Yes. You go outside and touch grass.
very philosophical question mens
Thinking of something? maybe? probably not tho
depends on how you view "change". If you hold your breath for five seconds instead of breathing, the amount of o2/co2 is different from what it would be if you breathed normally. but nothing of significance has changed, this minuscule difference of o2/co2 does not matter. so if you mean nothing at all changes, i don't think so. but many things that you do or do not do are of little/no consequence
What is a "change"? Bc many actions, like waving your hand in an empty room, would theoretically go entirely unnoticed by anyone else, but you expelled energy, you moved air molecules with the movement, you burned calories, even if the amount in the long run is practically nothing, it still isn't nothing.
it has already been proven that universal isn't local
so any action that happens in the universe, it probably has an affect on some other particle in some other corner of the universe in real time
yes this thread is proof of it
I don’t know, but it’s a good question.
How would you measure the non-impact your action would have on the outside world?
