evidence, particularly in meteorites, that shorter-lived isotopes existed at some point in the past, but have since become extinct. Some of these isotopes and their half-lives are given in Table II. This is conclusive evidence that the solar system was created longer ago than the span of these half lives! On the other hand, the existence in nature of parent isotopes with half lives around a billion years and longer is strong evidence that the Earth was created not longer ago than several billion years. The Earth is old enough that radioactive isotopes with half-lives less than half a billion years decayed away, but not so old that radioactive isotopes with longer half-lives are gone. This is just like finding hourglasses measuring a long time interval still going, while hourglasses measuring shorter intervals have run out.
Skout is the largest location-based dating app, with more than 5 million subscribers. Originally targeting advlts, the company started a separate service for 13- to 17-year-olds last year after kids started using the app.
The services start by helping customers build their profile, a practice already offered by several online dating sites. However, the service continues with picking out potential matches, the writer then sends introductory e-mails to the possible matches and continues messaging back and forth until they can confirm the date. Although the service was used at first mainly by men, this has changed with more ladies using this service as well.
