If you’ve ever peeked your head out at night at the countryside and gazed at the stars, I bet you could feel the awe that the night sky provokes.

Like many other hobbie or professional astronomers, I feel that observing the sky raises deep philosophical questions. I’m constantly meeting people who tend to forget that the world isn’t only what happened today in the human society. Stargazing allows you to appreciate the position of human beings in the Universe. Here are a list of things I enjoy thinking about:

• Humans are Insignificant
• Trying to grasp the size of the universe
• Imagining infinity
• We’re all going to die one day or the other
• The Sun is only one star out of billions
• And many others…

There is a branch of astronomy that is quite theoretical, called Cosmology, and that sometimes gets quite close to philosophical ideas. I love that.
