Imagine building the tallest tower
|
view preview
Engineers led by sci-fi writer Neal Stephenson have unveiled plans for the tallest building in the world. Tall Tower would be 24 times the height of Dubai’s Burj Khalifa, considered the tallest building in the world, and would double the maximum heights for commercial airspace, as the designers believe the tower could also be used to launch rockets into space. A building this high poses many structural issues, and we don’t know if it will ever be built.

How much memory does our brain have?
|
view preview
While it's hard to calculate the memory capacity of the human brain, some estimates have put the number closer to 2.5 petabytes. But this is a great rough comparison.

Are the laws of physics the same everywhere on Earth?
|
view preview
The vortex is a spherical field of force, or a magnetic disturbance. The vortex is 165 feet in diameter and sits half way above ground and half below. The disturbance, or vortex causes unexplainable changes in perception, causing naturally occurring visual and perceptual phenomena that has been caught on film many times. Within the spherical distortion, people stand at an angle. The disturbance alters your relative gravity, causing you to stand at an angle of varying degrees. It is not possible for someone to stand vertical inside the vortex. It will also make someone who is walking away, seem taller, or shorter depending on where you stand. Balls roll uphill, brooms stand straight up and down on their own, and chairs appear to be held up b ...

The Verrückt: The world's biggest water slide
|
view preview
A water park in Kansas City is building a water slide, whose name aptly comes from the German word for "insane", that is over 164 feet tall. While nothing has been released about the speed of this slide, by our estimates, we'd say it'll be extremely terrifying.

Solar panels on the moon could one day power Earth
|
view preview
Architectural and engineering firm Shimizu plans to solve Earth's climate crisis by building a band of solar panels 400 kilometres wide along the entire 11,000-kilometre equator of the Moon. The energy generated will be beamed back to Earth in the form of microwaves and converted into electricity at ground stations. The team hopes to start building the "Luna Ring" from Moon materials in 2035.

A foot in a high stiletto. Can you see the tiny nails used to make the shoe? X-ray artist Hugh Turvey, who captured this image a few years ago, thinks the shoe looks like a torture device, what do you think?

World's first x-ray image of a human body part
|
view preview
Wilhelm Conrad Röentgen, a physics professor at the University of Wurburg in Germany, was experimenting with electric current flow in a partially evacuated glass tube in 1895 and one night he noticed a glow caused by an unknown radiation. He named the phenomenon x-radiation and few months later he took the first x-ray photograph of a body part: the bones in his wife’s hand – and one can even see her wedding band. The first even x-ray image was of a key.

On Venus it snows metal
|
view preview
At the very top of Venus’s mountains, below a thick layer of clouds, is snow. But not snow as we know it - with some surfaces reaching 480°C, Venus is way too hot for that. So what is this stuff? Researchers have figured out that Venus's heat is vaporising minerals called galena and bismuthinite, causing them to enter the atmosphere as a metallic mist before condensing into a shiny, metallic frost that rains down on the mountaintops.

This moon looks like a ball of cheese
|
view preview
The strangest moon in the Solar System is bright yellow. Taken by the Galileo spacecraft, this image shows Jupiter's moon, Io, and its incredibly bright colours derived from sulphur and molten silicate rock. Io is covered in volcanoes that are so active, they effectively turn the whole moon inside out. And some of Io's volcanic lava is so hot, it glows in the dark.

Did humans really step-foot on the moon?
|
view preview
This is not an illusion or some kind of sci-fi illustration. It's an actual laser beam, being shot at the eclipsed Moon on the 15 April 2014. The laser's target is the Apollo 15 retroreflector, which was left on the Moon by astronauts in 1971.

Earth-rise from the moon
|
view preview
This is a breathtaking 'earthrise' viewed from the surface of the moon. NASA's Lunar Reconnaissance Orbiter sees the Earth rise 12 times a day but is usually so busy imaging the moon's surface it doesn't get to capture the moment. This colourised image was taken on 1 February 2014.
