Unexpected observations due to Interstellar warming?
Ancient man thought the earth was flat and covered by a dome with lights glued to the dome. They were so primitive.
We now know that the earth is a globe and one of several globes circling a star inside a big sphere (heliopause) with lights glued all over it.
Except the voyagers punched two holes in the heliopause. It was easy because, unlike the moon, the heliopause really IS made of cheese.
