the past centuries. Theoretical and observational advances in astronomy, physics and cosmology have taught us an incredible amount. But the universe contains a great deal that we have never seen and likely never will. Various factors account for our limited vision. Many objects are simply too distant to observe. Something very far away won't necessarily amid or scatter enough light to be identified, since any light it did send out would become too widely dispersed and dim. On top of that, dust or celestial bodies might block our line of sight or obscure our view. Those space probes in distant regions of the cosmos do help surmount these obstacles. No probe has made it to the nearest star. Never mind the nearest galaxy, with their restricted reach and only imperfecta resolution. Direct probes provide Onley limited access at best.
