Every night, if the weather allows it, I sit outside to enjoy a few beers and alittle bit of grass. A few nights ago I was looking at the stars when one disappeared while I was focused on it. How can this be possible?

P=1000√t+2000 ( t+2000 both are under the sqrt)
(P) is for population

Using this equation approximate how many years it would take for the population to reach 7000. Round the nearest whole year when necessary.


I think the answer is 25 years but I need to know the step by step how to.......

Last night I was watching tv and saw tons of lighting outside. It was non-stop and there was also thunder. So I checked the radar to see what was coming--and there was nothing on the radar! The closest storms were probably 100 miles away. I thought maybe it was a fluke and maybe the radar wasn't updated so I checked a different radar and it didn't show anything either.

How could there have been thunder and lightning if the radar was clear?

then surely planets further out beyond pluto, like really far out, should be more advanced than earth as they have 'technically' been around for a longer time, they could be thousands of years ahead of us, and in a thousand years, this will be earth

on Aug. 27 when Mars comes within 34.65M miles of earth. Be sure to watch the sky on Aug. 27,2007 12:30 am(IST) . It will look like the earth has 2 moons.

The next time Mars may come this close is in 2287.

Share this with your friends as NO ONE ALIVE TODAY will ever see it again. *
