How "big" is my mind?

Years ago, while contemplating a new galaxy our scientists had discovered and wondering how many more were yet to be found, I asked our Brother: How far is it to the outermost reaches of all galaxies that exist? His answer was: “How long does it take to think of it?” Time, and the illusion of space it creates, is perhaps the ego’s most effective idea of proving there is something apart from and outside of us.
