In the world of physics, there are always contests and
divisions of thought, factions of people supporting different theories of why
the universe is the way it is. Physics is divided into two different realms the
macroscopic (large) world for things like gravity and then the quantum world
(very small) where Quantum-chrono-dynamics (QCD) and Quantum gravity exist.
With string theory, devised by Michael Duff, Michael Green and Brian Green et
al, tried to unify these two worlds, the world of the macroscopic and quantum
world to create a “theory of everything”, which works as a self sustained and
self sustained mathematical model, which can allow for the description of the
12 fundamental forces and the different forms of matter.
String theory when first devised, was lead with some severe
controversy. Scientists would not touch the subject let alone research it, due
to the major consensus boycotting the research. People’s jobs and careers were
on the line, chancing such an endeavor. But in the last 10 years, Sting theory
has taken a big turn, making the topic much more serious and for respected
academics to start brain storming about it.

In the Universe scientists have discovered that it is made
up of two groups or very small important (Fundamental) particles, these are
called the boson and fermions. With bosons, that are carriers of the
fundamental forces, pertaining to, Strong/Weak nuclear forces, E.M Forces
(Electromagnetic) and Gravity(the weaker of the 4 forces). With fermions they are actually the matter
that you can see such as atoms, molecules in all its configurations.
The standard model, which has been herald as the most stable
and accurate scientific theory thought of, allowing for the explanation of the
forces except for the force of gravity. As mentioned in previous post the
inside of a black hole the mathematics breaks down in the singularity. This is
simply because the standard model cannot explain the math and physics behind
the mechanics of a singularities from a gravitational point of view. This also
applied to the big bang theory as well.
A word that some people might of heard from time to time,
and probably left them confused is the word super symmetry, this an important
part of string theory. This is need for the string theory to actually work,
where the concept that matter (particles) have a corresponding force.
More of will be covered in the next post. As this will a multiple post topic
