Einstein's Hypnotists Warn the Zombie World |
Although Einstein's zombies live happily with the consequences of the
principle of constancy of the speed of light (I measure your clock to
be slower than mine and you measure mine to be slower than yours, I
measure your stick to be shorter than mine and you measure mine to be
shorter than yours etc.) and have no intention to change anything,
Einstein hypnotists still find it suitable from time to time to warn
zombies about awful absurdities that would follow if the principle of
constancy of speed of light were abandoned :
http://www.centredaily.com/mld/centredaily/news/14178820.htm :
"Theoretically, strange things happen when you exceed the speed of
light," Schneider added. Time travel, for one thing, and a breakdown in
cause and effect. Schneider uses an example of hitting a target with a
gun that shoots bullets faster than the speed of light. "Some observers
would see the bullet hit the target before they saw the shooter fire
the gun," he said. "Since one of the guiding principles of relativity
is that all physical laws are the same to all observers, this violation
of causality would be a big problem."

Newton gets the last laugh and although you seem to believe that the
early 20th century notions are a valid extension or an improvement on
Newton's original ballistic agenda or a horrible perversion of that
17th century agenda,I am afraid none of you appear to be capable of
watching Isaac as he shuffles the astronomical deck and sets in motion
unintended consequences that are now only surfacing.
The question most should consider behind the overheated prouncements of
opponents and proponents is -
Is it worth it ?.
The answer is that cutting off your nose to spite your face,Newtonian
style,is no longer an option and has'nt been for a number of years and
even those whop are looked upon as experts in this forum are beginning
to find themselves now highlighted for all the wrong reasons.Proper
order !.

Meet me behind the bike sheds, and we'll compare, er, notes.

Causality is not violated. And this example does not
even apply : physical laws must be the same for local
experiments. And we realize that this locus of
application is getting smaller and smaller nowadays.
If the shooter uses a gun that hits the target faster
than light, he can also send an FTL message to the
observers that he fired his gun. Causality restored.
