Universe that is missing. As in it is not there. Or at least if it is
there, we can't see it. We call this unseen stuff "dark matter". That
has been well known for sometime. What is trickier in answering is why?
Why is it that 95% of the universe is made up of this so-named "dark
matter?" An even trickier question is where? As in where is this dark
matter? It is those two questions that have plagued physicists for
decades. Dark matter, by its own definition cannot be seen, hence its
name. So how do we "see" it, how do we know "where" to look?
Physicists have been trying to think of various "indirect" ways to
"see" dark matter for decades. Now physicists at the Institute for
Advanced Study in Princeton, NJ and the Max Planck Institute for
Physics in Munich are ready to test their methods, The Economist reports...
