WORMHOLES

WORM HOLE ARE TIME TRAVELING MACHINES

A wormhole is a sort of tunnel that joins distant points in space, or even two universes, via space-time curvature. Theoretically, such a tunnel could be traversed from one point in space to another without actually traveling the distance between them.




 In the 1980's, Thorne, who is the Feynman
Professor of Theoretical Physics, Emeritus, at the California institute of Technology, kicked off a serious discussion among physicists about whether or not an object (like a spaceship) could physically travel through a wormhole. In other words, do the laws of physics forbid it? Or, with unlimited resources and knowledge, could a civilization build a wormhole ?

Physicists, including Thorne, have made some progress on this question. Scientists knew prior to the 1980s that if wormholes existed, they would evaporate before anything (even light) could pass from one opening to another. So sending something through a wormhole would require a kind of scaffolding made from "exotic matter" to hold the wormhole open.
In addition, wormholes for travel would likely need to be artificially constructed, because there is no solid evidence that they exist naturally.
Wormholes can be path for future and past, but it's too tough to create a artificial wormhole.
Some scientists suggested that black hole and white hole worked as a worm hole for passage of matter and energy from one universe to another.
Here are some theories and laws which can create worm hole.

CASIMIR EFFECT

The Casimir effect is a small attractive force that acts between two close parallel uncharged conducting plates. It is due to quantum vacuum fluctuations of the electromagnetic field. The effect was predicted by the Dutch physicist Hendrick Casimir in 1948.
The Casimir effect shows that quantum field theory allows the energy density in certain regions of space to be negative relative to the ordinary vacuum energy, and it has been shown theoretically that quantum field theory allows states where the energy can be arbitrarily negative at a given point.

V616-MONOCEROTIS —NEAREST BLACKHOLE TO THE EARTH

Image
V616 MONOCEROTIS —  THE  NEAREST  BLACK  HOLE  TO  EARTH MILKY WAY  has millions of black hole. Our galaxy has super massive black hole at it's center  SAGGARITUS A which is too much powerful, but it is too far from earth.Black holes are destroyer. They engulf everything which is full of matter. Then question arises is there any danger to earth from any black hole?  As per observations V616 MONOCEROTIS is the closest known black hole from earth.  It is also known as A0620-00. This system is binary star in MONOCEROUS constellation.  This constellation only contains two objects.  SIZE   = APPROX (LONDON CITY)  DISTANCE FROM EARTH -   3457  light years MASS OF A0620-00 =   6 TO 9  TIMES OF SUN The black hole in A0620-00 pulls matter from the K-type star into an accretion disk.  The accretion disk emits significant amounts of visible light and X-rays. Because the K-type star has been pulled into an  elliptical  shape, the amount of surface area visible, and th

THE STAR BAFFLED SCIENTISTS WHICH LOOKS OLDER THAN OUR UNIVERSE  The age of our universe is 13.8 billion years. Scientists found a star who baffled them by it's age. Scientists have discovered star whose age is 14.5billion years. Now question is can our universe have stars older than itself?  This is condrum that universe is younger than its some stars.  HD 140283 : HD 140283, informally nicknamed the Methuselah star, is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, specifically toward Ophiuchus. Its apparent magnitude is 7.205.   It's a riddle of cosmic proportions: how can the universe contain stars older than itself?" physicist Robert Matthews  wrote for  The National ,  an English-language newspaper published in UAE. It could spark on new scientific revolution.  Dr Matthews, a member of the UK's Royal Astronomical Society, said recent measurements of the cosmic background radiation left over a

PULSARS

PULSARS PULSARS are highly magnetized neutron star which is rotating at high speed . It is White dwarf or neutron star which emits electromagnetic radiation. Pulsars have strong magnetic field which funnels jet out particles in form of radiation. This radiation can be detected only if radiation points towards earth. This particles create a beam of light. Three distinct classes of pulsars are currently known , according to the source of the power of the electromagnetic radiation: 1. Rotation-powered pulsars , where the loss of rotational energy of the star provides the power, 2.Acceration power pulsars where gravitational potential energy of accerated matter is power source.  3.Magnstars where decay of electromagnetic field of pulsar provide power.  APPLICATIONS:                                     pulsar are used to find unobservable celestial object known as neutron star which rotates near to speed of light.   Milliseconds pulsar allowed to test        G
