#### (#8) There Are Maybe Other Universes Out There That Got Their Start The Same Way

If our universe exists in a black hole, it could be just as easily argued that other universes exist inside their own black holes as well.

However, while Poplawski's theory explains the Big Bang and the origins of our universe pretty succinctly, it doesn't reveal much about the parent universe. Where did it originate?Has it always existed, or did it form just like our universe? In short, how many nesting dolls are there with these black hole universes?

University of California Davis physicist Andreas Albrecht says there won't be an answer anytime soon. "There're really some pressing problems we're trying to solve, and it's not clear that any of this is offering a way forward with that," he told National Geographic.

#### (#6) Poplawski Calculates That Matter Expands At A Rate Of 1.4 Times Its Size In Less Than 30 Seconds In A Black Hole

According to Poplawski, the numbers have it. His calculations prove beyond the shadow of a doubt that torsion plays a part in the Big Bang. As matter reaches peak density in a black hole, torsion runs contrary to gravity which prevents it from compressing infinitely to a singularity, as Einstein believed.

Instead, matter "bounces" and starts to expand. Poplawski's calculations show that matter expands 1.4 times its size in less than half a minute, which is how he believes the our universe came to be.

#### (#4) An Amended Version Of Einstein's General Theory Of Relativity Supports The Idea

Einstein's general relativity describes any and all events in the universe as occurring at one specific point in space and time. Theoretical physicists have long been grappling with combining the theory of relativity, which describes the universe on a larger scale, with quantum mechanics, a theory that examines the universe at its smallest levels, like the atom. By combining the two theories, theoretical physicists would be able to study "quantum gravity," which would help illuminate the mysteries behind certain phenomena, including what happens to matter once it enters a black hole.

While the original theory of general relativity does not support Poplawski's idea, an adaptation of Einstein's theory which takes into account the effects of quantum mechanics does. This adaptation, called the Einstein-Cartan-Sciama-Kibble theory of gravity, takes the important quantum property known as "spin" into account.

Atoms and electrons spin with "an internal angular momentum that is analogous to a skater spinning on ice," according to Poplawski.

#### (#10) There Are Other Theories Explaining The Chaos Of Our Universe

Our grasp of the universe - while growing - is still no bigger than the alleged god particle. Theoretical physicists, cosmologists, and astronomers have been grappling with the mysteries of the universe since the dawn of time. Some of these members of the scientific community have come up with some pretty convincing (and sometimes horrifying) theories explaining various phenomena in our universe.

#### (#7) The Rotation Of Black Holes Feed Into Poplawski's Theory

One way to know for sure if Poplawski's theory works is to look at the rotation of a black hole and its corresponding universe. If a universe was created inside a hole, the universe in question should rotate in a similar fashion as the black hole itself.

While measuring a black hole's rotation precisely is not something we can do just yet, if future findings prove correct, it could lend credence to Poplawski's wormhole theory - that black holes are just passageways from one reality to another.

#### (#1) A Black Hole Doesn't Collapse Everything - It Spits It Out At A Different Point In Spacetime

Black holes are inescapable regions in spacetime. For years, many believed anything sucked into a black hole by its strong gravitational pull would collapse, eventually folding into the black hole's singularity, or densest point.

While it is impossible to study what actually is in a black hole, Poplawski has an idea: what if our universe exists in a black hole inside of another universe?

Poplawski believes matter is carried via an Einstein-Rosen bridge, AKA a wormhole. According to Poplawski, the opening of a wormhole is a black hole, and on the other side is a "white hole." When the matter enters a black hole, it travels to a different time and space and is spit out through the white hole. The matter then expands to form another universe.

### About This Tool

In 1916, the German astronomer Karl Schwarzschild calculated a vacuum solution for the Einstein Field Equations, which showed that if the actual radius of static spherically symmetric star was less than a fixed value, strange phenomena would occur around it, that is, there is an interface -- a “horizon”, into which light can not escape. This value is called the Schwarzschild radius, an “incredible object” named by American physicists John Archibald Wheeler as a “black hole”.
