String Theory Explained

String Theory Explained

1. Atoms

   • We thought that atoms were the last layer of everything we know, this until when doing tests we could observe that when putting them together strongly elementary particles are created
     • The String Theory
       • What is that ?
         • String Theory promises to unify all the fundamental forces of the universe
           • This caused enormous excitement, and interest. String Theory quickly became graduated to a possible theory of everything
             • String Theory requires ten dimensions to function. So String Theorists did calculations on model universes and then they tried to get rid of the six extra dimensions to try to describe our own universe
               • The String Theory is very interesting,, but so far no one has been successful and no string theory prediction has been tested in an experiment.
   • Elementary Particles
     • These particles are produced thanks to the strong union of several atoms, the particles are so small that they are not visible to the naked eye.
       • ¿What to do to see them?
         • To be able to observe them we must occupy electromagnetic waves, this so that at the moment in which the wave travels, it collides with the particle and it emits a reflection which goes directly to our eyes.
           • But the probability that we can see it even if it is with light is very very very tiny, this since the particles are exaggeratedly small that the electromagnetic waves cannot collide with them, which causes the reflection not to be made.

2. What is the problem there ?

   • The problem is the Gravity
     • ¿WHY?
       • In quantum mechanics, all physical forces are carried by certain particles, but according to Einstein's General Theory of Relativity, Gravity is not a force like others in the universe.
         • Let's imagine it like this:
           • If the universe is a play, the particles are the actresses, but gravity is the stage.
             • To put it more simply
               • Gravity is a kind of theory of geometry, that of space-time, and of equal distances which must be measured with great precision, but since there is no way to accurately measure things in the quantum world, gravity does not work with history. of the quantum world
