Thursday 11 February 2016 16:30, a historic moment for Science took place, in the first official statement by the detection of gravitational waves on Earth. Albert Einstein described the existence of these waves in June 1916, that is, 100 years earlier, as a consequence of the theory of general relativity published in 1915. at that time, It was impossible to visualize this phenomenon with existing technology.

Indeed, the gravitational waves are distortions of space-time that have infinitesimal impact on Earth, and could identify only with huge amplifiers and detectors such as LIGO Observatory in the USA, or the GEO 600 detector-in Germany. But how it all started; Over a billion years ago, in a distant galaxy, merged two giant black holes. This cosmic conflict shook the fabric of spacetime, spreading the energy around three Suns in the form of gravitational waves that are sent to the edge of the universe at the speed of light.

On September 14, these waves reached Earth. On Wednesday, February 10, 2016, the Executive Director of the LIGO Observatory, David Reitze, announced that it has identified for the first time these gravity waves, but this was not known until the next day at an official press conference led by scientists from Caltech, the MIT and the LIGO. This observation confirms the hypothesis put forward by Einstein in his theory of general relativity.

Tourists in space On Sunday, July 11, 2021, billionaire Richard Branson, accompanied by three other passengers and two pilots, made his first trip into space with virgin galactic company's VSS Unity spacecraft, thus starting space tourism. The aircraft took off from the runway at Spaceport America Base in New Mexico, climbing to an altitude of about 15 km before the landing of the spacecraft. VSS Unity then ignitioned its engine and started an ultrasonic ascent, reaching an altitude of over 80 km., A height defined in the United States as the 'frontier' of space (100 km to other countries). As soon as the engine was off, passengers were able to get out of their seats, to navigate gravity and observe the Earth from space.
How gravity makes falling objects; As Einstein said, gravity is not simply the attraction of the US Land, but a warping of spacetime. But this is not very easy to understand. The Current us Edward explains it as simple as possible, with a device that he constructed himself.
The moment TV channels switched to color image Snapshots from the moment TV channels changed their image from black and white to color. Each channel celebrated the event in its own way. In order, there is Norway in 1972, the United States in 1958, Germany in 1967, Australia in 1975 and France in 1967.
Fan powered by a kerosene lamp A fan made by the Carl Jost company in the 1910s in Zeitz, Germany. This fan is powered by a kerosene lamp and uses a hot air motor to move its blades, instead of relying on electricity.
Robbery with a bad ending… for the robber In the Buckhead area of Atlanta in the United States, a man in a hat and sunglasses walked into a nail salon shouting "Everyone down! Give me your money!" But bystanders did not react and the man left after 30 seconds stealing a mobile phone.
Gravity won Accident trying to load a refrigerator onto a truck, by two men. The incident occurred on November 29, 2022 in South Carolina, USA.
The DART spacecraft crashes into asteroid to change its trajectory After 10 months of space travel, the DART probe hit its target by dropping more than 20.000 km/h in the asteroid Dimorphos located about 11 million kilometers from Earth. The purpose of the mission was to deflect the orbit of the asteroid in order to protect us from an asteroid heading towards our planet. The images were captured by the probe before impact with the approximately 160-meter-diameter asteroid. It will take a few weeks for scientists to confirm that the asteroid has indeed deviated from its orbit.
Because in some areas of the Earth it does not get dark In some areas of the Earth during the summer, the Sun remains visible for over 24 hours or even months without getting dark. This phenomenon is called "Midnight sun" and is observed at latitudes above the Arctic Circle and below the Antarctic Circle. The phenomenon is due to the inclination of the vertical axis of the Earth by 23 ° 26΄ in relation to its plane of rotation around the Sun.. Its duration depends on the latitude, from which we observe it. The closer the observer is to the north or south pole, the longer it lasts. For example, the sun shines continuously for 6 months on the poles, while in the northern tip of Finland it is limited to 73 days. The opposite phenomenon, where the night lasts for more than 24 hours during the winter, it is called "Polar Night".

Acceleration 0-264 km / h on a Tesla Model 3 On the Autobahn motorway in Germany, a driver tests the acceleration of the Tesla Model 3, reaching 254 km / h. The screen is set to mode "track" to indicate a possible increase in battery temperature. The graph on the right shows the power consumption.
Man on ATV with his dog vs train A man driving an ATV and pulling his dog by the leash, decides to cross a level crossing with the bars lowered, while a train is approaching at speed. A reckless act that could be deadly. The incident happened in the city of Troy, in Montana in the United States.

How to properly organize your nails Based on intuition, one can think that this is a video that plays In reverse, but this is not the case. When energy is added to the system shaking the bucket, nails begin to act like a liquid, filling the natural shape provided in their container. Since they don't receive enough energy to flee in all directions, frictional forces and weight decrease the energy of the system, bringing it to a lower power state and higher entropy, which is their arrangement within the container.
Can a dead fish swim; A team of researchers from MIT and Harvard were surprised when accidentally discovered this phenomenon. They are studying how a live trout preserves its energy by swimming behind barriers against water stream, and unwittingly placed a dead fish in the experimental setup. The fish was moving against the tide that pushed backwards, making slow progress until they reached the barrier and pushed back the influence of power. Researchers found nothing special in this, until they realized that the fish were already dead. as evidenced, Objects that block the natural flow of water, such as a rock or a boat, creating a series of complex turbines in power as the water is directed after the obstacle. In some cases, the turbine array formed behind a barrier forcing the body and tail of the fish coming in coordination. This tilts the body in such a way that the vortices, causing pressure drop, to apply a suction force that propels the fish forward. This is the way in which fish save energy, and with a little push from their bodies, proceed or stop.
Amusement park game in the shape of swastikas (Germany) On Friday August 16, 2019, Tatzmania the amusement park in Löffingen, Germany was forced to close one of the games of the name "Eagle Fly" A few weeks after its launch in late July. The reason; Guests complained that the arms form two swastikas. Ο Rüdiger Brown, director of the park, He stated that it went nothing like this in his mind and apologized later "anyone felt embarrassed or offended" the shape of the carousel.
