It's AumSum Time.
What if Earth Doubled in Size?
Wow.
Will my burgers also double in size?
Stop it AumSum.
Diameter of earth would increase from 8,000
miles to 16,000 miles.
If the density of earth remains same, then
its mass will increase 8-fold.
Earth's gravity will naturally double.
This will have major consequences.
Firstly, our weight will double.
All the gyms will definitely see increased
enrolments.
Secondly, our bones will not be able to support
our increased weight.
Thirdly, our hearts will have to work double
hard.
To make sure blood reaches all the parts of
our body.
Fourthly, birds, airplanes, choppers will
all fall down to the ground.
Fifthly, trees will not be able to stand upright,
most of them will 
fall down.
Finally, if we fall down, it will hurt twice as much.
