So, apparently the concept in the game where entering the wormhole was detected to always resulted in the traveller arriving millionths of a second *before* departing is actually real as far as real world quantum physics has shown and has been known for several decades.
> What one finds is that the photon actually arrives far earlier than that. In fact, it arrives so early it appears to have spent a negative amount of time inside the cloud – to exit, on average, before it enters.
And new research has successfully measured this strange phenomenon! Read this article to learn more (it's also where the above passage is quoted from).
