i was wondering about time travel and imagining that if i was to go back in time, lets say 1 minute, will i have to rewind the whole world or could i just rewind a specific place. i came to the conclusion that i dont need to rewind the whole world. if i just rewind the events that occured in a particular area, the whole world will not be effected by it. The whole world does not know about it. This led me to thinking that the whole world exists because many people are perceiving the same thing that it exists. What will happen if they did not perceive this world? Will the world still exist? Please share your ideas in less than 100 words. if its too lengthy, i skip it.
