It's never said that the first spaceship travels at light speed.

>>8732756
sorry... first ship travels at half the speed of light. I really should have mentioned that in the op >>8732745


also this is the question explained in the video

>>8732745
>A spaceship leaves earth now for a planet around another star 200 light years away. In 100 years you leave earth in a spaceship that can go 2c, twice the speed of light headed for the same planet.
not possible, if you travelled faster than light you would be going back in time

he'd see fuck all until after we passed and then heavily redshifted light for a bit

>>8732745
>2c
a fastly approaching shitpost

Did you watch the video? That's the entire point of the exercise, to demonstrate how going faster than light necessarily means traveling backwards in time

>neccesserily means

No it does not. I love how people of science are first to say smth isnt possible, and yet decase after decade they are the ones proved to bw wrong every time.

When will we realize we are ants?
Give it time. Our knowledge of the univ is not complete and until it is there can always Always be a catch 22.

Prove you aren't a brainlet by answering the following question.
A spaceship with top speed of 1c leaves earth now for a planet around another star 200 light years away. In 100 years a spaceship that can go 2c leaves earth, 50 years later space ship that can go 4c leaves earth, 25 years later space ship that can go 8c leaves earth, 12.5 years later space ship that can go 16c leaves earth, 6.25 years later space ship that can go 32c leaves earth, 3.125 years later space ship that can go 64c leaves earth, 1.5625 years later space ship that can go 128c leaves earth, 0.78125 years later space ship that can go 256c leaves earth, 0.390625 years later space ship that can go 512c leaves earth, 0.1953125 years later space ship that can go 1024c leaves earth, 0.09765625 years later space ship that can go 2048c leaves earth at two thousand forty eight times the speed of light headed for the same planet.
what would the captain of the second slowest ship see as he watches 12th ship overtake 4th ship while going backwards in time himself?
assume that faster than light travel will be possible in 100 years.

can no one answer this? I don't even know how to think about what someone passing me moving forward in space but backward in time would look like.

How could anyone answer this? The question is retarded and we have no basis to even hypothesize how an impossible event would look like. These fucking garbage threads pop up every single time PBS releases a new video.
