Sample text

Particles of space dust typically plunge into the atmosphere at a speed in excess of 30,000 miles per hour. This high speed generates intense friction, making the air around the particle so hot that it glows. In other words, the flash of a meteor is the glow of hot air surrounding a high-speed particle, rather than the particle itself. The flash ends when the particle has fully disintegrated. Most of the dust particles that crash into Earth were shed by comets that passed near Earth’s orbit. We get annual meteor showers because our planet crosses the same trails of comet dust at the same time each year.

Today, many different scientists have many different ideas about what the new theory of gravity should be, but ultimately, when the evidence comes in, we’ll be able to choose among the competing ideas and come to agreement about which ones must go and which ones are worth taking forward into the future. Hallmarks of Modern Science We’ve discussed how the Copernican revolution gave rise to modern science, but we still haven’t said exactly what science is. Indeed, you may have noticed that I’ve described science in several different ways already.

I’ll discuss this technology in some depth in chapter 8, but for now I can put it to you like this: Detecting a planet the size of Jupiter in another star system is rather like detecting a marble in a haystack from a distance of thousands of miles away. It is truly astonishing that we can now do this successfully for many Jupiter-size planets, and perhaps not too surprising that we cannot yet do it for planets the size of Earth, which would be like pinheads in the same haystack. Scientists are rapidly improving their planet-detection capabilities, however, and a NASA mission called Kepler, scheduled for launch in 2009, ought to be capable of finding at least a few Earth-size planets.
