How To Flashing reach axis rd62
super speeders are everywhere these days.there’s the flash and quicksilver and that other quicksilver that isn’t the first quicksilver(let’s not get into that). we know that they all use their powers to zip around fightingbad guys but what i want to know is how they listen to music. more specifically i want to know how we arehearing anything at all in the coolest scene of x-men: days of future past present pastfuture participle. what makes this quicksilver scene so greatis obviously the awesome slow-mo effects but also the fact that the audience is taken alongfor the ride with help from quicksilver’s song of choice. but think about this for asecond. how is he hearing music at a normal
speed in the span of the few millisecondsthe whole scene actually takes? at first i thought this was a question ofrelativity. i thought that the music could play at the normal speed because the walkmanwas attached to quicksilver’s hip and moving at the same speed that he was, so there’d beno weird time dilation or doppler effects with the music. you can test this by falling from space. remember when felix baumgartner raised himselfhigh up into the atmosphere in a capsule and then stepped out to fall back to earth? well,i do. it was cool. when felix baumgartner dropped from the edgeof space, his falling body broke the sound
barrier. he was moving beyond the speed ofsound but he could still hear himself speak. this is because the air in baumgartner’shelmet was moving with him at the same speed. and we can assume quicksilver is in the samesituation. quicksilver’s headphones keep pockets ofair inside of his ears that move along with him, so thankfully we can ignore any weirddoppler effects or the deafening rush of air itself.so if we aren’t dealing with weird time distortions or doppler shifts, how can quicksilverlisten to his music in that scene? time for some math. first how long does quicksilverhave to save erik and charles? well the guards in the film are firing whatlook to be magnum revolvers, which have muzzle
velocities of around 450 meters per second.and of course the internet has already estimated the distance between the guards and our x-men(link in the show notes), and it’s about 2.6 meters or so.so, with a bullet moving at that speed across that distance it would give our heroes about0.05 seconds to be saved by quicksilver, or about five times as fast as human reactiontime. now for the music.looking back, the whole quicksilver scene looks to last about 110 seconds, and in thattime quicksilver listens to the majority of the song on his walkman equivalent.finally, to listen to 110 seconds worth of music in only 0.05 seconds of real-time, quicksilverwould have to adjust his player to play at
1,800 times normal speed.now let’s assume for a second that this is actually possible, and that quicksilver’swalkman wouldn’t tear itself apart under these tens of thousands of rpm (which it totallywould). how does quicksilver even understand 110 seconds worth of music in the time ittakes for a normal person to actually understand that they’re even listening to music?!remember way back when to my very first because science video on how the flash can actuallyperceive more of time that we can? i think quicksilver has to operate the same way.for the same reason that time seems to slow down for quicksilver, a song playing in hishead will as well no matter the speed. he has a higher “frame rate†than us, hecan sample more of the world than we can.
that is to say you could play a song backto quicksilver at any speed and his brain would give him the auditory resolution tohear it correctly. so, the only reason that quicksilver can understandauditory information coming off a cassette tape going at 50 to a 100 thousand rpm isthat his brain can process information as quickly as he runs. at least we got to seethe totally awesome slowed-down version of that, and not the version where his clothesare blown off instantaneously by wind resistance, cuz that would totally happen. why? becausescience. want more science? check out my last videoon when we’re gonna run out of oil like mad max. subscribe to nerdist for more videos. if you want because science two days earlier than anyone else,
