I was reminded of this because there is very little sun in LA right now. Its a joke here
Just how big is the universe?
Our sun is about 4.6 billion years old. It should last for another 10 billion years before it totally burns out - give or take a few million years. So, if we sent a message thru space to one of the distant planets we can see, we would not get a return message before our solar system was defunct - gonzo - caput. Yikes!
