- Is spacetime discrete or continuous? 7 answers
I do not know how to use professional words to ask my question, so I will try to use a layman language. Please bear with me for a moment.
A ROUGH GUESS
The world our eyes are seeing every moment is a picture reflected in our eyes. I guess our eyes are like cameras, that are taking pictures "continually". I suppose there is a frequency in this picture taking. Say it is 1/10000s, the time it takes a picture, let's assume it is negligible. Something like that.
My question is, if we take a picture at 0/10000s, 1/10000s, 2/10000s, etc. How do I know that between the time 1/10000s and 2/10000s, the world exists?
- If my guess is wrong, then what is the real picture? What is happening in reality?
- If my guess is correct, how do we know the world exists continually? How would you use experimental methods to prove it? Or there might be theoretically, many worlds in our time gaps coexisting with ours?
I feel I still have not got a satisfied answer for my first question. Could anyone explain to me: is our vision equipment (i.e., our eyes) functioning continually or discretely?
