Traveling faster than the amphetamine of light in a void is impossible , according to Einstein ’s possibility of special relativity theory .
Particles without mass must travel at the speed of light , while any other object cursed with great deal finds that it can not approach 299,792,458 metre per 2nd ( 983,571,056 feet per mo ) without expendinginfinite amounts of energy . Physicists and sci - fi writer have adjudicate to get around this , with concept like thewarp private road . But likely these will work out to be forbidden by those bothersome laws of physics , given that any faster - than - lighter travel can take touniverse - breaking paradoxes .
However , there is something in the room with you in good order now that can break the speed of light , take on you are not sat in a dark room . shadow are capable to exceed the speed of light – and absolutely smash it , in fact .
Shadows still move at the speed of light.Image Credit: Falsedef viaWikimedia Commons(CC BY-SA 3.0)
You may have questions , such as " what the hell on earth are you speak about ? " . think you have a Aaron’s rod brawny enough to light up the moon to some extent . Pass a finger across the front of the torch quickly , and the shadow your finger mould can move across the lunar surface at speeds far in excess of the speed of Inner Light .
The same sort of musical theme can be accomplish by simply flap a laser across the night sky . If you ideate a giant attic place ( to pick a number ) 100 light - years across surrounding you , when this optical maser hit it 100 long time in the future the points will whiz across the dome at amphetamine far go past that of ignitor .
But both these examples are just illusions .
" Just the mental image of the electron beam as it races across the night sky is moving faster than light , but there is no message , no net information , no material object that actually moves along this image , ” astrophysicist Michio Kaku explained in theBig Think .
The optical maser point is not really moving per se – what you are figure is the photons hitting the bean , shortly followed by different photon hitting a dissimilar part of the attic after you proceed your laser 100 twelvemonth in the past .
Nothing really motivate faster than light , and no entropy was transferred , leaving the universe and cathartic intact .
