We have been talking about how big the universe is and have come to the conclusion that it is really REALLY big!!
As I said Room 1, I have a question (or two) for you. They are…
1) How big is an AU and what does AU stand for?
2) What is a light year?
3) Why can’t we, people who live in New Zealand, see “Northern Hemisphere” constellations?
First correct answer to all three questions in one post get the 2000HPS!!
GOOD LUCK!!
1. a mean distance between the earth and the sun. Astronomical unit.
2.how far light travels in a year
3.because the earth is round and we cant see stars in the day only at night and because we travel half a lap round (not around the sun) and at night we are facing the south not north and we cant see the north side of the earth so we can only see the southern hemisphare.
1) The distance between the earth and the moon. Astronomical unit.
2) The distance light travels in 1 year.
3) Because the southern hemisphere of the Earth isn’t facing north so we can’t see them.
You are correct on the light year, but not on the AU. You both have pretty much answered the third questions as well. It’s because of the earth’s curve we cannot see constellations or stars (like the North Star). First one to get the AU correct out of Alyx and Logan gets the 2000 HPS.
This is a very good little video. I also learned from it. I never knew that the planets were that big. Where you astonished when you found out how big each planet was?
Full of salient points. Don’t stop belieinvg or writing!
