The past, history, and heritage

These are three different things. Allow me to explain.

The past is what happened before right now. For example, I walked my dog about an hour ago, I made coffee about 45 minutes ago and finished that coffee about 30 minutes ago. 951 years ago, Normans invaded England. That's the past -- what happened. We in 2017 cannot go back to the past and see how it unfolded, so we need....

History is an explanation and interpretation of why and how events occurred in the past, and these interpretations are based on primary source documentation. Since very few people agree with everything 100% of the time, history is usually written (or covered in documentary film), and revised over and over again. If history were not revisionist, then there'd be only one interpretation of every past human event.

Heritage is a belief system about the way people wanted the past to have existed and transpired, and this usually serves religious and political purposes of the present-day.

The future is an indeterminate cone in the vector of time that has its origin in the present.

The plan is a construct of human intention to delineate a path through the "cone".

The legacy is the objective means by which the path is materialized.

And now for a word from one of our sponsors.

Isn't that a Newtonian model?

Sub atomic particles don't behave as shown in your diagram, which once discovered in the early 1900's began the unraveling of Newton's theory as the final word on the subject.

Neither is time a constant in the universe. Einsteins model describes time-space as occurring all at once everywhere



The plan you mention already succeeded or failed and has yet to be decided upon.

My ducks just say quack.

No, it's a 4-vector relativistic one, generally referred to as the Minkowski diagram, IIRC.

It comes out of the Special Theory of Relativity.

But please, continue...

The momentarily co-moving inertial frames along the world line of a rapidly accelerating observer (center). The vertical direction indicates time, while the horizontal indicates distance, the dashed line is the spacetime trajectory ("world line") of the observer. The small dots are specific events in spacetime. If one imagines these events to be the flashing of a light, then the events that pass the two diagonal lines in the bottom half of the image (the past light cone of the observer in the origin) are the events visible to the observer. The slope of the world line (deviation from being vertical) gives the relative velocity to the observer. Note how the momentarily co-moving inertial frame changes when the observer accelerates.

I think we've been here before.
