What did Eadweard Muybridge demonstrate through photography in 1878?

• A. A horse lifts all four feet off the ground at times
• B. The earth revolves around the sun
• C. The horse can fly
• D. The camera can capture sound

Answer: (A)

Think about how motion can be revealed by a sequence of images rather than a single snapshot. Muybridge arranged several cameras along a track and triggered them in order as a horse ran. The resulting series shows each moment of the gallop, making visible a moment when all four hooves are off the ground. This provided concrete evidence that a horse does lift all four feet at certain points during fast locomotion, addressing a long-standing question about animal movement. The other ideas aren’t what this demonstration was about: it doesn’t prove the Earth moves around the Sun, it isn’t about a horse flying, and early photography didn’t capture sound.
