That was not described as a time portal! Please educate yourself more.

It was never clarified in the film that it wasn't also displaced in time, the novel of the film implies the probe was thrown centuries into the past. The "black hole" in question would also have been close to or even at the edge of our solar system, possibly some short lived event, so we already have a precedant of this phenomena, naturally occuring even, as far back as 1979 (2273).
