How to travel faster than the speed of light, but never go faster than the speed of light!

Here is a video on how to calculate, how much faster than the speed of light,
we can travel "in mathematics", because of the time dilation.
Nothing can travel faster than the speed of light.
But......
We can do a calculation on how much faster "we think" we traveled,
because the time slowed down.
Here is the page to get some numbers on the time dilation.

If you think this is to complicated, you can do this also by just take the time on earth divided by the time on spacecraft and also get how much faster than light, we on the rocket, think we traveled.
My numbers are
101.92 / 9.02 = 11.299
This are all approximations.

One way to accelerate spaceships to high speeds would be to build large reflectors around our sun that then focus the sunlight to the sunsail on the spaceship.

Why not build a dysonsphere and make half of it as a reflector to accelerate spaceships to high speeds :)
