As usual, the dear old Beeb used eye-catching visuals to piss our scientific heritage up the wall when it threw together this junk. Theories of multiple universes beyond our own and mostly beyond our ken have been around for some time. The subject is complex, stretching over various disciplines from abstruse physics and cosmology to science fiction, where of course it begins and ends like the mythical Ouroboros.
But as any fule kno, multiple universe conjectures are not theories in the scientific sense, simply because they are not testable experimentally. Theories you can’t prove derive their impact from professional chic, dinner-table kudos, book sales, silly TV programmes and social chit-chat. Apart from these essentially social and professional uses, they may as well be dismissed as the garbage they really are. How do I know? Partly because there is no such thing as a multiverse detector and partly because my metaphysical crap-detector tells me so. Sometimes there really is no better way to get a grip on these things.
Too many scientists just don’t get it. Science is supposed to be enlightening – the multiple universe is a dose of darkness we don’t need.
