I suggest that the deadbeat scientists on the public dole
who use billions of the taxpayers dollars

to fork Relativity onto friendly data,
should keep the information to themselves
and use it to make a few bucks in the free market.

Face the facts folks,
rather than start with the enormous amount of extant data
and use it to create models that are useful to society,

deadbeat scientists on the public dole
start with General Relativity,
and use Newtonian and Maxwellian physics
to fork Relativity onto friendly data,

in an effort to use the taxpayer's money to by billion dollar toys,
to promote the fiction that they are privy to powerful, esoteric knowledge,
to attend conferences at interesting places in the world,
and enjoy high pay, great benefits and great retirement income
and immunity from the necessity to generate
any useful products and services.

You won't see deadbeat scientists on the public dole
hyping the fact that the speed of electro-magnetic radiation
is a function of the permittivity and permeability of the medium
as was understood by Maxwell, and as understood and USED
by today's designers of antennas, strip lines, transmissions lines,
wave guides, traveling wave tubes, backward wave oscillators, etc.
