Reply #154: The human body can't go much farther than we already have [View All]

unless we design engines that take us close to the speed of light and we discover worm holes.

The closest star to us is 4.2 light years away. It would take 4.2 years one-way IF we could go at the speed of light, which is a logical impossibility. The closest we could get is a 9 year long human-staffed trip in a ship that would have to go near the speed of light.

Human flight could maybe get to Mars. That's about it.

Robotic space exploration is great, and we should keep that up. But until we have engines that can go at 164,999.9 miles per hour, "man" ain't going nowhere.
