The Professor Zoom Time Remnant predicament isn't as difficult as it originally was.

Eddie Thawne's sacrifice erases Eobard from existence causing a Grandfather Paradox.

Original: Nora Allen is never killed > Barry becomes The Flash > Eobard Thawne is born > Birth of Professor Zoom.

Alternate: Battle of 2024 > Death of Nora Allen > Particle Accelerator Explosion/Birth of The Flash > Eddie Thawne sacrifices himself.

Singularity.

Because the Original and Alternate timelines are in an infinite loop because of Eddie's sacrifice there's no way the timeline can fix them hence the Singularity. However due to The Flash and Firestorm the current timeline has been you could say reconstructed so events such as Nora Allen's death have now become fixed points in order to keep this new timeline intact. Since Eddie and his descendants aren't connected to the Speed Force it doesn't protect their family history from being erased from existence. The only thing the Speed Force has preserved is Eobard's younger self to preserve events of the timeline in order to keep it intact. 2016 is when he finds out what time period Barry is from, 2024 is the battle from the Newspaper article, and 2000 is Nora Allen's death.

It's Time Remnants that are created that puzzle me more than anything. Eobard's Time Remnant is to preserve the timeline. Zoom's Time Remnant was a version of himself from his past which he created (presumably before he got hit by the Particle Accelerator during electroshock therapy which is why Team Flash couldn't detect a Speed Force connection, but he had learnt how to use Speedster skills such as Phasing via Velocity Drugs, and why he became terminally ill). However created Time Remnants act separately to their original self, such as Zolomon's Time Remnant falling in love with Caitlin, and he was becoming completely different person leaving his life as a serial killer behind. I understand the death of the Time Remnant having no effect on the original because the protection of the Speed Force shields the Speedster from the death of their past self. The only question I've had on my mind about all this is do the Time Remnants share memories and emotions with the original counterpart because it seemed a bit odd that after Zoom killed his Time Remnant he had the feelings that the Time Remnant had for Caitlin.
