Existence is relative. If you cant observe time, it "appears" to go
away. I think that it cant be observed on extreme scales, hence, the
Oreo Cookie Universe Theory. A sweet creamy filling of pure
unadulterated existence, sandwiched in between two crispy wafers of
nonexistence on extreme scales because time cant be observed there.

Metaphysical musings don't get us any closer to
the notion of time than a couple of kids can
measure with a fuel can on a Sunday afternoon.


Sue...



But neither the Ford nor the Chevy can make an observation in less
than
Planck time.

You have 3 things going on here.
1) Observability of time
2) Observability of length
3) Observability of motion, which is a composition of (1) and (2).

Ford observes Chevy, and Chevy observes Ford. But this requires t
PlanckTime, otherwise they cannot make an observation at all.


The reason I specified a Ford and Chevy is because
everyone knows they come with special brackets for
suspending a physics laboratory between a pair. :-)

I suppose it was too much to ask for you to realize how this
piece of nonsense came into existence, but the permittivity of vacuum
is an eansy weansy tiny bit different to the permittivity of aether.
tan(89.999999 degrees) isn't quite the same as tan(90 degrees) either.

Indeed. If the loosing driver isn't observing, then his
remaining fuel will go away through a siphon hose so the winner can
make it home. :-)

Sorry, painting white strips on the traction wheels has no
effect here.
The rusty lamp appears to be getting dimmer.

INVENTORY

You are carrying a rusty lamp (providing light), an elvish sword, a
guidebook, a jar, a pile of cheese and a pepperoni. It seems that the
jar is half-full of tomato sauce. You are wearing a magic shawl.

Your lamp is getting dimmer...

As you can see, normal people believe any rubbish. To be a crank,

Here is an example of how to fish.
The needle is the hook, the plate is the sinker, the line is the one
I spin. Then you spot a normal fish with a Ph.D. swimming and
cast your bait, which is swallowed hook, line and sinker.
Reel it in slowly if it's a big fish, or land it fast and throw it back
if it's a minnow.


You're a lousy troll, too, Androcles. A real troll wouldn't need to
persistently reply to my posts, or repeatedly request me to reply.

Androcles casts his line:
Ok, Now reduce the area to a point, say one atom at the end of a
needle.
Apply some large voltage (say 1,000,000V) between the needle and a
plate (any area).
Start with d large, say 1 kilometre. Gradually reduce d. What happens?

Nieminen:
Anyway, I'd say that about the same thing would happen if you brought
them together in empty space as if you brought them together in air,
until
the fields became large enough to get fun stuff like arcing, ion wind
etc.

Androcles cranks his reel:
You would, huh?
That ends the discussion, then, my TV needs a vacuum to operate.


You have a megavolt TV?

Anyway, I'm sure your family is glad that you post anonymously. If people
knew you were related to them, they might think it might be genetic ...

**** off, Nieminen.
A **** like you isn't a physicist, you don't even know how a TV works.
I baited the hook, reeled you in and threw you back.
I can outsmart you anyday. Game over, minnow.
Now **** off.

OMG that is funny.

I saw a documentary about Richard Feynman, and also remember his
investigations into Challenger disaster. I think that he's pretty much
the consummate 20th centiry scientist.

And I think that if he were here, posting on this thread, he'd
probably give a pretty good argument against what I'm saying simply
because it seems ridiculous to treat nonexistence as a physical
phenomena. I think that even Einstein felt that way if I'm not
mistaken.

Feynman's math seems to make a tenuous dance around the idea of
nonexistence, always careful not to step on it.


If the universe doesn't exist, then we don't need to study it.


Neither do we need to study it if it exists. But in either case, it
is fun doing so.


It would be much easier to study if it did exist that if it didn't,
since if it didn't we wouldn't!

, you don't even know how a TV works.


You think you have a megavolt TV?

You think there is room-pressure air inside a CRT?

Why do you think a vacuum tube is called a VACUUM tube?

And while we're at it, here's another simple question you keep cutting and
running from:

When is 5 hours earlier than 5 hours later than now?

**************

Nope.

Determinism is possible for simple systems, like billiard ball motion.

Complex systems develop free will, such as humans. A good example is
the fact that I straightened you out on this, and you came back
swinging, but I, like the American Military, shoot from a safe haven
and don't risk myself.
