Two million years in the case of the Andromeda, but the universe is about 13.7 billion years old, and they've caught some light from not that far off of then.
So much for the Biblically derived 4400 year old earth.

Yeah, I've no idea where they get those absurd contrived theories.
Of if you talk to a hardcore flat earther it was all designed by a very talented graphic design artist on the worlds largest IMAX theater screen.....(You may want to google exactly what you are talking about with light from stars and galaxies.... try tens to hundreds of thousands of years ago too, and we do understand these quantities. Planets are dark and you can't see them. Sorry don't mean to be a buzz kill but memes are better when they are accurate.)

um its more than decades or centurys past, its more like millions of years ago light traveling
DID YOU KNOW WHEN YOU SPOT A STAR IN THE NIGHT SKY THAT YOU ARE ACTUALLY VIEWING THE PAST? SINCE SOME STARS, PLANETS AND GALAXIES ARE LOCATED SO FAR AWAY, THE LIGHT WE SEE FROM THEM HERE ON EARTH MAY HAVE BEEN EMITTED YEARS, DECADES AND EVEN CENTURIES AGO. THEY TRAVELLED SO MUCH THAT WE DON'T UNDERSTAND THESE QUANTITIES. THEY TRAVELLED A LOT LIKE YOU. THINK ABOUT THAT WHEN YOU LOOK UP INTO THE PAST.
