I have learned about g = 9.81 m/s^2.

So to reach light speed, with a comfortable chair, with
my own weight, I need to acellerate 300,000,000 / 9.81 = 30581039.76 seconds.
This is 8494 hours, and that is 352 days, say 1 year if I take it easy.

And 1 g is not that much, does not take a string engine.


Oh, I forgot to tell you--when you get going fast like that, every micro
meteoroid and grain of dust will hit your ship like high speed cannon
balls... and you won't even see them coming! Nice suicide mission.

Yes Mr Sam, those meteoroids and dust particles could be dangerous.
I will have to make a thick shield for that, maybe some force field,
give these particles electric charge by ionisation and a strong magnetic
field to slow them down.
Thats is only an engineering problem.
But this extra power that is needed when close to light speed in that webpage
you show, is this because there is some substance, like water, in space?
I always thought that space, except for those dust particles was empty?
And that does not look like linear more power with speed, why is this
exactly at light speed so strong?

Is that an official theory? Then we could not go to those planets :-(
Most in this group say that relativity theory is wrong, now should I not
believe this, and then how can we ever save the human race?
