 And so it's almost like a sort of an Earth's orbit around the Sun. But what we're talking about here is Earth's orbit around its interdifferent stable states. And so we have the big glacial state. And then every 100,000 years, we will push into another orbit. The gravitational forces will pull us into a different state, these interglacials. So we try to depict this as these cycles every 100,000 years.
