Gravity Quote by Lee Smolin
““So, in the end, the most improbable and hence the most puzzling aspect of space is its very existence. The simple fact that we live in an apparently smooth and regular three dimensional world represents one of the greatest challenges to the developing quantum theory of gravity. If you look around at the world seekimg mystery, you may reflect that one of the biggest mysteries is that we live in a world in which it is possible to look around, and see as far as we like. The great triumph of the quantum theory of gravity may be that it will explain to us why this is so.””

Source Speech: Theoretical Physics Conference, 2015
The existence of a smooth three‑dimensional universe is a deep mystery that challenges quantum gravity, prompting the search for a theory that explains why space exists as it does.
In simple terms: Space’s existence is puzzling for physics.
Key Takeaway
Seek theories that explain why space is smooth.

I've also done some gravity tests with ZERO-G [a charter-flight service in Arlington, Va., that uses modified Boeing 727s to simulate weightlessness], which went great.” quote by Richard Branson](https://sms4smile.com/quotes/img-quotes/aa1/richard-branson-256_adventure_i-ve-used-the-phoenix-centrifuge-to-repl_903.jpg)
