Space, the final frontier, they say. For all we know (barring all those governmental conspiracies) there had not been anyway for humans to go that far but there had always been theories. Some of these theories are starting to materialise and look promising:
1. Photonic Propulsion
With a large, reflective sail, it would be "possible to generate enough momentum to accelerate a spacecraft" via lasers pulsing light from the surface of the Earth.Just 3 days to Mars and another 3 days back. Wow.
2. Antimatter Rockets
Another cool theory would be using antimatter rockets with energy created when positrons and electrons come into contact to power spacecrafts. Speed can go up to 72 million miles per hour.
