Physics for tonight?)
Added 2022-08-05 19:57:08 +0000 UTCThe light from the stars that you see in the starry sky has only now reached the Earth. Most likely all these stars have long been dead. This happens because the light from these stars travels a huge distance + the Universe is expanding all the time.
And it turns out a delay of several billion years. Which just corresponds to the age of a typical star.
