How Far Out There is Out There?

Have you ever wondered how far away is the farthest visible galaxy?  Or what is the heaviest balck hole so far observed>  How about what is the fastest orbital speed of an object revolving around another stellar object?

Being a life-long nerd I enjoy nothing better than to see the latest high-end astrophotography and reading the highest exponential distances, masses and speeds tacked onto these images.

Well Astronomy Magazine has an article called “The most extreme celestial objects in the universe.” that answers some of those questions with lots of beautiful and intriguing astro-photos and other visuals.

Well, sometimes we have to step back from politics and smell the roses or gawk at the latest eye-candy taken by the James Webb Space Telescope (JWST).  After all this is Orion’s Cold Fire.

I’d imagine that if you are orbiting just outside the event horizon of a black hole, the orbital velocity would have to be close to the speed of light.

The cool thing about galactic (or larger) black holes is that the event horizon may be far enough out that it may be possible to enter the hole without tidal forces tearing you into individual atoms.

No telling what’s inside, we may be inside one.
