How many days to wipe us all out?

Question

Hi! You've probably heard of the riddle concerning putting one grain of sand on the first quare of a chessboard and then seeing how many you put onto the last square, but here's a twist.

The world population is the total number of living humans on Earth at a given time. As of June 21, 2008, the world's population is believed to be 6,704,845,726.

This is from Google.

So, if one person caught a fatal contagious illness on day 1, how soon (supposing people with the desease were fleeing all over the world to escape it) would it take to wipe out the whole human race?

Answer 1

some kind of illness is very unliky of killing off all human life as tehre will always be some due to the wideness of our gene pool as a race that will be immune, we are more likly to be killed off by nuclear war or famine (future)

Answer 2

28 weeks or 28 days

lmao

Answer 3

wouldnt it depend on:

-how it was spread?

-where it started?

-how quickly the rate of diagnosis and symptoms showing was?

-how long does it takes to die from it?

-did anyone hide in a bunket sealed from the world?

I reckon it could take a while...Im hoping someone would find a cure :)

Answer 4

i doubt a disease would wipe everybody out, a handful would probably be put up somewhere remote and let the population die out till they could come out again, asteroid would prob be the way to go for population destruction

Answer 5

Not trying to be funny but probably 28 days.

Answer 6

Wow! Thats not cool!

Answer 7

About 24 hours.

now where`d i put that cyanide pill?

Answer 8

25 years, but I am sure they would kill that person before it got around the who world so that is would stop

Answer 9

Right now there is an estimated time to our earth's life, but really no one really knows... sorry!

P.S: The earth will end in flames rather than a desease according to scripture.

Answer 10

It depends on how contagious this illness is , how it is spread, which populations are more vulnerable to this disease, and also, more importantly, the rate at which the disease spreads.

Answer 11

maybe about a month and a half, or lesss like three weeks.

Answer 12

it's quite unlikely as the diseased person would be hospitalized very quickly if the disease were really fatal. Anyone smart who was around that person would know to go to the hospital to be checked out as well.
