You might also be interested in this (with much more): http://www.futuretimeline.net/

It's a nice concept, although I'd more interested if it were written by someone who knew what they were talking (enough not to be proposing things like which blatantly violate conversation of energy, i.e. "antimatter power plants"), and who didn't structure their predictions in the form of a narrative exposition of Malthusianism.

"10^{10^{26}} is 1 followed by 10^26 (100 septillion) zeroes. Although listed in years for convenience, the numbers beyond this point are so vast that they would be the same in whichever conventional units one could list them in, be they nanoseconds or star lifespans." All you people who've been saving your OMGs for something a bit more ridiculous than an inane celebrity reaction, now could be the time to use one...

If you want to go for big numbers, check out the Ackermann function. It quickly makes 10^10^26 hard to distinguish from nothing =)

Our entire perspective on existence is based on where we popped up on the cosmological timeline. If we'd come along earlier, we may not have been able to perceive the expansion of the universe, and the apparent disconnect between the hard limit of the speed of light, and the size of the universe. If we'd come along later, we may have figured that we were completely alone in a static sphere, with no observable matter…

What's really spooky is thinking about the things which we would have been able to observe if we had been around much earlier. Perhaps seeming constants have changed over the history of the universe, or other universes which drifted away from us along now-imperceptible dimensions. (I'm guessing you saw the same Brian Greene TED talk I did.)

I'll see your Ackermann function, and raise you TREE(3).

Plus one.

“You know, the most amazing thing happened to me tonight. I was coming here, on the way to the lecture, and I came in through the parking lot. And you won’t believe what happened. I saw a car with the license plate ARW 357. Can you imagine? Of all the millions of license plates in the state, what was the chance that I would see that particular one tonight? Amazing!” http://www.dyeager.org/blog/2008/04/probability-evo…

The quote is great, but I wish you had linked to some other article. That sums up as:

  You cannot predict the results of a shuffled deck of cards.
  Similarly, our current universe is impossibly improbable.
  Therefore, God did it.
It's a massive lack of understanding, whether it's right in the end or not.

Graham's number anyone?

Meh.

Take however many symbols it takes you to describe your large number. Call the symbol count N. Then my counterpoint is the Nth busy beaver number. That's a big number.
