Well, what I want to tell you here is
seeing if we can understand the composition of the Universe and to do so
we need to know the elemental particles that conform it and
also the interactions that exist between them.
So, what we are going to try to do, at the beginning of the talk, is describing
all the known particles and their reactions.
After that, we are going to do some expeculations
we are going to think that maybe we miss some particles in that list
we still do not know, but that could exist and taking these possible
particles, what we are going to try to do is associating those particles with
new asymetries, for instance super symmetry such as another one we have that is
called superstring, you have heared talking about it many times, and
we will also see that all those asyetries create new
particles. These are particles could be used to explain also
the problem with dark matter. We will also try to
talk a bit, since that is more or less the idea of this talk, trying to
understand the Universe and what we do not know and see how what we
do not know could be explained.
