The distinction between past, present and
future is only an illusion, however persistent.
Modern physics tells us that time does not “move” forward. Instead, time, like space, simply is. To us humans who cannot help but perceive our lives as proceeding from yesterday to today to tomorrow, this is a mind-boggling concept. So let’s try to wrap some more words around it….
The laws of physics do not, indeed cannot, distinguish between an event in the “past” or an event in the “future.” In fact, these laws do not even distinguish between change which occurs “forward” in time or “backward” in time. The arrow of time exists only in our heads.
We humans insist that the past is gone, that only those things that can be perceived right now actually exist. Physics tells us, quite clearly, that though this is our perception, it is not reality. The reality is that everything, whether in the past, present or future, simply exists. Always. This is not wishful thinking. This is what hard science tells us is true, even if this truth, like other hard truths from science, seems patently absurd to our perceptions (like the fact that every atom making up all physical objects is mostly empty space, even though we perceive things as solid.)
Why am I harping on this this morning? Because this seemingly absurd description of reality comforts me. Because it means that nothing is ever lost, nothing ever dies. It means that we are still sitting at the dinner table in the old house on Wedgemere, even though you are long gone and the house has been sold away. It means that your infectious laugh is still ringing, even if my ears can no longer hear it.
