You feel the still stones, the firm ground, nothing moves beneath the sole. And yet tectonic plates shift every year between two and fifteen centimeters over the molten mantle, and that coast that seems eternal was once attached to another continent and will be again.  \r\n  \r\nThe continents have joined and separated at least three times in the last billion years. The last supercontinent was called Pangaea and existed two hundred fifty million years ago. The next one has a name, Amasia, and models place it within another two hundred fifty million years. The Atlantic is widening today by about two and a half centimeters per year, the same speed at which your nails grow.  \r\n  \r\nIf the plates move at measurable and real speeds, then something must explain why that movement is absolutely invisible from the inside.\r\n\r\nThis episode was created with artificial intelligence: AI-assisted script and AI-generated (synthetic) voice.","author_name":"Creators Obomedia"}
