Hello Everyone. This is my first post started on this site. Please, please, please excuse my ignorance but I couldn't seem to find the answer to my question online (although i'm sure it is). If the size of the know universe has a diameter of 93 billion lightyears with a radius in accordance to us being half of that, does that make it impossible for the light (suns/galaxies) of a great deal of the "observable universe" nonobservant? If this is true how do we observe what hasn't reached us yet? Thank you very much for reading and for any responses.
