Hi, i'm a new member who has just embarked on my journey into Quantum Mechanics and String Theory. I was a grade A student in contemporary high school physics, however i am aware that i have a lot to catch up on (i assure you the text books are on order), so please don't attack me if the answer to my question is simple. The current thought to the best of my knowledge is that we are 3ed dimensional beings, moving along in the 4th dimension of time. Our movement is linear from our creation to our death, however at any moment we exist only as a point on this line. My understanding is that a point takes up no space on the line and that 2 points on a line have infinite points between them. therefore it is imposible to traverse every point on our timeline. From here i thought that perhaps we merely jump from point to point on our timeline, existing within a finite number of points. A finite number of points which in themselves take up no length of time, results in our entirety of existance to, well simply not exist. Has string theory or any other theory redescribed time to solve this dillema?
