KNOWLEDGE. 



December, 1911. 





Presently the capturing power of the third body 

 lessens so much that the central attraction almost 

 ceases, and the walling-in material is now urged 

 forward by its own onward velocitx'. The onward 

 motion takes it away from the centre, and the great 

 furnace being no longer fed will soon have quite burnt 

 itself out. Notice that after pressure ceases to expel 

 material, atomic kinetol will continue to carr\' awav 

 molecules of low weiglit. This tangential motion 

 carries the material forward in the mode described in 

 the case of double spiral nebulae. The great Milk\- 

 Way thus gradually spreads itself to the vast dimen- 

 sions to which it has 

 attained. The dimen- 

 sions of cosmic s\stems 

 appear always to be of 

 enormous areas, and 

 consequently the great 

 central furnace would 

 [)robabi\- occupy but a 

 small ratio of the wiiole. 

 The two vast systems 

 would be proceeding 

 onward, in opposite 

 directions, outside of 

 the sphere of central 

 influence, and it is this 

 continued original mo- 

 tion that gives us the 

 two majestic streams of 

 stars whose existence 

 has been demonstrated 

 h\ a number of inde- 

 pendent workers. 



It is probable that 

 ever\- bodv and system 

 in the universe possesses 

 more or less rotation, 

 and tile old cosmic 

 system that, b\- inter- 

 penetrating the pri- 

 mordial, went to the 

 making up of our N'irile 

 uni\erse, most probably 

 liad a rotation of its

during the impact, and 



it is almost certainly a 

 continuance of this motion that is seen in those 

 great streams of stars that called my attention 

 to the probable origin of the Galactic Universe. 

 There is one verv definite principle of impact. It 

 is that all motion developed during the collision 

 tends to regularit}-, and all previously existing 

 motions tend to disturb this order. 



Summary. 



This, then, appears to be the motie of origin of the 

 Sidereal Universe. Two cosmic systems of \'ast 

 dimensions, one primordial and the other mature 

 or decaying, approached one another, draw n together

Diagram — oblique view — of the constitution of the Galactic- 

 System. It is made up of three parts: — 



I. — A vast double spiral ring of stars. In tliis belt the dots repre- 

 sent the star clusters, the temporary, variable, double, and 

 Wolf-Rayet stars and planetary nebulae, these last being 

 gaseous. The vast irregular nebulae such as that of Orion 

 are also here. 



II and III. — The two polar caps of the same System, mainly 

 composed of White Nebulae with, as a rule, continuous 

 spectra. These are largely double spirals, as shown in the 

 diagram - 



bv mutual attraction. They obliqueh' interpene- 

 trated one another and produced a vast central 

 furnace, from which were expelled the extensive caps 

 of nebulae that now clothe the two polar regions of our 

 sidereal system. This axial extrusion, and selective 

 escape, caused the central furnace to burn itself out: 

 the released centrifugal force carried the walling-in 

 material, stars and so on, to x'ast distances in space, 

 and formed the Milky Way, In this Milky Way 

 the opposite procession of the two streams of stars, 

 aided by attraction and other agencies, caused 

 collisions of dead and \ivid suns, and these 



collisions produced, as 

 already described, tem- 

 porar\\ variable, double, 

 and Wolf-Rayet stars, 

 planetar\- nebulae and 

 star clusters. The whole 

 of these bodies represent 

 the wreckage of col- 

 liding suns, and are all 

 found wherever stars 

 crowd and probablv 

 collide. Because these 

 impacts possess such a 

 wonderful buildin 

 power this theory 

 impact is sometimes 

 called " the principle of 

 constructive collision." 



The above sketch 

 shows how remarkablv 

 the actual facts of the 

 order of distribution of 

 the Universe correspond 

 with the dvnamical de- 

 duction made so many 

 years ago. It must be 

 remembered that the 

 most strikinglv confirma- 

 torv facts are discoveries 

 made many years after 

 the deductions were 

 worked out. Some of 

 the more convincing 

 and sensational of these 

 will be better understood 

 when we have studied 

 the agencies that show-

On this Earth, and apparently in the Solar

 is generated, cars travel, rooms are warmed, and 

 light appears. But as the outcome of it all. low
