My post of August 28, 2015, asked a series of questions about those ripples in a garden pool that many of us enjoy creating at one time or another. The ripples travel the length of the pool and return, over and over—for how long? If no one else makes waves in the pool, would our ripples continue traveling back and forth from one end of the pool to the other forever?
The intuitive answer, I believe, is "yes". In the absence of some opposing equal or greater force, the ripples will continue to diminish forever, never reaching, but always approaching, the zero point. That intuitive answer, I believe, is correct, but the logic for the answer is faulty because it fails to take into account an important point—we live in a quantum world. Let me explain.
It is important to establish first that the waves are waves of energy, not waves of water—no water travels the length of the pool—only the energy provided by your initial push travels the length of the pool and returns. (To see this for yourself, drop a cork in the water prior to starting the ripples—the cork will remain at the end of the pool where you dropped it.)
This is important because we live in a quantum world and one of the most important features of a quantum world is that energy is made of fundamental units, indivisible packets, rather than being divisible to a vanishing point. As the successive waves lose more and more of their energy, they eventually will reach that minimum size necessary for energy to exist in our time-and-space world and at that point will simply disappear. Are they gone forever?
It is well-established that at the quantum level time does not pass but is. Just as in our three-dimensional world you do not say that space passes, it simply is, in the many-dimensional quantum world time (one of the many dimensions) does not pass but is.[1] Those ripples will be there forever, tucked away in their own segment of time. But I must attach a proviso to this answer.
The proviso: The ripples will be there as long as our time-space world continues to exist. Is that forever? I will answer that question pragmatically: It is forever in every sense that matters to us as creatures of time and space.
That established, does it matter that the ripples will be there forever? Very much so since, by extension, we can say that all those "ripples" created by things we share our world with—now, in the future, and in the past—will continue to exist forever. Our ancestors and descendants and the "ripples" they create, will continue to exist "forever".
I would very much enjoy discussing this "forever" question with you. Please comment.
