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.

Jagadheep built a new receiver for the Arecibo radio telescope that works between 6 and 8 GHz. He studies 6.7 GHz methanol masers in our Galaxy. These masers occur at sites where massive stars are being born. He got his Ph.D from Cornell in January 2007 and was a postdoctoral fellow at the Max Planck Insitute for Radio Astronomy in Germany. After that, he worked at the Institute for Astronomy at the University of Hawaii as the Submillimeter Postdoctoral Fellow. Jagadheep is currently at the Indian Institute of Space Scence and Technology.
