What is Time?
Time can be best imagined by looking at water. When you drop a stone into a still pond you create ripples. Our shared experience of time is but a ride on a single ripple.
Which time ripple are we on? Are there other ripples ahead of us? Behind us? Yes, I imagine so. Just as in the pond analogy, there are surely other ripples of time. Not of our time. Which ripple we are riding on, I cannot say. All the ripples of time make up our universe.
If a ripple of time is impeded by a sufficiently large mass in space, we observe this as a black hole.
Why do I believe this is how time works?
Look around. You see time functioning this way in the galaxies, in storms, even when you drain the water in your sink.
Shouldn't time function in a way similar to sound and light? I think it does.
I want you to remember that every action you take is recorded in time. Every kindness. Every act of selfishness. Someone is always watching. It is Time. When you are done with this time, you will realize how much your time mattered - or didn't. Make your time matter. Be kind to others. Get to know them. Help them. Struggle through the hard times, and cherish the good.
