What would you change about physics if you could? Me, I would make gravity a lot weaker, so we could have a way bigger Earth.

For all it's magnificence, I think Earth is way too small. Imagine if it was 10-20 times bigger. You could have deserts or jungles that would stretch to tens of thousands of kilometers. Current Earth is disappointingly small, and biomes are not big enough to feel "endless", especially as humans have conquered all of Earth. With Big Earth, the plant would feel truly massive, and even flying around it would take months. How cool is that!? There would still be uncharted territories, and complete wilderness.

Thoughts?
