What we have here is the visualization of a Reissner-Nordström-Wormhole which is intersecting two different universes (two asymptotically flat spacetimes).
The connecting tube is called the "Einstein-Rosen-Bridge" and only appears to be stable. In reality, a wormhole like this one collapses as soon as you pass the event horizon of one of the black holes and approach the central singularity, which is where the bridge begins.
Light follows geodesics. Geodesics on a cylinder are helical, or if the light beam's at right angles to cylinder's length, the geodesic's circular. A space ship traveling through the wormhole would see many images of themselves receding into infinity, something like being between two mirrors.
I always imagined a black hole as a really deep well in space-time in which all the matter it had sucked in got squished into a really small, really dense and massive ball. Like the earth... but ten million times heavier and more massive... and ten million times smaller xD''' I wanna go back to the simple physics I was learning in the sixth grade
btw... what would it look like if you saw a spaceship going into one of those things? *is curious*
... can you curve the top up and make me a glass for drinking?
