Why the arrow of time?

Why is it that we cannot alter the past nor directly view the future?

Your post question is seemingly different to the topic title question, do you wish to know why an ''arrow'' of time or why we can not alter the past?


We can directly ''observe'' the future ''paths'' subjectively and alter the future ''paths''.  This allows the ability to ''predict'' things such as whether or not a meteor would strike the Earth, we could change the Meteors trajectory by applying external force ''changing'' the future.

It seems to me that the arrow of time is defined by how past and future relate informationally to the observer.  That is, the direction of time is from the state in which the observer can confirmedly know but not alter the situation, to the state in which the observer can alter but not confirmedly know the situation.  If that is not the definition, then what is?

You can't change what hasn't happened. You can form a different/alternate 'now'.
