Why does light from far away galaxies take longer to reach us than light from the sun?
Because we our only able to see something when the light from it hits our eyes, if there’s no light from or on the object then we would find it harder to see it… Now though the speed of light is very fast, it would still take a long time even from the closest star to our solar system and could take a million years to reach us, but when it does we can finally see it…However, the light from the stars would be the light that was sent out a million years ago so we are seeing what that star looked like a million years ago, we are literally looking into the past… (Most stars are so far away it takes a billion years for the light to reach us) Now the sun is much closer in distance and so the distance the light has to travel is much less (only a few million miles, small in comparison to the universe) and it takes the light from the sun 8 minutes to reach us, so we are seeing the sun but what it looked like 8 minutes ago… So, imagine if the sun went out tomorrow…it would take 8 minute
