In one of the most famous comic book panels of all time,Â Gwen Stacy loses her life to the oppressive pull of gravity. Attempting to save her with a lifeline of web after she fell from top of a city bridge,Â Spider-Man loses the love of his life does catch her, but the sudden deceleration snaps her neck. But we've gone back and evaluated this scene like science-whiz Peter Parker would, and now we wonder: would Stacy really have become one of the most infamous comic deaths?In my latest episode of Because Science, we are recreating the circumstances on Gwenâ€™s grand goodnight, except this time we will be evaluating it using math, science, and engineering. If Spider-Man were using a material like real spider silk in his web shooters (why wouldnâ€™t he be?), would there really be a sudden, neck-snapping deceleration? We know enough about the material that we can calculate stretch, strength, and g-forces.
