Знаете ли Вы, что такое "усталость света"?
Усталость света, анг. tired light - это явление потери энергии квантом электромагнитного излучения при прохождении космических расстояний, то же самое, что эффект красного смещения спектра далеких галактик, обнаруженный Эдвином Хабблом в 1926 г.
На самом деле кванты света, проходя миллиарды световых лет, отдают свою энергию эфиру, "пустому пространству", так как он является реальной физической средой - носителем электромагнитных колебаний с ненулевой вязкостью или трением, и, следовательно, колебания в этой среде должны затухать с расходом энергии на трение. Трение это чрезвычайно мало, а потому эффект "старения света" или "красное смещение Хаббла" обнаруживается лишь на межгалактических расстояниях.
Таким образом, свет далеких звезд не суммируется со светом ближних. Далекие звезды становятся красными, а совсем далекие уходят в радиодиапазон и перестают быть видимыми вообще. Это реально наблюдаемое явление астрономии глубокого космоса. Подробнее читайте в FAQ по эфирной физике.
