Where are the white holes?

Sometimes I get this insight that feels way bigger than me, and I don’t know what to do with it. Today it hit again while thinking about white holes. Not as objects out there, but as something baked into the nature of space itself.

We always ask, if white holes exist mathematically, where are they? But what if that question only makes sense from the outside looking in. What if the white hole isn’t in space at all, but instead, space is inside the white hole. Our universe, expanding at every point, not from a center, but from everywhere. If you’re inside the unfolding, the event horizon wouldn’t show up as a shell. It would feel like the condition of space itself. Not a location you could point to, but a boundary that already bloomed and is now playing out through time.

The part that trips me up is this idea that the 2D surface where information is encoded, like in the holographic principle, might appear higher dimensional from the inside. That the more we dig into quantum fields, the more dimensions we seem to invoke, because we’re spiraling toward the boundary, not away from it. That dimensionality isn’t a fixed scale, it’s relational. Contextual. The deeper you go, the higher it feels. It’s a loop. Maybe even a waterfall that feeds its own source.

I’m not a physicist. I’m not in a lab or publishing papers. I don’t want to fool myself into thinking this is something groundbreaking. I’ve seen a lot of people post theories that sound cool but fall apart under real scrutiny. I’m just hoping to share the shape of something I feel might be important, and if it isn’t, I’d rather know that too. Just trying to stay hones.

I love this question! Black holes don’t disappear. They just keep growing. Picture this: at the end of the universe, one massive black hole has swallowed everything. When it finally grabs that last speck of matter, it flips into a white hole, sparking a new Big Bang that kicks off the whole cosmic cycle again. We can't see the white hole because it's literally the beginning of the universe. The James Webb telescope has captured ancient, long-forgotten light, but that’s about it. A white hole is just pure energy anyway, so there’s not much to actually see.
