Knowing the Future Makes it Boring

Yet the more surely and vividly you know the future, the more it makes sense to say that you've already had it. When the outcome of a game is certain, we call it quits and begin another. This is why many people object to having their fortunes told: not that fortunetelling is mere superstition or that the predictions would be horrible, but simply that the more surely the future is known, the less surprise and the less fun in living it. [...] The science-fiction in which we have just been ind...

 Habitable Worlds as a Cause for Moral Reflection

In this great celestial creation, the catastrophy of a world, such as ours, or even the total dissolution of a system of worlds, may possibly be no more to the great Author of Nature, than the most common accident in life with us, and in all probability such final and general Doomsdays may be as frequent there, as even Birthdays or mortality with us upon the earth. This idea has something so chearful in it, that I own I can never look upon the stars without wondering why the whole world does ...

 Nemisis

Piet Hut, another Dutch astronomer fifty years younger than Jan Oort, decided to take seriously the possibility that comet showers are periodic. If they are periodic, the theory that they are caused by the random passing-by of alien stars cannot be right. If showers are periodic, they must be explained by a different theory. Piet Hut and his friend Rich Muller found an alternative theory to explain the periodicity in case it turns out to be real. The alternative theory is called Nemesis. Neme...

 Seeing How Species Arise is Similar to Understanding Star...

The way we discovered how species arise resembles the way astronomers discovered how stars “evolve” over time. Both processes occur too slowly for us to see them happening over our lifetime. But we can still understand how they work by finding snapshots of the process at different evolutionary stages and putting these snapshots together into a conceptual movie. For stars, astronomers saw dispersed clouds of matter (“star nurseries”) in galaxies. Elsewhere they saw those clouds condens...
