How did you come up with 5%, John?
1 part in 20 is a pretty big fraction.

Odd- from Wiki:
"Neutrinos do not interact significantly with matter and therefore do not help support the Sun against gravitational collapse. Their energy is lost: the neutrinos in the ppI, ppII and ppIII chains carry away 2.0%, 4.0%, and 28.3% of the energy in those reactions, respectively.[7]"
Since the first one is the main reaction,
it will be less than the 5% I guessed

I'm not following. The wiki article is saying that those fractions are 
the amount of energy carried away by neutrino in those particular 
processes in our particular sun.

The statement you made is that neutrino energy absorbed by black holes 
accounts for 5% of the total energy of the universe.

Those two don't seem to have much to do with each other, other than they 
are both statements about neutrinos.

It's like if you made a statement that illegal drugs traffic involves 
90% of the black people world-wide, and to support that you cited a stat 
that 90% of the drug arrests in Camden, NJ, were attributable to black 
people.

Follow this- right now there seems to
be a gazillion-plus neutrinos going
everywhere and doing nothing.
And they're looking for "Dark Energy".
Following so far?

Neutrinos were considered as a candidate for dark matter (not dark energy
as they hardly interact at all), but apparently all the models predict 
that there is nowhere near enough of them to explain dark matter.  I am 
not familiar with this type of prediction so I don't know any more.

   The neutrinos that we know about are "too hot" to clump on the
   observed scales, and therefore are not good candidates for dark
   matter.

No, not really, but it does make we want to ask you to explain your

This seems to be veering off track. I asked you where your 5% number for 
total energy loss from neutrino absorption by black holes came from. So 
far you've quoted an unrelated number about energy losses from the sun 
attributable to neutrinos.

But on the question of dark matter or dark energy, neutrinos have been 
considered (and I believe ruled out) as a candidate for dark matter. You 
can google "are neutrinos dark matter candidates?" to get a good list of 
articles about that. Neutrinos going everywhere and doing nothing would 
not have the behavior required of dark energy.

Yeah, what about them?

>So- now- tiny amount? What?

Read what I wrote.  For neutrinos from one galaxy to interact with
another, pushing them apart (or so you claim), they'd have to enter and be
absorbed by its central black hole, otherwise they'll go right through the
galaxy. So I repeat, what's the cross sectional area of, for example, the
black hole inside Andromeda, as seen from Earth, and what percentage of
the Sun's neutrinos will encounter it?  I'll help you: Andromeda's black
hole has a radius of about 4.68×10^11 meters.

>If BHs are the only thing that stops
>them, ALL the energy from ALL the

Say, what?  For a neutrino to be absorbed by a black hole, it will have
to actually encounter one first.

Maybe you can come up with a rough estimate of what portion of the sky is
in direct line with a galactic central black hole (or any other black 
hole).

>That's like 5% of ALL energy.

Yup, a lot of energy (dunno about 5%) is locked up in neutrinos, mostly
forever gone.

>What do YOU think happens to the
>energy from neutrinos,
>Michael?

They mostly go on and on forever.

Well, I'd agree with you 100% except for the simple fact that you are 
wrong yet again. 100% wrong.

But what if they're going everywhere and
pushing on (being absorbed by) BHs?

Quantitatively, the amount of momentum carried by neutrinos, not even a 
bazillion of them, is enough to account for the acceleration of the 
universe. This is where calculations come into play, not just general 
directional hand-waving.

Nah, I don't think that makes sense, John.

Because all that ends up happening is that you point in more or less 
random directions, having no idea whether the direction is likely to 
have any payoff, and then you want other people to explain why it's a 
no-payoff or a payoff direction.

That, frankly, is the lazy man's approach.

Numerical literacy and the ability to find key numbers online and then 
do basic back-of-the-envelope calculations to see if it's remotely 
sensible, is a basic scientific skill. Anyone who is interested in 
scientific idea needs practice in this skill.

This was taught to me in science classes from high school to college. We 
worked simple things like: how long does it take for a low earth 
satellite to orbit the earth? This you should be able to calculate only 
knowing the diameter of the earth and the value of g, and you should be 
able to calculate it in your head and get an answer that is good to 
about 1 part in 20.

Did you ever figure what percentage of neutrinos from the sun (or the 
Milky Way as a whole) would be absorbed by the black hole at the center
of the Andromeda Galaxy?  How many zeroes do I need between the decimal
point and the first significant figure?

Now multiply by the number of neutrinos per second the sun releases.

Also, did you figure out what percent of the sky is directly in line with
a galactic center black hole?  Assume each galaxy has one, and a Milky Way
sized galaxy has a Milky Way sized black hole and the others are 
proportional.

Once you've done that, I'll have more homework for you.

Zero. And Zero. Go measure.

Zero times what?

Did you MM figure it out?

Thanks Teacher, may I/We have another?

Michael-
Olber, Ulber, whatever, already did it.
From far enough away the entire sky
should be blazing. But it's not. Why
not? Photon absorption by dust.
But neutrinos don't get absorbed by 
dust. So- if we could "see" neutrinos,
the whole sky should be blazing.
So if BHs absorb neutrinos, which I say 
they do, they should absorb them all.
100%. None get away. No "heat death".
A cycle, Michael.

That's not the reason.
Google "Olber's Paradox"

Nope, for same reason it's not true for light, which has nothing to do 
with dust absorptoin.

EVENTUALLY all would hit a black hole IF the universe is unbounded. But 
that might take quite a bit longer than the age of the universe. MOST 
neutrinos that have been emitted sometime in the last 13.8 billion years 
have not traveled far enough to hit a black hole.

But let's suppose the universe is bounded. In this case, if you keep 
going straight in some direction, you'll eventually end up right where 
you started. Or at least you'll end up in some place very near to where 
you started. It's like traveling straight ahead on the surface of the 
earth, veering neither left nor right, and you're not sensitive to the 
curvature of the surface. Now ask, "If I head in some random direction, 
will I eventually run into a volcano." Well, maybe. It might not happen 
on the first pass around the earth. Maybe it happens on the 3978th pass 
around the world, each time your path being a little different than what 
it was before. But it's also possible that you NEVER run into a volcano. 
Because there are only a finite number of volcanos on the earth, and 
it's possible to pass an INFINITE number of times over the surface of 
the earth and there still be some places you never get close to.

Michael-
You realize, don't you, that if the
Universe IS bounded, and the
neutrinos keep coming around,
there will be a higher and higher
density of them?
That actually shoots the argument you
appear to be making right in the foot
:)
