Fascinating, that is an intriguing hypothesis. A temporal nexus is one very logical answer. However, I might propose a fissure in the nexus. This way the Malnosso would have acted as the high energy discharge that would have resulted in our temporary existence here.

[Spock thinks about this for a moment.]

It might be possible to format a phase discriminator.... this is a device that would cause a break in the nexus and allow for manipulation in subspace reality. Most curious...

[Spock seems a little lost in thought at the moment....]
