I'd like to call Kaku a pop physicist. He's a scientist who appears in media to make science appeal to larger audiences. So in other words, to make science look "amazing".
Anyway, a rogue black hole is extremely unlikely to draw close to us. Even more rare than a rogue planet and apparently, there are more of those than stars in the sky. It's more likely for us to get hit by a meteorite, which would be your first scenario.
So in the unlikely event that we were remotely close to a black hole, everyone dies instantaneously, there is no "three weeks", there is absolutely no amount of time you could spend. Not even a fraction of a second. This thread then becomes pointless in a serious situation. Congratulations, you successfully killed everyone, but you didn't give them enough time to survive and torture themselves over it.
Please try again.

Antimatter
Particle accelerators produce matter. They also produce antimatter. When matter and antimatter bump into each other, the result is total annihilation. While antimatter doesn't normally float around our atmosphere, it can be manufactured in small amounts inside a particle accelerator—including the Large Hadron Collider in Geneva, Switzerland. Manufacture enough of it, release it into the atmosphere—purposely or accidentally—and, well, it's goodnight and good luck for everyone.
They just released it into the atmosphere.
