Oh, we're past the point of no return by 85,048,036 miles or so. As someone mentioned, the US is Wile E. Coyote, well beyond the edge of the cliff, running on air, attempting to defeat gravity, and we know who wins the battle, but we've been mid-fall for so long we think reality won't catch us.

The long descent fooled us into forgetting we're freefalling, and we're more delusional as we get closer to the end, but undoubtedly, Elon Musk will invent a device that will save us from gravity. Yippy!
