According to science, the fastest speed possible for anything is the speed of light. the speed of light is about 186,000 miles per second. that means that in one minute, light travels 11,160,000 miles. the star nearest earth is the sun. it's about 93,000,000 miles from earth. therefore, it takes sunlight about eight minutes to travel to earth. so, when you see the sun, you aren't seeing it as it is. you're seeing it as it was eight minutes ago. since the stars are much farther away than our

Yes, yes, go on !  The nearest star to us that's outside of our solar system
is 4.2 light years away.  So when we see that star, we're not seeing it as
it is, we're seeing it as it was 4.2 years ago.  And all of the other stars
are much farther away from us than that one is.  We have detected
galaxies that we're not seeing as they are now, we're seeing them as
they were 13 billion years ago !

The moon is about 240,000 miles away from us.  When we look at the
moon, we're not seeing it as it is, we're seeing it as it was 1.3 seconds ago.

The refrigerator in your kitchen is about 12 feet from you.  So when you
look at the refrigerator, you're not seeing it as it is.  You're seeing it as it
was 0.0000000122 second ago.

It takes TIME for light to travel from one place to another.
