Have you ever asked yourself, “What comes after a trillion?” With numbers becoming more significant in fields like economics, science, and even tech, understanding these huge figures is not just a mathematical curiosity, but a practical necessity. Once you’ve wrapped your head around a trillion (1,000,000,000,000), you might wonder what comes next and how we name these enormous numbers. Let’s explore the practical applications of these large numbers.
In this blog, we’re going to take a fun and fascinating journey into the world of large numbers, from the quadrillion to even mind-boggling figures like a googolplex! So, let’s dive in and discover what comes after a trillion.
What number Comes After Trillion?
The number that follows a trillion is a quadrillion, which is a 1 followed by 15 zeros. Written out, it looks like this: 1,000,000,000,000,000. Beyond quadrillion, we continue adding sets of three zeros to the number, each with its unique name:
- Trillion = 1,000,000,000,000 (10^12)
- Quadrillion = 1,000,000,000,000,000 (10^15)
- Quintillion = 1,000,000,000,000,000,000 (10^18)
Between trillion and quadrillion, there are numbers like two trillion and five hundred trillion, but they only get a new name once we add another three zeros and reach quadrillion. This naming pattern is regular and predictable, continuing as the power of 10 increases by three for each new “illion.” This regularity should give you confidence in understanding these large numbers.
Names of Large Numbers: From Million to Googolplex
Beyond trillion and quadrillion, there’s a whole series of big numbers. Here’s a list of some of the most significant numbers, including some that go far beyond what we encounter in daily life:
What Is a Googol and a Googolplex?
You’ve probably heard of Googol before—no, not the search engine! A googol is a considerable number: a 1 followed by 100 zeros. While there isn’t much practical use for it in everyday math, it’s an impressive concept that helps to highlight just how vast the world of numbers is.
But wait—there’s more! A Googolplex is even more astounding. It’s a 1 followed by a googol of zeros, making it so large that even if we used all the atoms in the universe as a writing tool, we still wouldn’t have enough space to write it out.
Fun Facts About Large Numbers
- Centillion: A centillion is a 1 followed by 303 zeros. This number is far beyond what we typically encounter in any practical use, but it has its place in the naming structure of large numbers.
- Skewes’ Number: A famous mathematician, Stanley Skewes, introduced Skewes’ number, which is 10^(10^10). It was the largest number ever used in a mathematical proof when it was first discovered in 1933.
- Graham’s Number: This number is so large that conventional mathematical notation can’t express it. It’s widely regarded as the largest number ever used in a mathematical proof, far beyond human comprehension.
How to Understand Extremely Large Numbers
It’s easy to get lost when dealing with large numbers. How do you visualize something like a quadrillion or googol? Here are a few comparisons that can help:
Counting to a Trillion: If you tried counting up to a trillion one number at a time, it would take you around 31,709 years to reach that number!
Googol: If you wrote out a googol by hand, it would take you an extremely long time since it’s a 1 with 100 zeros after it.
Googolplex: Writing out a googolplex, a number so enormous that there isn’t enough paper in the world to do so, boggles the mind. To put it simply, it’s bigger than you can imagine.
Real-World Applications of Large Numbers
You might think such large numbers are purely theoretical, but they actually come into play in the real world:
Economics: National debts are often expressed in trillions, and global economies deal with quadrillions of dollars in assets.
Astronomy: When astronomers talk about the number of stars or galaxies, they often use numbers like sextillion or septillion.
Data: As the digital world expands, we measure data storage in petabytes (10^15 bytes) and even exabytes (10^18 bytes).
Beyond the Trillion: A Growing Numerical Universe
With the advancement of technology and science, large numbers are becoming more relevant than ever before. As data grows, space exploration continues, and new discoveries are made, we’ll likely need even bigger numbers to quantify the information around us.
Conclusion
So, what comes after trillion? The answer is quadrillion, followed by quintillion, sextillion, and many more. While these numbers might seem distant from everyday life, they serve as a reminder of just how vast and complex our universe—and even our own world—can be.
From national debts to the number of stars in the universe, large numbers help us make sense of everything on a grand scale. Who knows? In the future, you might work with some of these enormous values.
