Can someone explain to me why charged and spinning black holes

Light sound zoom /proto-ism

speed (electrons) and photons (?quark)
same (≈)
light (maxwell) and sound (?doppler)

They only have one event horizon, the other one is a cauchy horizon or the ergosphere

Because maths.

But mayhaps math isn't actually everything. Or perhaps it's lacking

They say this is possibly by maths (at least in Steins;Gate), but shouldn't scientists already discovered something like it in space? And, are this kind of blackholes supposed to exist in the beginning of the universe like super massive ones or are they expected to exist after?

Finding a black hole isn't that difficult, but discerning any details is close to impossible.

The idea of primordial black holes has been researched, but doesn't so far seem to be supported. Last I checked anyway

I see... I wonder if it could really be made in laboratory...

If we could, the size would be so small that it would explode into hot energetic particles immediately.

If I sold schizo meds I'd use your pic on the packaging, but fade it away around the logo.

Every source I've found says that spinning and charged black holes have two event horizons in addition to the ergosphere
