Few days ago I received a question - how big an egg can possibly big? Can it be as big as 1 meter, as a human? (Imagining that there could be really huge animals which would lay these eggs)
My thoughts are that an egg should have an upper limit and basically you can find out the biggest possible egg for Earth. By big I assume the biggest volume.
I started to think this way - the thing inside the egg should breath, therefore the egg should allow CO2 and O2 to go in and out. The thing inside the egg consumes constant amount of O2 which is related to the volume of the egg. On the other hand the surface of the egg is related to the amount of air the baby can breath. But with the increase of the size of the egg - the volume is growing much faster then the surface. So at some point of time the amount of air going inside of the egg would not be enough.
I think that I am on the right track, but can not finish it to receive the answer.
P.S. I hesitated about the Math.stackexchange and physics, but assumed that this one is more applicable but please feel free to move it to math if you think it is better
