A lot is not enough

[hexafraction]

yes someone against all odds could get lucky.  but it would be , well...against all odds. 

I'm gonna have a go right now. I might be some time...

Best of luck, and share some with me! In all seriousness (and a lot of estimation), you're more likely to lose power AND have a heart attack AND be robbed AND be hit by a falling tree during your "lottery" session.

How many fucking grains on sand are on earth? And how you define " sand" ?

A terrorist attack during a plane crash while lightning shoots up my chuff will tell me that chance is smiling down upon me. When I crack them keys I'll sort you out, don't worry.

Cool concept...I was about to post that imgur reference before I saw that there is already a thread.

Whether this picture explain that the number is nearly unlimited?
Or can still be calculated?

The number can easily be calculated. Computers can represent numbers far more vast. They simply use positional notation, like we do, but in base 2. Representing this number should only take 161 bits, which is less than the length of this post.

The Alot is a fictional mammalian creature with brown fur invented by Allie Brosh, the creator of the webcomic Hyperbole and a Half. The creature was inspired by the common grammatical error writing the phrase “a lot” as “alot.” The Alot is often referenced when someone has made the error in a discussion thread to point out the mistake in a lighthearted manner.

It's ironic, but the OP actually did not make that mistake.

This is perfect for all those errors... Are there ones for those that are "defiantly confidant"?

It doesn't.  It gives an explanation of how big it is with a picture of a bitcoin symbol
drawn in the sand at a beach.

2^128, 2^160, or 2^256 are not "extremely large numbers" in the world of
large number mathematics.  But they are all big enough that collisions or
brute forcing are both unfeasible.

Our planet has approximately 7 billion people on it. Let's ignore the problems of population growth for the moment and assume we will always have 7 billion people.

Now let's also assume that starting this very second, all those people (our global population of seven billion) each begins to click the button to generate a new bitcoin address every second.

"WHY ARE YOU GENERATING SO MANY FUCKING ADDRESSES! You're going to cause a bitcoin address collision!" yells the supreme bitcoin chancellor of Earth. "STOP IT!" ಠ_ಠ

Let's pretend everyone's in on the joke, and they all ignore him.
( ͡° ͜ʖ ͡°)

With every human on Earth, all generating a new address every second it would still take about 6.5 billion years in order for there to be a 50/50 chance of a bitcoin address collision. For there to be approximately a 99% chance of a collision, the assholes would need to keep up this buffonery for about 11.7 billion years total.

2²⁵⁶ = 2^(10)(256/10)

10³= 1000 = 2¹⁰ (yeah I know 2¹⁰ is equal to 1024 but let's assume it's like that.

Then; 2²⁵⁶ = 10^256*3/10 = 10⁷⁷

78 digit number. It's more than that of course.

"then the total number of hydrogen atoms would be roughly 10⁸²" http://www.universetoday.com/36302/atoms-in-the-universe/

There's 1 private key for each hydrogen atom in the universe.

This kind of shit is very impressive but far too much for the likes of me to understand . After reading many of the comments in this thread I'll just be happy that it's clear there are untold amounts of bitcoin addresses & private keys to cope with mainstream adoption & a big future for bitcoin. The complex mathematics, facts & figures are too much for me, I'm gone

the math is quite simple.  mostly just multiplication.

You can tell by the reply titles (including this)

Apart from that, does anyone have any clue as to how many grains of sand there are on earth?

Reading this post was like eating a warm bowl of oatmeal on a cold winter morning.
Any post with the word buffonery in it warrants a thumbs up in my book...

I have often wondered about this topic in the past.
Thanks to all you math guys out there putting this into terms someone like me could easily understand.
I rest easy tonight knowing the odds of any of my addresses being reproduced are much more unlikely than me winning a silver medal in womens gymnastics. (FYI im a male)

Let me see if I understand
Ok so basically, there are about the same bitcoin addresses as we have stars in one Galaxy right?

Very thought provoking and nice picture by the way

Erm, thanks.....
So, let me take the first result: http://www.npr.org/sections/krulwich/2012/09/17/161096233/which-is-greater-the-number-of-sand-grains-on-earth-or-stars-in-the-sky

They said, if you assume a grain of sand has an average size and you calculate how many grains are in a teaspoon and then multiply by all the beaches and deserts in the world, the Earth has roughly (and we're speaking very roughly here) 7.5 x 1018 grains of sand, or seven quintillion, five hundred quadrillion grains.

Are we not forgetting that in the bottom of the sea there's sand as well?
What about those grains?

Anyways, my point was that there is no way we can know for certain how many grains of sand there is (or how many stars for that matter).
We can only guesstimate.

That being said, Bitcoin users have nothing to worry about when it comes to address collision.
