PREV>> 2.1.5 - Everyday Large Numbers for a Modern World
This article continues from the previous article, by continuing the trend into even larger numbers. These are Numbers that are rarely mentioned outside of tables of large figures cited in physics and astronomy ...

ONE SEXTILLION
1,000,000,000,000,000,000,000
10^21
At this point it's getting difficult to keep track of all of those zeroes. One sextillion is rarely heard of, and not well known, but it is officially recognized and the legitimate continuation after quintillion. One Sextillion is 1 followed by 21 zeroes ( 7 groups of 3 ).
The earth has a mass of about 5.98 Sextillion metric tons ( 1 Metric Ton = 1000 kilograms ).
There are about 6 sextillion cups of water in all the oceans of the world [1] .

The volume of the sphere approximating the Virgo Super Cluster ( The super cluster in which we reside ) is roughly 3.54 Vigintillion cubic kilometers [3] !!
ONE THOUSAND VIGINTILLION
10^66
A Thousand Vigintillion does not have a proper number name, there is no "illion name" for it. Scientists are perfectly comfortable using "scientific notation" and calling it simply "ten to the sixty sixth". The most common proposal for this number is naturally enough "unvigintillion", based on the trend established with decillion, undecillion, duodecillion, etc.
There are about a thousand vigintillion atoms in our galaxy [1] .
ONE MILLION VIGINTILLION
10^69
One million vigintillion is also known by number ethusiasts as "duovigintillion".
Note that by the time we reach numbers this big, it becomes very difficult to think of any example at all, not because numbers this big don't have physical representers, but simply because it is difficult to find an example that falls exactly in this range.
The Volume of the observable universe may be roughly a million vigintillion cubic miles [1] .
The Virgo Super cluster may contain close to 200 million vigintillion hydrogen atoms in it's 200 trillion stars [3] !!

One Trillion vigintillion, also called "quattuorvigintillion".
Unfortunately I was not able to come up with an example for this tremendous number, although there must certainly be a trillion vigintillion of something because this number is smaller than the lower bound for the number of sub-atomic particles in the observable universe. Let's just say that there is about a trillion vigintillion sub-atomic particles in 1/1000 of the volume of the observable universe.
ONE QUADRILLION VIGINTILLION

10^93
Also called "trigintillion", from the latin word "triginta" for 30.
ONE DECILLION VIGINTILLION
10^96
Because of the tremendous scale of these numbers, it is no longer practical to make jumps of a 1000 fold. Instead I will now be making jumps of a billion fold ! Because of this certain "illions" here will have no entries.
One decillion vigintillion is also called "untrigintillion".

A micrometer = 10^-6 meters. Microbes can be measured in micrometers.

Note: Recall that a Googol = 10^100 . This means that the volume of the universe is
4,700,000 googol cubic nanometers. The Googol is often regarded as impractically large, an not representative of anything in reality. However when we consider the entirety of the known universe divided by the some of the smallest known units of space, we easily exceed the googol. This proves that numbers as big as a "googol" are not as impratical and meaningless as once thought.

There is a theoretical "smallest unit of distance" that arrises in modern physics. It is the result of combining quantum mechanics with general relativity. In general relativity deals with the large scale features of our universe, while quantum mechanics deals with the small scale features.
In general relativity, gravity is reinterpreted as a force which distorts the fabric of space-time, and by doing so, effects the motion of neighboring objects. In otherwords, the theory says that the presense of matter distorts the local space-time.
In Quantum mechanics, what we can't observe is ultimately unknowable. It postulates that at the smallest scale the universe is random and chaotic, and is only governed by laws of statistics. As a by-product of this, it is said that on small scales, "virtual particle pairs" can spontanteously pop in and out of existence. Because these virtual particles are created and destroyed so rapidly, it is argued, that the conversation law of mass-energy is not broken. Another even weirder consequence of the theory is that as the scale gets smaller and smaller, more energy will pop in and out of existence in shorter time frames.
When we combine the 2 theories there is an interesting result. As we go down into smaller and smaller scales, eventually we encounter a scale where highly massive virtual pairs are created. Because of the huge amount of mass, general relativity says there will be a very huge local distruption in the space-time fabric. Eventually these distortions become so severe that the equations literally explode. This "bubbly space-time" is sometimes refered to as "quantum foam".
The result is that the continuity and consistency of space and time ceases to be meaningful. It is said that concepts such as "here" or "there", "past" and "future", get scrambled, so that there is no concept of sequence.
It is therefore impossible to measure distances smaller than this threshold. Hence, it becomes meaningful to talk of a "smallest possible distance that can be meaningfully measured". This minimum distance is called the "Planck Length", and it is approximately 10^-35 meters. So Now what if we take the entirety of the known universe and divide it by the smallest possible spatial unit ? ...
In this case we can say that the volume of the universe is 47 octodecillion vigintillion vigintillion cubic Plank lengths, that's 4.7 x 10^184 Pl^3 .
Note that this volume is computed by treating the universe as if it were the hyper-surface of a 4-dimensional sphere ( sometimes called the "glome" among the polychorists ). One can think of this "glome" as starting out as an infintesimal point at the big bang, and then expanding like a 4 dimensional balloon 4-space. In other words, this volume is only the volume of the universe 'now'. At an earlier time the volume would have been smaller, and in the far future it may be much larger still ! And notice the exponent, 184. Most people think numbers these large have no physical meaning, but what these estimates show is that they may very well represent tangable and measurable things !!
So that's it right ? We have reached the end of physical numbers ... not quite. Assuming the universe will continue to exist and expand the volume will increase with time. Cosmologists usually say the big bang occured somewhere around 15,000,000,000 years ago. What if we were to consider the universe a long long time from now ? ...
-----------------------------------------------------------------------------------------------
This page is now getting too large, so I will continue this discussion in a third part. Now we will consider the very limits of numbers that can have meaning in physics !!
