"It is often stated that of all the theories proposed in
this century, the silliest is quantum theory. In fact, some say that
the only thing that quantum theory has going for it is that it is
"There are many examples of old, incorrect theories that
stubbornly persisted, sustained only by the prestige of foolish but
well-connected scientists. Many of these theories have been killed
off only when some decisive experiment exposed their incorrectness."
"Thus the yeoman work in any science, and especially physics,
is done by the experimentalist, who must keep the theoreticians honest."
"It would take a civilization far more advanced than ours,
unbelievably advanced, to begin to manipulate negative energy to create
gateways to the past. But if you could obtain large quantities of
negative energy -- and that's a big "if" -- then you could
create a time machine that apparently obeys Einstein's equation and
perhaps the laws of quantum theory."
