I think it's ok for 'we don't know and can't prove this one way or the other yet' to be a valid scientific stance. It's a good way to avoid rampant scepticism which in my opinion is incredibly unscientific in itself. Also as a side note I was interested while watching this video to realise that the multiple universe theory is entirely separate from the idea of additional spatial dimensions. It's so great to live in a world (perhaps one of many worlds even) so full of possibilities.

FWIW, It doesn't have anything to do with the Mandela effect; there is no way to end up in the "wrong" universe, there is no way one could possibly know which universe one's in, and the number of total universes is beyond anything we could possibly comprehend. To be clear: A given universe "splits" every time there is a quantum event (any interaction between subatomic particles, including a measurement). en.m.wikipedia.org/wiki/Event_(particle_physics) I don't think Simon gave it a fair shake. Does it really make any more sense to propose that a given subatomic particle doesn't have an actual location until it's measured?

Technically we “could” find evidence if, and only if, another universe impacted our own. The result would likely (speculation at best) leave a so-called “cold spot” where no matter is found cause it was pushed out of the way. This is extremely unlikely and only possible in “certain” types of multiverse so it may as well be impossible to test. On top of that even IF we were to find such a “cold-spot” it’s not even necessarily from such an event as it could be explained away as large quantum fluctuations being exponentially expressed in matter spread as the universe expanded.

The number of configurations of particles in accordance with the periodic table is limited; incomprehensibly huge, but still limited, and if the universe actually is infinitely large, then every configuration is being calculated out in real time, meaning that everything that CAN happen, IS happening somewhere else, even within the same universe, let alone a full-on multiverse.

There are types of multiverse where it would be possible to observe the effects of another “universe” forces like gravity could leak across from other dimensions (a possible cause of dark matter), edge effects from other “universes” which share some coordinates in say spacial dimensions with our observable universe have been proposed a lot of them would be visible with gamma ray astronomy. One way of looking at it is we could be in the same position as someone proposing a heliocentric solar system with stars being other suns before the invention of the telescope. We can’t just look up and see the moons of Jupiter orbiting it, we can’t measure angles in the sky finely enough to observe parallax and get an idea of the distance to the sun etc etc.
