NASA is still dithering as to whether Voyager has left our solar system. It seems like an easy call, but maybe when Voyager notes certain conditions, then we will actually know how big our solar system is.

What they are looking for is:

1. An increase in high-energy cosmic rays originating from outside our solar system

2. A drop in charged particles emanating from the sun.

3. A change in the direction of the magnetic field.

Now with Elvis, I heard it was easier. They just observed when the deep fried peanut butter and banana sandwiches stopped disappearing.
