Blackholes are cool

If you could see a blackhole with a telescope you’d observe that it appeared more as though you were looking down a well or tunnel, rather than looking at a object in space. The black hole itself would appear as the “water” at the bottom of the well. Where the walls of the well were made of flattened space. Or very reflective walls of the well.

What would a flatlander observe looking into a cyclone from the surface? We are only looking at the surface level and we observer a 3d sphere.

If you zoomed into to the edge of the object, the edges would be red-shifted. Like looking at the horizon of earth just after a sunset from space. Or looking deep into the red spectrum edge of a prism diffusion.

Like a fish-eyed portal into a new universe. Like a well, wSome excellent pictures of black holes.

I find the doubled accretion disc concept super interesting and love the renderings of this. Even if there weren’t rings around the black hole, this helps explain how the space is shaped around this body.

But if you could look deep into the heart of a black hole, it would appear as if you were staring into infinity. It would appear as far away as the expanding horizon of our universe (Side note: The expanding edge of our universe and the event horizon of a black hole feel somehow connected.).

And if the universe wasn’t expanding…the heart of a black hole would appear further away than the very furthest object in the universe. As if you had a channel with no stars…forever…looking into the abyss. Truly a hole.

Like a lens focused out of infinity.

Or two mirrors staring at each other.
