130 TWO NEW WORLDS 



has been alleged that our solar system is rather 

 an exception in our stellar universe, and that most 

 stars are binaries, and probably unattended by 

 planets. But the earth must be a radiator of 

 supra-light. This is a matter admitting of no 

 doubt whatever. 



The earth carries round the sun annually a 

 quantity of negative electricity, which makes its 

 revolution equivalent to a current of 1 ampere. 

 If the other planets also carry charges, the " supra- 

 light" of the solar system will have a well-defined 

 line spectrum. The wave-length of the supra-light 

 emitted by the earth is 10 18 cm. 



On the whole the chances are just as much in 

 favour of a starry vault in the supra- world as 

 they are with us, since there is no essential change 

 in the geometrical arrangement. 



We cannot very well understand the conditions 

 prevailing in our supra-star, except with reference 

 to the sun. There also we have a gaseous body 

 of very high temperature. If planets are rare 

 accidents, then we may also look for planets in 

 the supra-world ; but a chance visit would not 

 reveal them unless the circumstances were excep- 

 tionally favourable. 



Our galactic system as a whole is most prob- 

 ably non-magnetic, though our solar system is 

 undoubtedly a " molecular magnet." But the mag- 

 netic and other electric forces are very feeble on
