Is it okay to ask a question that you already have the answer to?

Many times I've thought that there are a lot of questions that aren't being asked here on TED.
I'm talking about questions that are answered on say different Youtube channels that score viewings in the millions, questions that people in general obviously want answered but perhaps haven't thought of asking those questions.

Would it be right to ask those questions yourself in a conversation even though you've just learned the answer?

You could always post it as in idea or debate. But what if it's not an "idea" simply a very interesting and useful fact? And what if it's not debatable, how would you then post it?

I often Google stuff before asking a question on TED and after that I usually have no reason to post a conversation about it since I know. But the information isn't shared then, it's a problem I think.

Here are some questions that haven't been asked on TED that a lot of people find interesting.

These questions are from Michael Stevens Youtube channel "Vsauce", and his related Talk asks the fundamental question "How much does a video weigh?"

Why Do We Feel Nostalgia?
What if You Were Born in Space?
Why Do We Kiss?
How Much Money is There on Earth?
How Big Can a Person Get?
Is Your Red The Same as My Red?
Why Don't We Taxidermy Humans?
What Can You Do Without a Brain?
Why Do We Have Two Nostrils?
What If Everyone Jumped At Once?
What Color Is A Mirror?

Well the list can be made really long, and I just took some of the most popular videos from a single Youtube channel.

So, is it okay to ask a question if you know the answer, but you think that most people don't?
If so, how should that Conversation be structured? A question in the title and explanation in the explanation?

I'd love to hear your thoughts on the matter.

  • Jul 4 2013: could that be a rhetorical question?
    The definition in wikipedia could make it quite clear:
    A rhetorical question is a figure of speech in the form of a question that is asked in order to make a point.[1] The question is used as a rhetorical device, posed for the sake of encouraging its listener to consider a message or viewpoint. Though these are technically questions, they do not always require a question mark.
    For example, the question "Can't you do anything right?" is asked not to gain information about the ability of the person being spoken to, but rather to insinuate that the person always fails.
    While sometimes amusing and even humorous, rhetorical questions are rarely meant for pure, comedic effect. A carefully crafted question can, if delivered well, persuade an audience to believe in the position(s) of the speaker.[2]
    In simple terms, it is a question asked more to produce an effect than to summon an answer.
