I'm having a little 'geek' contest. The first person to answer all of the following questions correctly, gets 25 SG stickers. =) To keep comment spam to a minimum please only post once and any editted comments will not be accepted.

1) What is the absolute smallest measurement of time?

2) What is the absolute smallest possible distance?

3) What is the maximum distance that we can see?

4) What is the absolute maximum height for a tree on Earth?

5) What is the absolute maximum height for a mountain on Earth?

6) What is the absolute maximum wind speed of an Earth hurricane?

7) How much time does the Earth have left?

Good luck! Oh yes, I'll post the correct answers in 24 hours if nobody gets them.
