Hi all, another question....
The extension of the BH's horizon, if measured from external side....
has a measure different from zero and finite.... isn't it?
But what result could present a measure made from the "inside" (the

For those interested, there's an interesting paper by JH Field :-
Spatially-separated synchronised clocks in the same inertial frame:
Time dilatation, but no relativity of simultaneity or length
contraction

Keep in mind too, that what they paid for, it gets
If you were paid,to do something for church of relativity, they will
extract from you exactly what they were paid for
When we understand that, then we'll look at universities, schools,

"The Brilliance of Our Teachers"
    A recent newspaper question and answer column raised an interesting
subject. The query noted that, for a science course at a local school, there
were two instructors. One of those instructors explained the concepts

Kat, who has been diagnosed with cancer, has 4 years to live. Sh
volunteers on a space mission to Alpha Centauri (4.37 lightyears away)
travels at 0.866c, and arrives there ~5.0 years later. According t

According to high level relativity, relativity predict bended space.
wormholes, black holes, time travel, parallel universe, entangled
matter and many other nice things
If all that were true, then there should be UFO from other planets

There has been a fair amount of discussion on sci.physics.foundations in
the thread "Might Foldy-Wouthuysen Transformations contain a Hidden
Fermion Mass Generation Mechanism?" regarding the fact that the velocity
operator "alpha" of the Dirac Hamiltonian appears to suggest that a

It seems that the only thing Androcles wants to know is
"Why did Einstein say
the speed of light from A to B is c-v,
the speed of light from B to A is c+v,

It seems to me that principle of constancy of light velovity should be
integrated to principle of relativity in special theory of relativity.
There is my proof.
To be simple, thinking two inertial coordinate frames S1(x1,t1) and

Over the years I've picked up enough math/stats to understand the
pieces of general relativity and thus the explanation behind the
various paradoxes (twins, car/barn, etc.) However, on the Myers-Briggs
I happen to be an intuitive and can learn best when looking at things

New rules
High ranked relativists, owning big cars, are forced to go into
laboratory
and touch measurement instruments, at least twice a year.

**GR and Magnetostatics**
GR accounts for the magnetostatic force
quite simply, the key being the relation,
Length=(G/c^2)*Mass.    , G is Newton's,
