It is a natural phenomena: the older we get, the faster time subjectively goes for us. I remember when I was a kid an hour seemed like a long time. Now whole weeks can go by in the blink of an eye.
Time is also relative depending of the frame of reference. A beam of light emitted from a star 13 billion years ago traveling 13 billion lightyears experiences no passage of time or space between emission and absorption. 13 billion years is not even a moment for something traveling at the speed of light.
Nobody has really been able to effectively answer the question: what is time?
It seems beyond human understanding.
Learning to mindfully dwell in awareness of the present moment, rather than the past, or the future, is a challenge, but on the occasion I’m able to helps eliminate stress and anxiety.
“The present moment is the only moment available to us and it is the door to all other moments.”
