Heat and light in amazing quantities pourfrom it without ceasing.Where does this energy come from? Enormous umbro shorts umbro shorts red glowing gases canbe seen shooting outwards umbro shorts the sun, like flames from a fire, forthousands a.

before thesun became too cold umbro shorts support life many millions of years would berequired.It was suggested at umbro shorts time that falls of meteoric matter into the sunwould account for the sun's heat. This position is hardly tenable now.The mere bulk of umbro shorts umbro shorts matter required by the hypothesis, apartfrom other reasons, is against it. There is undoubtedly an enormousamount of meteoric matter moving about within the bounds of the umbro shorts but most of it seems to be following definite umbro shorts round thesun like the planets. The stray erratic quantities destined to meettheir doom by umbro shorts umbro shorts umbro shorts sun can hardly umbro shorts sufficient to accountfor the sun's heat.Recent study of radio-active bodies has suggested another factor thatmay be working umbro shorts along with the force of gravitation tomaintain the sun's store of umbro shorts In radio-active bodies certain atomsseem to be undergoing disintegration. These atoms appear to be splittingup into very minute and primitive constituents. But since matter may besplit up into such.
