This is the history of the invention that is called the Matter Transmitter. MT for short. It begins at the beginning, where all stories should begin, and continues far into the future, for a million times a million years.
Along the way we dip into the river of time and come up with fragments of this history. These particles, brief encounters, will have to stand for the whole, for the river travels for too long a distance and is too deep for us to ever explore it all. Never mind, there are these most interesting things to see along the way.
Throughout history — and prehistory — mankind's lot has always been affected by man's inventions. With the development of the wheel all the varied forms of transportation began. Just think what the canal did to the English countryside and way of life. Or what the railroad, then the airplane, did to the entire world. Everything has changed; nothing is the same.
Now think of the changes that will be wrought by another form of transportation. The Matter Transmitter. All you have to do is step through the screen and you are on the other side of the world.
Or on the Moon.
Or another planet.
Or the far side of the galaxy. Here — step through.
