When we gaze at a star in the Milky Way which is 50,000 light-years away from our sun, we are looking back 50,000 years in time." "The idea is much too big for my little head." "The only way we can look out into space, then, is to look back in time. We can never know what the universe is like now. We only know what it was like then. When we look up at a star that is thousands of light-years away, we are really traveling thousands of years back in the history of space.

Interpretation

What this quote means

This quote reflects on the nature of time and our perception of the universe.

In this quote, Jostein Gaarder explores the profound idea that observing distant stars allows us to witness the universe's past rather than its present. Since light from these stars takes thousands of years to reach us, every glance at the night sky is a journey into the history of the cosmos, illustrating how our understanding of space is inherently tied to the concept of time.

If there is a god, he is not only a wizard at leaving clues behind. More than anything, he's a master of concealment. And the world is not something that gives itself away. The heavens still keep their secrets. There is little gossip amongst the stars. But no one has forgotten the Big Bang yet. Since then, silence has reigned supreme, and every thing there is moving away. One can still come across a moon. Or a comet. Just don't expect friendly greetings. No visiting cards are printed in space.

Superstitious." What a strange word. If you believed in Christianity or Islam, it was called "faith". But if you believed in astrology or Friday the thirteenth it was superstition! Who had the right to call other people's belief superstition?

I believe there is something of the divine mystery in everything that exists. We can see it sparkle in a sunflower or a poppy. We sense more of the unfathomable mystery in a butterfly that flutters from a twig--or in a goldfish swimming in a bowl. But we are closest to God in our own soul. Only there can we become one with the greatest mystery of life. In truth, at very rare moments we can experience that we ourselves are that divine mystery.

When we die, as when the scenes have been fixed on to celluloid and the scenery is pulled down and burnt β€” we are phantoms in the memories of our descendants. Then we are ghosts, my dear, then we are myths. But still we are together. We are the past together, we are a distant past. Beneath the dome of the mysterious stars, I still hear your voice.

Although you may not stumble across a Martian in the garden, you might stumble across yourself. The day that happens, you'll probably also scream a little. And that'll be perfectly all right, because it's not every day you realize you're a living planet dweller on a little island in the universe.

A philosopher knows that in reality he knows very little. That is why he constantly strives to achieve true insight. Socrates was one of these rare people. He knew that he knew nothing about life and about the world. And now comes the important part: it troubled him that he knew so little.

The individuation of dharma practice occurs whenever priority is given to the resolution of a personal existential dilemma over the need to conform to the doctrines of a Buddhist orthodoxy. Individuation is a process of recovering personal authority through freeing ourselves from the constraints of collectively held belief systems.

Nothing seems to me to be rarer today then genuine hypocrisy. I greatly suspect that this plant finds the mild atmosphere of our culture unendurable. Hypocrisy has its place in the ages of strong belief: in which even when one is compelled to exhibit a different belief one does not abandon the belief one already has.
Friedrich NietzscheRead
Too much openness and you accept every notion, idea, and hypothesis-which is tantamount to knowing nothing. Too much skepticism-especially rejection of new ideas before they are adequately tested-and you're not only unpleasantly grumpy, but also closed to the advance of science. A judicious mix is what we need.

In some ways, I had a traditional 'old South' upbringing, meaning that I spent some time in a military school, and acquired an inoculum of the military ethic that is still with me today: honor, duty, loyalty.
