if rogue planets exist then inevitably one of them is going to get caught in orbit around a black hole, and I would have to guess that stars rotating a black hole probably lose hold of some of their planets which then end up rotating that black hole instead of the star.

The kind of travel you envision will require amounts of power that we currently are incapable of generating.

Certainly, we're the kind of planet that has aliens passing through lock their spaceship doors, just in case...

Where they found four different planets orbiting around a giant black hole.

The science is sound. There's no reason planets couldn't form beyond the snow line. Most radiation put out by a super massive black hole is directed out along the magnetic poles - it isn't going to go sideways into the accretion disk. And black holes don't really have anything very similar to a solar wind. Once protostars finish up into main sequence fusion territory, they blow out gas and dust like a cosmic leaf blower. Black holes tend towards the opposite.

I'm a little surprised this was a surprise. I assumed this happened. But now that you shared the article, I guess I never have really read an article about it. Kind of neat. Probably no chance of forming life though. A lot of radiation in those parts in general.

There is some speculation that planet "X" in our solar system could be a black hole which would possibly explain why it's gravitational presence seems to be felt yet it has not been discovered (it would be extremely small in size given it's calculated probable mass).
