You Must Not Trust Experiments That Claim The Existence Of Parallel Universes

The Universe is out there, waiting for you to discover it.

Is there another Universe out there? The Universe we know and inhabit, the one that began at the start of the hot Big Bang, might not be the only one out there. Perhaps one was created at the same time as ours was, but where time runs backwards instead of forwards. Perhaps there are an infinite number of parallel Universes out there, spawned by an eternally inflating Universe. Or, as has been in the media lately, perhaps there's literally a mirror Universe out there, where the particles we know of are replaced with an exotic version of themselves: mirror matter. 

Most scenarios involving parallel Universes like this are untestable, as we're restricted to living in our own Universe, disconnected from any others. Yet if one particular idea is right, there might be an experimental signature awaiting our investigations. But even if it yields positive results, you shouldn't trust it. Here's why. 

Whenever you have an experimental or observational result you cannot explain with your current theories, you have to take note of it. Robust measurements that defy the expectations of our predictions might turn out to be nothing — they might go away with more, improved data — or they might simply be errors. This has famously been the case many times, even recently, such as with

• the BICEP2 collaboration's claimed detection of gravitational waves from inflation,
• the faster-than-light neutrinos claimed from the OPERA experiment,
• or with the diphoton "bump" claimed as evidence for a new particle a few years ago at the LHC.

 

In all these cases, there was either an error with the way the team did the analysis or attributed the signal's components, an error in the experimental setup, or the observed effect was simply a random statistical fluctuation.

 

This happens. However, sometimes there are results that really do appear to be puzzles: the experiments shouldn't turn out the way they did if the Universe works the way we think it does. These results often turn out to be omens that we're about to discover new physics, but they also frequently turn out to be red herrings that lead nowhere. Even worse, they can turn out to be duds, where they only appear to be interesting because someone, somewhere, made an error.
