Whether Not Many Worlds Will Survive or Not?

Newtonian mechanics is not fundamentally true. It's been superseded by quanta mechanics and relativity. But there is still a limit in which it's a very, very good description of what happens. You don't need to know general relativity to fly a rocket to the moon. Newtonian mechanic and gravity works perfectly well. I expect that will be the case going forward. Whether not many worlds is going to survive or not. i mean, i have, i have a credence. So i think all the work here isi being done by the word justified in that last sentence.
