What is infinity minus one?

We all know that infinite means big. Really Big. But just how big before it becomes infinite? And how small must it become so it is no longer infinite? That’s when I came up with the idea “What is infinity minus one?”

Albert Einstein

To answer any question you must first look at the words. What is what does it actually mean? I found the definition below on the Internet.


The state or quality of being infinite.
“The infinity of space”
synonyms: endlessness, infinitude, infiniteness, boundlessness, limitlessness, unlimitedness, extensiveness, vastness, immensity; infinite distance
“She stared out into the infinity of space”

A number greater than any assignable quantity or countable number (symbol ∞).
“the transmission approaches 100% as the frequency tends to ∞-1

After reading the definition I just felt cheated. I realised that I couldn’t simply use ∞-1. What is infinity divided by two was also sounding like a paradox.

How the heck can I subtract one from a number if I don’t know what the number is?

∞-1 is Bonkers.

I decided that the best way to calculate ∞-1 is to start counting. At every point keep a record of what number you have reached. According to the definition at some point, it will become incalculable. Impossible to progress any further.

Therefore and again by definition, the last number that was documented must equal ∞-1

If you are a member of a discussion group most of them contain a smart arse. They are perfect targets for raising the subject of Siliconhell ∞-1 With a bit of luck they will begin counting and never bother you again. If you are the smart-arse we look forward to reviewing your scribbles.
