Interstellar travellers should be "motivated, tolerant and nice".
Star trekking: space voyagers should be one big family.
One hundred and sixty fertile, motivated, English speakers could make it to distant stars, researchers have worked out. But generations down the line, returning voyagers may speak an alien tongue.
Travel to planets orbiting other stars will soon be technically possible, the meeting of the American Association for the Advancement of Sciences in Boston heard last week. But the 200-year odyssey will require a certain kind of crew.
Language of intergalactic love
Prospective couples should woo in English, said linguist Sarah Thomason of the University of Michigan in Ann Arbor. Global politics would probably dictate a multinational mix, but the current international language is the most obvious choice for conversation.
But if the journey takes 500 years, home and ship "wont be able to talk to each other", Thomason predicts. Down-to-Earth words like horse and truck would have no meaning on board, and the slang of interstellar adolescents would diverge from Earth-speak. The crew would have to be beamed language lessons, Thomason said.
Temperament is also critical. "You want motivated, tolerant, nice people," said Moore. This should ensure future generations dont lose interest in the mission and head for the nearest hospitable asteroid belt. Whether the band would actually get on would be more a matter of luck, the researchers conceded.
The exercise is not science fiction, explained space scientist Geoffrey Landis of the NASA Glenn Research Center, Cleveland. Several ways to reach other solar systems have been proposed in recent years. These include using a laser beam projected from Earth to push a vast space sail. Such a ship might travel at 30,000 kilometres per second - around a tenth of light speed.
"Theres actually been some testing done," revealed Landis: "Ultimately, this is going to happen." No one is taking crew applications yet, however.

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.
This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.
Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition, which enables extremely precise nuclear clocks. TU Wien (Vienna) is part of both teams.
If you want to build the most accurate clock in the world, you need something that "ticks" very fast and extremely precise. In an atomic clock, electrons are...
Researchers from Chalmers University of Technology have demonstrated a detector made from graphene that could revolutionize the sensors used in next-generation space telescopes. The findings were recently published in the scientific journal Nature Astronomy.
Beyond superconductors, there are few materials that can fulfill the requirements needed for making ultra-sensitive and fast terahertz (THz) detectors for...
A supersolid is a state of matter that can be described in simplified terms as being solid and liquid at the same time. In recent years, extensive efforts have been devoted to the detection of this exotic quantum matter. A research team led by Tilman Pfau and Tim Langen at the 5th Institute of Physics of the University of Stuttgart has succeeded in proving experimentally that the long-sought supersolid state of matter exists. The researchers report their results in Nature magazine.
In our everyday lives, we are familiar with matter existing in three different states: solid, liquid, or gas. However, if matter is cooled down to extremely...
