Check out this fascinating site to see what astronomers think is the most detailed map yet of our place in the universe.

It boggles the mind.

How long would you estimate it would take you to walk around the equator? (don't look it up first).
How long would it take to drive to the moon?
I'll admit I have no idea on either question. I will guess about a year for each.

Calculations to follow.

Earth has a circumference of about 40000 km. Walking at a steady 5 km/hrs this will take you about 8000 hours, or 333 days. Since it isn’t wise to walk for more than 12 hours a day (I guess), you have to accept that this will take about 666 days (The Devil is behind this!!). Or, you could do the smart thing, and not begin the walk at all 🙂

Why can't you guys stay on topic?
We're supposed to be discussing the shape of the universe. Surely you can come up with some real knowledge about it!
This was very much my comment as to "shape of the universe".
Do you have any responses to this, or are you just forging ahead with what you want to say?
