How about a nice, easy riddle to play with this Saturday?  We’ve had a string of fairly hard riddles, and of course the Bonus Riddle was challenging.  Here’s a nice, comfortable riddle for you to kick around for a few minutes, so let’s get right to it:

This is an object.

It is not visible to the unaided eye.

This object was predicted mathematically years before it was actually discovered.

Although we don’t know too much about this object, what we know is strange.

We have hopes of knowing much more about it in a few years.

This object has companions.

It has recently been the center of controversy.

Some scientists believe it’s not what we have always thought it is.

This object is well represented in popular fiction.

There you go… now isn’t that easy?  I’m lurking, so come to the comment section and give it a shot.  We’re building a list of participants for the next bonus riddle, and we’d sure like to put you on the list.
