Joe, Nick, and Georgia dig into a discussion about the nature of speed, starting with the basics of how speed is measured and moving into the fantastical with speedsters from comics and movies like The Flash, Sonic the Hedgehog, and Quicksilver. They explore the scientific concepts behind the speed of sound and light, touching on historical attempts to measure these velocities. The conversation also includes playful banter about fictional portrayals of speed, such as those in the Sonic movies and Superman, while considering the biological and physical implications of moving at extreme speeds.

Show Notes & References

Speed Measurement: Distance traveled per unit of time (e.g., mph, km/h, m/s).

Speed of Sound: ~767 mph (1,235 km/h, Mach 1) in air at sea level.

Speed of Light: 299,792 km/s (~186,282 miles/s), fastest possible speed in the universe.

Mach Number: Speed relative to sound (e.g., Mach 2 = twice the speed of sound).

Speedsters in Fiction & Reality

FASTEST REAL-LIFE CREATURES:

Peregrine Falcon (dive speed of ~240 mph)

Cheetah (~75 mph sprint)

Usain Bolt (~28 mph top sprint speed)

FICTIONAL SPEEDSTERS MENTIONED:

Sonic the Hedgehog (~Mach 1 in games, faster in comics/movies)

The Flash (faster-than-light with Speed Force mechanics)

Quicksilver (Marvel; superhuman, but slower than Flash)

Superman (variable speeds, sometimes FTL in comics)

Roadrunner & Speedy Gonzales (cartoon physics apply!)

The Science of Extreme Speed

Friction & Heat: Moving too fast generates heat, which could burn a speedster without protective gear.

Energy Needs: High-speed movement requires enormous caloric intake (e.g., The Flash’s obsession with food).

Reaction Time & Perception: The human brain processes around 60-75 fps, but speedsters would need far beyond that to react properly.

G-Forces & Acceleration: Sudden starts and stops would cause internal damage unless counteracted.

Breathing would be difficult when running at super fast speeds.

Energy Cost of Speedsters (Estimated in Big Macs):

Human Sprint (~10 m/s) = ~0.09 Big Macs

Subsonic Speed (~100 m/s) = ~1.8 Big Macs

Supersonic Speed (~500 m/s) = ~18 Big Macs

Near-Light Speed (~0.1c) = ~1,818 Big Macs

We want to Hear From You (leave a comment):

If you could have super speed for a day, what would be the first thing you’d do?

If Sonic the Hedgehog and The Flash raced around the Earth, who would win—and how would they deal with things like ocean crossings and mountains?

What’s the weirdest or most creative way you could “break” the laws of physics to achieve faster-than-light travel in real life?
