The Expanding Universe, it looked like on the largest scale. At that time the structure of the solar system was fairly well established, and astronomers knew the distance to some of the stars. Furthermore, they knew that we lived in a large “system” of stars. But what did the universe look like beyond this system? How were the stars arranged?作者: BALK 時間: 2025-3-22 13:41
Will the Candidates Please Stand,e know it is there. But why is it hidden from us? There are many possibilities, and many forms it could take. In this chapter I will examine all of them briefly.

Galaxy Formation and Dark Matter,which is best. But what we really need is something that can help us narrow down the candidates. And we do have something. It turns out that the structure of the universe—i.e., the form of the galaxies, clusters, and superclusters in it, and the spaces between them—depends on the dark matter.作者: Nausea 時間: 2025-3-23 01:50
Gravitational Lenses and Dark Matter,nds and focuses light much in the same way an optical lens does. Although the full potential of the gravitational lens has not yet been achieved, tremendous progress has been made, and it may one day provide the breakthrough we are looking for.作者: Tracheotomy 時間: 2025-3-23 06:07 作者: freight 時間: 2025-3-23 13:02
Black Holes,We have seen that black holes are a serious candidate for the dark matter. But I have said little about what they are. In this chapter we will look at their properties, and consider them as candidates.作者: 鑲嵌細(xì)工 時間: 2025-3-23 17:39
Fate of the Closed Universe,f years. If, on the other hand, it is three or four times as great as the critical density it will stop expanding in about 30 billion years. Let’s assume for simplicity that it is twice the critical density; in this case the turnabout will occur in about 50 billion years.作者: Inexorable 時間: 2025-3-23 18:59 作者: 率直 時間: 2025-3-24 01:23
The Missing Mass Mystery Unfolds,ee the dimmer of the two stars, but we know it’s there when we look at the spectral lines of the system: because of the Doppler effect they move back and forth as the two stars revolve around one another. From the period of revolution of the stars we can obtain a relation between the mass of the stars and their brightness (luminosity).作者: 秘方藥 時間: 2025-3-24 03:13
Fate of the Open Universe,rse accurately. And this, in turn, depends on how much dark matter there is. Is there, in fact, enough dark matter to close it (stop its expansion)? As we have just seen, we’re still not certain, but we do know that it is close, and because of this I will discuss both the open and closed universes. This chapter will consider the open universe.作者: 荒唐 時間: 2025-3-24 08:04
Introduction,ars were like tiny diamonds—some solitary, others in pairs and threes. Some were blue, others faintly red. I remember thinking as I looked at them that any one of them could have a planet orbiting it, perhaps with a civilization on it.

Magnetic Monopoles and Other Exotic Particles,with what is called the magnetic monopole. There has been a tremendous amount of interest in it the last few years, not only because it would be a good candidate for dark matter, but also because scientists have predicted that it should exist, and so far—despite extensive searches—it hasn’t been found.作者: Pageant 時間: 2025-3-24 20:41
A Consensus: To Be or Not To Be, the dark matter is. True, we have a number of candidates, but each of them presents problems. Furthermore, we don’t know how the dark matter is distributed—whether it is uniform throughout the universe, or in clumps.作者: flex336 時間: 2025-3-25 01:34 作者: Hectic 時間: 2025-3-25 05:59
