First I am not sure if this is the correct place to post this thread, but the thread will be about optics, quantum physics and special relativity, so it is a mixed subject.
Please watch this video first:
This technology allows capturing videos at mind blowing 1 trillion fps, which allows us to see how light propagates in slow motion!
It is a fascinating video, my mind was blown away when I watched it, and it left me puzzled over 2 things:
1- Laser beam captured frozen in space:
If you watch the video at 1:40 you can clearly see a photo for a bullet of light captured frozen in space. But according to special relativity we are not supposed to be able to see light (moving at c) frozen in all cases, what am I missing here?!
2- Order of events:
At 9:24 it seems the order of events is reversed! the presenter said:

Can someone explain what is going on here? Is causality reversed here?!"it turns out, because we are recording nearly at speed of light, we have strange effects, and Einstein would have loved to see this picture. The order at which events take place in this world appear in the camera with sometimes revered order"
Thanks,
