Have you ever had a feeling that we are living in the past than present. Is present really an instant occurrence or the we just living in a delusion that everything we sense is in present.
Let’s bind our vision in Cosmic scale and consider things for a moment . In universe, everything travels at some rate and which is approximately measurable. The fastest moving particle is the photon which represents a quantum of light. Light travels at 300,000km/s and in the same way sound travels certain speeds depending upon the temperature. When we gaze into the dark sky, we observe little dots called stars glittering in the vast cosmic arena. These stars are mindbogglingly away from us, like billions of light years away. Those tiny dots that appear in the sky, are the past images of that star. The light emitted by the star has to travel, those billion light year to reach us. The nearest star to the Earth, apart from our very own sun is Proxima Centauri, which is a part of Alpha Centauri tri-star system is around 4.36 million light years away from us. When we observe the star, we are actually looking into its past.
When we scale that down to the human level, the Sun and the moon, the light takes around approx., 8 minutes for the former and approx., 2sec for the latter to reach us. Even this article you’re reading, the light takes around 2nano seconds to reach your eye if the distance between you and the screen is 2 feet. We may not have witnessed Dinosaurs legacy, but the light of then dinosaurs era is still travelling in this vast space. If you build a telescope as big as earth and place at some million light years away from us, then you might have to chance to look back into the past.
As the process have been continuous and minute in human scale, we couldn’t observe the difference in our day to day life and spend our lives ignoring the details.
Past, Present and Future are the slabs of time-frames which we created, maybe we should bring it down to two.!
