Световой год – это расстояние, которое свет преодолевает за год беспрепятственного пути в вакууме. Поскольку абсолютная скорость света, то есть скорость распространения электромагнитных волн в вакууме, является константой (постоянной величиной), то не трудно подсчитать, что световой год составляет приблизительно 9,46 триллионов км.

Для наглядности: солнечный свет достигает поверхности Земли за 8 световых минут и 20 световых секунд, а расстояние до ближайшей к нам звезды – Альфы Центавра – 4,37 световых лет.

You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences.
