"Common sense" tells you that you cannot walk on the ceiling, yet
flies do so all the time. That is just a factor of ~400 in scale,
FAR smaller than the ratio appropriate for relativistic objects.


Anyone buying into TD needs their head read!


You simply do not have a clue. Your GUESSES and OPINIONS are worthless, because
you do not understand the subject and have never studied it.

Grow up. Stop trying to be what you aren't. If you are really interested in
physics (which seems doubtful from your posts around here), you need to STUDY --
nobody ever learned anything with their mouth open, or by posting nonsense to
the net.

For those who are interested in physics, I'll point out that
"time dilation" has been observed many times in many ways,
and agrees very accurately with the predictions of SR. Real
experiments trump the naive guesses of Byron Forbes (and others).


Tom Roberts



Ok stupid, let me walk you through it.

In any clock experiment we can move 2 clocks apart and later bring them back together at rest.

We have 3 phases of acceleration -

a1 - moving one away
a2 - move it back toward the stationary one
a3 - slow it down to rest

In between a1-a2 and a2-a3 we have 2 periods of constant v.

We can have this constant v for any duration we like. A large duration renders the effects of the 3 acceleration
phases as negligible. So this should always yield both clocks as being slower - which is ridiculous.

Then Einstein attempts a fudge with grav' TD. It's true - he's a lier!

Only an idiot cannot see that.

Behold how ****ing stupid this planet is!

Behold the pitiful ways the gods amuse themselves - silly ****s!

What's to believe? This is the way nature behaves--confirmed

There has *never been* an observation that contradicts a
prediction of relativity theory. Relativity remains a fruitful

Still a lie, an overt one at that...


Cite evidence!


Alias Effect


Ah, the 'effect' that manages to evade observation a rather large
percentage of the time?

the *need* FOR Dark Matter


Explain observation without it. Have fun.

DI Herculis


Does not meaningfully contradict GR. Feel free to elaborate by explaining
exactly what GR's prediction for the Heruclis system is supposed to be.


To name just a few 'observations' that did contradict the
PRE-diction of GRT...

Bzzzt!


Galactic rotation curves do not match Newtonian predictions
either. This is NOT a problem with GR.


Except that GR becomes Newton's theory in the weak slow speed
limit. *Pay attention, the issue is NOT! the validity or not
of GR its the silly claim that no observation has EVER!
contradicted the PREdiction OF GR! *That is, on its face,
a falsehood and to persist in insisting so is overt lying!


Our inability to definitely isolate and identify the root cause
of the discrepancy between observed galactic rotation rates and
the observed distribution of luminous matter simply means that we
don't know for sure what is going on. It does not necessarily
point to a failure of existing gravitational theory. Rather, it
indicates a need for further study. Replacing GR with modified
gravitational theories have observational consequences that have
yet to be verified.


MOND (and family) completely fail the higher multipole peaks of the
CMBR, and literally require dark matter to explain cluster mergers. It
isn't often when I crack up while reading a paper about MOND, but that
did it.

MOND is an interesting heurestic that gets way more stuff right than it
ought to. Put it on the shelf next to the Balmer formula for the
Hydrogen energy levels.


MOND is strictly an empirical fit. The furthest developed
alternative theories of gravity seeking to explain galactic
rotation curves, such as TeVeS (Bekenstein), NGT (Moffat) and
Conformal Gravity (Mannheim), are all ultimately based on GR.

Jerry


That roughly sums it up, but there's a wrinkle which makes the
invocation of the theories even stupider than the already-low baseline.

All these alternative theories like TeVeS rely on some value of extra
scalar/vector/tensor fields on top of the regular GR Lagrangian, adding
oh so many raw degree of freedom which makes, in my opinion, any
prediction from those theories about dark matter into a joke.

People who reject dark matter but flee to those theories are some
combination of stupid, clueless, or tone deaf.

No. Only one clock is in an inertial frame of reference. The situations are
not symmetrical.

Gravity has nothing to do with the Twin Paradox. The clocks show different
times because one twin stayed in a single inertial frame, whereas the other
twin didn't.


Only an idiot cannot see that.

Complete bull****.

Again, you already agreed the acc phases are negligible.

All that remains is the relative v. And that's all that 'stein refers to.

So then that clock is sped up from the other's point of view which contradicts TD.

Assuming "TD" means time dilation, that *is* time dilation.

I do.

The difference appears to be that I have studied physics and you have not.

Which is why you are unfamiliar with basic concepts in physics and
mathematics.

Like I said, you should study physics if you are interested in it.

Idiot Webb would only live for 2 hours if he were at rest like his
brain, resting in peace. But because he moves he lives much longer
thanks to time dilation. It is observed every day in cemeteries, people
that are at rest are as dead and decayed as muons in particle
accelerators that are at rest. Muons that move live normal lives in
particle accelerators.
You are ****ing insane, Webb, NOBODY has ever observed time
dilation.
