Personally, I think the most fascinating part of seeing an image like this is that we are literally looking back into time and those galaxies are probably not even there anymore; Swallowed up by black hole(s) or destroyed through collisions with other galaxies long ago. Yet, the photons physically emitted from their stars from a time of the Universe's infancy, have finally made their way to our neck of the woods.
Yeah, fuck knowledge right? Are you putting me down because you lack the most basic tools for understanding how this universe works at the most elementary level and are thus projecting your own insecurities on me, or do you think you will somehow make someone worth a damn laugh at your totally unfunny gif?
pretty sure that given the size of the universe being the only life is statistically impossible.
I wouldn't even rule out more life in this solar system .. yet. Maybe certain moons, mars ...
Caltech recently published estimates that put the number of planets in the Milky Way alone, to be in the range of 100-400 billion. I read somewhere recently that said they now think most planets are rocky and earth-like as well and not gas giants. Combine that with the number of icy moons of Saturn and Jupiter (Europa, Enceladus, Gannymeade, etc.) who have liquid water oceans underneath miles of ice, so there is most certainly a propensity for our own solar system to harbor life. People who think life only exists on Earth are idiots.
