Electric monopoles exist in the form of particles that have a positive or negative electric charge, such as protons or electrons.
At first glance, magnetism seems somewhat analogous to electricity, as there exists a magnetic field with a direction defined as running from north to south..
Inflation solves the monopole problem because the particle horizon (which contains one monopole) becomes so big at the end of inflation that our observable universe contains too few monopoles to be detected..

In particle physics, a magnetic monopole is a hypothetical elementary particle that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa).
A magnetic monopole would have a net north or south "magnetic charge"..
The "monopole problem" refers to the cosmological implications of grand unification theories (GUT).
Since monopoles are generically produced in GUT during the cooling of the universe, and since they are expected to be quite massive, their existence threatens to overclose it [clarification needed]..
It becomes a problem in the hot Big Bang model, when one calculates the number of monopoles produced in events, such as the electroweak symmetry breaking.
One finds they would be the dominate matter in the universe.
This is contrary to the fact that no monopole has ever been observed, directly or indirectly, by humans..

A magnetic monopole is a particle with a charge system that has only one magnetic pole as opposed to the normal two, often called north and south poles.
The theory requires that they have a large charge and therefore a rapidly moving monopole would ionize atoms far more rapidly than electrons..
The Flatness Problem: Imagine living on the surface of a soccer ball (a 2-dimensional world).
It might be obvious to you that this surface was curved and that you were living in a closeduniverse.

While the Big Bang theory successfully explains the "blackbody spectrum" of the cosmic microwave background radiation and the origin of the light elements, it has three significant problems:.
1) The Flatness Problem: WMAP has determined the geometryof the universe to be nearly flat.
However, under Big Bang cosmology, curvature grows with time.

The Inflation Theory, developed by Alan Guth, Andrei Linde, Paul Steinhardt, and Andy Albrecht, offers solutions to these problems and several other open questions in cosmology.
It proposes a period of extremely rapid (exponential) expansion of the universe prior to the more gradual Big Bang expansion, during which time the energy density of the un.
