Скачать или смотреть We Can Travel at Light Speed... And It Still Won't Be Fast Enough

What if humanity could travel at the speed of light tomorrow? 186,000 miles per second. The fastest anything can move in our universe. You'd reach the Moon in 1.3 seconds. Mars in 3 minutes. You could cross the entire solar system before dinner.

But point that ship toward the nearest star, and the cracks begin to show. Proxima Centauri takes over 4 years. Betelgeuse takes over 500 years. The center of our own galaxy takes 26,000 years. And that's just one galaxy among two trillion.

This calming long-form space documentary explores what happens when you test the universe's absolute speed limit against the actual scale of the cosmos - from nearby stars to distant galaxies to the expanding edge of everything. The answer isn't what most people expect. Even at perfect light speed, 94% of the observable universe is already permanently out of reach. And that percentage is growing.
