It is now assumed that space and time began maybe 15 or 20 billion years
ago. Poe may be wrong.


Albert Einstein speculated that the speed of light is a universal
constant. He may be wrong.

There has never been a contradictory observation that the speed of light
is other than a constant, ever.

A.A. Michelson and E.W.Morley in 1881 measured the speed of light in the
direction of the Earth and the speed of light at right angles to the
Earth`s motion. No difference was found.

Light does have different speeds in different media. This causes light
to bend when passing from one medium to another. The "speed of light" is
through space or a vacuum. The more a substance bends light, the higher
its refractive index.

I said Einstein may be wrong. I should have added that I don`t think so.

Heh, heh, and nobody has ever gotten *exactly* the same results. :-)

Or to put it in more realistic terms, as instrumentation gets better
and better, the value of c gets more decimal points.

By 1947 it was to +/- 3 km/s, in 1958 +/- 0.1, and by 1973 +/- 0.001.

To put things in perspective, +/- 0.001 km/s is an error of .000000000007%.

I predict that Einstein was wrong by the same percentage that Newton
was wrong. After all, physics is a converging series. :-) In 100 years,
I predict that Einstein's theories will be just as obsolete as Newton's
theories are now. 'Course, my great-great-grandson will have to collect
any bets.

Perhaps you might read:

http://scienceworld.wolfram.com/biography/Einstein.html

and tell us where there's a place for a "percentage" where Einstein might
have been wrong.

Current Truth is: "He not only plays dice, he sometimes throws them where
even He can't see them."

Actually, what he said was "God does not play dice with the world.".

He also said "Nature shows us only the tail of the lion. But I do not
doubt that the lion belongs to it even though he cannot at once reveal
himself because of his enormous size".

As to playing dice with the world, we just got near-missed by a decent hunk
of rock last week. It's coming back in four years; do ya feel lucky?

How fortunate Al didn't try to make a living as a taxonomist.
