QUEST FOR SIMPLICITY
So close…
Gravity
Missing particles
…and yet, so far!
Too many

Cosmological questions
¿CCcómo conciliar gravitación y
mundo subatómico?
?
Dark Matter and Dark
energy?
?
Question about the beginning of the Universe
?
Why we have only matter in the
Universe? Where is the
antimatter?
Questions about the particles
How do they acquire
mass?
Why particles have
different masses?
?
William Ockham
“no hay que multiplicar los entes de la razón sin necesidad,
hay que ir siempre a las hipótesis más sencillas”
If this is the question…
New symmetries
Little Higgs
New particles
...
…this is the answer!
