A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Posts must be original/unique
- Be good to others - no bigotry - including racism, sexism, ableism, homophobia, transphobia, or xenophobia
- Adhere to Lemmy's Code of Conduct

Is inside the atmosphere really space though? Sure, in the sense it has a volume, but that's not what people mean by space
The Earth's gravity well extends far beyond the atmosphere. The moon is for example is well inside the gravity well and even the hill sphere meaning Earth's gravity is the dominant gravity force on the moon.
Earth's gravity extends to infinity, even though extremely small. There is always gravitational attraction between two objects.
Atmosphere might be better measure
Technically speaking, the gravity well is finite in diameter and is defined as where gravity reaches the “meh” level.
Right, but gravity well isn't the boundary where outer space begins. The moon is clearly in outer space, so I'm not really sure why you'd suggest that "within the gravity well" would be inner space. In fact, Earth's gravity well never ends, it simply diminishes with the square of distance. The entire universe is within Earth's gravity well, so where would you even put the boundary? Where Earth is no longer the largest gravitational force?
Anyways, it doesn't matter because as you clearly demonstrated, it can't be related to gravity.
