Semiexistence

Semiexistence is a FES rank between nonexistence and existence, which is the strongest one in our Cetaverse. It is the only FES rank that can't be found in verses beyond Omniverses.

Property
Most interactions with existence also work properly for semiexistence, but however, couldn't interact hyperatoms beyond biradioactivity. Finding differences between existence and semiexistence is 99.99% impossible, except for biradioactivity hyperatoms, which only 50% of elements can interact semiexistence.

The 50% Semiexistential Law
The 50% Semiexistential Law says that for all forces in a Cetaverse, 50% of them can't properly interact semiexistent objects. For example, a Multiverse should have equal amount of forces that can interact it, and forces that can't interact it.

Studies currently show that there is a 99% chance that the law is correctly interpreted for scales between Universes and Cetaverses. Therefore, there is a noticeable problem on universal-scale, and should be researched further for resolving it.

Describability
Like existence, semiexistence is limited to non-abstract objects. Therefore, it can be easily described by us.

Amount
In our Barrelplex, the amount of semiexistent objects is at least $$\omega*10 \uparrow\uparrow 100$$, due to being isolated in Omniverses, and also Barrels. However, it is really hard to determine the estimated amount for our Cetaverse, because all Barrels are inequally separated over 2 Cetaverses.

Synthesis
Due to being a FES rank, a Protospatial particle for this rank is absolutely impossible. However, it could be synthesized by equal amounts of Protoverses and Nullirotos.

Trying to synthesize with unequal amounts would result in chaotic situations, even destroying Boxes. Fortunately, Semiexistence is a really common one compared to other FES ranks.

Nonexistence (Existence-0)
Semiexistence would be entirely nonexistent, if trying to interact with it. Unfortunately, all semiexistent objects are only located in normal Omniverses (mostly existent), and isolated in all Barrels, due to a really high presence of nonexistence in the Outside.

Negaexistence (Existence-(-1))
Negahiggs can barely interact semiexistence to make more negaexistent objects, but semiexistent entities couldn't spawn negaexistent objects by imagining, which causes a problem why Negahiggs is significantly more powerful than imaginations.

The 50% Semiexistential Law is correctly interpreted for all existence-(-0.5) objects (semi-negaexistence). But existence-(-1.5) really doesn't exist, because a existence rank between existence-(-2) and negaexistence always turns into one of those both ends, due to Acic Fields. This anomaly is called Acic Law.

Superexistence (Existence-2)
Semiexistence can properly interact superexistence, without a single anomaly.

There is also a FES rank called semi-superexistence, in which it goes between existence and superexistence, making it existence-1.5. The 50% Semiexistential Law is correctly interpreted for all interactions with semi-superexistence.

Metaboxial structures
We don't know that megaboxial hyperatoms could interact semiexistence, and by the study from most researches, there shouldn't be.
