“You’re way too low. You need to get back on course!” I’m soaring through space high above Mars, steering my way towards the ship that’s going to take me back to Earth after hundreds of days stranded on the Red Planet. I’m changing direction using the air escaping from my pierced left glove, which I’m holding behind my back so I can move forward. I look over my shoulder and see the rocket I used to escape hanging against a Martian backdrop; above and around me, there’s only the void. My return home might be in jeopardy.

I change my left hand’s angle and approach a white beam of light, where my commander is waiting to drag me onto her waiting spacecraft. She wraps me in her arms, and I feel a little jolt when our helmets clunk together. Having finally achieved relative safety, I drop the controllers I’ve been holding and lift the Oculus Rift headset I’ve been wearing for the last 20 minutes into the hands of a nearby attendant. I’ve just finished The Martian VR Experience, which is coming to a virtual reality headset near you sometime this year, and the moments I just spent hurtling through the solar system are giving me a new appreciation for the solid footing of this Las Vegas nightclub.

Star Trek is by now said to have encouraged a whole host of current devices from the iPad to the holodeck’s ‘virtual reality’. Now a famous theoretical physicist says that even its teleporter is technically possible, and it could become an actuality before the end of the century. Professor Michio Kaku said that the several breakthroughs required to transport humans rapidly have already been made, and it’s not far when we will be ‘beaming’ across the cosmos. Michio Kaku is a professor at City University in New York. Dr Michio Kaku said “You know the expression “Beam me up Scotty”? We used to laugh at it. We used to laugh when someone talked about teleportation, but we don’t laugh anymore.

Mark Zuckerberg wants to live a bit more like Tony Stark. In a post on Facebook this afternoon, Zuckerberg wrote that he intends to build an AI that can run his home and present him with virtual reality visualizations of his work. “You can think of it kind of like Jarvis in Iron Man,” Zuckerberg writes.

Zuckerberg’s vision starts basic but gets a lot more ambitious. “I’m going to start by exploring what technology is already out there,” he writes. That should be able to handle his initial goals, like controlling “music, lights, temperature, and so on.” He also wants this system to recognize when friends are at the front door and let them in, alert him if his newborn daughter needs attention, and to do all of this only when it recognizes the person speaking. For the most part, that’s all doable even for the non-billionaire home builder. Zuckerberg has already found one product that he likes: “For just music, the Amazon Echo is pretty great. It’s been very useful for controlling music with my voice while both hands are occupied taking care of Max.”

The more challenging aspects of the project include making it work without direct input by him or Priscilla Chan, his wife. “I’m very interested in using voice and face recognition to set lights and temperature as well depending on who is in what rooms, etc,” he writes. “For example, I like rooms colder than Cilla, and but it’s possible to just see who is in what room and adjust the temperatures automatically.”

The feeling you got when you first saw your newborn’s face. That glorious moment when the entire family was laughing over dinner. The epiphany you had when you reached the peak of your favorite mountain. If only you could travel back and experience those instances again.

A group of engineers is hoping to do just that with a virtual reality (VR) system that lets you take 3D videos with your phone and an accompanying virtual reality headset that lets you experience those memories again, whenever you want.

“Family started the idea,” said Justin Lucas, one of the technology’s creators. “Viewing 2D videos is how we look back at past moments. We wanted to create a more immersed feeling when viewing those favorite past moments.” [Best Apps for Virtual Reality Newbies].
