Superheroes are super in every sense of the word. They fight evil, look great and even have fantastic hair – with the exception of Wolverine perhaps and oh, they also save humanity at the end of the day. The only non-super thing about them is that they're not real, but being limited to the realm of fantasy may not be as permanent a thing as most of us believe.
A Stanford scientist recently sat down to explain the science behind Marvel characters, The Hulk and Captain America. The extravagant abilities given to these superheroes for cinematic benefits make us think that these fictional beings have no scientific basis to exist, but you'll be surprised how much sense a scientist can make of it.
This is exactly what Biology Postdoctoral Research Fellow Sebastian Alvarado did. He offered two possible explanations for the Hulk's ability to bulk up into a behemoth. According to him, the eternally angry character's DNA probably went through chromosomal shattering or chromothripsis when he was exposed to high levels of gamma radiation.
But what about his ability to transform back into his actual Bruce Banner self? Alvarado has a scientific justification for that as well. He believes possessing that trait for a human is theoretically possible too, thanks to something called epigenetic modification. It basically gives the Hulk the ability to control his powers. Think of it as a power switch which can be turned on and off at will.
Here is Alvarado speaking his mind on the subject:
He analyzed Captain America's superhuman powers the same way as well, and revealed that drugs such as the one that gave an average Steve Rodgers a perfect human body aren't as farfetched an idea as we think.
