There has been speculation of mysterious US aircraft that is capable of something very similar to alien technology. Even there is a patent over it.  TR-3B Black Manta or TR-3A or Astra is a highly classified black triangular aircraft that is explained like this in the patent: "A spacecraft having a triangular hull with vertical electrostatic line charger on each corner that produce a horizontal electric field parallel to the sides of the hull."   This patent is found on Google Patents with the inventor's name as John St. Clair. About the construction of aircraft has been explained as follows:  The triangular hull is in the form of complete equilateral triangle. There are two copper plates attached on opposite vertical sides at each of the three corners of the hull. In order to charge the copper plates corners to a high voltage, an electrostatic generator is use.  Beyond this, there has been claims that this spacecraft uses nuclear power to rotate highly pressurized ...

As you know, our earth completes a revolution every year and that's when we celebrate New Year. Likewise, there are cycles that affect out planet's long term climate condition.  Milankovitch Cycle was hypothesised by the Russian scientist Milutin Milankovitch 1920. In this, he said that the long term climate changes are affected by the change in Earth's relative position to the Sun. According to him, Eccentricity, Obliquity and Precession of the planet are the factors of this that change over long period of time. Ice ages are estimated to be because of this.  Eccentricity means the planet's orbit shape. This changes over time like increasing or decreasing. It has been found that it has been slowly decreasing over the period of the 100,000 years.  Obliquity is the tilting of planet over its axis of rotation. This normally results in changes of seasons. It is slowly decreasing over the span of 41,000 years. Precession is the wobbling of the planet over its rotating axis ...

Like the US has GPS (Global Positioning System), Europe has GNSS (Global Navigation Satellite System), Russia has GLONASS (GLObalnaya NAVigatsionnaya Sputnikovaya Sistema) and China has BeiDou Navigation Satellite System, India has its own satellite navigation system called NavIC (Navigation with Indian Constellation). These satellite systems enable Google Maps, Apple Maps etc. to come into play.  NavIC in hindi means sailor. Earlier, it was known as IRNSS (Indian Regional Navigation Satellite System). It has covering range of the entire Indian Subcontinent region which is above 1500 kms and can be extended beyond it unto 3000 kms. Currently, it uses satellite constellation of 7 and planned to be increased.  The requirement of NavIC was realized when the US denied request of GPS during Kargil war. Afterwards, this project got approval in 2006 and ISRO (Indian Space Research Organisation) began working on it.  NavIC has two usage. First is for SPS which stands for Standard...

In order to observe the universe, we need a telescope. But there is huge difference between a traditional telescope and a space telescope. A space telescope is able to observe things beyond imagination. In this article, we will explore about James Webb Space Telescope.  James Webb Space Telescope is largest telescope in space right now. It is built in collaboration of NASA (National Aeronautics and Space Administration), ESA (European Space Agency) and CSA (Canadian Space Agency). The purpose of James Webb Space Technology was to observe the formation of distant galaxies, exoplanets, discoveries related to formation of first stars etc. This telescope was launched on 25 December, 2021 where its destination was a solar orbit about 1.5 million kilometers from Earth.  This telescope is far different from our traditional telescope because it seeks out for near-infrared rays, orange and red light for observation. The telescope has 6.5 meter diameter gold coated beryllium primary mir...

On 22 October 2025, Google announced that they have solved a real world problem using their Quantum Echoes algorithm that did the work 13,000 times faster than current supercomputers.  This was the first time it has ever done where they used out of order time correlator OOTC algorithm. This  algorithm is verifiable since it can be ran again and again to get consistent result. They have released a scientific paper over this where they were able to do study of molecular structure using their latest Willow quantum computing chip. This chip used 105 qubit arrays to simulate the molecular behaviour. In this task, they disturbed one qubit from the simulated structure which lead to the formation of butterfly effect inside kind of like wave. This was first done in forward operations. After this, they ran the same operation but from the reverse side.  Both the sides waves start interacting with each other and give useful insights about the quantum nature.  According to Google...

What are XenoBots? Xenobots or you can say human made living lifeforms are the type of robot which are made of living tissues and cells to work at microscopic level for different purposes like drug delivery to specific part of the body, collecting microplastics in the oceans and seas to make a large blob, etc. These synthetic robots are made of skin cells and heart muscle cells derived from stem cells which are took from frog embryos. Here, skin cells works as protection shield for heart cells where heart cells drive the xenobots moving mechanism. The structure of the bots are designed in computer  simulation using evolutionary algorithms that uses trial and error method.  Xenobots are capable enough to move inside living bodies and have life of weeks. These bots are also able to heal themselves. Xenobots are able to work in swarm to execute large task to move some specific  material at microscopic levels. They have ability to self replicate new xenobots with same featur...

Titan is the largest moon of Saturn out of 274 known moons and only moon to have a dense atmosphere of the entire solar system known so far. This moon is so much big that it is larger than the Mercury planet. It was discovered in 1655 by Christiaan Huygens, A Dutch Astronomer, and it was the first moon of Saturn to be discovered. Saturni Luna was the name given by him. Also, it is the second largest moon in the Solar System after Ganymede, Largest Moon of Jupiter. It is also the tenth largest body in the entire solar system so far. Titan is composed of ice and rocky materials. It has liquid water rich in ammonia which has potential of life forms. The atmosphere of Titan comprises mainly of nitrogen and methane. Its climate is capable of rain and wind which further leads to the creation of rivers, lakes, ponds, seas, deltas, dunes etc. It has methane rain cycle somewhat similar to Earth's water rain cycle. Titan is basically the most similar celestial body in the Solar System. It ha...
