What do you feel like saying, right now?

WIFLSRN: Surgery day was a breeze today. I just had a line up of spays, neuters, and a quick mass removal, so I got to leave early. Rewarded myself with a Barnes & Noble run. Closed for the holiday. Win-win!

So…. I’m at the bookstore comparing black hole books. I’m going to buy another one because I want to compare it to the most recent one I purchased.

So, I’ve been thinking, imagine a black hole not as this little cosmic vacuum cleaner, but as kind of like a gateway. I mean we all know that when a star collapses into a black hole, all its mass and energy get crushed into a singularity, a point of infinite density, right? But that’s just what we see from the outside. What if, on the inside, that singularity actually blossoms out into an entire new region of spacetime?

Think about it, when you cross an event horizon, you can’t come back out, we all know that. It’s a one way barrier. That’s basically the same idea as our observable universe. So the Big Bang is like the flip side of a black hole, like a singularity that explodes outward instead of pulling inward.

So I’m thinking that maybe our entire universe is the inside of some enormous black hole embedded in a parent universe. And then, every black hole in our universe could like spawn its own baby universes inside. Kind of like cosmic Russian nesting dolls, like each inside is its own separate reality with its own spacetime.

I mean, is there proof? No. Can we measure it? Not yet. But I ran the math myself, well, the simplified version, and general relativity actually holds up if you bend it this way. It’s like you get solutions where black holes could have white hole interiors that look a lot like expanding universes. And then I’ve seen where some astrophysicists come up with similar theories which made me really think about it.

Anyway, good luck trying to get a telescope big enough to peek outside our cosmic bubble. I’ll stick to my coffee and trust the equations to keep me humble.
