A $30B+ industry, applying relativity to create a global

your goat, eh Potter (Willy Lowman).

It is interesting to see that Sam Wormley
states that General Relativity is a $30B+ industry.

I knew that billions of the taxpayers, hard-earned dollars
went into trying to rationalize General Relativity,
but I didn't realize that Congress was stupid enough to
waste that much money on a non-cost-effective model
promoted by self-serving charlatans and their dupes.

As I pointed out,
after Newton's model,
there were immediate and rapid advances
in mechanics, astronomy, etc.

After the Faraday/Maxwell model
there were immediate and rapid advances
in chemistry, electricity, etc.

After the Watson/Crick DNA model
there were immediate and rapid advances
in medicine, genetics, animal husbandry,
the history of the Earth and Mankind, etc.

Here we are, 100 years after General Relativity
and it continues to generate more hype and heat
than light and advances, and waste time, money and minds on such
pursuits as time travel, worm holes, space warps, gravity waves, etc.

A mind is a terrible thing to waste.

It is interesting to see that Tom Potter doesn't quite
get it. For starters, SPEAR created the tau lepton using
electrons and positrons. The tau lepton is far too heavy
to explain without invoking either superluminal electrons,
or relativity. Most accelerators pour more energy into
their particles than is required to accelerate them to
Newtonian lightspeed.

Laser gyroscopes are based on the Sagnac effect, an effect
that cannot even work in an absolute-time-compatible
framework.

GPS is routinely used, but the construction thereof
required the satellite clocks to be compensated for
relativistic effects; otherwise the error will be almost
11 km at certain points of the day.

Even the astrologers have to account for relativity, though
probably not by a lot; the discrepancy is approximately 43
arc-seconds per century. Over 10,000 years that translates
into almost 12 degrees.

Whether $30B can be directly attributable to SR, GR, or both,
or not, I for one cannot say. Laser gyroscopes, though, are
good evidence. :-)

People think that libraries are safe. They're wrong. They have ideas.
(Also occasionally ectoplasmic slime and cute librarians.)
