Was our universe created from a black-hole?

How was our universe created? Some say it was created in a violent explosion known as the big-bang, while others say it originated forever. Here I thought what kind of a mystery is this? No human or nothing existed that time to have the evidence. But what if there was a universe before our own with probably galaxies & stars like our own or it could have just mass and energy and well, that universe would also have had super massive black holes like our own, one of which could be about thousand times the mass of our galaxy. As that universe would have progressed, its black hole’s power would also have increased and finally it would have gone on to swallow the entire universe around it. Finally it had no mass for gravity to exist. But radiation while entering the black hole could have triggered the black hole to start expelling the material inside. The force anti-gravity was thus created. So, the black hole must have, vomited out material when it had no space to keep that material inside and may have resulted in the big-bang and created our known universe some 13.7 billion years ago. And as the mass uncrowded in space, the black-holes density decreased and finally it had just enough density for gravity to come into existence, and then stars, planets and all that we see today were created. Dust, broken rocks, and pure form of mass and energy are some forms of proof of existence of previous universe. If I have sounded convincing, you, me, the planets & the galaxies were created from a black hole.

 How I got to this conclusion?

I believe our universe was the result of another higher dimensional universe which had profound effect on our space-time and what better could describe events that occurred and the fact that the universe is expanding a white hole which would, in fact, obey the law of entropy and thermodynamics which suggest that information cannot be destroyed and the big bang suggests somewhat similar possibilities as well.
