Well, Rangsk. I would have to disagree with your assessment. Although you explained it quite well. So allow me to recap and you can tell me why I should have studied all this before I replied
As I understand your post, the reason why we can't travel at the speed of light, is because we could not (cannot) measure the distance we are traveling. Hence the closer we get to that point, the farther we are from it (
since the faster it gets, the slower time gets for it)
The reason why I disagree (if I understand the post correctly) the person inside the craft would not be able to tell if they had reached light speed because (to him) he is not going very fast at all. But to someone on the outside. They should be able to determine the proper speed. Because they would be able to tell the distance and the time it’s taking them to cover it.
Or is that to literal?
