Merlin, a fictional visitor from the Andromeda Galaxy, Planet Omniscia, has been friends with many of the most important scientific figures of the past including Kepler, da Vinci, Magellan, Doppler, Einstein and Hubble. In this delightful tour of the galaxies, Merlin often recounts his conversations with these historical figures in his responses to popular astronomy questions asked by adults and children alike. Merlin's well-informed answers combine a unique combination of wit and poetry along with serious science explained in refreshingly clear, reader-friendly language.
Dear Merlin: Can a person cross our galaxy in a spaceship during one human lifespan?
Merlin: In 1905, Merlin's good friend Albert Einstein introduced the "Special Theory of Relativity," which predicts that time will tick slower and slower the faster you travel. Were you to embark on such an adventure you could conceivably age as little as you wish, depending of course, on your exact speed. The problem arises when you return to Earth, which will have moved several hundred thousand years into the future and everyone will have forgotten about you.
A skywatcher's book for lovers of the universe by one of its greatest lights.

To the left of the break in the protective vegetation that encircles the camp stands a large clump of sagebrush. The plant's strong branches shield a spacious area near its base that, when covered with moss, is ideal for queens and their litters. Warm scents of milk often flood out from the den entrance and there is an feeling of peace surrounding this place. Even more importantly, it is the safest den in the camp, growing conveniently next to the Warrior Den. Under the shelter of this silver plant the future warriors of Horseclan will be born. For them this is only a stepping stone and it will not take long for the kits here to yearn for the Apprentice Den. However kithood is to be enjoyed and these little cats will spend many moons happily playing mossball or pretending to hunt and fight while their parents look on with pride. When the day does arrive for the young lives that began here to become apprentices one can only hope their parents will be ready to let them go as well. ~ The Nursery, Lilywolf <br> <br>
