I think we can all agree that, given the option, we'd love to be the owner of a lightsaber. Conceived by the father of Star Wars, George Lucas, back in 1977, the fictional energy weapons have became one of the most iconic weapons in cinematic history.
Ever since their first appearance in A New Hope, a lightsaber battle has appeared at least once in every Star Wars film to date. With devastating power capabilities, it seems like no material or substance can mount a defense against a lightsaber except for another lightsaber — which has lead many to ponder, could we theoretically produce one?
Cue American Astrophysicist Neil deGrasse Tyson And British Physicist Brian Cox
It all started way back in 2013 when Neil deGrasse Tyson debunked the idea that lightsabers could duel like metal swords. The astrophysicist branded them useless as a defense, and as many would agree, if Neil deGrasse Tyson says it, it must be right. Well, not if your Brian Cox. The British physicist had a retort that gave millions of fans hope!
Although these tweets where from a long time ago, in a galaxy er — well in our galaxy, the duo sat down to further discuss the possibility of lightsabers. Speaking on Neil deGrasse Tyson's radio show, Startalk, Cox outlined how he had actually studied a process called "photon-photon or gamma-gamma scattering" which would prove that lightsabers could duel like swords.
What Brian Cox discusses is the idea that if lightsabers were real, they would be made out of super high-energy light. This would then create a large cross section where they could bounce off of each other instead of passing through each other like deGrasse Tyson theorized.
Incredibly, Brian Cox also mentions that this phenomenon has been observed in particle accelerators, meaning it's not merely just a theory!
TL;DR: LIGHTSABERS ARE REAL!
