Travelling Space: Near the Speed of Light
Imagine travelling the vastness of the universe at the speed of light—the ultimate speed limit as revealed by Einstein’s theory of relativity. Space travel at light speed will require huge funding and a spacecraft designed to keep up with the instantaneous and constant acceleration. Let’s say we have the spaceflight system with the speed of light. How long it would take us to travel to the moon, mars, the nearest star and beyond? Check the answers below.
