1. Yes, the math has been done and discussed.

Just in case it wasn't quite clear, I was hoping for somebody to post what those chances actually were, or a link to a relevant and verified discussion with actual information on the topic. So far all I've come across is speculation about it.

Has anybody been able to work out the fractional chances of a collision with an existing bitcoin address?

Has anybody got any verifiable proof that it's been done in the past?

What hardware would be capable of even getting close to being able to generate enough addresses to cause a collision, and how would somebody trying to cause a collision notice that they've succeeded?

2. No (assuming you have a working RNG and non-buggy software.
3. None. If the address had been used they would see it.
