I need some elbow room.
Although the population density of the universe is zero (area is infinite and the population finite, finite number divided by an infinite number is close enough to 0 ) and any people you by chance come across are merely a figment of a deranged imagination… but yet it is feeling awfully crowded down here.
I am setting out today using first order calculations that we have in fact filled the earth The facts:
Surface area of a sphere S=4(pi)R2 radius in meters
Radius of the earth 6378 km
Habitable surface area (not ocean, desert, or ice) approx 20%
Amount of space required to sustain a single person enough space to be comfortable and self sufficient (vegies and some live stock) approximately 25 m2
Current population estimate 6,552,533,873
Firstly we need the surface area of the earth
Surface area of the earth = 511252214.112
* 1000 to m2
OF which habitable, so, not a desert, not an ocean, not too hilly, habitable is approximately 20% of the surface.
(20/100) *5112252214112= 102250442822.44 m2 of habitable land
divide the total habitable land by the land to sustain an individual
102250442822.44 /25= 4,090,017,712 individuals
APPROX 4 BILLION INDIVIDUALS AT CAPACITY…. Currently sitting at 6 billion.
Not a bad 8000 years effort filling an entire planet. I sometimes wonder if Adam and Eve were shown a random cross section of the people today; the whiny, self-important masses known as the human race. Do you think they would have bothered?
