Is it possible to create a valid adress without the private key?

Something I don't understand:

If I create I a brainwallet, I receive a public adress. Do I write the adress with this act into the blockchain (how??), or was the public adress there, before I created the brainwallet? Is every public adress availible to receive bitcoins, cause there's a limitation in possible public adresses, which can be calculated with the private key, so that it's impossible to type a valid public adress by randomly tipping?

(and do miner something like finding randomly public adresses?)


Simply speaking, all integers from 0 to 2^160-1 are valid bitcoin addresses. You can send bitcoin to any of these addresses. Miners don't know and don't care whether there is a corresponding private key for such address, until someone tries to spend.
