So You Think You Know Gravity? Let Us Drop Some Knowledge

But maybe a better way to approach gravity is to think not about being stuck on Earth but about being weightless.“What you’re really doing when you’re experiencing gravity isn’t being heavy in your chair, it’s falling weightlessly in the gravitational field,” says astrophysicist Janna Levin.

For Fantasy Author N. K. Jemisin, World-Building Is a Lesson in Oppression

In a lot of cases, to understand the character I need to understand literally everything about their world.” To do so, she applies two frameworks: one that focuses on macroworldbuilding (the creation of the physical environment in which the story will take place—planet, continents, climate, ecology, and culture) and one that focuses on microworldbuilding (the societies that result, in all their flavors of social stratification).

Whoa! Is That Death Star Wreckage on That Planet?

As this equation shows, the magnitude of the gravitational force depends on the mass of each object (m1 and m2) and the distance (r ) between them.Think of the planet and space object as a system, where the total energy in the system is constant—there’s no external force acting on it.

We have the Voyager program to thank for some of this week’s spirals: When Voyager 1 first flew past Jupiter in 1979, it photographed the monster tempest swirling around and over on itself, and in 1989 Voyager 2 flew past Neptune and spied a small spiral storm that NASA nicknamed “Scooter.” Farther beyond are galaxies like our own spiral that contain gorgeous illuminated arms speckled with starlight.

The Bizarre, Peaty Science of Arctic Wildfires

That, though, would require forest management across swaths of the Arctic, a kind of management we in the US can’t even do right on a small scale .What we’re looking at, then, is yet another complicating factor in the massive complexity that is climate change: When peat burns, it emits lots of CO2, and when peatlands aren’t healthy, they don’t capture any.
