It has to end somewhere. Scientifically the solar system has more than one end point. More correctly the sun has more than one end point. The sun gives off a constant steam of particles. At earth we are inside this stream, so even here we are still in the sun. The latest new from the voyager mission is has now reached a new boundary, 11 billion miles from earth. Eventually the stream of particles from the sun hits interstellar space and slows down. Other changes, in the magnetic field strength and direction should also happen. Voyager will keep going and going, so it will be become the first man made object to leave the Sun. The big question is, with only a few dozen years of battery left, will we know when it does so?
