EvenElon Muskthinks his space - cruising midnight - cherry Tesla Roadster look uncanny .
" It look so cockeyed and impossible , " theSpaceXCEO tell reporters after the Falcon Heavy megarocketlaunched the car into spaceyesterday ( Feb. 6 ) . " you may severalize it ’s real because it looks so fake , candidly . "
This Tesla sure looks fake, but that’s because of the way colors appear in space. On a side note, Elon Musk told reporters that, “If you look closely on the dashboard, there’s a tiny roadster with a tiny spaceman."
Musk went on to say that colors , in general , appear strange in space , because " there ’s no atmospheric stoppage . Everything ’s too crisp , " he said . But what did he mean by this , and is it true that coloring material in quad do n’t look the same as they do on Earth ? [ The 18 Biggest Unsolved Mysteries in Physics ]
First off , yes — colors do look " fuzzed " on Earth than they do in place , state Rick Sachleben , a retire chemist in Boston who is a member of the American Chemical Society ’s gore of experts .
reckon of it this way : Light can move through unlike mediums — include air , water and the vacuity of space — each of which has a dissimilar refractive index , he say . That is , these medium turn light otherwise , which explains why colored igniter does n’t look the same in one medium as it does in another .
Furthermore , when abstemious travels through the Earth ’s atmospheric state , it slip by through air that contains molecule , such asdust , carbon black , smokeand liquid droplets . The air travel also has vary densities depending on how much pee it contain and its temperature , Sachleben aver . For instance , the air at the top of Mount Everest is less slow than at ocean degree , which is why breathe at Everest ’s peak is challenging .
These factors — tune ’s particle and properties — can change the way colors reckon on Earth , Sachleben told Live Science .
" The luminousness disperse off of those speck , " he said . " When it hits a opus of detritus , it bounces off of it . And then it hits another one , and itscatters off of that one . " That ’s why " the image we see [ on Earth ] is fuzzier , less trenchant , " he said . " In infinite , you do n’t have that . "
In space , there ’s just anything to bend or obstruct light . That ’s why pictures taken by theHubble Space Telescopeare so much sharper than prototype taken from worldly concern - base scope , Sachleben said .
" You get these unbelievably good pictures when you ’re in space , " he said . Other look-alike snapped in space , such as the famous " Blue Marble " exposure , also show clean and frizzly colors . But perhaps people did n’t see it , because these images were n’t as crazy - depend as aTesla Roadster heading toward the asteroid whack , Sachleben noted .
Because colour in space looking so sharp , pictures and videostaken there may look as if someone visually delete them . This is likely why Musk joke that the Roadster images looked " fake , " Sachleben said .
However , Sachleben noted that he ’s never hear of " atmospheric occlusion , " the full term Musk used . It ’s potential that Musk was referring to atom in Earth ’s air travel that block and spread lighter , but it ’s punishing to say for sure , Sachleben say .
" It ’s in all likelihood [ Musk ] speak off the cuff and using terminology that ’s not necessarily incorrect , but not standard , " Sachleben said .
SpaceXdidn’t immediately respond to a request for input , but hot Science will update the floor if the company responds .
