This is the first time that humanity has transitioned from our solar system's solar bubble into interstellar space. The plasma wave science team detected increased pressure in the heliosphere. The pitch of electron plasma oscillation confirmed that Voyager entered the Oort Cloud. The shuttle passed through the heliopause; this is the boundary between solar and interstellar plasma.
It is apparent to me that the dark matter of the universe is detectable by its density. And, its density verifies its weight. I theorize that these heavy densely enmeshed charged particles fuse and are so tightly wound that they explode into photon emitting light, thus, star birth.
