# Top Ten Reasons Why Four Is a Better, More Significant Number Than Five

**I like five, but four is a more significant and more cool number. Sorry, keycha1n.**

### The Top Ten

*1*

**There are 4 dimensions in relativity equations**

*2*

**There are 4 confirmed fundamental interactions of physics**

Recent cosmology may prove the existence of a fifth, which I have been researching recently, but now I've made this list, part of me wants the dark energy to be driven by repulsive gravity and not quintessence. - **PositronWildhawk**

Would you be saddened if another fundamental interaction was discovered? More to research, more money for a physicist! - **keycha1n**

Unified theory, Kiteretsunu, treats the interactions as one equation, given that they can act as one on the smallest measurable levels, but macroscopically, their effects and properties are vastly different. Plus, we're not at a stage in which we can assume the standard model to be complete. Further development of it is now more than likely due to the recent Higgs discovery, which could potentially give the standard model the vacancy for new particles, possibly including a new gauge boson. - **PositronWildhawk**

*3*

**4 is the smallest composite number**

Hmm

This is why I always wear four on the baseball field. It's the best (and my favourite) number. - **PetSounds**

If it makes you guys feel better, I don't even know how to play baseball! - **keycha1n**

Cool. 5 is still better though. - **CityGuru**

*4*

**Space in 4 dimensions is the highest-dimensional space featuring more than three convex regular figures**

Okay, this is so true and there's no arguing with it. I'm having trouble on who to believe... - **RockFashionista**

Once you extend into the fifth, you get irregular polytopes. - **PositronWildhawk**

Can I eat that?

*5*

**4 is a divisible number**

Trying to share four cookies between two people? No problem. Trying to share five between two? You'll have to split a cookie! This is why imperial units matter. - **PositronWildhawk**

So is 12. A divisible number. 12 has more factors than 4. I added one item to my list which WILL TURN THE ARGUMENT IN MY FAVOUR. - **Animefan12**

Four cookies between 3 people? You'll have to REALLY split a cookie! - **keycha1n**

This, and that 4 is possibly my favourite number - **EvilAngel**

*6*

**There are 4 base types in DNA**

Uracil is in RNA, so does not count. - **PositronWildhawk**

*7*

**The number 4 is considered a death warning in Japanese culture**

I thought you LIKED Japan? Let alone, living! - **keycha1n**

That's Chinese culture not Japanese

*8*

**4 is the most infrequent digit in the known digits of pi**

Most of these items have something to do with math, science, or physics. But then again this is one of PositronWildhawk's lists after all. - **RiverClanRocks**

Oh, and the 4th character of the number Pi. Considering "3", "." and "1" then comes "4" - **keyson**

Well, the fifth number is 5: 3.1415! Isn't that much more satisfying? - **keycha1n**

Funny at the same time, it's the 3rd digit. - **keyson**

*9*

**The number 4 was used in ancient calendars for predicting lunar cycles**

We know approximate it to four weeks, but the measurements then were incredibly accurate without the technology we have today. - **PositronWildhawk**

*10*

**4 is the most common number on this list**

It can't be true! - **Ashes**

### The Contenders

*11*

**Atomic number of beryllium**

But 12 is the atomic number of Magnesium which is more reactive than Beryllium. So boo yeah - **Animefan12**

I don't know what boron is for, but I like it now. - **keycha1n**

Both boron and beryllium are highly underrated elements! But beryllium is better, because it has four protons. - **PositronWildhawk**

*12*

**4 is a Lucas Number**

*13*

**You can yell "four" at a golf course and scare everybody**

*14*

**4 dimensions in Schrodinger mechanics**

*15*

**4 is spelled with 4 letters**

*16*

**PositronWildhawk's 4th published list remained 4th most popular for a long time**

My fifth list, on the contrary, isn't such a big hit. But it was my third that got me sudden popularity, and that makes me proud of it. - **PositronWildhawk**

*17*

**5 is spelled with 4 letters**

*18*

**4 is cosmic**
