In Star Wars: A New Hope, Obi-Wan Kenobi describes the Drive as, “an vitality discipline created by all residing issues. It surrounds us and penetrates us; it binds the galaxy collectively.”
It’s a extra poetic clarification than the one in Star Wars: The Phantom Menace, which suggests that each Jedi has a nasty case of worms. Or, to be extra exact, that they get their powers from microscopic mobile beings known as midi-chlorians.
“The concept that a parasite residing in a creature may change or decide the best way the host behaves is a really actual factor,” says Patrick Johnson, creator of The Physics of Star Wars.
“And in concept, that small creature may give the host the power to do issues that they won’t in any other case be capable of do.”
A concept that makes extra sense to Johnson, although, is that the Drive represents some type of subtle management of electromagnetic fields.
“The basic foundation of electromagnetic fields is that all the pieces that has a cost (equivalent to protons and electrons) creates an electromagnetic discipline round it,” says Johnson. “And relying on how these particles work together, they will both appeal to or repel each other.”
This might clarify how Jedi equivalent to Ahsoka Tano – the hero within the new collection Star Wars: Ahsoka – are in a position to transfer objects round, says Johnson. “So, for example, if I’m hanging upside-down in an ice cave on Hoth and I want my lightsaber, in concept I may make my hand very positively charged to draw the electrons on one facet of the lightsaber and pull it in direction of me.”
However, even when this have been potential, it will additionally require you to have the ability to deal with a selected object. “In any other case, you’ll find yourself attracting every kind of issues,” says Johnson.
Probably the most highly effective components of the Drive, nonetheless, is how it may be utilized by the Jedi to manage others’ minds. How do electromagnetic fields play into that?
“By way of Jedi thoughts methods,” says Johnson, “our brains have neurons that talk with each other utilizing electrical indicators.
“Theoretically, a Jedi with data of mind chemistry may exert very exact electromagnetic fields to trigger sure neurons to fireside or not. Let’s say the thought ‘that is the droid I’m in search of’ is neuron one and ‘this isn’t the droid I’m in search of’ is neuron two. If I may cease neuron one from firing and trigger neuron two to fireside as a substitute, that will then create that thought inside your head.”
Johnson is eager to emphasize that this sort of thought management is very inconceivable. There are 86 billion neurons within the human mind and, “it will be very troublesome to execute such a exact manipulation of particular person neurons – or to determine what neurons you would want to manage. It could require you to map an individual’s mind to a degree that we’re presently not able to.”
Even so, that doesn’t imply that scientists aren’t attempting. Johnson references a 2008 examine during which researchers requested contributors to hit a button with both their proper or left hand whereas recording their mind exercise.
“The researchers have been ready to determine what the mind exercise would appear like simply previous to the themes urgent the button with their left hand versus their proper,” says Johnson.
“Even stranger, they have been ready to make use of this exercise to foretell which hand was going for use as much as seven seconds earlier than the individual made their alternative.”
So, perhaps there’s one thing to the entire midi-chlorians factor in spite of everything.
