Humans have a total biomass of 3.9×10^11 kg. Let’s assume our titan is magically immune to collapsing under its own weight. At human proportions, let’s say a BMI of 20 for simplicity’s sake, it would have a height of approximately 139,642 meters, aka about 140 kilometers or 87 miles. This is far taller than any mountain and would put it above the Kármán line, the conventionally agreed upon edge of space.
Awesome. For your efforts, I will now tell you the story of why I was afraid of the Wampas Cat for years.
When we were little, any strange sound we heard out in the woods or just pretty much any sound we could hear but not identify, my dad would act all guarded and suspicious and say “I hope that’s not a Wampas Cat, actually I think it is” “don’t go over there or you’ll get got by the Wampas Cat” to me and my brother. It took a few years for us to realize that the Wampas Cat wasn’t real and it was just a play on Cattywampas.
You might use this what-if as a starter.
At the start of the scenario, the entire Earth’s population has been magically transported together into one place.
This crowd takes up an area the size of Rhode Island.
With a population of 8 billion, that makes a cube 2,000 people on each side.
But that would have a lot of empty space between people, so let us just say it would be 1,000 times as big in height, depth and width.
Pretty big titan
on that day, mankind received a grim reminder…
