The String Theory Paper

Decent Essays

The Standard Model is a theory that hypothesises what happened during the first instances of the universe after the big bang and how all of the matter in the universe was formed. It is currently a complete theory of what we observe in nature aside from incorporating gravity.

"In the course of the past few decades, the Standard Model has passed critical tests derived from experiment, but it does not address some profound questions about the nature of the Universe," (AFP, 2015)

This quote was taken directly from an article from ABC Science that discussed how the standard model is progressing. More importantly, theoretical flaws in the standard model that hinder it from becoming fact. Consequently, making it difficult for physicists to move …show more content…

String Theory is a Theory of Everything (ToE), it goes back to before the big bang and proposes a new theory as to how it occurred. The String theory states that we are a multiverse which means that there are 11 dimensions to our universe. It also suggests that the big bang was either two universes colliding or two universes separating. (Kaku, 2011) Moreover, String theory is a number of one dimensional strings that are close to the scale of Planck length and are 10-33 cm in length and float in space-time. Each string corresponds to each fundamental particle. (Elert, 2015) String Theory explains the interactions between the fundamental forces by fitting different types of mathematical models together. String Theory can only be predicted with super symmetry (Schwarz, 1997).

For gravity to be unified there must be a new set of particles and this is known as super symmetry. Super Symmetry is a theory that predicts that for each fundamental particle there is a corresponding partner particle. The names given to these new particles are squarks, sleptons, photinos, gravitinos, gluinos, winos and zinos. This means that string theory offers a way to incorporate the graviton which unifies gravity into the standard model with the corresponding super symmetric particle being the gravitinos. (Nave,
