To celebrate the release of "Avengers: Endgame," Insider had physicist 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."
