Astronomers have done an amazing job at mapping out this 'observiball', and over the past several decades cosmologists have assembled a very solid standard model of Big Bang cosmology that well and accurately describes the evolution of the Universe to the present day, from the time of the CMB and even somewhat earlier. The now fairly well-understood observiball is enormous. But it's almost certainly not everything that exists - its boundary just limits what we can see, not what is... Detecting cosmic bubble collisions would require some luck even if eternal inflation is true - collisions must be frequent enough, strong enough, and not erased by inflation within our bubble... And even if nothing is found, the very possibility reveals an amazing evolution of such enormous questions from rank speculation into the fold of solid scientific inquiry.
