In the movie Interstellar, if I remember right, they explain that a group of scientists was sent to the system on the other side of the worm hole, before the ship and crew we witness in the movie. One for every planet that had the potential to host a human colony. While the planet near the event horizon is of course of great scientific interest, they knew about the time dilation problem in advance.

So why did they send a scientist to it in the first place? Even if the planet was habitable (what would be strange enough), it would make no sense to colonize it. To eplore it or to prepare it for colonization would take 1000 of years. And if humanity colonizes it, they would effectively fast forward through the universe. The remaining lifespan of the sun of the system would be mere a few 1000 years I think (still a long time, ok). And shouldn't there be hard radiation? Every infrared photon should be shifted to high gamma rays when hitting the planet surface. And I think there are so much more problems and reasons.

So why wasn't the planet skipped completely in the first place?
