• Absolutely. This is why I used the phrase "up to 4,000" and not "always 4,000". It's just the fact that we can see stars "up to" 4,000 light yearsï»¿ away with the naked eye, so we can see "up to" 4,000 years into the past. In fact, we can see the Andromeda Galaxy with the naked eye (if you are in a very rural area with no light pollution), and it is 2.5 MILLION light years away, but I thought I would limit my response to just the stars we can see.

• And weï»¿ haven't even started to talk about the observable universe ;)

• I love your videos Derek, but to first say some information is missleading then round the numbers of the distance to the moon and sun is somewhat wrong.

The distance from the Earth to the moon for light is 1,26 seconds (not 1) That might seam trivial, but it is a difference of 77946.04 Km. That is alot. And to the sun it is 8 minutes and 20 seconds (on average). That is a difference of 5,995,849.16 Km .... It makes a hugeï»¿ difference. Sorry to complain. Love your channel!

• Iï»¿ missed a "k" it is 290,792 km/s

• It is only coincidence. The moons orbital distance variesï»¿ between 356,700 km to 406,300 km depending on where in it's orbit it is. By mear coincidence, the distance to the moon (about 30 Earth diameters) is the exakt size ration as the sun based on it's distance from us. Remember it takes the light 1,26 seconds to reach the moon from us. To the sun it is 8 minutes and 20 seconds. That is almost 397 times the distance. And light travels 290.792 m/s (in Vacuum)

• Coincidence. I wouldn't say luck. We don't really benefit from the fact that the sun and moonï»¿ are the same relative size.

• me and my friends were arguing aboutï»¿ this but i was right SUCK IT GUYS!!! HAHA

• I got an amazing idea from these vids of yours: you should prank people scientifically and let us see the reactions. This vid already is kindaï»¿ close to that, tho only one reaction.

• I would have liked to see theï»¿ rest of the peoples reactions when you showed them how far it actually is.

• i would like toï»¿ know why the moon covers the sun so precisely during an eclipse, can't be just luck right?
