The H&K is a joke....like all of relativity..

So you have no actual objections to the H&K experiment, you just don't
like what would happen if the Earth suddenly stopped rotating?

Fortunately for you, the H&K experiment started with the Earth rotating
and ended with the Earth rotating.

And fortunately for all of mankind, the oceans, and every living thing
thereon, I don't think it stopped anytime during the experiment, either.

Approximate moment of Earth: 2/5 M r^2 = 9.724 * 10^37 kg-m^2
Rotational speed: 2*Pi/86400 = 7.2722 * 10^-5 rad/sec
Rotational Energy: 1/2 I omega^2 = 2.571 * 10^29 J
Ocean volume: 1.370 * 10^18 m^3 (source: Encarta)
Water specific heat: 4186 J kg^-1 K^-1
Estimated ocean temperature rise: 44.8 million degrees
Temperature of Sun: 5800 K

Henri, I keep telling you that the speed of the planes change if the earth
stops. They go from flying at different speeds to flying at the same
speed
and that's why the clocks will read the same. Can't you understand that?

Don't be daft....

Duh... okay.

Use satellites outside the earth's atmosphere.

Same experiment.....

How can you say same experiment when you want to use satellites? Stick to
the planes.

If the Earth's rotation speed changes, how do the clocks 'know' how much
to
vary their rates?

Because if the speed of the earth's rotation changes, the speeds of the
planes change in relation to the centre of earth. The speed of the earth's
rotation is a factor in the speed of the planes, when the planes are moving
in opposite directions along the equator. Please tell me that you can
understand that. A clock at the north pole will run faster in relation to
one at the equator, (ignore any gravitational effects).

The H&K is a joke....like all of relativity..

Too bad you weren't around when Einstein was here, you could have saved him

You just love to make **** up, don't you?

If there is no angular velocity, the situation will be symmetric and
the planes will read exactly the same. Or satellites, or whatever.

It is obvious not only from an intuitive standpoint, but obvious from
the time dilation equation for that setup.

I have no idea how you can **** up something so simple so often.

Since you don't understand relativity, I am unsure why you are so

I would like your answer the question at the end
of this posting.

Two supersonic planes are flying in opposite directions
around the Earth along equator. The ground speed is
one Earth circumference per sidereal day (ca. 1670 km/h, MACH 1.36).
Each plane is carrying a ring laser gyro detecting
the rotation around an axis parallel to the Earth axis
(the pitch axis).
The planes are starting at a point at the Earth, and
returning to the same point one sidereal day later.

Case 1:
The experiment is performed on the rotating Earth.
How many rotations are measured by the gyros in
the East- and West going plane respectively?
(The obvious answer is: 2 and 0)

Case 2:
The experiment is performed on a non-rotating Earth.
How many rotations are measured by the gyros in
the East- and West going plane respectively?
(The obvious answer is: 1 and 1)

Now the question I would like you to answer:
Do you claim that the rotation of the Earth
somehow will affect remote ring laser gyros?
THIS HAS NOUGHT TO DO WITH THE QUESTION.

We are talking about clock rates.

You people claim the two clocks will run at different rates and will read
differently when reunited.

I'm telling you that if the Earth stops rotating as soon as the clocks are in
the air, their relative rates cannot possibly be affected and they should still
read differently when reunited (according to your silly theory).

But, since their whole trip is carried out when the Earth is NOT rotating, they
obviously should NOT read differently when reunited.

Even YOU should know that observer behavior cannot affect an observed object.
So considering that observer behaviour cannot affect
an observed object, do you claim that the rotation of
the Earth somehow will affect remote ring laser gyros?
No answer, Henri?

We're talking about clocks, not ring gyros.
Doesn't matter. Same problem.
They are both instruments inside the planes.

So we could make the question more general:
Do you claim that the rotation of the Earth somehow will
affect instruments inside the plane?

How is it that the H&K clocks would miraculously know how to change rates if
the (remote) Earth suddenly stopped rotating?
How is it that the gyros in my thought experiment would miraculously
know how to change the rotation if the (remote) Earth suddenly
stopped rotating?

The answer should be obvious, Henri.
And the answer is the same whether we are talking

I will give you a hint:
What is it the gyros measure?
Why are the results different in case 1 and 2?
What is the relevance of the Earth?

Paul, as usual you run away from the real topic and stall for time by talking
about something entirely irrelevant.

IF THE EARTH STOPS ROTATING AS SOON AS THE PLANES ARE IN THE AIR, HOW DO THE
CLOCKS 'KNOW' HOW TO ADJUST THEIR RATES SO THEY WILL NOW READ THE SAME WHEN

THIS SHOWS HOW NOINSENSICAL THE H&K REALLY IS.

WOULDN'T YOU AGREE?

The same experiment can be carried out using satellites orbiting in the
equatorial plane. Try thinking about it.

GR says the clock going in one direction will appear to run at a different rate
from the one going in the opposite direction. ..because the Earth is rotating
and each one's speed wrt the ground observer is different.
Therefore, when the clocks are reunited, their readings will be different.

This means that immediately after launch, the clocks must be running at
different rates relative to each other.

If the Earth stops rotating after launch, why should that difference suddenly
disappear...which is what GR says SHOULD happen?

It makes no difference whether the Earth stops spinning or not.

Of course. That is indeed the obvious answer.
The gyros and the clocks give different results in
the two scenarios, because the _planes_ move in two very
different ways in the two scenarios.
As you so correctly point out, it does not matter if the Earth
is spinning or not.

So the answers to your question:
" IF THE EARTH STOPS ROTATING AS SOON AS THE PLANES ARE IN THE AIR, HOW DO THE
CLOCKS 'KNOW' HOW TO ADJUST THEIR RATES SO THEY WILL NOW READ THE SAME WHEN
REUNITED?"
and my question:
"IF THE EARTH STOPS ROTATING AS SOON AS THE PLANES ARE IN THE AIR, HOW DO THE
GYROS 'KNOW' HOW TO ADJUST THEIR MEASUREMENTS SO THEY WILL NOW READ THE SAME WHEN
REUNITED?"
are exactly the same:

The clocks or the gyros don't have to know anything about
the rotation of the Earth because it does not affect them
in any way, it is the pathes of the planes through space and time
that determine what the instruments will show at the end of their journey.

In case 1, one plane is stationary in a non rotating frame,
while the other plane is moving twice around a circle at the speed 3340 km/h.
In case 2, both planes are moving in opposite directions once around a circle
at the same speed 1670 km/h.

"It makes no difference whether the Earth stops spinning or not."

Remember that for the future.

Case closed.

Paul
