[00:00:00]What if we could reach another star within [music] your lifetime? Right now, the fastest spacecraft humanity has ever built would need around 20,000 [music] years to reach Alpha Centauri, the nearest star system. But scientists have a crazy new idea. Instead of using fuel, they want to push a tiny [music] spacecraft with pure light. A giant laser array on Earth would fire trillions of photons at an ultra-thin light sail. That push could accelerate the spacecraft [music] to 20% of the speed of light. The result? A journey that would normally take 20,000 years could take just 20 years. Even crazier, the same technology [music] could get us to Mars in only 32 hours. For the first time in history, interstellar travel might actually become possible.
