Next January Stephen Hawking will be 74 years old. He has lived much longer than most individuals with his debilitating condition. In addition to being an unquestionably gifted cosmologist, he has invited controversy by supporting the pro-Palestinian, Israel-BDS boycott and warning about the dangers of alien invaders who tap into our interstellar greetings

Antisemitism, notwithstanding, this man is a mental giant. He is Leonardo. He is Einstein. Like them, his discoveries and theories will echo for generations beyond his life on earth. He is that genius.


Forty years ago, when Stephen Hawking still had mobility, he delivered a paper on a mystery regarding information-loss for entities that cross the event boundary of a black hole.

In the mid 1970s, Astronomers were just discovering black holes and tossing about various theories about the event horizon and its effect on the surrounding space-time. Many individuals still considered black holes to be theoretical. Hawking’s analysis of the information paradox seemed extremely esoteric. Yet, last month (Aug 2015) , at Sweeden’s KTH Royal Institute of Technology, Hawking presented a possible solution to the paradox that he sparked.

I can barely understand the issue and cannot articulately rephrase the problem. But my interest in the black hole event horizon takes a back seat to my interest in the amazing tool created to compensate for the famous cosmologist’s handicap. Watch closely as Stephen Hawking offers a new theory that provides a possible explanation for the paradox.

Near the end of the video (beginning at 7:22), the camera begins a steady zoom up to Hawking’s face. Unlike a year ago, when he could still smile at a joke or move his eyes, he now appears completely motionless. Throughout his speech, there is no sense of animation—not even a twitch—with or without purpose. His eyebrow doesn’t move, his fingers are not restless, he doesn’t blink anymore.

Hawking-smile-s

So, how, then, does Hawking speak with normal cadence and just a short delay between sentences? (If we assume that his computer adds emphasis without additional effort, I estimate that his ASCII communications rate is roughly equivalent to a 1200-baud modem, circa 1980). Yet, clearly, there must be a muscular conduit between thought and speech. How is it that his thoughts are converted to speech at almost the same rate as someone who is not paralyzed?

That magic is enabled by a tiny camera that monitors a slowly deteriorating cheek muscle. It is Hawking’s last connection to the outside world. What began as index cards with words and then an Apple II computer, has evolved into a sophisticated upgrade process involving cutting edge analysis of the professor’s slightest tick combined with sophisticated computing algorithms. The camera and software that interprets this microscopic Morse code is tied to a process that optimizes options for successive words and phrases. He is actually communicating at far less than 1200 baud, because—like a court stenographer—he employs shorthand and Huffman encoding to compress words and phrases into his twitch pipeline. Drawing on a powerful processor and connected to the Web, his gear is constantly upgraded by a specialized Intel design team. StenographerThey are engaged in a race to offer Hawking the potential for communication up until he has no capacity for interaction at all.

In a recent documentary by Hawking himself,* he laments the likely day when he will no longer have any capacity for output at all. No ability to discuss physics and cosmology; no way to say “I need help” or “I love you”; no way to show any sign of cognition. At that time, he reflects, the outside world will no longer be certain that there is anything going on behind his blank stare. They will never really know when or if he wants them to pull the plug. Even more mind boggling, humanity will never know what secrets his brilliant mind has unlocked to mysteries of the cosmos.

While NASA has already shown us Pluto’s best images yet, the administration is anything but done blowing our minds. What you see above is an enhanced high-resolution color view of Pluto, created with a combination of blue, red and infrared images. NASA says this photo, taken by New Horizons spacecraft, highlights Pluto’s diverse landforms and shows us its complex geological and climatological story — as much as scientists have been able to figure out, anyway. Over the past few months, NASA’s shared many things related to Pluto, including a closer look at its desolate surface and icy mountain range.

The dark, fingerlike features that creep down steep Martian slopes in warm weather continue to puzzle scientists.

These “recurring slope lineae” (RSL), which have been spotted by NASA’s Mars Reconnaissance Orbiter (MRO) at low and middle latitudes on the Red Planet, fade during cooler months but come back again annually at nearly the same locations over multiple Martian years.

Scientists continue to debate the true nature of the RSL phenomenon; no guess as to what they are and why they occur yet satisfies all observations. And just how RSL sites should be explored generates spirited debate, as evidenced by the discussions that emerged during the second Mars 2020 Landing Site Workshop, which was held last month in Monrovia, California.

Calculations show that if the wormhole’s throat is orders of magnitude longer then the width of its mouth, it does indeed create Casimir energy at its centre.


Cambridge Physicists Find Wormhole Proof:-Physicists at the University of Cambridge have established a theoretical groundwork for the reality of wormholes, which are pipes that join two different points in space-time. If a part of information or physical object could pass through the wormhole, it might open the door to time travel or immediate communication through huge distances. “But there’s a problem: Einstein’s wormholes are extremely unsteady, and they don’t stay open long enough for something to pass over.” In 1988, physicists reached the deduction that a type of negative energy called Casimir energy might keep wormholes open.

The hypothetical solution established at Cambridge has to do with the properties of quantum energy, which conveys that even vacuums are teaming by means of waves of energy. If you visualize two metal plates in a vacuum, some waves of energy would be excessively big enogh to fit between the plates, meaning that the space-time among the plates would have negative energy. “Under the right circumstances, could the tube-like shape of the wormhole itself generate Casimir energy? Calculations show that if the wormhole’s throat is orders of magnitude longer then the width of its mouth, it does indeed create Casimir energy at its centre.”

Stanford engineers have developed a transparent silicon overlay that can increase the efficiency of solar cells by keeping them cool. The cover collects and then radiates heat directly into space, without interfering with incoming photons. According to a local HVAC Spokane, WA company, “If mass-produced, the development could be used to cool down any device in the open air for instance, to complement air conditioning in cars.”

After a full day in the sun, solar cells in California can approach temperatures of 80° C (175° F), even in winter months. Excessive heat can pose problems because, while the cells need sunlight to harvest energy, they also lose efficiency as they heat up. A standard silicon cell, for example, will drop from 20 to 19 percent efficiency by heating up just 10° C (18° F) or so.

Laptops address the overheating problem with the help of carefully engineered fans and heat sinks, but for solar panels and other devices that work in the open air, space itself could serve as heat sink par excellence. The coolness of space, approaching absolute zero, would negate the need for elaborate and expensive heat dissipation contraptions if only we had a way to access it from the ground.

You’ve probably seen a few attempts at recreating worlds in game engines, but never at this level of detail. Artist Jason B is working on the Enterprise-D Construction Project, an Unreal Engine-based virtual tour that aims to reproduce all 42 decks in the Enterprise from Star Trek: The Next Generation. While it’s not quite photorealistic, the attention to detail in this digital starship is already uncanny — the bridge, shuttle bay and other areas feel like lived-in spaces, just waiting for the crew to return. Jason is drawing on as much official material as he can to get things pixel-perfect, and he’s only taking creative liberties in those areas where there’s no canonical content.

The project is currently just a hobby, but there might be more in the cards if everything goes smoothly. Jason is considering populating the ship, offering a chance to explore the outsides of other locations (such as Deep Space Nine) and even introducing game mechanics. Whether or not those happen will depend on many things falling into place, however. The creator is thinking about crowdfunding campaigns to help with his work, and there’s the looming question of licensing: he’ll likely need CBS’ approval to release anything, especially if he wants to charge for it. Even if it amounts to little more than some screenshots and video, though, it’s an impressive feat.

Right now, Mars is a frozen, lifeless, and entirely inhospitable place.

Yet the Red Planet holds great promise, and SpaceX CEO Elon Musk recently discussed its future with comedian and television host Stephen Colbert.

Musk, who hopes to build a colony of 1 million people on Mars, told Colbert that there are two ways to warm the global temperatures on Mars, which would help transform it from a barren wasteland into a hospitable, Earth-like planet.

Astronauts typically try to avoid starting fires in space, but new research on the behavior of flames in orbit could have benefits closer to home. In fact, this fiery research could lead to more-efficient car engines that contribute less pollution to the environment, according to a new study.

A series of experiments aboard the orbiting complex is investigating “cool-burning” flames in space — a type of fire that burns at lower temperatures than ordinary flames on Earth. Blazes on this planet typically burn at between 2,240 degrees and 3,140 degrees Fahrenheit (1,225 degrees and 1,725 degrees Celsius). Cooler flames produced in microgravity burn at temperatures of between 440 degrees and 980 degrees Fahrenheit (227 degrees and 527 degrees Celsius).

In the space station experiments, researchers ignited droplets of heptane fuel. These types of fires are possible on Earth, but they are typically short-lived, flickering out almost immediately, the researchers said. In microgravity, though, the flames burned for several minutes. [7 Everyday Things that Happen Strangely In Space].
