We are just in the beginning. It understands nearly nothing to be
fair. And Its explanations of the rainbow are science's Leprechauns
with a Pot O Gold.

When science is old it will be much closer to the truth and won't be
in as much denial about what it thinks it knows.

I looked in the archives re variable stars and have seen posts back to
2005. And up to the stellar aberration strand on
sci.physics.relativity. Plenty for me to read there.

Some people seem to care, though maybe disbelieve. You were blasting
Jerry back in 2005 too. S/he didn't mind then, and lots of posters
seem to enjoy it which may be a particular trait in combative
physicists, but I find it sours me for reading the physics.

Your idea seems to involve speeds of v+c (I have only looked
briefly)? That would contradict SR. That's fine for you, but I have
not enough learning to disregard SR. I am not saying you are wrong,
just that I am in no position at the moment to agree or disagree. You
say it is easy, yet that cannot be so as so many people disagree.
They may all be wrong ... but it cannot be trivially easy.

I looked in the archives re variable stars and have seen posts back to
2005. And up to the stellar aberration strand on
sci.physics.relativity. Plenty for me to read there.

Some people seem to care, though maybe disbelieve. You were blasting
Jerry back in 2005 too. S/he didn't mind then, and lots of posters
seem to enjoy it which may be a particular trait in combative
physicists, but I find it sours me for reading the physics.

Your idea seems to involve speeds of v+c (I have only looked
briefly)? That would contradict SR. That's fine for you, but I have
not enough learning to disregard SR. I am not saying you are wrong,
just that I am in no position at the moment to agree or disagree. You
say it is easy, yet that cannot be so as so many people disagree.
They may all be wrong ... but it cannot be trivially easy.
==============================================
I've been blasting the bigotry of SR since 1993, but not until 1999
did I begin blasting in sci.physics.relativity.
Einstein's idea seems to involve speeds of c-v and c+v, each
of which he divides by c.

1) a = (c-v)/c
2) b = (c+v)/c

then he figures he can multiply a * b, take its square root, invert it
and call it beta.
3) beta = 1/sqrt(a*b)
= 1/sqrt( (c-v)/c *b)
= 1/sqrt( (c-v)/c * (c+v)/c)
= 1/sqrt( (c-v) * (c+v)/c^2)
= 1/sqrt( (c^2-v^2)/c^2)
= 1/sqrt( c^2/c^2 -v^2/c^2)
= 1/sqrt( 1 -v^2/c^2)

http://www.fourmilab.ch/etexts/einstein/specrel/www/figures/img37.gif

Since v+c would contradict SR (according to ben6993) then beta,
the cornerstone of SR, contradicts SR.

That's fine for me, but I have more than enough learning to disregard SR.
I AM saying you are wrong, its just that I am in a position at the moment
to disagree with you.
I say it is easy, yet that CAN be so as so many people are idiots and bigots
with their heads up their own arses.
They may all be wrong ... and they are. The only question is, do YOU have
the intelligence to read simple algebra?

What kind of lunacy prompted Einstein to say
the speed of light from A to B is c-v,
the speed of light from B to A is c+v,
the "time" each way is the same?

As I said a while back in a previous strand I intend to get around to
your question. I have read all subsequent posts about the issue. It
will take time as it can't be trivial. I agree that is is an
interesting question. Saying "according to ben6993" in your post may
mislead other readers without the rider that ben6993 is not a
physicist.

I would not be afraid to agree with you if I calculated that you were
correct. I have a far-fetched idea that gravity is a side effect of
inflation ... but I am not a physicist, so who cares what I think
about a physics matter. And of course I can't get the maths to work
on my model so I am not even convincing myself yet.

I once found an error in my friends completed PhD (not physics). Just
a minor error, though it needed a retraction as it reversed the sign
of the effect and therefore the conclusions pointed exactly the wrong
way. It reminds me a little of this issue. His error was getting
mixed up because of a double negative of the kind (a-b) -(c-d). In
your issue, somebody somewhere seems to be getting mixed up as to
which x length is measured in which frame. You may or may not be
correct ... however I will need time to look further. And even if I
eventually were to agree with you I am sure no one would be swayed or
impressed by it as I am not a physicist.

this site (as provided above by Cwatters)
http://answers.yahoo.com/question/index?qid=20090214124530AAfM4lg
gives a good answer but I think it's easier to see it from a view
point of energy.
By itself the neutron is unstable with a half-life of 10 minutes. It
decays into a proton, an electron, an anti-electron neutrino, and a
release of energy (not much, but some)
To drive this process backwards (recombine the electron and proton)
requires an input of energy. So they don't combine for the same reason
that water doesn't run uphill.
Now as to the deeper question, why is the neutron unstable, no one
knows.
Them's the rules, that all.
