That is the title of an article I wrote 5 years in the past. Sure, it is a provocative headline, nevertheless it’s additionally right — or not less than as correct as you may get when making use of lifelike 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 attainable that Zack Snyder’s Justice League (AKA ‘the Snyder Minimize’) might 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 correct time to revisit the science behind why Superman ought to have darkish pores and skin, and why some individuals 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 fundamental premise is that Superman is fuelled by daylight and, as talked about in Man of Metal, his cells take up photo voltaic radiation.
In nature, organisms corresponding to crops do one thing comparable by way of photosynthesis. Plant cells seize photons in mild utilizing a inexperienced pigment, chlorophyll, inside constructions known as chloroplasts that energy chemical reactions to generate power.
However Superman would not be inexperienced as a result of, in contrast to crops, he isn’t from Earth — he is an alien from planet Krypton. His ancestors advanced on a world orbiting a dying star that radiated much less mild. For his or her cells to soak up radiation, they would want a darkish pigment to seize a broad spectrum of wavelengths in mild.
As NASA space-scientist Nancy Kiang mentioned within the Scientific American article that impressed my Superman story, “Evolution would possibly favour a larger number of photosynthetic pigments to pick the complete vary of seen and infrared mild. With little mild 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 totally different features
Some individuals appeared confused by the reason. However whereas it will be straightforward 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 standard theme — some individuals did not perceive that Superman might be stronger as a result of darkish pigments would take up 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 perform: to dam mild. You’ll be able to perceive why some individuals have been confused as people and different mammals use varied pigments — collectively often called ‘melanin’ — to forestall photo voltaic radiation (particularly UV mild) from inflicting mutations that harm the DNA in cells. Melanin pigments assist defend us in opposition to pores and skin most cancers.
Folks did not perceive that pigments can have totally different features. They have been unable to make a distinction between one which blocks mild — melanin — and a pigment that absorbs mild, 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 concentrate on people, an ‘anthropocentric’ perspective. It is a mistake lecturers have made when attempting to outline ‘life’, for example.

Colour shouldn’t be all the time about race
‘Science Says Superman Ought to Be Black’ went viral and acquired 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 identify is Kal-El. That already sounds black.”)
My article clearly touched on points related to race, so I additionally acquired adverse suggestions, together with feedback that contained racist language or informal racism attributable to unconscious bias.
As one commenter mentioned, “Whereas we’re at it, let’s make Superman homosexual as nicely.” That assertion has a number of interpretations, corresponding to the actual fact some individuals don’t desire change for change’s sake, however I think ‘Matt’ was truly accusing me of being a Social Justice Warrior engaged in what’s now known 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 occasions.
However over the previous few years, I’ve written dozens of options on the science or know-how behind superhero motion pictures. My favorite is an unpopular piece on the cultural impression of Black Panther in creating position fashions.

Over the previous few many years, comedian books have featured superheroes whose secret identification has switched from man to girl, most famously with a feminine Thor (who can be performed by Natalie Portman within the forthcoming Marvel Cinematic Universe film, Thor: Love and Thunder).
Importantly, it is the key identification that modified, not the character’s identify. I am not satisfied that followers would settle for a ‘black Peter Parker’ as readily as ‘Miles Morales, Spider-Man‘, however I might be unsuitable. Samuel L Jackson portrayed Nick Fury, director of SHIELD, however he is a minor character — not a serious icon.
Assuming that Superman’s origin story consists of being brought-up on a farm in Kansas by white dad and mom, a ‘black Clark Kent’ would possibly seem to be a step too far.
5 years since writing my article, I nonetheless cannot consider a superb scientific argument in opposition to why Superman must be black.
