MO-1 / THE SKY

The sky you’re
born under.

Every birth is a big bang: from where you stand, the universe just started. But when you spawn changes what you get. Drag the age of the cosmos and see the sky a body born then would see.

13.8 billion yearsNow

The glow is 2.725 K, stretched into microwaves. You can't see it, but it still comes from every direction; a little of the static on an old analog TV was this light.

MO-1 / TWO CAPTAINS

Same gravity, different orbit.

Two captains with the same pull. The sun captain gives light: the bodies around it orbit freely, sail off to explore, and come back because they choose to. The black-hole captain takes: its bodies spiral in, dim, and can’t leave. The question isn’t how much pull you have, but whether your orbit captures or frees.

Sun captaingives light

Light pushes out. Bodies trim it like sails: they orbit free, sail off, and choose to come back.

Black-hole captaintakes

Drag pulls in. Bodies spiral down, redden and dim; whatever crosses the dark stays.

Freed: 0Taken: 0

Throw one. Drag on either sky to aim, let go to throw; a tap sends a body into a gentle orbit. Keyboard: the Launch buttons. Same throw, same pull: watch where each captain takes it.

Keeping count. Freed counts trips out past the edge of the picture; each traveler comes home. Taken counts bodies that crossed into the dark; none come back.

What’s the same, what’s added. Both skies start with the same eleven bodies around the same central mass. The sun adds a push of light the bodies trim like sails; the black hole adds a drag that thickens toward its center, and a horizon.

A picture, not a simulation of real stars: same pull, different gift.

How it works

One stretch, one number

Space has been stretching since the start. The leftover glow of the Big Bang stretches with it: when space was 1,100 times smaller, the glow was 1,100 times hotter. Today it’s 2.725 K. The ages come from the standard model of the universe (flat, with dark energy; the Planck satellite’s 2018 numbers).

Where did the energy go?

Energy is conserved because the laws stay the same from one moment to the next. A stretching universe isn’t the same from one moment to the next, so at the scale of the whole cosmos the promise lapses. Each photon of the first light has lost 99.9% of its energy, and nothing received it. A body born late inherits a colder universe, with less difference left to work with.

What’s computed, what’s drawn

Computed: the glow’s temperature, its color and how bright it looks to a human eye, the size of space, and the age of each moment. Drawn: the stars and galaxies are a fixed picture that fades in when the first stars light and fades out as the other galaxies slip away.
