Alternate Realities
What will happen if somehow we manage to look into the future? As per the 'Observer effect' in Quantum Mechanics, observing a situation changes it, because an act of observation causes a disturbance in the observed system. It means that when we look at things, they behave differently than while we are not looking at them. But how do the system knows that it is being observed? We only see an object when light falls on it and as it reflects the light back to our eyes, that makes it visible to us. But in Quantum Physics, when light hits a particle, for example, an electron, it is deflected from its original path and behaves differently, which forms the basis of Observer effect. However this change is very small and negligible at subatomic levels, but when dealing with complex theories like time travel it can make a huge difference. So in a way, if we somehow manage to look into the future, the very action of looking into the future can change the future. Which is good in a way be...
