You’ve got questions. Eric has answers.

You asked us a lot of questions and now I'm going to try to answer as many as I possibly can in 45 seconds, so ready the timer, please, let's do this.
 
Dogs are not colorblind, although we've sometimes been told they are, and it takes 8 minutes, 20 seconds for light to travel to Earth from the Sun, which is well, lightning fast!  A New Orleans dentist, Levi Spear Parmly, invented dental floss back in 1815, although I know many of you aren't crazy about that string.  
 
As for whether we could be alone in the universe, this is a question that can't be answered today, and as for robot butlers, the day is coming soon when you could have one.  In addition, the tallest person ever known was Robert Wadlow, who in 1940, measured 8 feet 11.1 inches.  And, 12 people have walked on the moon.
 
On the question of how did life begin, I will pass, and I'm also going to pass on what makes us human, but here comes some more answers: A coin that falls from the Empire State Building could not kill you; it's pretty much true that no two snowflakes are alike; the first woman to win a Nobel Prize was Marie Curie, and she won two, in 1903 and 1911; my favorite science figure of all time is Carl Sagan.  And finally, I like long walks on the beach...Wait, what?
 
And that ends our lighting round, on a very weird note, but don't forget that you can see insightful videos by checking us out every day at Smithsonian.com.

    I honestly think that light takes so long to reach earth because we are so far away and there are so many planets between.

    Those were interesting facts, some of which I though to be true until I read this just now.

    According to the article,"You've got questions. Eric has answers," One reason it takes so long for the sun light to reach Earth is it takes 8 minutes, 20 seconds for light to travel to Earth from the Sun, which is well, lightning fast! Another reason is for whether we could be alone in the universe, this is a question that can't be answered today. Finally, is the sun is far away so it takes longer for the suns heat to reach Earth. That is why it take so long to reach the Earth.

    It takes a long time to reach Earth because it is the third planet from the sun(with two planets in the middle) and,the time the light travels.
