So this was the spike in gamma radiation we saw a few months back, I take it. Some new kind of stargate, ostensibly to unknown regions of k-space?
It's possible, but I don't think so. There were two spikes in the event(s) you're referencing, possibly related to experiments being carried out at 'Ghost' research facilities - which ended up being the targets of the disastrous combined Empire raids that followed shortly after.
This is where things started to get interesting.
If we look at the chronicles from this time, they seem to be hinting that in an effort to improve the efficiencies of energy production at least some of the experimentation the ghost facilities were doing was using massive villard wheel-type devices in combination with 'blue boxes', the latter possibly there to tweak and up-scale the former's performance.
One researcher seemed to have found a way to generate massive energy output from a disproportionate input. Unfortunately, this resulted in him and most of his facility evaporating in the resulting explosion. His lover repeated the experiment, presumably with similar results - two explosions, two spikes.
For the last 5-6 months we've had access to the Ghost facilities. We've gathered the shattered villard wheels, research tools, etc. we've obtained BPs for implants that modify the efficiencies of ships allowing them to achieve greater warp speeds presumably for the same energy demands (EVE science =/= real science). And I believe it's the null sec pirate factions who have been most interested in buying the components of the ghost facilities back.
I think over coming expansions we'll start to see the development of research and blueprints that make use of the ghost facility drops that - until now - have just been vendor trash (albeit nicely paid for vendor trash). This will lead up to a mad rush by the null-sec alliances and power blocs to build the first of the stargates to new systems, possibly outside of New Eden.
More theories? The last time a new set of systems opened up we were introduced to the Sleepers, a new NPC faction. It's possible that this time we might see another alien entity emerge from whatever cluster is linked to. I'm hopeful that rather than it being blue-skinned bug eyed insect type aliens (or some Saturday afternoon sci-fi alien of the week variation) it's whatever has evolved over the last 20000+ years from the humanity left on the other side of the EVE Gate.
