      I’m by no means an expert of parallel universes (which means I’m more than happy for someone else to correct me on this!), but I think the idea behind parallel universes is that it is physically impossible to travel, send a message, or even observe or measure anything outside our own universe: So we’d have no way of knowing if they exist, and if they do what they are like – the idea of multiple parallel universes is more of a thought experiment.

      I don’t think it’s ever possible for us to know if they exist, and if they were, we wouldn’t know how they are parallel because the laws of physics would be different in each one!

      There’s been quite a lot of talk about the Multiverse theory – I presume that counts as good evidence that they exist though!
