Have you heard the phrase “You need to live in the present and not look back at the past”? Whoever says this simply does not know physics. Everything that you see around does not take place live and is more like watching a video while slowing down the Internet. So, for example, the sun's rays need 8 minutes and 20 seconds to reach the Earth. You see the Sun in the past, and if it disappears right now, you will know about it only after over eight minutes. And this applies to everything since you see the picture only when the photons of light reach your eyes. Looking at an object from a distance of one meter, you see it as it was 1/299792458 seconds ago. A tiny amount of time, but you are still looking into the past.
