When research started into fuels suitable for internal combustion engines a peculiar new phenomenon was discovered. Researchers noticed that when engines were being run at certain RPM (revolutions per minute) the engine would suddenly fail, often in spectacular and unpredictable ways. This came to be referred to as Critical Instability.

Energy release and the aether[edit | edit source]

Normally it is not possible to manipulate the aether mechanically, but as with almost everything there is an exception and in this case it's Critical Instability. What happens is that when energy is released through a chemical reaction it has a nigh on immeasurable effect on the surrounding aether. The effect is so small that even at extremely high levels of energy released (like when detonating an atomic bomb) the effect on the aether is still negligible.

Resonance[edit | edit source]

One single instance of energy released through a chemical reaction does not have any real effect on the aether. However, the same does not apply to the same reaction occuring intermittently at a high rate for a period of time. The repeated reaction and release of energy can under some circumstances cause resonance in the ather, leading to the effect on the aether becoming increasingly more noticable. Once the aether has started to resonate it very quickly spirals out of control and in effect the aether channels and weaves itself.

The frequencies during which the aether will resonate like this are highly dependent on the substances involved in the chemical reaction. Scientists and researchers are talking about Criticial Instability Frequency (CIF) as a material property. As a matter of tradition CIF is usually measured in RPM rather then Herz. This is a nod to how the property was discovered and where it still matters most - the research of fuel for internal combustion engines.

Effects[edit | edit source]

The basic effect of critical instability is that when the aether resonates at a high enough frequency for long enough it will start to channel and weave itself. This self weaving has so far proven to be very unpredictable and completely uncontrolable. The only thing that can be taken for granted is that the effect will halt the process that generates the energy release, effectively preventing the aether from further spontaneous channeling and weaving.

Anecdotal evidence also has that the more expensive the equipment involved is, the more violent and destructive the consequence of reaching critical instability will be. This has not been proven conclusively, but it adheres to Murhpy's Law.

Implications[edit | edit source]

That critical instability is a significant issue when researching fuels for internal combustion engines has already been noted. However, critical instability needs to be considered under other circumstances as well. While less significant it is still very much an issue for automatic weapons. In the case of firearms it is easier to adapat though. The rate of fire is often constant and the number of shots that can be fired before needing to reload is limited.

A less obvious area where critical resonance may be a factor is high speed data communication. It is not yet conclusively proven, but there are several hints that critical instability may be a limiting factor when it comes to sending data packets.

Real world consequences[edit | edit source]

The discovery of the Critical Instability Frequency lead to some significant changes into how research is done. Specifically the safety procedures for testing of fuels were reworked from the ground up. The short term costs are higher and the testing of new fuel types takes longer. In the long run the additional costs pay off though. Researchers produce better results when they don't fear for their lives and investors are happier when research facilities aren't expected to blow up as often.

Weaponry[edit | edit source]

There has been some research into the use of critical instability in weaponry. Due to how unpredictable the reactions are no significant progress has been made - at least none that is publicly known.

Examples of reactions[edit | edit source]

Above is explained about what Critical Instability is and how it works. There are few examples of what the actual reactions referred to are though. While unpredictable, they are almost always destructive and violent. Below is a list of a number of different things that have happened to engines used for testing of fuels.

  • Explosion. Very Common. The explosions vary in power from just destroying the test engine (most common) to destroying the entire test site (rare).
  • Heat. Very Common. The reaction emits heat enough for the test engine to melt.
  • Implosion. Common. The reaction creates a powerful vacuum that warps and shrinks the test engine and occasionally the surrounding area.
  • Freeze. Uncommon. The opposite of Heat. All heat is removed from the area and the test engine freezes.
  • Fire. Uncommon. The test engine and the surrounding area catchest fire. This is different from Heat in that the engine burns rather than melts, despite the heat. This process is not well understood.
  • Evaporation. Uncommon. The test engine or parts of the test engine evaportates.
  • Material transformation. Uncommon. The material that the test engine is made up of changes into something else, usually another type of metal.
  • Teleportation. Very uncommon. The test engine or part of it are teleported to a different location, usually within sight. On a few occasions engines have disappeared completely only to be found months or years later in other parts of the world.
  • Putrification. Extremely uncommon. The engine rots.
