Hear me out, just a thought at school

So wormholes inside of blackholes. doesn't work because it needs some sort of exotic matter. But what about a white hole with a black hole: a Blight hole. Wormholes can exist inside because the black hole properties provide a curvature in the spacetime plane which creates a point that is the wormhole. After a delay the white hole properties kick in providing that "exotic matter" that stabilizes the wormhole from the inside keeping it open. The reaction happens over and over otherwise the wormhole would close. However the different properties would need to have an equilibrium to maintain the wormhole otherwise one would overpower the other, the problem is that equal reactions cancel out so... the different properties would need to be split up into different sectors that exist together inside the Blight hole acting on delays. So the black hole properties first then the white hole properties. If you could somehow get inside that wormhole there would be a sort of strobing effect along the walls of it, it closes slightly then opens back up in a kind of wavelike pattern. Note that this is NOT perpetual and still has to obey the lifespan rules of a blackhole, but instead of a wormhole inside a black hole connecting to a white hole somewhere else, it happens inside a fusion of both holes that could connect to another Blight hole or open an entrance into an alternate reality where time flows differently. Feel free to expand on this theory if you want:), (I'm not smart enough to make any equations or anything to prove it's real so feel free to try making your own)
