This is Scientific American 60-second science. I'm Julia Rosen. Got a minute?

Isaac Newton said, I can calculate the motion of heavenly bodies, but not the madness of people.

He meant that while people can be unpredictable, the planets are just the opposite.

They glide through space in orbits defined by the laws of physics.

But that view's been changing over time,

and a new study bolsters a more complex outlook.

The big finding of this paper was the discovery

of the first real, firm, unambiguous,

geologic evidence to confirm this idea

that the solar system is chaotic.

Stephen Myers, a geoscientist at the University

of Wisconsin-Madison. By chaotic, Myers doesn't mean that the planet zoom around wildly on

random paths. Rather, he's referring to the mathematical meaning of the word, in which the future state

of a complex system depends strongly on its initial conditions. In this case, it means that seemingly random changes

in planet's orbits can occur because of subtle gravitational interactions between objects in the

solar system. It's also known as the butterfly effect, right? So this is the exact same phenomena.

The idea that a butterfly flapping over the Indian Ocean could influence weather
