Humans Will Never Leave the Solar System

The dream of traveling to other planets has always been brewing in the human mind, especially since we actually sent men to the moon 57 years ago. Now we are going back to the moon, and since we've managed to sent robots to Mars, we've been thinking about following them. It won't be easy, but the moon wasn't easy, either, until we did it. Why not dream even bigger, like visiting the exoplanets we've learned about? Kurzgesagt explains why that won't ever happen. 

First, there's the distance that's hard to wrap our heads around. The Voyager probes are only now reaching the edge of the solar system, and they've been flying for 49 years! Well, what is we learned to go faster? We could, but even so, there are so many other physics problems to solve that it probably won't happen. Galactic travel is not what you see in a Star Wars movie. On top of all the challenges, would such long distance travel ever be worth the money, sweat, and lives it would require?  This video has an ad from 4:06 to 5:18.
