| There is an aleph1 number of real numbers
That is a statement of the continuum hypothesis, which is known to be
independent of ZFC (the Zermelo-Fraenkel set theory including the
axiom of choice, on which we tend to imagine all of modern mathematics
is based).
| and an aleph0 number of non transcendental numbers (since we can
| enumerate all algebraic equations). Aleph1 > aleph0, an aleph1
| number of transcendental numbers remain. Right?
For aleph1 substitute c, and all this is true (where c is the
cardinality of the continuum: c > aleph0 as Cantor showed with his
diagonal argument).
