We might have noticed a parallel universe going backwards in time

Unusual particles noticed by an experiment in Antarctica could possibly be proof of another actuality the place every part is the wrong way up

IN THE Antarctic, issues occur at a glacial tempo. Simply ask Peter Gorham. For a month at a time, he and his colleagues would watch a large balloon carrying a group of antennas float excessive above the ice, scanning over one million sq. kilometres of the frozen panorama for proof of high-energy particles arriving from area.

When the experiment returned to the bottom after its first flight, it had nothing to point out for itself, bar the odd flash of background noise. It was the identical story after the second flight greater than a 12 months later.

Whereas the balloon was within the sky for the third time, the researchers determined to go over the previous knowledge once more, significantly these alerts dismissed as noise. It was fortunate they did. Examined extra rigorously, one sign appeared to be the signature of a high-energy particle. But it surely wasn’t what they had been searching for. Furthermore, it appeared inconceivable. Slightly than bearing down from above, this particle was exploding out of the bottom.

That unusual discovering was made in 2016. Since then, all types of recommendations rooted in recognized physics have been put ahead to account for the perplexing sign, and all have been dominated out. What’s left is surprising in its implications. Explaining this sign requires the existence of a topsy-turvy universe created in the identical huge bang as our personal and present in parallel with it. On this mirror world, constructive is unfavourable, left is true and time runs backwards. It’s maybe probably the most mind-melting thought ever to have emerged from the Antarctic ice ­­– but it surely would possibly simply be true.

The ambitions …
