PS - change is not a basic physics concept. Change is how humans think of movement. The more fundamental of the two is movement. More fundamental than movement is space and time.

Time, Distance, and Mass are the fundamental units of physics.
I think I did. But did you understand my question was "How can you Know"?

Ok, let me try to explain what I and some others are saying.

Lets take Plato's definition of Knowledge as Justified, True, Belief.

Epistemology - Wikipedia, the free encyclopedia

You've got the Belief part, and you've given excellent Justification. All that now stands in the way of an assertion that time has objective reality is the True part.

And this is where we run into a problem, because whatever time is, we can't observe it under a microscope. And the excerpt I posted from the Stanford Philosophy of Science site says knowledge of unobserved phenomenon is impossible.

How can we get around this? How can we Know time has objective reality?

EDIT:

Or did I misconstrue/misunderstand what you were saying?

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
