{"title":"Galactic Dark Matter and Terrestrial Periodicities","authors":"S. Clube, W. Napier","doi":"10.21236/ada359882","DOIUrl":"https://doi.org/10.21236/ada359882","url":null,"abstract":"Abstract : Analysis of recent geological databases reveals the presence of a ^26.5 Myr periodicity in the terrestrial record of the last ^200 Myr. The same periodicity is found to be present, at a high confidence level, in the record of impact cratering on Earth. It thus appears that global disturbances are modulated or caused largely by exogenous forcing. The likely source is a periodic comet influx caused by Oort cloud disturbance as the Sun oscillates vertically through the Galactic disc. The Earth may thus be regarded as a probe of the disc environment; and to account for the periodicity, the Galactic disc is required to have a substantial dark matter component (^approx .15 molar mass/cu pc). The purpose of this paper is to review the relevant observational framework, and to describe the basic astro- and geo-physical processes which now seem to underpin evolution on Earth. The resulting current hazard to Earth, amounting to a more substantial input and explosion megatonnage in toto, is both more complex and more profound.","PeriodicalId":194823,"journal":{"name":"Quarterly journal of the royal astronomical society","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125447640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
