100×10^12 km is about 10.6 light years. There are about 16 other stars closer to the sun than that. It's a bit like a human body containing blood vessels with total length greater than twice the Earth's circumference.

Imagine if a 3year old has only one single blood vessel: The single blood vessel grows by approximately 88 kilometers per day since conception.

Here is the quick calculation using that timeline:

•Total Days: ~1,365 days (270 days in the womb + 1,095 days of life up to age 3).

•Total Length: ~120,000 kilometers.

That breaks down to an astonishing 3.7 kilometers of growth every single hour.

Typical adult walking speed: ~5 km/h . Next time you are walking then imagine the tiny thin blood vessel growing behind you almost at the same speed you are walking. If you slow down and stop it will catch up to you.

Interesting how deeply east coast Australia is colored. I live in Sydney, a city of 5.6 million humans, and yet my yard apparently has at least the following fungi I can identify to species level: Aseroe rubra (alien thing with tendrils), Astraeus hygrometricus, Cladia aggregata, Coprinellus disseminatus, Coprinellus micaceus, Cruentomycena viscidocruenta, Flavoparmelia caperata, Heterodea muelleri, Hypholoma fasciculare, Leratiomyces ceres, Mycena tenerrima, Myriostoma australianum, Omphalotus nidiformis (glows in the dark), Panellus luxfilamentus, Satyrus rubicundus (looks like a red penis), Scleroderma cepa, Scleroderma citrinum, Trametes coccinea, Trametes versicolor, Usnea hirta.

The map looks off. No way the American Southwest has 3 meters per cm cubed of fungal density in such an arid region. Plenty of desert.
