${}$Hawking radiation and Einstein-Cartan theory As I understand it,  Einstein-Cartan theory predicts that inside every black hole, there is an einstein rosenbridge connecting to a new universe that forms due to a white hole.
Where does hawking radiation come into play? Ie, does hawking radiation act the  same? And if it does, what happens to the created universe once the black hole has fully irradiated?
What would it look like from the created universes perspective? Would mass be exiting the new universe to be transported outside the event horizon?
There are lots of similarities with this theory and the big bang, it gives a connection between the white hole  and the big bang, and gives a mathematical REASON that there is an expanding universe on the otherside of the black hole.
Could the universes expansion, specifically when the expansion of space is faster than light (ie we can never interact with it) be indicative of mass leaving our universe due to hawking radiation?
 A: I don't have any particular expertise in Einstein-Cartan theory, but I would caution against taking it seriously as describing real astronomical black holes. Even the simplest black hole solution, due to Schwarzschild, includes a time-symmetric white hole.  But it's not a solution for a black hole that forms by collapse; which is very time-asymmetric.  A Kerr black hole also is a theoretical solution that contains connection to other universes.  But that doesn't mean a rotating black hole formed from collapse of a star has that internal stucture.
A: You said: "As I understand it, Einstein-Cartan theory predicts that inside every black hole, there is an einstein rosenbridge connecting to a new universe that forms due to a white hole."
This statement is wrong. Read about Einstein-Cartan theory  and wormholes .
You have asked:"Where does hawking radiation come into play? Ie, does hawking radiation act the same? "
Hawking radition is commonly associated to the event horizon of any black hole. It's generalization for any theory of gravity is known as the Wald eneropy.
You have asked:"And if it does, what happens to the created universe once the black hole has fully irradiated?"
Your concern is right but only in the sence that the Hawking radiation leads to evaporation of the black hole and causes the loss of information.
With all due respect, I lost my apetite to read the rest of your post.
