So whether you are looking at the light from the photo above or the reflected light from the moon below
it always travels at the same speed.

Chapter 3 Part 2
Despite it being accepted that it is aether that light travels through, evidence to the contrary began to mount. The primary evidence that light doesn't need a medium through which to travel, is that experiments designed to measure the change in the speed of light depending on the motion of the observer failed to find any difference in the speed of light. Meaning that no matter what point of view you observe light from it is always traveling at the same speed. That speed being 3X10^8 meters per second. (Or 670 million miles an hour for those of you who don't use international units.)

Wow it is really interesting that if you look at light from the photo or the moon it always travels the same speed.
ReplyDeleteLight is confusing. The scientific community has been trying forever to uncover how it works and now I understand why. Generally it works against everything you know. How it is distributed, how it flys, etc. Keep up the good work.
