So. Depending on where you are in the world there is a geologically direction. The Eastern Hemosphere. The Western Hemosphere. The middle east. So on so on. So what I wanna know is what exactly do these places start? Like where is the center? I know country to country it will be different. Like Texas is the Midwest in America but I’m sure it’s not the Midwest of the planet. Where do these places start geologically? Specifically for Earth and the US.

So magnetic north occurs naturally and we have compasses to point to it. With that bearing we can establish the rest of the cardinal directions. And we’ve known about this for a long, long time.
“Hipparchus, a Greek astronomer (190–120 BC), was the first to specify location using latitude and longitude as co-ordinates. He proposed a zero meridian passing through Rhodes.”
“In 1884, at the International Meridian Conference in Washington, D.C., 22 countries voted to adopt the Greenwich meridian as the prime meridian of the world.”
From that point on the world pretty much locked in it’s definitions of eastern and western based on the official new Prime Meridian. And that’s how Texas wound up being in Midwest of the Western Hemisphere.
