Can't prove anything about these topics:-http://blogs.scientificamerican.com/life-unbounded/does-a-multiverse-fermi-paradox-disprove-the-multiverse/?WT.mc_id=SA_DD_20150623-"If reality is actually composed of a vast, vast number of realities, and if ‘anything' can, does, and must happen, and happen many, many, times, this presumably has to include the possibility of living things (whatever they're composed of) skipping between universes willy-nilly. After all, just because physics in our universe makes that look kind of tricky, it doesn't prevent the physics of a huge number of other universes from saying ‘sure, go right ahead!'-"And there's the rub. Discounting our all-to-human capacity for self-delusion, there is absolutely no hard evidence that we are being, or ever have been, visited by stuff from other realities. (And really, if you do feel inclined to comment and tell me I'm wrong about that, save your breath, sorry)."
