Oort Quotes

Imagine we could accelerate continuously at 1 g-what we're comfortable with on good old terra firma-to the midpoint of our voyage, and decelerate continuously at 1 g until we arrive at our destination. It would take a day to get to Mars, a week and a half to Pluto, a year to the Oort Cloud, and a few years to the nearest stars. ~ Carl Sagan

Astronomers suspect that the Oort Cloud could extend as far as three light-years from our solar system. That is more than halfway to the nearest stars, the Centauri triple star system, which is slightly more than four light-years from Earth. If we assume that the Centauri star system is also surrounded by a sphere of comets, then there might be a continuous trail of comets connecting it to Earth. It may be possible to establish a series of refueling stations, outposts, and relay locations on a grand interstellar highway. Instead of leaping to the next star in one jump, we might cultivate the more modest goal of "comet hopping" to the Centauri system. This thoroughfare could become a cosmic Route 66. ~ Michio Kaku

I don't care what your Oort woman wants you to steal for her," she says. "You already did your worst. You stole what could have been. From me and from yourself. And you can never have it back. ~ Hannu Rajaniemi

We can't see even into the Oort cloud, so we don't actually know that it is there. Its existence is probable but entirely hypothetical.1 About ~ Bill Bryson

Pluto is about 40 AUs from us, the heart of the Oort cloud about fifty thousand. In a word, it is remote. But ~ Bill Bryson

Even today, more than eighty years after Oort's bold guess, we still don't have a clue what this dark matter is made of. We know it exists. We know where it is. We have maps of its presence within and around galaxies throughout the universe. We even have stringent constraints on what it is not, but we have no clue what it is. And yes, its presence is overwhelming: for every one kilogram of ordinary matter made out of neutrons and protons and electrons, there are five kilograms of dark matter, made out of who-knows-what. ~ Christophe Galfard
