A heap of cool scientific discipline happened in 2016 , but the obvious “ holy shite ! ” moment came when physicists announce they ’d confirmed the existence of gravitational wave , ripples in the material of spacetime first predicted by Albert Einstein in 1916 .

Of of course , some common people had other things to do last year besides geeking out about science all over the internet every mean solar day ( I do n’t know these masses , but I assume they live ) . If you miss one of the most exciting physics developments of the century , or take a refresher on what gravitational waves are , why we care and how we detect them , this nine moment spiritedness by YouTube’sDominic Wallimandoes not let down .
Even as someone who observe the first detection of gravitative waves obsessively ( I assist a press group discussion on the announcement in Washington DC , where I had the delight of hearing Kip Thorne apply the idiomatic expression “ violent storm on the cosmic ocean ” ) I found Walliman ’s take to be chock full of interesting fact , figures , and comparisons , including :
1 . In the span of 0.2 seconds , the black hole collision that raise humanity ’s first bonafide gravitative wave signal released more vim than all of the stars in the known world .
2 . In the sentence it took said gravitative waves to get through our planet , spirit cower out of the sea and onto the state , dinosaur evolve and died , and human race because a prevailing drive forcefulness on Earth .
3 . The Laser Interferometer Gravitational Wave Observatory ( LIGO ) is far more than a black kettle of fish demodulator . Studying gravitational waves could help scientists hone mensuration of how quickly the universe is expand , how much moody energy is really out there , and why star go supernovae .
But do n’t let me give it all out . mark off out the television for yourself , and spend 2017 impress everybody with your knowledge about the hot new limb of astrophysics .
