The teenage children of actors Will Smith and Jada Pinkett Smith have always been perceived as being ahead of their time.

In 2012, 12-year-old Willow released a single called Whip My Hair which went platinum. Earlier this year she was photographed in bed with a shirtless 20-year-old male "friend", while Jaden, who is now 16, has starred alongside his father in numerous Hollywood blockbusters, recorded two albums and now created an app called "The Jaden Experience".

However, speaking to The New York Times' T Magazine, time is a concept they don't believe in.

"I mean, time for me, I can't make it go slow or fast, however I please, and that's how I know it doesn't exist," 14-year-old Willow said.

"It's relative to beings and other places. But on the level of being here on earth, if you are aware in a moment, one second can last a year. And if you are unaware, your whole childhood, your whole life can pass by in six seconds," Jaden said.

The interview, the siblings' first-ever joint Q&A session, took place "on a bluff overlooking the Pacific Ocean" and had to be "edited and condensed" due to the pair's long-winded thoughts on subjects such as Prana energy, happiness, the problems with kids who go to "normal school" and their various creative processes and outlets.

Jaden, a prolific tweeter and Kendall Jenner's best friend, hopes to one day to be "just the most craziest person of all time" and do "Olympic-level things" while Willow is a little more philosophical.

"I think by the time we're 30 or 20, we're going to be climbing as many mountains as we can possibly climb," she said.

While many of their peers may still be making their way through the Harry Potter series, the Smith children have a variety of texts on their bedside tables. Willow is working her way through "Quantum physics. Osho" and Jaden is devouring a number of "ancient texts, things that can't be pre-dated".

One explanation for Willow's choice of unusual reading material could be because she can't find any young adult fiction to inspire her, which is why at age six, she began writing her own according to Jaden.

"There's no novels that I like to read so I write my own novels, and then I read them again, and it's the best thing," she said.

It's hard to believe they understand what they are reading considering Jaden can't seem to execute a clean metaphor.

"When you're thinking about something happy, you're thinking about something sad. When you think about an apple, you also think about the opposite of an apple. It's a tool for understanding mathematics and things with two separate realities. But for creativity: That comes from a place of oneness. That's not a duality consciousness. And you can't listen to your mind in those times — it'll tell you what you think and also what other people think," he said.

Don't think a basic grasp on the English language is enough to send these teens to high school though. They are both homeschooled after the school they did attend – the non-traditional New Village Leadership Academy that was founded by their parents which taught aspects of Scientology – was shut down last year due to a lack of funding.

"Here's the deal: School is not authentic because it ends...Kids who go to normal school are so teenagery, so angsty," Jaden said.

"You never learn anything in school. Think about how many car accidents happen every day. Drivers ed? What's up? I still haven't been to driver's ed because everybody I know has been in accident. I can't see how driver's ed is really helping them out."

"I went to school for one year. It was the best experience but the worst experience. The best experience because I was, like, 'Oh, now I know why kids are so depressed', but it was the worst experience because I was depressed," Willow added.
