Because, from next month, you will be able to buy one of these – a make-your-own-universe kit. It’s based around some fancy science that states there are an infinite number of possible alternate universes, and more are created each time any kind of measurement is taken that defines one particular place. Or something along those lines. Hopefully someone who understands these things and has a degree will be along shortly to explain it properly in a comment.
But it is obviously not real. The multiverse-maker is the work of conceptual artist Jonathon Keats, who’s used some fancy uranium-fused glass to create something to do with measuring streams of alpha particles. It’s all a bit complex, to be honest. But will make a superb Christmas present for any of you who have scientifically-minded dads.
