I watched a video which basically stated that if the universe was infinite then it would begin repeating itself because there is a finite amount of ways to arrange even an infinite number of atoms. So, you could reach a point in space that is 100% identical to where we are now and it would be impossible to tell the difference other than the fact you know you’ve travelled away from the original point. But then, you could make the assumption that you’ve looped back and it would be equally valid.
