When you look at the moon, the image that man sees is a picture of his light coming out seconds and a third ago.
And when you actually look at the Sun, you see the Sun's past 8 minutes and 20 seconds ago, which is how long it takes light to travel from the Sun to your eyes!
And when you look at the Andromeda galaxy, you look at its ancient past 2.5 million years ago.
When you see the stars at night, you think a little!
You don't see the star's current location, but the light that reached you after you took the distance!
If we talk about a star 5000 light years away from Earth, if you look at it, you see the star's past 5000 years ago. And you won't see her present or her current location. !
When the death of a star, the birth of a star, or the occurrence of the supernova, is detected, it is true that what was discovered today happened in a time equal to its distance from Earth, if it is 2,000 years away, it means that it was 2,000 years ago and not now!
The rays from all the stars you see at night are years, hundreds or thousands of years before they start, so the stars you look at now may have disappeared, died, turned into another body, changed their real position!
In short, once you raise your eyes to the sky at night, you see the past...!
