Is there any definition that gives the additive identity for time?
This one doesn't cut it:

we establish by definition that the "time" required by a turtle to
travel
from A to B equals the "time" it requires to travel from B to A.

Ref: http://www.fourmilab.ch/etexts/einstein/specrel/www/

Einstein can prove nothing can go faster than a turtle.

Oops!... Did I say 'a turtle'? Sorry...'light'.

Well... moortel's favourite pastime is supporting the phuckwits
who support relativity, and moortel is the topic.

Based
