A Canadian Company Just Got A U.S. Patent for This Giant Inflatable Space Elevator

Thanks to forces like gravity and air resistance, getting a rocket out of our atmosphere is a difficult and costly endeavor. Depending on its size and weight, space agencies like NASA can spend anywhere from $100 million to $260 million to launch a cargo ship into space. But what if we could build a giant tower that reached all the way up into space — a tower capable of shuttling supplies and even people from the surface of the earth

52 International Skydivers Break “Head Up” Formation World Record (Video)

As if skydiving wasn’t intense enough, last year an international group of 52 skydivers set a new world record for the “head up” skydiving formation. According to Business Insider… “An amazing video has emerged of 52 skydivers setting a new world record for a ‘Head Up’ flight formation over Phoenix, AZ, US. The footage is shot by participant Zachary R. Sabel using a helmet-mounted camera.”   The stunt was certainly impressive, using three different planes to carry skydivers from countries like

Scientists Just Captured What Thunder Looks Like for the First Time Ever (Video)

A pair of scientists from the Southwest Research Insitute in San Antonio just became the first people to successfully image a thunderclap. Their research was presented at a geophysics conference in Montreal on Tuesday (May 5). Lightning and thunder are extremely unpredictable. While we obviously have the capability to track thunderstorms, it is virtually impossible to predict exactly when and where an individual lightning strike will occur. To get around this issue, scientists Maher Dayeh and Neal Evans created their own lightning by using

New Terminator-Inspired Method Makes 3D Printing 25-100 Times Faster (Video)

In the climax of the movie “Terminator 2”, the Terminator’s arch-nemesis — the evil T-1000 — is melted down into a puddle of metallic goo. Unfortunately for Arnold and company, the robot re-emerges seconds later, rising fully-formed from the puddle of molten metal. It was this scene that inspired a group of scientists at a company called Carbon3D to completely rethink our current methods of 3D printing. The company, which had been keeping the project a secret during the past two years of development, revealed their new method in

Antarctica Is Melting So Fast That It’s Altering Earth’s Gravity (Animation)

The strength of Earth’s gravity varies depending on where you are, mostly because of differences in the composition (ie. densities) of different regions on Earth. In 2009, the European Space Agency launched a satellite called the Gravity field and steady-state Ocean Circulation Explorer (GOCE), with the purpose of mapping these variations and seeing how they changed over time. During its four year period, the satellite gathered a lot of interesting and useful data, including this “gravity scar” left behind by the

Scientists Just Created A New Material- A Spoonful Can Suck Up All the Oxygen In A Room

Scientists from the Department of Physics, Chemistry and Pharmacy at the University of Southern Denmark have created oxygen-absorbent crystals that can easily and conveniently store and release oxygen at high concentrations. Although humans require oxygen to survive, the air we breath is only 21% oxygen, the other 79% being comprised almost entirely of nitrogen. However, there are plenty of instances where it’s necessary to have oxygen available in considerably higher concentrations, such as lung patients with oxygen machines and fuel

This Picture of the Moon Is the First Photo Taken By A New 3-D Printed Telescope

3-D printing technology has been improving in leaps and bounds lately, and now it can add yet another cool accomplishment to its resumé: taking a picture of the moon. It all started with a team of astronomers at the University of Sheffield in England who wanted to see if they could design their own high-powered telescope rather than paying thousands of dollars for one. Using only 3-D printer and a Raspberry Pi camera module, the team was able to create a telescope capable

The Physics Behind Why Cats Always Land On Their Feet (Video)

Almost everyone knows that cats have an extraordinary ability to land on their feet, even if they start out upside down. But how are they actually able to do this? Destin, founder of the popular youtube channel SmarterEveryDay, recently broke down the science behind how cats are seemingly able to always land on their feet. He posed the following question: How does a cat go from feet up to feet down in a falling reference frame without violating the conservation of angular momentum?

Forget Everything You Thought You Knew About “Horsepower”

Every time the newest model of truck or car comes out, the car manufacturers loves to tell you how much “horsepower” the vehicle has, conjuring up visions of muscular stallions galloping through the countryside. But I put the term “horsepower” in quotes because these visions are misleading. See, in our modern world, horsepower is simply a scientific unit that we accept as a standard. But to understand what it actually means, you have to understand where it actually comes from. The

A 3-D Printed Robot Flying A Prototype for a Quadcopter Hoverbike (Video)

Back in May, I wrote an article about a futuristic new hoverbike called the Aero-X set to go on sale in 2017. Now it seems that the Aero-X may have some serious competition. A company called Malloy Aeronautics recently completely a successful Kickstarter campaign for a similar hoverbike that uses four helicopter bladed instead of two, adding additional control, stability and maneuverability to the craft. Though they haven’t yet built a full-size model, Malloy Aeronautics has built a 1/3 scale model that they’re
