meteor

did a meteor the size of a football pitch hit the earth in the last few years

p.s nothing to do with the above but is it really true - that you can fit the population of the world - 10 times over - in loch ness (if it was empty!)

Not in the last few years as far as I'm aware but there was one in Russia in June 1908. This didn't hit the earth but exploded in the air. It knocked over approx 80,000,000 trees according to Russian records...

Your second question is easy to work out.
The volume of Loch Ness is 7,450,000,000 cubic metres.
The current population of the world is approximately 6,900,000,000 people.
So dividing 7.45 by 6.9 gives about 1.1 cubic metres of space per person.
But the volume of an average 70kg person is .07 cubic metres and so 1.1 divided by .07 gives 15. So your 10 seems reasonable - depends what you take as the exact figure for the population

I believe a meteor hit wiped out the dinosaurs. Just goes to show if you wipe out a species another will come forward to take its place. Maybe in the next wipeout life will be more diverse?
