Probably "is every simply connected closed 3-manifold homeomorphic to the 3-sphere S³?"

"- Scott, are you dead?"
"- Yes."
"- You liar!"

Wouldn't any question with an obvious answer work?

Is the sky blue?
Do you have 10 fingers?
Is your hair [insert hair color]?
Do you have two eyes?
Does the kernel of a homomorphism between two cyclic groups of the same order contain only one element?
etc.

Yeah, it's Poincaré. I like your last question too. And your new avatar, have you been to that place in person to take the photo or did you get it off of the internet?

You know guys, it's not a lie if he thinks it's true. Of course, this depends on your definition of the term. In my view, a lie is telling false information in order to deceive someone. What if the guy is blind and has never heard of the sky being blue? Ok, I'm just making life hard, of course obvious questions(such as the Poincaré conjecture) should satisfy this riddle.

1.scott could be colour blind
2. he might of lost a finger (dont know how)
3.he might be bald
4. 1 might nto work or be a glass eye
5.i have no idea what that means:D

This riddle isn't exactly clear...is Scott forced to lie or to try and find a way out of the question?

I think Zhylliolom was referring to Ricky.

lol he would of had to say no and also thanks Zhylliolom for liking my new avatar and riddle

Correction: Zhylliolom was talking to Ricky.

Anyway, I think this ("Does the kernel of a homomorphism between two cyclic groups of the same order contain only one element?") would work, but I'm unsure.

A thingy of a thingy of a thingy.

You'll study this when you're older.
