the-telescope-times: Trillions and Trillions As far as astronomers know, this universe of ours is nearly 14 billion years old and 93 billion light-years across. Only objects closer than between 10 to 12 billion light-years distant will ever be visible due to the expansion of the universe. Recently, a new survey upped the believed galactic population from around 100 billion to TWO TRILLION.
