You know, Tipler is tenured, so Tulane can't fire him for spouting off his crazy shit. I can assure you that if he was a new PhD looking to get hired to a tenure track position and he was flogging the crap he is today, he would never be hired.
That's why Tipler should really STFU about how the peer-review system and science is so terribly flawed, since the tenure system is set up to keep institutions of higher education from being able to fire professors for having "out there" ideas.
The same happened with UFO abduction believer John Mack at Harvard.
