Elon Musk shares his plan to make humans a multi-planetary species

The SpaceX chief ruled out moving the moon because it is too small, and Venus too, as it was ‘not at all like the goddess’.

Tesla and SpaceX Chief Executive Elon Musk, in a paper called “New Space”, has outlined a vague plan to make humans a multi-planetary species.

Musk has proposed the development of a huge spacecraft to mass transport people to Mars, which he has estimated would cost $10 billion dollars per person. He said a priority was to get the cost of moving to the red planet reduced by five million percent, to the average cost of a house in the United States.

Musk used a venn diagram to show the current situation, with one circle to indicate people who want to live on Mars and another circle to represent people who can afford to do so. “What we need to do is to move those circles together,” Musk said. He said it would take around 40-100 years to create a self-sustained civilisation of around one million people on Mars.

“Given that Mars would have a labor shortage for a long time, jobs would not be in short supply,” Musk said during a presentation of his proposal. The billionaire entrepreneur has ruled out considering the moon as an option. “I actually have nothing against going to the moon, but I think it is challenging to become multi-planetary on the moon because it is much smaller than a planet.”

He said Venus was not viable either as it was “not at all like the goddess”, but a “super high-pressure acid bath”.

His plan, however, was criticised by scientists in the field. “It’s a wild-eyed investment pitch, pumped up by the enthusiasm of credulous fanboys brought up on comic book sci-fi, wrapped in evangelism of saving humanity from itself and the problems we’ve wrought on this planet, a kind of modern day manifest destiny,” The Guardian quoted Mark McCaughrean, senior adviser for science and exploration at the European Space Agency as saying.

“In some ways it is not that complicated, actually,” Musk said about creating a spacecraft that could transport around 100 people to Mars. The SpaceX chief said developments in the area could reduce the travel time to 30 days. “It would be quite fun to be on Mars because you would have gravity that is about 37% of that of Earth, so you would be able to lift heavy things and bound around,” Musk said.

The pioneering technologies that will govern the future of television

Home entertainment systems are set to get even more immersive.

Immersive experience is the core idea that ties together the next generation of cinematic technologies. Cutting edge technologies are now getting integrated into today’s home entertainment systems and challenging the limits of cinematic immersion previously achievable in a home setting. Here’s what you should know about the next generation of TVs that will grace your home.

OLED Technology – the new visual innovation in TVs

From the humble, grainy pictures of cathode ray tube TVs to the relatively clarity of LED and LCD displays, TVs have come a long way in improving picture quality over the years. The logical next step in this evolution is OLED displays, a technology that some of the best smartphones have adopted. While LED and LCD TVs make use of a backlight to illuminate their pixels, in OLED displays the pixels themselves emit light. To showcase darkest shades in a scene, the relevant OLED pixels simply don’t light up, creating a shade darker than has ever been possible on backlighted display. This pixel-by-pixel control of brightness across the screen produces an incomparable contrast, making each colour and shade stand out clearly. OLED displays show a contrast ratio considerably higher than that of LED and LCD displays. An OLED display would realise its full potential when supplemented with HDR, which is crucial for highlighting rich gradient and more visual details. The OLED-HDR combo is particularly advantageous as video content is increasingly being produced in the HDR format.

Dolby Atmos – the sound system for an immersive experience

A home entertainment system equipped with a great acoustic system can really augment your viewing experience far beyond what you’re used to. An exciting new development in acoustics is the Dolby Atmos technology, which can direct sound in 3D space. With dialogue, music and background score moving all around and even above you, you’ll feel like you’re inside the action! The clarity and depth of Dolby Atmos lends a sense of richness to even the quieter scenes.

The complete package

OLED technology provides an additional aesthetic benefit. As the backlight is done away with completely, the TV gets even more sleek, so you can immerse yourself even more completely in an intense scene.

LG OLED TV 4K is the perfect example of how the marriage of these technologies can catapult your cinematic experience to another level. It brings the latest visual innovations together to the screen – OLED, 4K and Active HDR with Dolby Vision. Be assured of intense highlights, vivid colours and deeper blacks. It also comes with Dolby Atmos and object-based sound for a smoother 360° surround sound experience.

The LG OLED TV’s smart webOS lets you fully personalise your TV by letting you save your most watched channels and content apps. Missed a detail? Use the Magic Zoom feature to zoom in on the tiniest details of your favourite programs. You can now watch TV shows and movies shot in 4K resolution (Narcos, Mad Max: Fury Road, House of cards and more!) as they were meant to be watched, in all their detailed, heart-thumping glory. And as 4K resolution and Dolby Atmos increasingly become the preferred standard in filmmaking, TVs like LG OLED TV that support these technologies are becoming the future cinephiles can look forward to. Watch the video below for a glimpse of the grandeur of LG OLED TV.
