TINY HUMAN for scale.

Real science. Ridiculous scale.

A tiny human vs. the biggest, deepest, hottest things in the universe.

Tiny Human is a little astronaut with a big problem: everything is enormous. Each short video drops them into something unimaginable, like the Earth's core, Mars or the bottom of the ocean, usually with the Blorps tagging along and the Chromes trying to take over.

Season 1: Tiny Human vs.

Three missions, one very small astronaut. New episodes go out on TikTok, Instagram, Facebook and X at 7 pm New York time. Times below are shown in yours.

EPISODE 1

Tiny Human vs. the Earth's Core

We've only ever dug 0.2% of the way to the center of the Earth. Tiny Human tries to finish the job.

Sources
  • Mponeng gold mine: over 4 km deep, with rock up to 66 °C.
  • Kola Superdeep Borehole: 12,262 m deep and about 23 cm wide; drilling stopped when the rock reached 180 °C.
  • A fall through the Earth takes about 38 minutes (Klotz, American Journal of Physics, 2015).
  • Inner core: about 5,400 °C, roughly the temperature of the Sun's surface, under 3.3 to 3.6 million atmospheres.

EPISODE 2

Tiny Human vs. the Blorps: Who Gets Mars?

The first debate ever held on Mars. It did not stay civil. Then the robots landed.

Sources
  • NASA Mars facts: gravity 38% of Earth's, a day of 24 h 40 min, about −60 °C on average, two small moons (Phobos and Deimos), air about 95% carbon dioxide.
  • Blue sunsets on Mars were photographed by NASA's Curiosity rover in 2015.
  • Mars's surface area is about the same as all the dry land on Earth; the trip takes about 7 months.

EPISODE 3 · TWO PARTS

Tiny Human vs. the Mariana Trench

A race to the deepest point on Earth, 11 km down… and someone cuts the cable.

Sources
  • The Challenger Deep is about 10,935 m deep; Everest (8,849 m) would fit with about 2 km of water to spare.
  • Sunlight barely gets past 200 m, and between 200 and 1,000 m, 4 out of 5 animals make their own light (NOAA).
  • "Marine snow" really is bits of dead plants, animals and poop (NOAA), and Mars is mapped in more detail than most of our ocean floor.

Meet the crew

Every mission needs someone for scale, someone fluffy and someone shiny. Tap them; they talk.

Tiny Human

1.7 m · the size reference

A little astronaut with no face, so the person inside can be anyone. Brave, curious and slightly too small for everything.

The Blorps

knee-high · fluent in Blorp

Three fluffy, very confident creatures who are sure Mars is theirs. They only speak Blorp, so we add subtitles.

Blip · in charge
Bop · napping
Bix · plotting

The Chromes

twice as tall · twice as smug

Tall, shiny robots with a rocket, sunglasses and a business plan. They keep turning up wherever Tiny Human goes. It never goes to plan.

Facts, for scale

Small facts about enormous things, each checked against the source linked under it.

Tiny Human drives a little orange car straight up a road into space, next to a robot's rocket

Space is an hour's drive away.

Point your car straight up at 62 mph and you'd cross the edge of space, 62 miles up, in about an hour. Staying there is the hard part: the Space Station flies at 17,500 mph.

On Mars, you'd be about half your age.

A year on Mars lasts 687 Earth days. Try it:

Everest is the highest mountain. Not the tallest.

From its base on the seafloor, Hawaii's Mauna Kea rises more than 33,500 ft (10,210 m), most of it underwater. And the summit farthest from Earth's center is Chimborazo, in Ecuador.

Tiny Human's submarine at the edge of a giant underwater waterfall

The biggest waterfall on Earth is underwater.

Between Greenland and Iceland, cold, heavy water pours over an undersea ridge and falls about 11,500 ft (3,505 m), more than three times the tallest waterfall on land.

A blazing Sun fills a front doorway while Tiny Human holds up a tiny Earth

If the Sun were your front door, Earth would be a nickel.

The Sun is 109 times wider than Earth. At that scale, the nickel would orbit about 240 yards from your door.

The Blorps cling to Tiny Human in space near a small black hole

If the Sun became a black hole, it would be about 4 miles wide.

Earth would keep the same orbit (same mass, same pull). It would just get very dark and very cold. Relax: the Sun is far too small to ever become one.

The missions

Every episode measures something real against one tiny human, 1.7 m tall. Hover a mission (or tap it) to send Tiny Human along the ruler. Each step on the scale is ten times the one before.

Not everything is about size. The surface of the Sun is about 5,500 °C, roughly 150 times your body temperature. Tiny Human is going anyway.

MANTLE · 35 km

You are the tiny human.

The visor has no face, so the person inside is whoever is watching.

INNER CORE · 5,150 km

You made it to the center of the Earth. That's 6,371 km down and about 5,400 °C, roughly as hot as the surface of the Sun. Tiny Human is going to need a much better suit.
