Ghostbusters: 7 Scientific Facts To Make You Hate It Less

7. Proton Packs

Simply put, those proton packs are miniature particle accelerators, just like the Large Hadron Collider.

The packs were updated slightly for the 2016 version, replacing the cyclotron with a synchrotron, But the principle remains the same: They fire out a powerful stream of protons and nuclear energy to capture the ghost.

As ghosts are apparently made up of "Psychokinetic Energy", which consists of electrons, neutrons and ectoplasm, this would make them negatively charged (although we don't actually know the charge of ectoplasm, a ghost made of "negative energy" is canonically fitting). The positively charged protons in the proton pack trap the negatively charged electrons like a statically charged balloon sticking to your head and, boom, you've caught a ghost.

The Proton Packs are actually remarkably scientifically sound, apart from the whole trapping-the-wandering-souls-of-the-dead thing, and of course the fact that they occupy the size of a backpack, as opposed to several miles of the France/Switzerland border.
