5,Have you seen the film Star Wars? If you have, you’ll know what an evergy - gun is, and a light - sword too. The gigantic space ship in Star Wars can destroy a whole planet in a second or two, and it does so. Fortunately, it isn’t our planet; it belongs to a distant system, far out in space.

The great empty spaces of the universe are no problem in star Wars. The fighters know how to fold space over, like a sheet of paper, so that very distant stars are brought close together; they call

it “hyperspace”. This means, of course, that their ships don’t have to creep along at the speed of light. If they did that, they would take years, even centuries, to reach the battlefield. Hyperspace allows them to travel as “supralight” speed and get there in a couple of hours. It’s good clean fun (健康无害的娱乐) though. We certainly don’t know all about physics yet, but we do have the work of Albert Einstein. He asked us to believe that nothing could travel faster than light through an empty space - but don’t let that miserable idea spoil the film for you, even though all our observations up to now have shown that Einstein was dead right - forget it. Sit back and watch those energy - shells blow up the hated enemy. The Star Wars princess is extremely beautiful. The more we “discover”, the more we must admire Einstein. He knew it all before us - by about 1910 in fact. We observe certain very high speed particles (微粒), and they behave exactly as Einstein predicted they would. We can give them a speed almost equal to light, but they never quite reach light speed. He predicted that a very fast - moving object, as it flashed by a stationary (静止的) observer, would seem to have much greater weight than usual. And that, too, was proved correct.

So far as scientific theory or evidence is concerned, there is no such thing as hyperspace, no such speed as supralight. Space is as we know it, and light speed is the highest possible speed. “But,” say the story - writers, “that’s only true at present. We
