*Dark Matter: the greatest puzzle of our time?*
Nobel physics committee secretary in Dublin
Public talk, Wednesday, December 4, 2013
Amazingly, we don’t know what 95% of the Universe is made of – just 5%
of the mass in the Universe is made of standard 'stuff', composed of
familiar particles such as protons and electrons. The rest is what
scientists call “dark matter” and “dark energy”, and this is one of the
great puzzles of our time. Now, people can hear the latest on the
search for dark matter in a public talk [Wednesday, December 4th, 2013],
when an international expert visits Dublin.
Evidence for dark matter includes a stunning photograph of two massive
galaxies colliding at astonishing speeds, taken by the Hubble Space
Telescope and Nasa’s Chandra X-Ray Observatory [see image link below].
This is one way scientists can search for the dark matter that they
think makes up about 20% of the mass of the Universe.
Tantalising evidence also comes from a detector mounted on the
International Space Station. The Alpha Magnetic Spectrometer is peering
into deep space, looking for dark matter in the debris from cosmic
collisions – much like the Large Hadron Collider at CERN found the Higgs
Boson in the fallout from particle collisions.
But the latest news from that experiment, announced just a couple of
weeks ago in mid-November, suggests that so far scientists have only
seen standard everyday matter and, so far, no dark matter.
So it is timely that one of dark matter's leading experts visits Dublin
next week to give the 2013 public lecture for the Dublin Institute for
Advanced Studies school of Cosmic Physics. Professor Lars Bergström is
Professor of theoretical physics at Stockholm University, and secretary
to the Nobel physics committee. His talk, entitled: Solving the Puzzle
of Dark Matter?, is open to all and admission is free.

*About DIAS: *the Dublin Institute for Advanced Studies is Ireland’s
premier independent research institute. Founded in 1940, DIAS has
Schools of Cosmic Physics, Theoretical Physics, and Celtic Studies, and
is well known for its popular Dunsink Observatory open nights. Every
year, each DIAS school hosts a major public lecture, known as the
“statutory lectures”. For more information see:
