Recursive universes?
It's a pretty cool idea.

It could be! But the implosion need not be SWIFT.

I don't think so. From what I understand, a white hole is basically a black hole progressing backwards through time. Black holes don't explode once their formed. So I don't think a white hole would collapse on itself.

Now... black holes do that weird thing where they capture one half of a virtual particle-antiparticle pair, and therefore "evaporate". I think this is called Hawking radiation. What would the equivalent of that be if you were going backwards in time? Would a white hole give off matter seemingly from nowhere while simultaneously taking up virtual particles to increase its mass?

For a white hole, the effect would have little impact, I guess, since the particles would annihilate with whatever's going OUT, and generally do little to the white hole itself. No such thing about a point of no return with white holes, unless it's a point where it takes infinite amount of energy to push INTO.

The effect has a greater impact on black holes because of the size of their event horizon(and gravity well outside that as well, for larger virtual particles) relative to the amount of matter they are taking in, so when they capture half of a pair, they lose mass through quantum effects. Since space is mostly empty, once the black hole has consumed it's immediate surroundings(which increases the size of the event horizon, accelerating Hawking radiation), it no longer takes in as much mass as its emitting through the virtual particle effect.

Still think of the universe as a star they expand and expand till they implode on them selves

Stars expand for different reasons though, since a star expands due to the energy generated by their gravity implosion(and changes in size for that reason as well) induced fusion. Over the course of their lifespan, they generate different amounts of energy as their preferred fusion fuels run out, and destabilises at certain points.

Whether they explode, implode, explode THEN implode or just putter out depends on how they finished.

if it does explode or inplode it would be cool to watch until you die
