observable universe 

The universe is, give or take, around 13.8 billion years old, and therefore the furthest objects we can see are 13.7 billion light years away. However the universe is forever expanding and therefore by the time we see the object, it has already moved billions of light years away, making the sphere of the observable universe (technically) larger than 13.7 billion light years in radius. The actual size of the observable universe is closer to 46.6 billion light years in radius, due to all the expansion and contains over 2 trillion galaxies. Everywhere in the universe has a point such as this, as our universe is theoretically infinite.

The observable universe contain all that we can know of about the cosmos at this very moment. Despite all we know, however, life itself, sentient or otherwise, has only been confirmed to exist on Sol III, otherwise known as good old planet Earth!

obserbation

The kind of masturbatory or self-tickling non-questions one hears, more often than not, at academic panel discussions, disclaimed before or after by some form of the phrase "not really a question, I guess."

Whispered to an ally, loud enough for strangers in within a three-chair radius to hear, "Nice obserbation. I can't believe that guy's tenure-track and I'm not."
