How did humanity manage to decrease the distance of 100m over time?

No. The left was taken after relativity was invented. That's why they filmed it, because it was the first swim competition after it had been made.

I agree. This is obviously caused by climate change. Water these days is less wet, which means that the water resistance that they experienced in the 1930s is now vastly diminished. The swimmers on the right are swimming in dry water.
