This is my first topic and I do not have a physical education degree. How can I put this...I´m only a curious guy who loves physics and mechanics! So, what brings me here... Travelling at the speed of light (SOL) is only possible in our most inspired dreams and sci-fi movies but let´s pretend we can do it. Imagine a space-ship capable of reaching SOL. What about us? We are the crew. Can we survive the rush of acceleration?! In order to let us survive the acceleration, it would be necessary to bring it to a rising-speed (or G-force) that we can outlive. 7 G´s is quite confortable. So...here is where I need your help. How much time do we need to reach SOL, accelerating at 7 G´s?! And how far are we from the starting point when we reach SOL?
