Introducing the perfect conversation starter for your next physics conference. One character drops the factoid "Light has no mass" while another counters with "Then how does gravity bend it?" causing visible confusion.
The beauty here is that both statements are technically correct. Light indeed has no rest mass, but according to Einstein's general relativity, gravity doesn't actually "pull" on mass—it warps spacetime itself. Light follows these curved paths not because it's heavy, but because it's traversing a universe that's been bent like a cosmic waterbed.
Nothing quite like watching cartoon characters inadvertently debate century-old physics problems that still confuse graduate students today.
