Traveling Waves: Crash Course Physics #17

Here we have an ordinary piece of rope. It’s not one of those magician’s ropes that can mysteriously put itself back together once it’s been cut it in half. And it’s not particularly strong or durable. But you might say that it does have special powers, because it’ll demonstrate for us the physics of traveling […]

Is Interstellar Travel Possible? (Time Dilation & The Speed of Light)

Is Interstellar Travel Possible? (Time Dilation & The Speed of Light)

How will humans colonize the stars beyond our own solar system? Research in space travel has only recently begun to tackle this problem. But almost 100 years ago, Albert Einstein made some revolutionary claims about the types of challenges that await those who travel at high speeds across the cosmos. Particularly with regards to the […]

Cherenkov Radiation: What If Something Travels Faster Than The Speed Of Light?

Have you ever noticed that when a supersonic military aircraft passes overhead at a very high speed, it leaves a thunderous boom in its wake? That tremendous cracking sound actually has a formal name – a SONIC BOOM. This intense phenomenon occurs when an object – in this case, an aircraft – travels faster than […]
