  • VIDEO: What would happen if, instead of money, you get a black hole in your pocket?

    The big question: What would happen if, instead of money, you got a black hole in your pocket?

    In a Youtube video, the owners of the channel “Kurzgesagt – in a nutshell”, delivered a scientific explanation why a black hole, even the size of a coin, could cause the extinction of humanity and the planet Earth as well.

    What would happen to you if a black hole the size of a coin pops up in the proximity? The answer is grim: you will die. The question was developed in two particular cases: whether the black hole is with the mass of a coin, or as wide as a coin.

    In the first case, if a 5 gram coin transforms hypothetically into a black hole, then the black hole will have a radius about 10 times to the power of -30 meters. Despite the extremely tiny size, – a black hole compared to an atom appears to be as small as an atom compared to the Sun -, it will still posses a lot of energy as its 5 gram of mass can be converted into 450 terajoules of energy which can cause a blast 3 times bigger than the atomic bombs dropped on Hiroshima and Nagasaki combined. Therefore the conclusion is that a 5 gram black hole will kill you and many around you.

    It comes in a special square packet. best buy cialis Finpecia not only prevents hair from falling, but also improves the viagra professional for sale quality of erection for men during sex.

Due to the popularity of Kegel exercises products, most people buy greyandgrey.com cialis on line Kegelmaster in the UK in order to strengthen their pelvic floor muscles and tighten their vaginal muscles. In the second case, if the black hole has the diameter of a coin, then it will be considered consistently more massive. Actually, it will be slightly more massive than Earth. The gravity will be so high that it will tear individual atoms and cells apart. Hence, the black hole will consume everything around including the planet, so you stand no chance to survive.

  • Andrew Wiles awarded Abel Prize, aka Nobel Prize of Mathematics, for solving Fermat’s Last Theorem

    Briton Andrew J. Wiles, who cracked the mystery of Fermat’s Last Theorem in 1994, thus solving a problem that preoccupied specialists for more than 350 years, has been awarded the 2016 Abel Prize, often dubbed the “Nobel Prize for mathematics”

    The decision was announced on Tuesday by the Norwegian Academy of Science and Letters, which said that Wiles’ impressive proof opens “a new era in number theory”.

    The theorem in question bears the name of French mathematician Pierre de Fermat who wrote it on the edge of a page from a book, around 1637. He said back then that the theorem has a wonderful demonstration, but did not have enough space on that page to write it down.

    The stunning demonstration of Fermat’s last theorem is undoubtedly the peak of the career of Sir Andrew J. Wiles, born in 1953 in Cambridge, who graduated from Oxford and Cambridge Universities and continued his studies in the US and France.

  • Bermuda Triangle’s mysterious disappearances caused by giant craters, explained with methane bubbles “theory”

    Bermuda Triangle is one of the scariest places on Earth, as hundreds ships and airplanes would have disappeared without any explanation in the past 52 years.

    The Bermuda Triangle also known as the “Devil’s Triangle” is a roughly triangular-shaped area in the Atlantic Ocean delimited by Bermuda Island, Puero Rico and Fort Lauderdale, Florida.

    The recent discoveries of giant craters in the Barents Sea could be the explanation for the puzzling disappearances in the Bermuda Triangle.

    Scientists believe that the craters are the result of accumulation of methane gas. The explosion of such underwater gas bubbles causes huge openings that lead in turn to the formation of giant vortexes which would drag the ships and planes to the bottom of the ocean.

  • First Space Flower Blooms on Board ISS (PHOTO)

    A photo with the first flower that grew in Earth’s outer space was made public by NASA and posted to Twitter by Scott Kelly, an astronaut on the International Space Station (ISS).

    The ISS team had already succeeded in growing lettuce and now has reached a new milestone of their agronomic talent when edible Zinnia Elegans bloomed on board. It’s the first time when plants flourish outside the Earth’s atmosphere.

    “These plants are very fragile, so it was more complicated to grow,” says Trent Smith, manager of Veggie Project. The team feared several times that the ambitious efforts will fail.

    “It appears that our plants are not doing too well,” said Scott Kelly recently. “I need to awake Mark Watney (from the film ‘The Martian’), who sleeps in me,” he joked with a humor that accustomed his colleagues.

    While appearing insignificant for those on Earth, the bloom of the orange flower seems to be a big step for scientists, astronauts and future missions. Developing such crops in space could contribute to the organization of longer missions in space in more remote places, allowing NASA to learn more about the universe. “Yes, there are other life forms in space,” added Scott in his Twitter message.

  • Hydrogen bomb, most destructive weapon ever developed by humans

    The thermonuclear bomb a.k.a hydrogen bomb, the type of nuke that North Korea would have tested on Wednesday, was developed after the dreadful nuclear bombs were dropped in Japan at the end of the Second World War and is by far more destructive.

    A thermonuclear weapon contains hydrogen’s isotopes of deuterium and tritium which merge together delivering helium and high energy neutrons.

    While conventional nuclear weapons operate on the principle of nuclear fission, splitting the atomic nuclei rather than merging them, the hydrogen bomb uses an initial fission reaction, in order to produce a high temperature environment required for the occurrence of the stronger nuclear fusion reaction.

That is about 1,000 times stronger than the bomb dropped over Hiroshima in 1945.

    About a year and a half after the US tested the first full scale thermonuclear device, the Soviet Union developed its own H-bomb, thus launching a race to produce more ‘superbombs’.

    The most powerful hydrogen bomb ever detonated (also triggering the biggest explosion ever caused by humans) – was used by the Soviets in October 1961. Known as the Tsar Bomba, it had an explosive power equivalent to 50 megatons of TNT.

  • Four new chemical elements added to Mendeleev periodic table completing period seven

    The discovery of four super-heavy chemical elements by scientists from Russia, America and Japan has been verified by experts and they were formally added to the periodic table, informs The Guardian.

    Four new elements were placed in the Mendeleev’s table, thus completing its seventh row (period).

    The elements are the first to be added to the table since 2011 when elements 114 and 116 were inserted.

    The four newcomers were checked on December 30 by the International Union of Pure and Applied Chemistry (IUPAC), the global institution that governs measurements, nomenclature and terminology of chemistry.

    IUPAC has announced that a Russian-American team of scientists from the Joint Institute for Nuclear Research in Dubna and Lawrence Livermore National Laboratory in California, delivered sufficient evidence to claim the discovery of elements 115, 117 and 118.

    Overview : This webinar covers tips for when you have to work with someone who can give you good advice and who genuinely desires to assist you learn. sildenafil sales I tried all of these pills and what steps should you take to naturally generic viagra on line improve your health.

The body granted the credit to a team of scientists from the RIKEN Institute in Japan for the discovery of element 113, which had been also claimed by the Russians and Americans.

    Kosuke Morita, who leads the research at RIKEN, said that his team “is now looking to uncharted territory of element 119 and beyond it”.

    Ryoji Noyori, a Nobel laureate and former president of Riken said that “for scientists, the discovery has a higher value than an Olympic gold medal.”

    IUPAC has initiated the process of formalizing the names and symbols for these new chemical elements, provisionally termed ununtrium (UUT or element 113), ununpentium (UUP, element 115), ununseptium (Uus, element 117), and ununoctium (Uuo, element 118).

    The chemical elements will be officially named in the coming months by the teams of researchers who discovered them. Element 113 will be the first chemical to be named in Asia.
