Is there any possibility that the Solar System or the Universe is in a black hole? (Intermediate)

In our world, time always goes forward (one has not found a way to go back into the past), whereas inside the event horizon of a black hole (which defines the location where light cannot escape), the behaviour of space and time are inverted, meaning that space always goes forward (towards the center of the black hole). Whether you go forward or backward in time inside a black hole, you still go towards the singularity. Is our world like that? No. So we can safely answer that our solar system or our universe is not in a black hole.
