A team of students from the National University of Singapore have created the first personal flying machine, called Snowstorm.
Snowstorm is an electric aircraft that can be raised and lowered vertically, and can be controlled by a person.
The vehicle, which looks like a giant drone, has place only for one person, and is equipped with 24 screw that are placed on a hexagonal skeleton. The giant drone has six wheels that help to lower to the ground. Electric vehicle can only fly for five minutes, and only indoors. He has a bad side that does not provide safeguards for the person who sits on it, so a crash could result fatal. Despite this, Snowstorm can serve as inspiration for others to develop personal aircraft that we can use in the real world.

Scientists believe they have proved Einstein's theory of general relativity. The scientist spoke a century ago for gravitational waves, whose existence was proved just now. Panel of scientists arrived at this conclusion while observing the alignment of time and space after the collision and merger of two black holes more than a billion light years from Earth. The group of international scientists says this is the first time that proved the existence of those that Einstein called "gravitational waves" that are changing the space-time extension depending on the reinforcement and fading field of gravity. The greater the gravity field is, the smaller is the space-time extension and vice versa, or under the principle of Einstein, "time flows more slowly where gravity is lower." The capture of gravitational waves is difficult because the signal arrives in poor soil, unless it is a gravitational activity "normal", but the collision of two black holes seems to have been the "talisman" of scientists. This is the first time that the universe speaks to us through gravitational waves. So far we were deaf, "said David Reitze excited, executive director of the LIGO project, engaged in research for years.
To understand the importance of intelligence suffices to note Danzmann Karsten comment, a German physicist and one of the most significant names in this field.
"This is the biggest discovery in physics since the discovery of the Higgs particle's. This invention is for a Nobel Prize, and is nothing to be discussed about it", he says.
Albert Einstein talked about the existence of gravitational waves almost 100 years ago. Einstein predicted that if gravity in an area of the universe changes abruptly as a result of an event of violent cosmic, like the explosion of a star, or in this case the collision of two black holes are created gravitational waves that spread at the speed of light in all universe, and in this process space and time are warped during their movement.
Gravitational waves were captured on September 14 last year, but the group of scientists decided to publish a report with its findings only now after consultation with a panel of 1,000 physicists and astronomers most prestigious in the world.

English physicist and cosmologist, Stephen Hawking, surprised the scientific community last week when he announced during a speech at Cambridge University where he actually believed that after the creation of the universe was a form of intelligence.
By introducing himself in front of the students at Cambridge University scientist world-famous Hawking said that his years of research on the creation of the cosmos have led it to set aside a factor of weird science which he says is in many ways at odds with the universal laws of physics.
This strange phenomenon which he calls "God factor", has been at the origin of the creation process and must have played a major role in determining the actual shape of the Universe. However, his previous statements have suggested that he did not believe in God. In his lecture, Hawking told his audience that if you find yourself trapped in a black hole, there is still hope for you. Perhaps one day the Creator will cause a change in the force of the black hole invaluable, and you will be release. In the end we have no reason not to believe that all this endless space where we live in, someone might be there, in any form, and that this may be our God. Is that an interesting news?

A brinicle (brine icicle, also known as ice stalactite) forms beneath sea ice when a flow of extremely cold, saline water is introduced to an area of ocean water, being the undersea equivalent of a hollow stalactite or icicle.
The formation of a brinicle was first filmed in 2011 by producer Kathryn Jeffs and cameramen Hugh Miller and Doug Anderson for the BBC series Frozen Planet.
Structure
At the time when a brinicle starts to created it resembles a pipe of ice reaching down from the underside of a layer of sea ice. Inside the pipe is the super cold, super saline water being produced by the growth of the sea ice above, accumulated through brine channels. At first, a brinicle is very fragile; its walls are thin and it is largely the constant flow of colder brine that sustains its growth and hinders its melt that would be caused by the contact with the less cold surrounding water. However, as ice accumulates and becomes thicker, the brinicle becomes more stable. A brinicle can, under the proper conditions, reach down to the sea floor. To do so, the flow of super cold brine from the pack ice overhead must continue, the surrounding water must be significantly less saline than the brine, the water cannot be very deep, the overhead sea ice pack must be still, and currents in the area must be minimal or still. If the surrounding water is too saline, its freezing point will be too low to create a significant amount of ice around the brine plume. If the water is too deep, the brinicle is likely to break free under its own weight before reaching the sea floor. If the icepack is mobile or currents too strong, strain will break the brinicle. Under the right conditions, including favorable ocean floor topography, a brine pool may be created. However, unlike brine pools created by cold seeps, brinicle brine pools are likely to be very transient as the brine supply will eventually cease.On reaching the sea floor, it will continue to accumulate ice as surrounding water freezes. The brine will travel along the sea floor in a down-slope direction until it reaches the lowest possible point, where it will pool. Any bottom-dwelling sea creatures, such as starfish or sea urchins can be caught in this expanding web of ice and be trapped, ultimately freezing to death.Source: Wikipeda

Other eyes see, other mind thinks. This video shows some of knowing illusions. There are explanation for all of them, so we know how they are made, and how they blow our mind, and look like that are another thing!

NASA is doing experiments about creation of Warp drive, that's enable make humans flying to other galaxies in a short period. Warp drive, is an spaceship that's move with a speed that exceeds light speed, this will be a revolution for humans, and will start a new era. If the Warp drive will use the negative energy can be possible to reach a speed that exceeds the light speed. White speculates that such a drive could result in speeds that could take a spacecraft to Alpha Centaur in a more two weeks even though the system is 4.3 light years away.

Earth is a big planet, there's space for 7 billion people out there, and available space for more billion of people! But let's look up in the sky and compare the size of earth with other planets and starts that are knowing by the humanity so far. It's amazing, and scary to see the size of them, by seeing the size of the biggest star, we have to see our planet on microscope. For our generations it's unimaginable pretending to explore one of these big stars, but one day maybe humanity can go at these stars, and why not one of them will shine their new planet! P.S They are planet and stars that humanity knows so far, because out there can be many more stars bigger than these.
