Time Dilation and Gravitational Waves

The video explores the concept of time dilation, explaining how time ticks faster at different heights and speeds. It discusses the effects of speed on time perception, using examples like sprinters and high-speed trains. The International Space Station is highlighted for its unique time dilation effects due to its speed and altitude. The video also delves into the nature of light as a constant, discovered through electromagnetism, and introduces gravitational waves, explaining their impact on space and time.
