Here’s a thought, and you may need to take something fairly potent to visualize it: If we measure movement within a space by distance (here to there) and time (6 seconds to get there) or a combination of both (0 – 60 in 6 seconds), what other means of seeing movement do we have available?
Is the space between objects nothing, or is it a living, moving thing? It’s transparent, but we need it or we’d all be crammed together along with trees and buildings and each other. It’s also used to carry elements we need to survive, like oxygen and water, but what does it do and how does it move to accomodate the objects moving within it?
What if we were able to see the effect of the cause in every nanosecond as it happens? We see objects within space, such as a man standing right there. He takes a few steps in a straight line, perpendicular to our line of sight, and stops 3 feet to the left of where he was standing before. Visually, he has moved from one spot to another, and we witnessed the change in the “picture.” But that’s because he’s moving in transparent space.
What if it were colored blue? Or red? The space must move to replace where he has been—would it show up visually? Think of a cup of water drawn from a bucket. Does space rush to fill in the absence of an object, or is it stationary, and changes in form to take on the elements of the object as it passes?
In a time sequence, would we see the space as slowly filling in as he moves? How about the slow growth pattern of a tree?
So, a cardinal did not just fly across my yard from tree to bush this morning. In thousands of instants, he displaced areas of space in his flight.
I’m sure this is all answered by the discipline of Physics, but it’s kinda neat to come at it from an uneducated, visual and wondering kind of way.
Told you you might need something stronger than coffee to visualize my thoughts today.
