We're going to find Marses and maybe Earths out in the solar system's attic of the Oort Cloud and the Kuiper Belt.

Those fields of daisies we landed on, and dusty fields and desert stretches. Memories of many skies and earths beneath us - many days, many nights of stars.

Geoengineering involves humans making intentional, large-scale modifications to the Earths geophysical systems in order to change the environment.

Because of Hubble and other telescopes, we've now discovered that there are probably planets around every star, or virtually every star. There are solar systems around most stars. And the fact that we're here on a planet, Earth, means that it's likely there's lots of other Earths out there.

[first lines]
Serafina Pekkala: There are many universes and many Earths parallel to each other. Worlds like yours, where people's souls live inside their bodies, and worlds like mine, where they walk beside us, as animal spirits we call daemons.
Stelmaria: Are we going to see the child?
Lord Asriel: I should think so.

Serafina Pekkala: So many worlds. But connecting them all is Dust. Dust was here before the witches of the air, the Gyptians of the water, and the bears of the ice. In my world, scholars invented an alethiometer - a golden compass - and it showed them all that was hidden. But the ruling power, fearing any truth but their own, destroyed these devices and forbade the very mention of

Dust. One compass remains, however, and only one who can read it.
