Big Crunch

One of the most important and proportional hypothesis of the ultimate fate of several other universes is the Big Crunch. The Big Crunch involves metric expansion of space eventually reverses and the universe re-collapses, ultimately ending as a black hole singularity or causing a reformation of the universe starting with another big bang, which has been agreed by many cosmologists as well as astrophysicists. Ultimate fate of universe is often treated as a subject with relative conflict of interests. This term involves equal numbers to agree and disagree upon. First up, we know the Big Bang theory is a cosmological model for the universe that accounts for the fact, the universe expanded from a very high density and high temperature state, and offers a comprehensive explanation for a broad range of phenomena, including the abundance of light elements, the cosmic microwave background, large scale structure and Hubble's Law (1. Objects observed in deep space are found to have a Doppl…

Will Earth Survive?

What will happen to the Sun 5 billion years from now, and how will it impact the planets in our Solar System, specifically Earth?
To answer that, a team of astronomers from Belgium have set their sights on a distant star called L2 Puppis, which lies 208 light-years away and provides an accurate depiction of what might happen when our Sun turns into a red giant.
The team of astronomers from the University of Leuven in Belgium is using a star that – 5 billion years ago – could have been the Sun’s twin, to witness our Solar System’s future. And it's not looking great.
"We discovered that L2 Puppis is about 10 billion years old," said team member Ward Homan.
"Five billion years ago, the star was an almost perfect twin of our Sun as it is today, with the same mass. One-third of this mass was lost during the evolution of the star. The same [thing] will happen with our Sun in the very distant future."
To pull this observation off, the team used the European Southern …

Superconductivity- A New Theory

An  international team of scientists have announced the discovery of new state of matter in a material that appears to be an insulator, superconductor, meta and magnet combined together, that could lead to the development of more effective high-temperature superconductors. Why does this attract each of our attention? Practical energy production involves materials and resources that usually gets worn out at higher temperatures, resulting in retreat of all the steps taken ahead. Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic flux fields occurring in certain materials when cooled below characteristic temperature. The electrical resistance of a metallic conductor decreases gradually as temperature is lowered. An electric current flowing through a loop of superconducting wire can persist indefinitely with no power source. This quantum mechanical phenomenon is characterized by Meissner effect that states, the complete ejection of magnetic …

Acoustic Metamaterials

Limitations set by men, are often broken by the same set. To know more than what we have been provided with is what we need and work upon. Our world of science has taken us to a place far enough to engineer materials have properties different from its default nature. Metamaterials are materials engineered to satisfy the statement above. They derive their properties from their newly designed structures, such as their precise shape, geometry, size and orientation gives them their smart properties capable of manipulating electromagnetic waves; by blocking, absorbing, enhancing or bending waves, to attain profit over a large scale which the conventional materials fail to provide. Metamaterials have opened doors to many ideologies and theories that involve headline hitting discoveries. They consist of composite materials with small inclusions and/or intricate structuring that can average out over a wavelength. There are various types of metamaterials over changing their primary properties …

Baba Vanga

Grandmother Vanga was a blind bulgarian mystic, clairvoyant, and herbalist, who spent most of her life in the Rupite area in the Kozhuh mountains, Bulgaria. Millions of people around the world were convinced that she possessed paranormal abilities. In her childhood, Vanga was an ordinary child with brown eyes and blonde hair. She grew up in poverty after her mother's demise. Vanga was considered intelligent for her age. Her inclinations started to show up when she herself thought out games and loved playing "healing" - she prescribed some herbs to her friends, who pretended to be ill. A turning point in her life was a tornado lifted Vanga up and threw her in a nearby field (this claim has not been verified with meteorological records from that time). She was found after a long search. Witnesses described her as very frightened, and  her eyes were covered with sand and dust, she was unable to open them because of the pain. There was money only for partial operation to he…

9/11 Conspiracies(Part-2)

These theories attribute to the planning and execution of the September 11,2001, attacks against the United States to parties other than,or in addition to , al-Qaeda including that there was advance knowledge of the attacks among high-level government officials. Government investigations and independent reviews have found no evidence for the theories. Proponents of these theories claim there are inconsistencies in the official conclusions, or evidence that was either ignored or overlooked. The most prominent conspiracy theory is that the collapse of the Twin towers and 7 World Trade Center were the result of a controlled demolition rather than structural failure due to impact and fire. Another prominent belief is that the Pentagon was hit by a missile launched by elements from inside the U.S. government or that a commercial airliner was allowed to do so via an effective stand-down of the American military. Possible motives claimed by conspiracy theorists for such actions include just…
