Whale Calls Debunk a Physics Paradox: It’s All About Wave Interference

An oceanographer noticed humpback calls near Massachusetts appeared to exceed the speed of sound, but the effect isn’t physics breaking — it comes from interference between the direct sound and its surface-reflected echo reaching the hydrophone, making the strongest signal peak appear to arrive faster. This observer-relative illusion aligns with special relativity concepts, and the researchers propose experiments to verify this underwater SR-like phenomenon, with potential applications to light-based tests.
