>>8349873They'll find zero evidence of parallels. IF infinite parallel universes exist, as some versions of unifying theories of physics predict, than nothing in these parallels can interact at any level with our own universe, because any interaction (no matter how small) would be similarly infinite summed over all parallels. I'm reminded of Michelson and Morley's conclusions about the "luminiferous aether" when they set out to find evidence of its existence only to confirm that it either A) didn't exist or B) existed but didn't interact with the observable universe in any way... which for all intents and purposes was the same as not existing at all.
None of our existing findings so far have supported the multiverse theory - the Higgs Boson was discovered to have a mass which is neither consistent with mutliverse nor supersymmetry theory, and neither has made any other successful predictions so far. In all likelihood our existing models on a Grand Unifying Theory are all wrong, which isn't a bad thing because it means there's still interesting physics to be discovered and whatever does turn out to be the correct model will probably be something far more interesting and elegant.
tl;dr - this experiment will find nothing and physicists theories on GUT are likely wrong
