Physics of The Hulk

Rhett Allain berechnet auf Wired die physikalischen Eigenschaften des Hulks. Eigentlich geht's laut der Headline um "Hulks Jump", aber der Teil über die Dichte von Bruce Banner finde ich toller, in dem er ausrechnet, dass Banner während der Verwandlung in den Hulk entweder die Solarenergie des kompletten Planeten benötigen würde und die Mutation dann immer noch zweieinhalb Minuten dauern würde, oder aber dass der Hulk die Dichte eines Korkens hat.

Bruce Banner is a pretty normal looking human, right? But then he turns into The Hulk (I guess The is his first name since it is always capitalized). So, if he goes from 70 kilograms as a human to almost 300 kg as The Hulk, where does the extra mass come from? What if this is conversion of energy to mass from Einstein’s E = mc2? This would take 2.7 x 1019 Joules of energy. Where does that come from? The total power output from the Sun is about 4 x 1026 Watts. However, only about 1.7 x 1017 Watts hits the Earth. If The Hulk used ALL of this solar energy, it would take over 2 and a half minutes in order to capture enough energy to “transform”. I guess this could be the “getting angry time”.

But what if The Hulk doesn’t change mass? In this case, he would still be 70 kg, but have a different density. Solving for the density, I get [some formula].

Using the same values for heights, this would put The Hulk’s density at 0.24 times the density of a human. If I assume about 1000 kg/m3 for a human, the Hulk would have a density of 240 kg/m3. Just to compare, this is similar to the density of cork.
