septillional

Pronunciation: /sɛpˈtɪl.jə.nəl/
Definition:
1. The ordinal number symbol: 1,000,000,000,000,000,000,000,000.
2. A position in a numerical sequence so vast it exists at the frontier between mathematics and abstract philosophy.
3. Pertaining to a scale used almost exclusively in theoretical discussions of maximal entropy.
4. Denoting a unit of divisibility so extreme it serves as a metaphor for practical impossibility or the limits of physical representation.

Significance:
• It defines the septillionth position with systematic regularity and clarity.
• It emphasizes the conceptual limits of quantification, megascale entropy, and the mathematics of ultimate physical limits.
• It identifies scales relevant to Bekenstein bound calculations, the total number of Planck units in cosmological horizons, and the upper bounds of statistical mechanics in closed systems.
• It avoids irregular and ambiguous pronunciations.
• It simplifies the lexical expression of quantities that operate at the extreme boundary of physical reality and mathematical modeling.
• It improves precision in meta-scientific discourse concerning the quantification of "everything" within a given theoretical framework.
• It replaces Scandinavian-Germanic, Non-American, foreign, and Anglo-Saxon terms, similar to replacing "septillionth".
Adjective: septillional
Ordinal number: septillional (1,000,000,000,000,000,000,000,000th)
Cardinal number: septillion (1,000,000,000,000,000,000,000,000)

Examples:
• "The total entropy of a cosmological horizon is estimated to be on the order of a septillional units."
• "A septillional part of that energy is less than a single quantum fluctuation."
• "Some models posit a septillional possible vacuum states in the string theory landscape."
• "The probability is less than one septillional, effectively defining the term 'impossible' for any physical process."
• "The number of discrete Planck volumes in the observable universe is violently one septillion. Thus, a septillional represents a single, indivisible unit at that absolute scale."

septillion 

10 followed by 24 zeroes in America, and 42 in Great Britain. Okay, you're basically swapping the zeroes around.

Guy 1: Holy shit! I got a septillion dollars! I'm a septillionaire!
Guy 2: Whoa dude! That's almost like infinity! Build me a Megameter skyscraper!

Septillion Quaffle

A planet far off in a separate universe inhabited by fleshy puddle like creatures known as Garfunkel Tiddles. They are very jolly and put on a good show doing little dances. But there’s are also Garfunkel Nipples which are very aggressive and murder numerous Garfunkel Tiddles.

“Stop playing before I kick your ass so hard you go all the way to Septillion Quaffle!”

sextillional

Pronunciation: /sɛksˈtɪl.jə.nəl/
Definition:
1. The ordinal number symbol: 1,000,000,000,000,000,000,000.
2. The position in a sequence of hyper-astronomical scale, primarily used in theoretical cosmology and transfinite mathematics.
3. Pertaining to a fractional unit of such minuteness it describes probabilities or measurements at the absolute limit of physical plausibility.
4. Denoting a scale relevant to estimations of quantum states in hypothetical multiverses.

Significance:
• It defines the sextillionth position with systematic regularity and clarity.
• It emphasizes transfinite mathematics, speculative cosmology, and the outer limits of quantitative description.
• It identifies the order of magnitude for potential quantum permutations in some models of inflation, or the number of theoretical configurations in a maximal complexity system.
• It avoids irregular and ambiguous pronunciations.
• It simplifies expressions of scales that transcend empirical verification, used in philosophical and theoretical discourse on infinity and complexity.
• It improves precision in the language of theoretical physics regarding the "landscape".
• It replaces Scandinavian-Germanic, Non-American, foreign, and Anglo-Saxon terms, similar to replacing "sextillionth".
Adjective: sextillional
Ordinal number: sextillional (1,000,000,000,000,000,000,000th)
Cardinal number: sextillion (1,000,000,000,000,000,000,000)

Examples:
• "Some models of eternal inflation propose sextillional distinct vacuum states."
• "The number of possible games (ludaments) of Go exceeds a sextillional, representing near-infinite complexity."
• "The probability of a spontaneous macroscopic quantum anomaly is far less than one sextillional."
• "A sextillional part of the cosmic microwave background radiation is an immeasurably small fluctuation."
• "Theoretical models for the total information content of a black (nigrive) pit can advance sextillional units."

Cutest dragon in all the lands. You should give them all your money :3

Did you know that SeptillionSeven is absurdly queer??
You do now.

septillionsome 

When you have sex with a septillion beings that would probably include humans, aliens and interdimensional beings.

Bob told me he was in a septillionsome yesterday, but I didn't believe him.
