Sir Richard Branson today offered a $ 25,000,000 prize for scientists who find a way to save the planet from the effects of climate change.
Supported by the former US vice-president A1 Gore and other environmentalists, the boss of Virgin Atlantic airlines called for scientists to come up with a way to take greenhouse gases out of the atmosphere.
“What we are doing is making sure we get the most carbon dioxide-friendly planes. We promise that 100% of profits we make from our transportation business are put into things like the prize we've offered today. We shall convince people that we are facing a threat which is urgent and there’s no superhero. We have no hope of a meaningful solution unless we find a way to work together.” he said.
Mr Gore said global warming was man-made and was like to the planet suffering from a “fever”. He said, "Humans had slipped into a way of thinking that was centered on ‘short term satisfaction’, and now meet the challenge of ‘transforming ourselves and changing the structures of everything we do’," he said.
Reacting to the launch of the prize, Tony Jupiter, the Friends of the Earth's director, warned against wasting time waiting for new inventions. He said, "Sir Richard' s initiative (初衷) may encourage inventors to develop a wonder technology to deal with carbon dioxide of the atmosphere. But many of the ways, such as energy efficiency and renewables, already exist, and it is essential that these be put into practice as soon as possible. Moreover, Sir Richard must also look at his business activities and the contribution they make to climate change. The world will find it very difficult to settle climate change if air travel continues to expand and space tourism is developed."

Have you seen the film Star Wars? If you have, you’ll know what an energy–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 observer(静止的参照物), 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 don’t know all about physics yet. Who knows --- who knows if there isn’t another set of facts just waiting to be discovered; another universe perhaps, just round the corner?”

Einstein seems to have been prepared for that too. In his theories he emphasized the word “relative”. Everything --- speed, weight, time, etc. --- is relative to something else. Nothing, by itself is real or absolute. So if there is another universe somewhere, we shall only know about it relative to ourselves. So far there’s no sign of it. But for the future, well, who knows?
