“A supernova?” Geary questioned, incredulous. “A supernova puts out as much energy in one blast as a star puts out over a ten billion year life span. An explosion like that would fry not only everything inside the entire star system it’s in but also surrounding star systems.”
“Yes,” Cresida agreed. “That’d be a negative outcome, obviously.”
“Obviously,” Geary agreed.
“But the other extreme says the energy in the matrix would, uh, fold in upon itself, like an infinite origami, getting ever smaller and tighter until it dropped into another state of existence and was lost to this universe. Energy output in this universe would be zero.”
Geary sat down, looking around and seeing the other knowledgeable commanders agreeing with Cresida again. “Then our two extremes are that the destruction of a gate would destroy an entire star system and adjacent star systems, or it’d do nothing at all. But what level of energy release is regarded as the most probable outcome?”
Cresida looked to her fellows as she spoke. “Most scientists believe the energy output would fall somewhere between less than that of a supernova and more than nothing, but no one’s been able to confidently predict how much that would be.”
“You’re kidding.”
“No, sir.”
“That’s the best science can offer? And those gates got built knowing they could potentially blow the hell out of this part of the galaxy?”
“Yes, sir.”
“They let you go really fast,” Commander Neeson noted.
Geary stared at the representation of the hypernet gate at Sancere, wondering just how many disasters traced their origin to the human desire to travel faster than before. I’ve been wondering if nonhuman intelligences might be tied somehow to this horribly destructive war we’ve been fighting for the last century. But I ought to know by now that humans don’t need nonhuman intelligences to influence us to do something stupid.
Hey. Wait a minute. “Why is it we don’t know more about this? We designed and built the hypernet system. How could we be so uncertain about important characteristics of it?”
Commander Cresida exchanged glances with her comrades again. “I can’t answer that exactly, Captain Geary. I know the practical breakthroughs that let us build the hypernet came ahead of the theories that explained it. A lot of the theory is still being worked out. That’s not the first time that sort of thing has happened. People often figure out how to do something before they understand why it works.”
“Us and the Syndics? We both made these practical breakthroughs at about the same time?”
She shrugged. “The Syndics stole the knowledge from us, sir. That’s what we assume, though I don’t have the security clearances to know for sure.”
Or we stole it from them. “The bottom line is, you’re telling me the Syndics won’t dare destroy that gate?”
“Uh, no, sir. We don’t know. They may have decided the risk is acceptable.”
Geary tried not to let his feelings show. We don’t know. What if the extreme guess is right, and this fleet causes the Syndics to do something that fries not only Sancere and this fleet but a lot of nearby star systems? And even just having this fleet appear at Sancere might cause the Syndic commanders to destroy the hypernet gate as soon as they spot us. But I can’t afford not to go to Sancere and attack. This fleet needs the supplies there.
There’s no alternative. I have to hope for the best, that the energy release won’t be so large it threatens anything, either nearby stars or just my ships.
Oh, hell. I know what they’ll do.
“We have to assume the Syndics will plan on waiting until our fleet is near the gate, then destroy it,” Geary announced. The other ship commanders stared at him. “They’re going to hope the gate releases enough energy to fry us but not enough to fry Sancere or anything beyond it.”
Cresida nodded in agreement. “And if it does fry Sancere, then that’s just collateral damage in their eyes.”
“But then what do we do?” Neeson asked. “We can’t just ignore the gate.”
“I’ll think of something,” Geary promised. I hope. “If this diversion plan works, we can keep the Syndics from having forces in place to actually blow the gate. Now, it sounds like we’re in agreement on the best course of action for Task Force Furious. Break from the formation, charge at the Syndic defenders, make a high-speed firing pass, look like you’re heading for something very valuable, but divert after the Syndics commit to an intercept.” He paused. “I’ll send orders what to do after that, based on the situation. The most critical thing is that I don’t want you to actually dive into the heart of the Syndic defenses all by yourselves. Get back out of there so I can employ you in conjunction with the rest of the fleet.” Everyone nodded. “I’ll ensure orders are sent to each of you. Thank you. Commander Cresida, please wait.”
After the virtual presences of the others vanished, Geary turned a serious face to Commander Cresida. “You’re going to be a good ways away from the fleet after you charge the Syndics. You could easily be more than a light-hour distant from the fleet. That means I won’t know if you get into trouble until an hour after the fact. I’m trusting you to fight smart, Commander. Keep the Syndics occupied, keep their attention on you, but don’t get yourself shot up. Can you retreat when it’s the best course of action?”
Cresida seemed to ponder the question for a moment, then nodded. “Yes, sir.”
“I want you alive and fighting, not proud and dead.”
She grinned. “Sir, you’ve demonstrated we can be proud, alive, and fighting. I’m still trying to figure out how you managed to bring everything together at Kaliban to smash the Syndics.”
Geary smiled back at her. “Do a great job at Sancere, and I’ll give you personal lessons on how to do it.”
“That’s a deal, sir.” They both stood, and Cresida rendered a precise salute. She’d obviously been practicing. Geary didn’t tell her that fleet salutes tended to be sloppier than that and as a result she looked more like a Marine. Come to think of it, maybe Colonel Carabali had been the one teaching her how to do it. Geary knew the Marines had been deriving considerable amusement from watching the sailors’ attempts to deal with Geary’s moves to reintroduce saluting to the fleet.
He sat down again after Cresida’s departure, gazing at the display, especially the representation of the hypernet gate. It hadn’t occurred to him before now that the gates were potentially dangerous. Potentially extremely dangerous.
Potentially by far the deadliest weapons mankind had ever built.
And he had no alternative but to charge most of his fleet right at the hypernet gate at Sancere.

The communications alert chimed urgently, bringing Geary to full wakefulness. He rolled and hit the accept-message control automatically, fearing to hear that some more of his ships had bolted the formation.
“Captain Geary.” Commander Cresida seemed both anxious and excited. “I’ve been doing some thinking. Odd concepts. But it occurred to me that since the hypernet gate matrices are suspended between so many tethers, maybe a matrix would respond somewhat like a net or sail, which means exactly how it collapses would depend upon exactly how the tethers release.”
Geary tried to get his mind around that. Fortunately, Cresida’s analogy wasn’t too complicated. “What does that mean for us?”
“Well, sir, if the way the matrix collapses affects the amount of energy released, which it should, and if the way the matrix collapses is dependent on how the tethers fail, then in theory it should be possible to use selective failure of the tethers to regulate the amount of energy released.”
