Since

Since everything in the universe is in motion, all matter, every atom, every sub-atomic partical, then all observation is by necessity of the past. We're always seeing what was, just a nanosecond, year, or light year ago. 

The background radiation glow from the Big Bang--13.8 billion years ago--the universe's most recent re-birth, is observable.

The moon is really the moon a second ago. The sun, nine minutes ago, a faraway galaxy, we see how it looked before its light traveled for trillions of miles to our telescope lens. We can essentially see only the past, therefore we may never witness anything 'just as it is

What else lingers in experience like this? What other observations that travel the deceptive distances of perception. Delayed, yet perfectly on time, defying the physical laws of memory and imagination? How does love travel thru the cosmos? Is it an undiscovered constant, like the precisely consistent and well-proven standard of light's finite speed? Do we feel the memory of a first kiss, first romance, as if it's today, or is memory the same unknown stuff scientists have only reluctantly named dark matter?

Can we feel love as it is today, and loved ones as they are from day-to-day? Or, is love too illusive to remain anywhere forever, everything in motion, every atom, all seen from the past?
