good job i was looking around for hard ones.

I am served at a tableIn gatherings of two or four. Served small white and round. You'll love someAnd that's part of the fun. What am I

Table Tennis

Anyways, new riddle:

A group of people with assorted eye colors live on an island. They are all perfect logicians -- if a conclusion can be logically deduced, they will do it instantly. No one knows the color of their eyes. Every night at midnight, a ferry stops at the island. Any islanders who have figured out the color of their own eyes then leave the island, and the rest stay. Everyone can see everyone else at all times and keeps a count of the number of people they see with each eye color (excluding themselves), but they cannot otherwise communicate. Everyone on the island knows all the rules in this paragraph.

On this island there are 100 blue-eyed people, 100 brown-eyed people, and the Guru (she happens to have green eyes). So any given blue-eyed person can see 100 people with brown eyes and 99 people with blue eyes (and one with green), but that does not tell him his own eye color; as far as he knows the totals could be 101 brown and 99 blue. Or 100 brown, 99 blue, and he could have red eyes.

The Guru is allowed to speak once (let's say at noon), on one day in all their endless years on the island. Standing before the islanders, she says the following:

"I can see someone who has blue eyes."

Who leaves the island, and on what night?

Is her bday Dec 31st and it's New Years day when she tells you this? Because that would make her 8 now, and next December 31st she'll be 9, but it's still the same year as this New Years Day. Then next year on New Years Day she'll be 10.

I'm telling you, if I think long enough I can usually get em.

Indeed, nicely done

dark matter, she was 7 went into space for 2 yeas but reversed how travel normally works and only was gone for 2 days.

Lol, that's an interesting take on it And actually, with a bit of reworking, it could work. If the little girl was staying on earth and you travelled in a space ship at relativistic speed, then time would pass more slowly for you relative to the earth. So when you returned after a year, more time would have passed on the earth. Provided the young girl knew the speed you'd been travelling at (and had a crazy knowledge of relativity for a 7 year old) she could have calculated the relative times you would both experience.

However, there's a more mundane example that doesn't require accelerating you to significant fractions of the speed of light

Ok puffy...didn't mean to interrupt your physics class with my poor math problem. It is meant to be played out as I explained it, not some math problem to be solved for a grade...take it easy

Sorry, didn't mean to come across all prissy Was just trying to answer the riddle, and the answer really is that the question is wrong It's a neat little bit of narrative that tends to throw people for a loop initially.

Which I would imagine would take even more time.

Not at all, would probably take about 15 minutes to knock together a script to do just that. Just ban the IP

I'm 19 and I honestly feel like more of an adult than most people I know who have already graduated college and gotten careers.

ROFL! Make sure to save that and read it again in a few years
