Supersonic speed is essentially a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C at sea level, this speed is approximately 1,125 ft/s, or 1,235 km/h. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.23. A vapor cone (above) is a visible cloud of condensed water which can sometimes form around an object moving at high speed through moist air, for example an aircraft flying at transonic speeds.

German teen Andrej Ciesielski traveled to Cairo, Egypt with the intent to rooftop - hang off the edge of - one of the three massive tombs at Giza. So, he scaled the 4,575-year-old wonder, and managed to captured incredible photos of the desert landscape, and risked 3-years in prison doing so. "It took me about eight minutes to get to the top of the pyramid and I listened to music on the way up. After a few minutes climbing, I started to attract a bit of attention and some of the security shouted to me to come down in Arabic. I had asked locals what they thought of my attempt and they warned me that it was illegal to climb the pyramids, although I thought it would be fine, what with Egypt's dependence on tourists. It was absolutely surreal standing on top of one of the wonders of the world and something that I will never forget. When I got back down, the police were quick to take me to the station and question me. They also had a look at my camera to see what I had been up to. At first, they wanted to take me to the German embassy, but after a while I was released without anything further happening," said Ciesielski. Click here to view more pictures of the crazy stunt.

NASA's newly released video provides viewers with a flight over the surface of dwarf planet Ceres, based on images from the Dawn spacecraft. It shows Ceres in enhanced color, which helps to highlight subtle differences in the appearance of surface materials, as well as showcasing the most prominent craters, such as Occator, and the tall, conical mountain Ahuna Mons. Dawn is the first mission to visit Ceres, the largest object in the main asteroid belt between Mars and Jupiter. The spacecraft is currently in its final and lowest mapping orbit, at approximately 240-miles from the surface. Click here to view the first image in this week's funny internet trolls gallery.

It's official, drone racing is now a real sport, starting with the Drone Racing League (DRL). These races take place in empty stadiums, abandoned malls, and old warehouses that have been equipped with bright neon checkpoints to steer the drones in the right direction, while dry ice fog is pumped in to create a mysterious atmosphere. For now, fans will have to settle for professionally edited race videos, but the league hopes to use live streaming video once the technology is available for drones.

Sector111 has just unveiled the Drakan Spyder, or basically a street legal go-kart. Unlike its smaller counterpart, this roadster / go-kart hybrid is powered by a Corvette-sourced LS3 V8 engine that generates 430-horsepower, mated to a Porsche G96 6-speed synchromesh transmission, enabling it to rocket from 0-60 mph in a mere 3.2-seconds. Continue reading for two more videos and information. Click here to view more pictures of the Drakan Spyder.
Liquid Glass Putty can stretch like rubber and bounce like a ball, and since it's silicone-based, the material won't dry out or crumble over time. Think of this as part toy, part stress reliever, part physical therapy and entirely addictive, or so the manufacturer thinks. However, pouring 500-pounds of this stuff into a bathtub and trying to climb out after the putty settles, is another story. Get some here now. Click here to view the first image in this week's art of trolling gallery. Continue reading for a viral video of a karate master destroying 726 bricks in 90-seconds.
Movies like Star Wars Force Awakens, Jurassic World, Interstellar, and countless others, all rely on VFX to immerse the audience. This interesting behind-the-scenes video shows us what the former looks like in green screen form, as well as post production. One interesting fact you may not have known is that Force Awakens uses more visual effects than Phantom Menace, which used tons of miniatures. Continue reading for three more behind-the-scenes videos.
Meiji University professor Kokichi Sugihara specializes in creating impossible illusions that seem to defy gravity, including these mind-boggling slopes that you see above. How is this possible? Technology of course, as he used a computer program to interprets two dimensional line drawings as three dimensional objects. "Sometimes the program turned these objects into real objects, and that's how I discovered that some impossible objects are not really impossible - they can actually be built as solids in three-dimensional space," said Sugihara. Continue reading for two more of his impossible illusions.
Forget watching movies on long international flights, soon passengers will be able to stare at the ceilings and walls of jumbo jets for a mesmerizing light show. Boeing has unveiled innovative projection systems that show celestial displays, clouds, mood lighting to entertain passengers (or help them fall asleep), and possibly even live streaming news, stock tickers, etc. For those who prefer personalized entertainment, the smaller displays will still be available, and loaded with movies, TV shows and more. Click here to view the first image in this week's geek life gallery. Continue reading for a video of the crazy omni-directional Infinadeck for gamers.
At first, it looks like a swarm of UFOs, but upon closer inspection, you'll see that it's actually LED-equipped UAVs. Intel put on a spectacular display at Flugplatz Ahrenlohe, Tornesch, Germany, of drone technology involving 100 small aircrafts being launched skywards in formation has earned a new world record title for the Most Unmanned Aerial Vehicles (UAVs) airborne simultaneously.
