Nerd Fight!: Physicist Brian Cox Corrects Neil DeGrasse Tyson On The Physics Of Lightsabers

February 9, 2016

This is an interview between Neil DeGrasse Tyson and physicist Brian Cox in which Brian explains to Neil that lightsabers actually could bounce off each other, despite being made of light (previously Neil argued they would just pass through each other with no interaction). Then they whip out two plastic lightsaber replicas and try to beat each other senseless. Just kidding, that's only what I was hoping would happen. It's like that Rolling Stones song -- you can't always get what you want, but if you try sometimes you just might find, you get the exact opposite, and that is life, the end.

Keep going for the video and learn science.

Thanks to n0nentity, who wants a hula hoop shaped lightsaber.

    How is no-one bringing up the point that lightsabers are magnetically contained plasma.

    Clue is in the name; "Lightsaber."

    No, NDT might not be conducting scientific experiments himself. However, he is doing the job of making science easier to understand for the masses. Never before in American history have we had such a rabid strain of anti-scientific belief. Science, facts, and logic are no longer enough to settle debates. Debates can no longer be won since, if certain science goes against someone's beliefs, they somehow have convinced themselves that they can choose not to believe it.

    NDT is using his celebrity to spread scientific awareness. He is fighting the good fight. He's become America's science teacher. Anyone who hates on that is sipping hatorade at near lethal levels.

    Yes to this. Neil was the perfect choice to pick up the mantle after Carl Sagan.

  • G-man

    I just masturbated to this.

    Maybe if he knew anything about Star Wars, he would know that Lasers and Lightsabers are NOT lasers beams.

  • Andyman7714

    It sounds like the power level that they are talking about would melt your face off just holding the blasted thing.

    Eh. I have always thought that NDT is overrated. Seems like he just loves the sound of his own voice.

    Is there a shit-eating-grin particle?

  • Pwnsauce

    No just the bohrs-english-teething particle

    They still wouldn't collide like solid objects, because there is no lattice there to absorb recoil. Instead, what you're going to get in that scenario is a powerful flash of scattered gamma radiation as the two swords cross. It'd be less of a Star Wars saber fight scenario, and more of the Ghost Busters' "Don't cross the beams," scenario.

    NDT stopped sciencing years ago; he has graduated* to guy-on-TV talking about science. Still, a rich man's Bill Nye.
