That is the title of an article I wrote 5 years in the past. Sure, it is a provocative headline, however it’s additionally right — or no less than as correct as you will get when making use of practical science to a fictional character.
In March 2016, Henry Cavill had performed Superman in two movies, Man of Metal and Batman v Superman, and it is potential that Zack Snyder’s Justice League (AKA ‘the Snyder Lower’) may very well be Cavill’s ultimate outing because the final son of Krypton.
With current rumors suggesting Warner Bros will forged a black actor because the subsequent Man of Metal, it is the fitting time to revisit the science behind why Superman ought to have darkish pores and skin, and why some folks did not perceive the reasoning.
Superman is sort of a plant
Superpowers break the legal guidelines of physics, however explaining why particular skills are not possible is not any enjoyable, so I explored the believable.
The essential premise is that Superman is fuelled by daylight and, as talked about in Man of Metal, his cells take in photo voltaic radiation.
In nature, organisms equivalent to crops do one thing related via photosynthesis. Plant cells seize photons in gentle utilizing a inexperienced pigment, chlorophyll, inside buildings referred to as chloroplasts that energy chemical reactions to generate power.
However Superman would not be inexperienced as a result of, not like crops, he is not from Earth — he is an alien from planet Krypton. His ancestors advanced on a world orbiting a dying star that radiated much less gentle. For his or her cells to soak up radiation, they would want a darkish pigment to seize a broad spectrum of wavelengths in gentle.
As NASA space-scientist Nancy Kiang stated within the Scientific American article that impressed my Superman story, “Evolution would possibly favour a higher number of photosynthetic pigments to pick the total vary of seen and infrared gentle. With little gentle mirrored, crops would possibly even look black to our eyes.”
So in a believable situation, Superman’s pores and skin would comprise a pigment that works like chlorophyll however seems black in color.
Pigments have completely different capabilities
Some folks appeared confused by the reason. However whereas it might be simple to dismiss them as silly, as a science communicator I am within the public understanding of science, so I attempted to pinpoint the supply of their confusion.
Forbes articles used to incorporate a remark part and, after studying about 100 feedback, I managed to determine a typical theme — some folks did not perceive that Superman may very well be stronger as a result of darkish pigments would take in extra power. That is summarised within the following assertion from ‘Joey’:
“That is the exact opposite of actuality. Darker pigmentation blocks out the Solar which might make him weaker.”
So the misunderstanding comes from the idea that pigments can solely have one operate: to dam gentle. You’ll be able to perceive why some folks have been confused as people and different mammals use numerous pigments — collectively generally known as ‘melanin’ — to forestall photo voltaic radiation (particularly UV gentle) from inflicting mutations that harm the DNA in cells. Melanin pigments assist shield us in opposition to pores and skin most cancers.
Folks did not perceive that pigments can have completely different capabilities. They have been unable to make a distinction between one which blocks gentle — melanin — and a pigment that absorbs gentle, like chlorophyll, besides black as an alternative of inexperienced.
The misunderstanding displays an mental error typical of people that do not actually perceive biology: we’re just one a part of nature. When non-biologists view the pure world, they deal with people, an ‘anthropocentric’ perspective. It is a mistake lecturers have made when making an attempt to outline ‘life’, as an example.

Shade will not be at all times about race
‘Science Says Superman Ought to Be Black’ went viral and obtained optimistic protection on information websites and social media.
Reactions on Twitter made some legitimate factors (“if science utilized to superman he wouldn’t be capable to fly”) and tongue-in-cheek jokes (“His actual title is Kal-El. That already sounds black.”)
My article clearly touched on points related to race, so I additionally obtained destructive suggestions, together with feedback that contained racist language or informal racism attributable to unconscious bias.
As one commenter stated, “Whereas we’re at it, let’s make Superman homosexual as properly.” That assertion has a number of interpretations, equivalent to the very fact some folks don’t need change for change’s sake, however I think ‘Matt’ was really accusing me of being a Social Justice Warrior engaged in what’s now referred to as “advantage signalling.”
The Superman piece stays certainly one of my hottest articles — it had over 300,000 views by 2018 so I would estimate it is now been seen about half one million instances.
However over the previous few years, I’ve written dozens of options on the science or expertise behind superhero motion pictures. My favorite is an unpopular piece on the cultural affect of Black Panther in creating position fashions.
Over the previous few a long time, comedian books have featured superheroes whose secret id has switched from man to lady, most famously with a feminine Thor (who shall be performed by Natalie Portman within the forthcoming Marvel Cinematic Universe film, Thor: Love and Thunder).
Importantly, it is the key id that modified, not the character’s title. I am not satisfied that followers would settle for a ‘black Peter Parker’ as readily as ‘Miles Morales, Spider-Man‘, however I may very well be fallacious. Samuel L Jackson portrayed Nick Fury, director of SHIELD, however he is a minor character — not a significant icon.
Assuming that Superman’s origin story consists of being brought-up on a farm in Kansas by white mother and father, a ‘black Clark Kent’ would possibly seem to be a step too far.
5 years since writing my article, I nonetheless cannot consider scientific argument in opposition to why Superman needs to be black.
