At 1:58, the moving clock is slower so 2L/C X gamma supposed to be the equation, shouldn't it? So, why we multiplied with gamma instead of division, and why C^2? "Feel free to correct me" may someone suggest to me how? LOL. You are hilarious professor.

I love this course and I understand it, and see the logic, nonetheless I find it fascinating that if another ship travelling in the opposite direction at much slower speed, they will of course say the distance and travel time is different than their space-travelling counterparts, even when crossing one another in a very close fly-by. This seems to imply that space can be severely ‘distorted’, for the lack of a better word, in one very local space, dependent upon the traveller’s speed/perspective, which says something very interesting about space existing in multiple configurations simultaneously. I guess it is not distortion, but more perspective being in the eye of the beholder. Incredible.

Argh, I actually meant to post this in the previous section. Sorry!

It's already corrected at7.02.

At 1:58, the moving clock is slower so (2L/C) needs to be multiplied by gamma so that time is longer. Dividing by gamma would make the moving clock tick at a faster rate. Gamma is always greater than 1.
