We are 13.7 billion light-years from the edge of the observable universe; that's a good estimate with well-defined error bars and with the available information, I predict that I will always be with you.

We are 12 billion light-years from the edge. That's a guess — no-one can ever say it's true, but I know that I will always be with you.
Katie Melua
It is almost as difficult to make a man unlearn his errors as his knowledge. Mal-information is more hopeless than non-information; for error is always more busy than ignorance. Ignorance is a blank sheet, on which we may write; but error is a scribbled one, on which we must first erase. Ignorance is contented to stand still with her back to the truth; but error is more presumptuous, and proceeds in the same direction. Ignorance has no light, but error follows a false one. The consequence is, that error, when she retraces her footsteps, has further to go, before she can arrive at the truth, than ignorance.
Charles Caleb Colton
The more I learn about light the more I realize, man, we don't know anything about light... It's just bizarre... a particle has it's own proper time which slows down as you speed up. But at the speed of light... there's no time. That's bizarre ... that we can, right now, as you know, see — interact with the light that has come from the birth of the universe. So ... from our point of view, that light traveled for 14 billion years but from the point of view of the light it's the moment of creation.
Brian Swimme
The light has gone out, I said, and yet I was wrong. For the light that shone in this country was no ordinary light. The light that has illumined this country for these many years will illumine this country for many more years, and a thousand years later, that light will be seen in this country and the world will see it and it will give solace to innumerable hearts. For that light represented something more than the immediate past, it represented the living, the eternal truths, reminding us of the right path, drawing us from error, taking this ancient country to freedom.
Jawaharlal Nehru
Looked at from the perspective of twentieth-century earth, we see three great stages in the dynamic process of the universe. To this whole process, as it spreads out over perhaps ten billion years of time and ten billion light years of space, we give the name evolution, and we see three great patterns within it. The first is physical evolution. This presumably started with the development of the most elementary particles (whatever they may be); then of neutrons, protons, electrons, and radiations; then of elements from hydrogen to uranium and beyond formed by combining protons and electrons; then of chemical compounds; then finally of increasingly complex molecules from amino acids, and proteins to the great watershed of DNA, the beginnings of life.
