is that why there are less LX90's now. Theories are good, they are hard to disprove until science gets cleaver enough to do that.

Sorry Houghy science puts up an hypothesis. and if the evidence fits it becomes a theory and if furthur evidence modifies the the theory.then science adjusts the theory accordingly.
One example.
Newtons laws of motion , worked OK, problem with Mercury's orbit?
General Theory of Relativity from Einstein solved that one
Etc

Theories are just that, a basic hypothesis that works so far.Open for rational discussion WITH evidence!

Of course we should have realised, the extinction would have started there...:lol2:
