The speed of light is often cited as the fastest anything can travel in our universe. While this might be true, the speed of light is the EFFECT and not the CAUSE of this phenomenon. So what's the cause? On this week's episode of Space Time, Matt helps explain what the speed of light REALLY is and why it’s the cosmic speed limit of our universe!
