This basically reads like the kind of pseudoscience excuse comic book writers come up with to explain how all the heroes and villains in the book got powers. (Not least because that's actually where you go with it.)
There's a reason they don't write whole comics about the pseudoscience, though.
The matter itself is… ok, although you don't really do anything besides introducing it and pointing out how dangerous is could be. You also don't really do much with the people who can influence it, again, aside from introducing it and saying they could blow up earth.
Every SCP is a story disguised as a scientific report. The current story is, "There is this stuff and these people. Here are the laws by which it and they operate. They might blow up earth." That's the entire story.
There's just not enough going on here, and I honestly don't know where to tell you to go with it.
- Further developing the people who control it will be tricky, because superhero stories (even deconstructed ones) traditionally don't work well as SCPs.
- Delving deeper into the science is also risky because unless it gets really weird, scientific exposition gets boring without context or story, and you already have a lot of it. The fact that it has virtually no impact on normal human life doesn't help.
- There's always the story of what the Foundation does with the anomaly, how they research and contain it (and the humans involved), and what it leads them to discover. I don't know if there's enough room for improvement in that area to carry this thing.
No matter what direction(s) you choose, it needs more: Plot, action, interaction with people and things. Context and impact. Human stories. Whatever.
