Great vid and concept but... If you could build a space craft that could accelerating continuously at 1G it would takes about one year to get to 99% of the speed of light.
Of course the obvious problem is propulsion and fuel. How could you ever carry enough fuel or what could you use besides on board fuel?
Assuming you solved all of the problems then you have to slow down again so that would take another year at 1G.

If we could also invent "Inertia Dampers" we could accelerate and decelerate much faster than 1G. But the science also get's strange at close to the speed of light. (time and mass)

Honestly it's all too hard right now but in a thousand years who knows?

"Assuming that 1 g = 10 m/s^2 and that c = 300,000,000 m/s, we get:
v = a t
t = v / a
t = 300,000,000/10 = 30,000,000 seconds or 347.222 days."*
