Infinite playground.
TLDR: you can have a mathematics that always gives true answers (but that cannot answer everything). Or you can have a mathematics that can answer every possible question (but some answers are wrong, you do not know which). Choose.
This dispaired mathematicians of the early 20th century, who had hoped to create 'one mathematics to rule them all'. Of course you can have several disjunct mathematics, each one for the problem you like.
Book recommendation: Gödel, Escher, Bach by Douglas Hofstadter.
Of course we'll perceive things as complex when we move outside of that regime.
Knowledge - expands, Space exploration knowledge - expands, Sub atomic exploration - expands, (muon and we may even find its sub atomic particles as well) Space - expands, Number series - expands, Fibonacci - expands.
Be warned when something expands, it's a trap.
Science expands external knowledge and shrinks self-knowledge, Spirituality shrinks external-knowledge and expands self-knowledge.
Be warned when something expands. Be warned when something shrinks.
E=mc^2
where c is not just the speed of light, c is the speed of space expansion as well.
Mass expands to form energy (star)
Energy shrinks to form mass (black hole)
