Some guys at my alma mater have apparently come up with an experiment to collide two photons and produce an electron and a positron. So where did matter come from? Light, clearly.

gftChris Posted May 20, 2014 Author Report Share Posted May 20, 2014 Not sure about destroyed. This is a theoretical experiment dreamt up in 1934 - we've only just figured out how we can conduct the experiment, and are attempting to prove it.

VaporTrail Posted May 21, 2014 Report Share Posted May 21, 2014 So now matter can be created and destroyed? WSS No. There's an equation that some guy you may have heard of derived in the 1900's which supports this. Link to comment Share on other sites More sharing options...

gftChris Posted May 21, 2014 Author Report Share Posted May 21, 2014 Conservation of mass or energy or something I'm not sure about. .... (IOW no fucking clue. . ) WSS Presumably the light energy would be transformed to heat energy, making these particles extremely hot. We've known for a while from the double slit experiment (I think?) that light can behave like a particle as well as a wave, in the same way that matter can, so light becoming matter I guess makes some sort of sense? Either way, cool stuff, it could go some way to answering the 'where did matter come from?' questions relating to the big bang once and for all, without saying "this is our best guess currently" Link to comment Share on other sites More sharing options...

gftChris Posted May 21, 2014 Author Report Share Posted May 21, 2014 To shed a little light on the subject, "what does it matter now?" 85./10 Not bad, but if you'd just gone with something like: "Hopefully it'll shed a little light on the matter" You would have got a 10/10.

VaporTrail Posted May 21, 2014 Report Share Posted May 21, 2014 So the equation that governs this is E=mc2 E = energy m = mass c = speed of light It basically means that mass is energy. We can actually do the opposite of this right now via positron electron annihilation. Link to comment Share on other sites More sharing options...

MLD Woody Posted May 22, 2014 Report Share Posted May 22, 2014 Those solar roadways are awesome. Too bad it would take forever for something like this to get implemented through pur govt. Traditional energy lobbies won't have it and Congress will follow the money. Link to comment Share on other sites More sharing options...
