No credible astrophysicist believes that the center of a black hole consists of a single massive atom composed of normal matter (protons, neutrons, and electrons). Instead, the center of a black hole is thought to be a singularity, a dimensionless point with infinite density. Not only atoms, but the subatomic particles that atoms are made of, would be crushed under such extreme conditions.
Regarding the formation of a new universe from a black hole: Since no black hole has been observed to decrease in mass, the mass inside the black hole must still be in this universe. However, it's impossible to know exactly what happens at a singularity, and some scientists believe that it's *possible* that a singularity could lead to another universe. Some of these "multiverse" theories include string theory as a key concept, but Dr. Tyson is a critic of string theory and would certainly *not* accept them as valid.

As to what he does believe, who knows? For honest people who aren't string theorist, theoretical mathematicians or religious, the best answer to where the Universe came from is: I dunno.
Dr. Tyson knows an awful lot about what happened in the first few microseconds after the Universe was born, but not what actually happened at the moment of creation, to say nothing about what happened "before" - especially since there was no before! Not only was the stuff in the universe created at the Big Bang, but the universe itself was created: space AND time! There was no empty space waiting to be filled before and there was no before before. Ahem. You get the idea.
Being an astrophysicist, Dr. Tyson might be leaning towards two giant extra-dimensional membranes colliding together creating the Big Bang and the universe. And he might even agree that there's nothing in the mathematics to suggest that this can't happen over and over again, thus creating billions of multi-verses. The mathematics is lovely and does definitely suggest what is possible, but there isn't any evidence for any of this and maybe there never will be. For those that believe in a god, the poetry of creation is lovely and suggests a wonderful possibility, but there isn't any evidence for any of this and maybe there never will be. This may simply be "beyond human science."

"What, you might ask, could possibly induce a rational astrophysicist to believe that all the matter, energy, and space of the universe began fifteen billion years ago in a primeval fireball packed into a volume smaller than a marble that has been expanding ever since? The answer is simple: regardless of what you may have read or heard, the big bang is supported by a preponderance of evidence and has become the most successful theory ever put forth for the origin and evolution of the universe."
I don't think we're going to see such an outspoken scientist believe such a unverifiable claim. Anything that happened before the universe is by definition unobservable.
If you follow the link to my source you can find his arguments to support this statement.

Mahalo is adding a tip to all questions that don't offer a tip.
Does Neil deGrasse Tyson think that a Universe is born from a densely packed atom created from the remnants of a blackhole?
Where the atom created by the blackhole immense power is pushed into what is essentially a new dimension "universe". So in that respect as there are billions of galaxies, can't there also be billions of universes too?

In a quote from his own article: "What, you might ask, could possibly induce a rational astrophysicist to believe that all the matter, energy, and space of the universe began fifteen billion years ago in a primeval fireball packed into a volume smaller than a marble that has been expanding ever since? The answer is simple: regardless of what you may have read or heard, the big bang is supported by a preponderance of evidence and has become the most successful theory ever put forth for the origin and evolution of the universe."
