Using the amazing new technology he has developed, a brilliant young scientist creates an experimental environment that he hopes to use for connecting with a parallel universe. After waiting for two weeks to be sure his experimental environment is stable he cautiously enters - only to find it is already occupied. The scientist works hard to ensure that his new technology and its underlying physics is introduced in a thoughtful and measured way to the universes that he is able to make contact with. Over time, he comes to understand that a scientist who opens up a new area of scientific discovery has almost no control over how it will eventually be used. Published originally as three separate novels, this edition combines all three for your interest and enjoyment.
