  • Just short of 6 trillion miles and we "know" about a little more every single day because new light reaches our telescopes every day.

    That's a picture of one little section the universe.  The light parts are strings and strings of galaxies. Our galaxy would be one millionth of a fraction of one single point of light in that picture.  Now duplicate that section in every possible direction you can look from every inch of the planet. That's how much we know.

  • A light year is the distance light travels in one year... so... pretty far. :)
