If you look at the sky at night and fix your eyes on 1 point how many square miles are you seeing?How many square miles does the average persons eye see when looking at the sky at night?
So. Please not to think of area. Please to think of time. Many, many light years. Some people see nebula in Orion. Many thousands light years away.
Area is meaningless. Time is what see.How many square miles does the average persons eye see when looking at the sky at night?
Toshi is right, but he didn't really explain why. For example, if you can see the moon, our side of its surface area is about 18 million square kilometers. If you can see Mars, our side is 70 million square kilometers. Those are tiny compared to stars. So for each star you're seeing a surface that's trillions of square kilometers. If you can see hundreds of stars at a time, you're seeing quadrillions of square miles. What does that mean? Nothing!
You're not looking at area when you look at the sky. You're looking at a huge volume of space, bounded by the horizon and stretching millions of light years away in distance (just with your unaided eye). Billions of cubic light years, way beyond the tiny measurement units we use on the surface of our tiny little planet.
Over 9000 surface units
