If you go back in time as far as you can, you’ll find a Universe that was hotter, denser and more energetic. If you were to extrapolate back to an arbitrarily hot, dense state, the laws of physics that describe space, time, matter and energy break down; you’ll arrive at a singularity. Yet a singularity is also exactly what you find if you were to fly inside a black hole, to the final destination where all infalling matter and energy winds up. These are the only instances in the entire Universe’s history — past, present and future — where a singularity occurs. Perhaps the two of them are connected? It’s not as crazy an idea as you might think.
Similarly, you can take a black hole’s mass and calculate how big its event horizon is: the region where space is curved so severely that nothing, not even light, can escape. If you were to take a fundamental particle and allow it to be more and more massive, you’d very quickly reach a point where that particle’s Schwarzschild radius — a measure of its event horizon — was bigger than the Compton wavelength: about 21 µg, or micrograms. The fact that black holes in our Universe are much more massive than this isn’t a problem. It simply means that the laws of physics that we know break down at the singularity we calculate at the center. If we ever want to describe it accurately, it’s going to take a unification of quantum theory with General Relativity. It’s going to take a quantum theory of gravity.
As it stands, however, we can calculate what happens to spacetime inside the event horizon all the way up to (but not including) the central singularity. Surprisingly, with just a coordinate transformation, the space inside a black hole can be mapped, one-to-one, onto the space outside a black hole.
As the black hole first formed, from a star’s core imploding and collapsing, the event horizon first came to be, then rapidly expanded and continued to grow in area as more and more matter continued to fall in. If you were to put a coordinate grid down on this two-dimensional wrapping, you would find that it originated where the gridlines were very close together, then expanded rapidly as the black hole formed, and then expanded more and more slowly as matter fell in at a much lower rate. This matches, at least conceptually, what we observe for the expansion rate of our three-dimensional Universe.
Theoretical physicists from Munich's Max Planck Institute for Physics (MPP) have recently suggested that the mysterious black holes, which are among the top intriguing features of the universe, are actually just holograms, or optical illusions. The scientists reportedly have developed a new method for observing the chaotic states that occur beyond a black hole's event horizons.

Very interesting notion indeed. The fact that science is talking about things like the universe as a hologram, simulated universe and do we live in a black hole means we're coming out of Plato's Cave which in this case is the observable universe.

The video is saying matter falls into a black hole and then travels through a wormhole to another universe. So the black holes would lose mass and stop being black holes. Is there any evidence in the universe of black holes dissipating?
If matter could exit through a wormhole then black holes wouldn't really exist. Especially if you're talking about creating a big bang in another universe, that isn't a slow leak of energy, that would be the entire black hole releasing it's energy all at once. The gravitational influence of the black hole in our universe would immediately stop. So we wouldn't see the things we see in space like black holes draining stars or supermassive black holes in the center of galaxies.
Black holes seem to continue being black holes over time which means they have to keep all the mass that has entered them. Otherwise space-time would just flatten back out.
Also during the big bang space-time expanded, this is different than if a wormhole erupted a bunch of energy from a black hole. The black hole concept doesn't explain how an entire universe of space-time was crunched up to subatomic size (our universe) and why it had such low entropy among other questions.
In explaining his proposal, Dr. Guth likens the universe in which we live to the two-dimensional surface of a sphere which, because of its immense size, appears to us to be almost perfectly flat. There are circumstances, he says, in which an ''aneurysm'' could develop on this surface, a region in which space and time bulge like a tumor, eventually pinching itself off from its parent into a new universe.
To a hypothetical observer inside the bulge, conditions might initially resemble those of the Big Bang explosion from which our own universe is thought to have arisen. But to observers in our own universe, Dr. Guth said, the aneurysm would merely resemble a black hole - a supermassive object whose immense gravity prevents the escape even of light. After a certain amount of time the black hole would evaporate, leaving no trace of the place where a new universe had been born.

I had a similar idea, but decided not to post due to lack of time to write it up properly and the lack of time to do the basic research. I wondered if perhaps all matter would end up in black holes and turn into energy, that all black holes would merge and this huge amount of energy would cause an explosion that would through the explosion transform(from energy) into matter that we now see. The initial matter would be basic, but become this.
P.S. I'm not sure just how similar this is to your post. Apologies. On only a few hours of sleep at nearly 3 AM.
Theoretical physics is full of mind-boggling ideas, but two of the weirdest are quantum entanglement and wormholes. The first, predicted by the theory of quantum mechanics, describes a surprising type of correlation between objects (typically atoms or subatomic particles) having no apparent physical link. Wormholes, predicted by the general theory of relativity, are shortcuts that connect distant regions of space and time. Work done in recent years by several theorists, including myself, has suggested a connection between these two seemingly dissimilar concepts. Based on calculations involving black holes, we realized that quantum mechanics' entanglement and general relativity's wormholes may actually be equivalent—the same phenomena described differently—and we believe the likeness applies to situations beyond black holes.

When matter falls into a black hole, it's masss is spread across the event horizon. So all the information about the object that fell into the black hole is encoded on a 2D surface area or the event horizon.
What we call matter is crushed into a singularity but it never collapses into a singularity because of quantum mechanics. At the singularity you have particle pair production and vacuum energy grows and overtakes the effect of gravity in this singularity that has collapsed into a wormhole.
According to quantum mechanics, particle pairs are constantly appearing and disappearing as a quantum foam. In a region of strong gravitational tidal forces, the two particles in a pair may sometimes be wrenched apart before they have a chance to mutually annihilate. When this happens in the region around a black hole, one particle may escape while its antiparticle partner is captured by the black hole.

Eventually the repulsive force of vaccum energy would work against gravity and it's just like a can of pop. The pressure cause a big bang and a new universe fors. Professor Alan Guth talked about this back in 1987.

Like Guth and others said, it wouldn't take the black hole releasing all of it's energy as you say. It would just take a small amount of matter for a universe to form. Here's more from Guth:
''The odd thing is that you might even be able to start a new universe using energy equivalent to just a few pounds of matter,'' Dr. Guth said. ''Provided you could find some way to compress it to a density of about 10 to the 75th power grams per cubic centimeter, and provided you could trigger the thing, inflation would do the rest.'' In the space of less than a microsecond the new universe would inflate to enormous size and create for itself all the matter and energy it would ever contain. In all respects, it would resemble our own universe.
