neutron star) the black hole is the
prune. Reality is if a neutron star lost its
spin it would be black

Hey Bert, surely you're familiar with the Hulse-Taylor pulsar, are you
not? It was one of the most important discoveries in astronomy, giving
evidence (albeit indirect evidence) of gravitational wave radiation,
predicted by Einstein in 1916.
If you're really averse to Google, try www.yahoo.com
and type in 'Hulse Taylor pulsar'.

Hi oc Can't go to Google,as far as I know I've never heard of the Hulse
Taylor pulsar??? I know of two guys that kept measuring two
neutron stars that were orbiting around each other ,and their
measurements help prove GR,and both got a Nobel. oc tell me about this
pulsar (please) Bert

Hell's bells, Bert. Just take a deep breath, hold your nose, and do a
Google on it ferchrissakes. oc
