\begin{abstract}
Hi, reddit! There are so many things we don't know about the Universe.
For example: What is most of the Universe made of? What is dark matter?
Where does dark energy come from? Why does the universe have a speed
limit? What (or who) is attacking earth with tiny, super-fast particles?
And for that matter\ldots{}what is matter? After generations of human
research, brilliant scientific minds, and crazy technological advances
we can confidently answer all of these questions the same way: we have
no idea. In our new book WE HAVE NO IDEA: A Guide to the Unknown
Universe we talk about why a vast portion of our universe (read: most of
it) is still a mystery, and what a lot of smart people are doing to
understand it. Ask us about physics, the universe -- known and unknown,
the Large Hadron Collider at CERN (Daniel works with it), illustration
(Jorge's the creator of PHD Comics), science in general, our deepest
hopes and fears -- in other words\ldots{}ask us anything! We will be
back at 4 pm ET (1 pm PT) to answer your questions.%
