Physicist Breaks Down The Science Of 10 Iconic Marvel Scenes | How Real Is It?

To celebrate the release of “Avengers: Endgame,” we had physicist (and lifelong comic book fan) Jim Kakalios take a closer look at the physics of the Marvel universe. Here he reacts to 10 memorable scenes from Marvel movies and rates them based on their accuracy. Find out what exactly quantum mechanics, time dilation, Einstein’s theory of special relativity, and spider silk tell us about the superheroes of the Marvel franchise.

Which weapon would you rather have in a fight: Thor’s Mjolnir hammer or Captain America’s shield? Hint: The answer has to do with the conservation of energy - and the sonoluminescence of vibranium. Dr. Kakalios breaks down the physics behind this and many other Marvel phenomena, including Shuri’s holographic car in “Black Panther;” Peter Parker’s spider-webbing train save in “Spider-Man 2;” the multiverse theory of “Doctor Strange;” the role of Pym particles and the Higgs boson in “Ant-Man;” artificial gravity in “Guardians of the Galaxy;” and Tony Stark’s cybernetic helmet and gold-titanium exoskeleton in “Iron Man.” He sheds light on why Carol Danvers doesn’t age from “Captain Marvel” to “Avengers: Endgame;” why the Space Stone is so powerful when yielded by Thanos in “Avengers: Infinity War;” and what’s with all the talk of quantum entanglement, quantum tunneling, and “quantum mumbo-jumbo” in “Ant-Man and the Wasp.”

Kakalios is the author of three books - “The Physics of Superheroes,” “The Physics of Everyday Things,” and “The Amazing Story of Quantum Mechanics.” He was a science consultant for Sony’s 2012 film “The Amazing Spider-Man.” Before that, he won an Emmy for his work as a science consultant for the Warner Bros. superhero film “Watchmen.” A physics professor at the University of Minnesota, Kakalios teaches a popular class that uses comic books to illustrate the principles of physics.

    Sorry, this guy failed the very first clip about gravity. Unless you are standing with legs completely locked, the muscles in your legs are under tension to counteract the effects of gravity. If you suddenly became weightless, that tension would exceed the force acting against it, propelling your now weightless body into the air.
