  2. Your post, included comments, or your title/comment should include some kind of commentary or remark on the subject of the screen capture. Your title must include at least one word relevant to your post.
  3. You are encouraged to provide a link back to the source of your screen capture in the body of your post.
  4. Current politics and news are allowed, but discouraged. There MUST be some kind of human commentary/reaction included (either by the original poster or you). Just news articles or headlines will be deleted.
  5. Doctored posts/images and AI are allowed, but discouraged. You MUST indicate this in your post (even if you didn't originally know). If an image is found to be fabricated or edited in any way and it is not properly labeled, it will be deleted.

a second is defined as the time it takes for a caesium atom to oscillate exactly 9192631770 times, at least according to the SI. a meter is then defined, as you said, as the distance light travels in 1/299792458 seconds, which corresponds to some large number of oscillations of those caesium atoms. these numbers are pretty much arbitrary though, we just picked them to match our previous, less precise, definitions of meters and seconds. but using oscillations of caesium atoms and speeds of light in your is completely equivalent to using meters and seconds, except that the latter units are more familiar to us
