How is the provider to do that which has been shown impossible? When some provider actually has succeeded, only then is there a problem, but that has not happened, and cannot happen. So lets wait until it does before asking stupid questions about it.

The natural immediately following the one for the transposition that completes the simultaneous well-ordering and natural ordering of the rationals.

Garbage is never bright. I also choose not to try to understand why the sea is boiling hot and whether pigs have wings.

For numbers, such things only exist by belief in them anyway, so if enough people believe in 0.111..., then it does exist.

An edge must start at one (parent) node and end at another (child) node. Any proper fraction of one won't reach. In the set of naturals {} is the first. What does half of {} mean? Or any other fractional part of {}? |
