Go outside and you will be showered , every Clarence Shepard Day Jr. , with proof of the hypothesis of peculiar Einstein’s theory of relativity . This proof come in the form of muons , so you wo n’t in reality see it , but we ’ll tell you why the presence of these corpuscle proves Einstein ripe .
The theory of special theory of relativity is n’t controversial anymore . It ’s no surprisal that many find it arduous to trust . The idea that clip can be stretched and compact for people going at different speeds is concentrated to accredit . When scientists started think about it , though , they realized that the hypothesis had a lot ofeasily - discernible test copy .

As scientists observed they universe , they change by reversal up more and more test copy . One of the biggest proofs comes from one of the smallest physical object in the universe . The muon is n’t as small as an electron or a neutrino , but it ’s still smaller than any other particle of matter . Its small size is a reliever , as the Earth is rain cats and dogs with a portion of muon every daytime . Cosmic electron beam hit the atmosphere and create muons aviate towards the ground . The muon do n’t overstay their welcome . The muon lifespan is about 2.2 microseconds . After that , it decay into an electron and a neutrino .
The muon created in the upper air are moving at about 99 percent of the speed of light . That ’s not enough . A muon move around at 99 percent of the velocity of light for 2.2 microseconds will decay long before it collide with Earth ’s surface . Only a few very , very golden and long - live muons will mint the Earth .
Despite this , we are constantly being inundated in muons . Nearly 10 percent of the muons that get created make it down to us . The mystery to that otherwise - unaccountable wealth of particles is special relativity . The muons are proceed so fast , relative to us , that their 2.2 microsecond of life lasts , from our perspective , 15.6 microsecond . If we were the muon , we ’d still be experience only 2.2 microsecond , but all of us here on Earth see the subatomic particle living 15.6 microseconds , and come down to bash us on our heads .
We are literally struck with evidence of special relativity every day .
