I don't know pretty much about physics and I'm sorry if there is something I should know that simply makes it clear this couldn't happen.
But I asked this myself now already several times and decided to post it here:
If I'm remembering right from my high school times, light is moving with a constant speed but is affected by obstacles so I assume it could be possible that the light emitted by an object may be slowed on its way to my eye.
So given that to this object something happens that makes it looking quite different and the light before and after the change of appearance is now on the way to my eye and on the way any kind of event (like "a wild vacuum appears"...) occurs that makes the light waves which are behind speed up a bit so that they both arrive and get noticed (absorbed or what ever it would be called) by my eye at the same time, what would it look like?
Would I see the object as something like it never actually looked like and I would notice the mixture of the both objects colours?
What if it also changed its shape and form? Would I just see both objects together or would some blur-like effect appear?
