The more DISCO S3 plays out, and the more I think about it, I think the Sphere Builders from Enterprise are behind The Burn. They have a demonstrated ability even in the 22nd century to affect massive areas of space and change its fundamental properties. 1,000 years later? Who knows what they might be capable of if they’re still pissed about multiple invasion attempts failing?

I have little evidence other than motive and the potential scaling of known tech they have. The Sphere from S2 felt oddly like them, though it appears oddly benevolent. Perhaps it was from before their politics took a turn for the worse? Or it was just an information gathering device rather than a weapon in itself?

Maybe this weeks episode will shed some light on things.
