“Let me first make two important assumptions, which I will discuss in more detail later on, but will now just say that they are both supported strongly by observational evidence: (1) that the laws of physics are the same everywhere in our universe, and (2) that space looks the same in all directions (the same density and distribution of galaxies).” — Jim Al-Khalili
