Scientists have created a camera that has the ability to take 1012 (That is 1 with 12 zeros) FPS. And with a short enough pulse from a laser, they have the ability to watch the small beam move through space.

This question presupposes that scientists should cultive these traits. It is a philosophical, and not a scientific question. "Open-mindedness" and "skepticism" are not defined, and both are highly subjective terms. What a scientist should do -- must do -- is be led wherever the verifiable hard evidence he is able to collect takes him. To do otherwise is to be doing something other than "science".
Such claims should be treated with great skepticism.
