@ Scream: A "singularity" is a singularity, whether it is in the real world or in fiction, they're one and the same, a region so dense that it's gravitational pull is (to all extents) ifinite. A region where the very concept of "time" no longer exists because "time" is infinitely long.
A "black hole" is a "clothed singularity" in that the infinitely dense point is "hidden" from the rest of the universe by an "outer event horizon" (for want of a better analogy, a whirlpool). (All black holes rotate).
A "naked singularity" is an infinitely dense point that is not hidden. Usually because due to the laws of physics, the "black hole" (or whirlpool) has evaporated away. Microscopic sized black holes would (in theory) take billions of years for their whirpool to "evaporate", so one can imagine how long it would take a black hole that was once a star, to evaporate, (almost infinitely long).
In our universe, scientists/astronomers/physicists have only known of one "naked singularity" and that was the one that coughed out our entire universe.
A wormhole is similar to a black hole, except that it would in theory allow 2 way travel. Go in one end, and come out somewhere completely different. However, the gravity around the exit (and entrance) would be so extreme that any wormhole should in practice collapse in on itself and form a black hole instead of a wormhole.
Furthermore, in the episode, time is NOT collapsing in on itself. There is even a precedent in the tv show for this to NOT be the case.
Cisco !!
He STILL remembers the events in the timeline that Barry changed. By all rights, if the RF has been erased, or that timeline erased, Cisco shouldn't have those memories. BUT, he DOES have them. This means that THAT timeline STILL exists and is merrily going along its path.
Time is therefore not collapsing in on itself, the wormhole/singularity/black hole/ is merely the end product of Eobard's plan/experiment. All is "working as intended".
