In order to undertake interstellar travel, we would need spacecraft with speeds near .

To make interstellar spaceflight more reasonable, a probe has to go really fast. On the order of at least one-tenth the speed of light. At that speed, spacecraft could reach Proxima Centauri in a handful of decades, and send back pictures a few years later, well within a human lifetime

Hydrogen is the most abundant element on the periodic table..hope it .
