Do you believe in the 8th degree theory of the world?

Not sure what it's called exactly..but something along the lines of, you can connect everyone in this world through 8 (?) relations. Like I know someone who knows someone who knows someone etc..and through 8 connections I can connect it to anyone in this world. I totally didn't believe it when I heard it at first, but I suppose it's possible.. but there has to be some very secluded people who only meet a handful of people in their whole lives that that can't cover right?

I've talked to customers and gamers from all over the world, but do I 'know' them? Not really, unless vague contact once means knowing.
In which case, does it have to be 2 ways, or is seeing someone on a picture or on TV once enough to know them?

It seems believable. I did some calculations.....

Assuming there are 6 billion people in the world.
Assume that I know 50 people by a first-name, last-name basis.
And my 50 people know 50 more people, and therefore, through a 2nd degree, I know 50^2 or 2,500 people.
Suppose those 2,500 people know 50 people, so therefore, I know 50^3 people....and so on and so forth.

50^6 = 15,625,000,000, or 15 billion people.

In actuality, the average person would only need to know ~42.6 different people for it to work out. HOWEVER this does not factor in duplicates; therefore, you must know 42.6 unique people, and each of those 46 people must know 42.6 unique people each.

As an afternote, if it was EIGHT degrees of seperation, each person would only need to know ~16 .7 unique people.

Kinda cool how the exponential propgates through 6 billion relatively fast, eh?

Interesting point there - I work at Walmart. I..."encouter" a lot of people; most of them just get in the way when I'm hauling along a pallet of over 1000 pounds of freight (yes, I've calculated it; some pallets are under 500 pounds, a few are over 1500 pounds). Stuff that heavy doesn't stop on command. Not run over anyone yet.
But anyway, if every customer I help out counts as knowing, then it may be possible. I wonder though, how was the number 8 chosen? Why not maybe 15, just to be sure? Not to be repetitious, but how well must you really KNOW someone for it to count? :)

Uhh .. ok. So what's the answer to the question?

hey, i just always wanted to call someone on a tech forum a dork...Kinda like the pot calling the kettle black...I guess the humor is lost....

To answer...No. Its people IRL.

It just plays on a principle of mathematics...

Say the average person knows 1000 people.. and we assume that the people that person knows each know 1000 different people..

When you have 6 degrees of separation, you have 1000^6 that are within 6 degrees of you. Okay, so that's 1000000000000000000000 people that you are 6 degrees from.

Considering there's only about 5 billion people in the world (5000000000), shouldn't the possibility of knowing 1000000000000000000000 people, even if some or many are overlapping, cover everyone in the world?

That means there's 200000000 possible people within the 6 degrees for each person in existence... so there's plenty of room for overlapping.


Who knows? Maybe someone I know know's someone that knows someone that knows someone that knows someone that knows someone that knows Kevin Bacon.

The problem with this is that it doesn't consider the many isolated groups of people in the world or the hermits that never end up knowing anyone other than their self.

I have heard of this. They conducted a test where the idea was to deliver a letter to the opposite side of the globe. Idea was that the first person gives the letter to someone who might know someone from that area, the second person does the same etc. etc., untill the letter reaches it's destination.

The test I read about was to deliver a letter from US midwest to someone in UK. The first person gave the letter to a priest in his local church who had family-members in UK. The priest sent the letter to UK to one of his relatives, who knew people closer to the recipient of the letter and so forth. If I remember correctly, there was 6 people between the first person and the resipient of the letter.
