Астрономы рассказали, каковы шансы человечества пообщаться с инопланетянами

Учёные высказали предположение, что вряд ли какая бы то ни было цивилизация инопланетян могла бы просуществовать более ста тысяч лет. В то же время, едва ли радиосигналам потребуется меньше времени для того, чтобы преодолеть расстояние до Земли. Таким образом, даже если Млечный путь действительно наполнен инопланетными радиосигналами, специалисты предполагают, что они достигнут Земли значительно позже, чем в точке отправки не останется существ, готовых получить ответ.

Солнечная система располагается на расстоянии примерно 26 тысяч световых лет от центра галактики, и за 80 лет с момента появления радиовещания первые сигналы покрыли менее тысячной доли процента пространства, занимаемого галактикой.

При этом специалисты предполагают, что количество инопланетных сигналов, которые получает Земля в каждый момент времени, должно соответствовать количеству цивилизаций, способных такие сигналы отправлять, пусть это могут быть уже другие инопланетяне. По словам учёных, в следующей работе они зададутся вопросом, как в этой связи понимать отсутствие каких бы то ни было инопланетных сигналов, зафиксированных на сегодняшний день.

Одним из авторов исследования стал Фрэнк Дрейк, автор знаменитой «формулы», названной его именем. Уравнение Дрейка предназачено для определения числа внеземных цивилизаций в Галактике, с которыми у человечества есть шанс вступить в контакт. Она включает в себя такие показатели, как количество звёзд, образующихся в год в нашей галактике, доля звёзд с планетами, процент планет, пригодных для жизни, вероятность появления на них живых организмов и так далее. Стоит отметить, что о конкретных числовых значениях некоторых из этих переменных человечество пока может лишь догадываться.

With havin so much content do you ever run into any issues of plagorism or copyright infringement? My blog has a lot of completely unique content I’ve either written myself or outsourced but it appears a lot of it is popping it up all over the internet without my agreement. Do you know any methods to help reduce content from being ripped off? I’d genuinely appreciate it.
