The unidentified girl's father claimed that his ex-wife had exposed their daughter to inappropriate song lyrics and "sexually suggestive" dancing when she took the girl to a Pink concert in 2013.
But Ocean County Judge Superior Court Judge Lawrence R. Jones ruled that the girl's mother had the right to determine what's best for her child while they are together.
"Each parent has a basic constitutional right and ability to exercise reasonable discretion on child-related issues during his or her own parenting time, so long as such choices do not unreasonably
compromise the child's general health, safety and welfare," Jones said.
Jones said he consulted the girl, who was a Pink fan, and found that she had enjoyed the show.
"When all the smoke from the custody litigation clears, it will be self-evident that all which happened here is that a young girl went to her first rock concert with her mother and had a really great time," he added.
Jones also chided "warring ex-spouses" for using the family court system to resolve small differences about child-rearing.
"In a great many of these circumstances, the dispute actually boils down to one parent, or sometimes each parent, attempting to micromanage how the other parent raises the child during his or her own parenting time," Jones said.
It was the first time someone has appeared at the theater as a hologram. "Although I would love to be there in person," he said to the audience, "the idea of being the first person to appear as a hologram at the stage at the Opera House was too good an offer to refuse."
Hawking was taped live from his office at Cambridge University. His daughter, Lucy, and physicist Paul Davies were present on the stage with his hologram.
Hawking spoke of his life and his work, and he touched on how technology is currently influencing daily life. "In a way the internet connects us all together like neurons in the giant brain," he said. "With such an IQ, what won't we be capable of?"
Hawking also received questions from the audience, including a question about how young girls can deal with Zayn Malik leaving the band One Direction.
"Finally, a question about something important," he joked. "My advice to any heartbroken young girl is to pay close attention to the study of theoretical physics. Because one day there may well be proof of multiple universes." He said it's possible there's another universe where Malik is still in the band.
