String and Multiverse Theory are basically forms of Theology. The difference from traditional religion is that the high priests of these Theologies have PhD’s in physics, etc. That doesn’t make their theories any more valid than Catholicism or Hinduism. They are pure belief systems without evidence. Multiverse Theory is especially attractive because it is impossible to prove. Grant money can flow unhindered forever because of it. People are simply expected to believe it because the “experts” say it is so.
yep - for a short answer
money - for a concrete answer
prove it - for a non answer
Agreed. If a theory is not experimentally falsifiable then it is not a true scientific theory. It is merely a belief system.
String Theory has so many unknown parameters that you can basically build any universe you want by just fiddling with the knobs in the equations. It doesn't have any real predictive value.
