Stars at night time are pretty aren't they!!filled with light,although a lot of them can't be seen unless there is a clear sky free of smoke! nevertheless we see a lot of science friction going on in movies in novels,comics etc...but have u ever wondered when well can actually visit them in real life?hm... let's see.We have managed to put people on the moon and robots on asteroids,mars and even titan(a moon of Saturn).
But Inter-planetary travel is frickin cool but let's talk about interstellar travel um...as far as we know voyager -1 is expected to reach interstellar space time in this year or the next or the year after that.it was launched way before at 1977,Hm....now many say technology is developing rapidly so we will have the space travel thing in our life time or just after a few years ahead right??The nearest star we have next to the sun is proxima centauri it's just 4.24 light years away so it's a piece of cake huh?? actually it's a piece of difficult cake!!a light year means the time a light ray takes to travel from once place to another place for an year!and light is so fast that it could just circle the earth 7times in a sec
Helios space probe
The fastest man made object ever was helios 2 solar probe which travelled at a speed of 70,220m/s.Pretty impressive isn't it! although even at that speed it'd take 19,000 years to reach proxima centauri! which i don't think is a pretty less time
but hey technology is bound to be improved in the future!!we might make objects with even higher speeds.Just to not kill the dream of seeing stars let's see what we have at present.how about worm holes??Yeah just as we see in the movies we can warp right from here to a planet or a star some 10-12 light years away?it's not just a science friction they are theoretical but they could one day become a reality!.The question is how far away might that day be?
A scientist named Andrew kennedy did all the calculations about the travel velocities and earths technological growth and said that the soonest the human civilization would reach banard's star which is 6 light years away would take 1,104 years From today!let's be optimistic for a sec...we know that dinosaur's used to exist millions of years ago in earth right and died cuz of asteroid collosions?hm..why won't there be such things occuring to us in the future..i mean come on 1,104 years yeah there can be a chance,Tsunamis and global warming.There are even some theories saying that before we get the technology of interstellar travel we might perish due to some natural disaster!it may sound unlikely but by seeing all this the 2008 joint propulsion conference concluded that we would never visit any other places in space other than our solar system
In the end that crushes the dream and makes us come back to reality it does feel bad to know that these kind of beautiful things can only be seen in science friction or through telescopes.I guess that's the reason why they are so beautiful!!
The moon formed after the explosion of a runaway nuclear georeactor in the Earth's mantle, according to a new theory of lunar formation.
The standard theory of the origin of the Moon is called the giant impact hypothesis. It supposes that early in the Solar System's history, a massive object smashed into the Earth, cleaving it into two unequal parts. The smaller of these condensed into the Moon.
The best simulations of this process suggest that about 80 percent of Moon ought to have come from the impactor and 20 percent from the Earth.
That's hard to reconcile with the measured make up of Moon rock, which is almost identical to Earth rock in terms of isotopic content. Some planetary geologists say this could be explained if, soon after the impact, the debris mixed well before forming into solid bodies. But others counter that this might explain the similarity in the isotopic ratios of lighter elements such as oxygen but can't easily account for the identical ratio of heavier elements such as chromium, neodymium and tungsten.
But there's another theory called the fission hypothesis that could account for the similar isotopic content. This idea is that the Earth and Moon both formed from a rapidly spinning blob of molten rock. This blob was spinning so rapidly that the force of gravity only just overcame the centrifugal forces at work.
In this system, any slight kick would have ejected a small blob of molten rock into orbit. This blob eventually formed the Moon.
The fission hypothesis has been studied for 150 years but ultimately rejected because nobody has been able to work out where the energy could have come from to kick a lunar-sized blob into orbit.
Now Rob de Meijer at University of the Western Cape and Wim van Westrenen at VU University in Amsterdam say they know where that kick might have come from.
Their idea is that centrifugal forces would have concentrated heavier elements such as uranium and thorium near the Earth's surface on the equatorial plane. High concentrations of these radioactive elements can lead to nuclear chain reactions which can become supercritical if the concentrations are high enough.
The question is how concentrated could these elements have become. De Miejer and van Westrenen calculate that it is quite possible for the concentration to be high enough for a runaway nuclear reaction.
Their theory is that the explosion of a natural nuclear georeactor after it became supercritical ejected the material that eventually formed the Moon.
They also say that there ought to be telltale evidence that such an explosion took place, particularly in the lunar abundance of helium-3 and xenon -136, which would both have been produced in great quantities in a natural georeactor.
Future measurements from the surface could provide the evidence needed to confirm their theory but the analysis will not be easy. It is well known that the solar wind deposits vast amounts of these substances onto the lunar surface so that will have to be taken into account.
Of course, georeactors are by no means hypothetical. The most famous is in Oklo in Gabon, not so far from the equator, where a natural nuclear reactor was clearly in operation until about 1.5 billion years ago, leaving telltale signs in the uranium deposits now being mined!!
In an article in the Sunday Times, Norman Miller has stated that the conditions responsible for the mystery of the Bermuda Triangle ( which lies between the West Indies islands and the south-eastern coast of USA could provide the answer to the world’s energy crisis.
The energy source is methane gas and there are no alien spaceships or suburbs of Atlantis here. The myth of the Bermuda Triangle, the mysterious disappearances and strange events, has generated much interest all over the world through the years. Charles Berlitz’s book on the subject, published in 1974, sold nearly 20 million copies in 30 languages. Ships, boats, and even aeroplanes are all said to have disappeared in this area and all the mystery has been attributed to extraterrestrials. But scientists now have an explanation for these phenomena and the cause is not extraterrestrial but chemical. It goes by the name of methane gas hydrate, which is methane (created by decomposing organic debris) that has been entombed in an ice crystalline. Conditions are ideal for the formation of this gas in areas of permafrost. Another area is the deep sea floor where the pressure and the temperature are right for the creation of this gas.
It was only in 1981 that a geochemist, Richard McIver, went public on a link between methane gas blowouts and the Bermuda Triangle myth. He stated that massive landslides often occur along the North American continental shelf, which lies to the north of the Bermuda Triangle. Such land slumps can occur over a large area bringing down huge boulders which rupture the layer of gas hydrate beneath the sea floor, freeing the gas that is trapped beneath the hydrate ‘cap’ and also liberating huge amounts of methane trapped within the hydrate itself. The moment a methane gas pocket ruptures a vast reservoir of gas suddenly surges from the seabed, rising up in a huge plume before erupting on the surface within seconds and without warning. A ship caught in such a blowout would be doomed; the water beneath it would suddenly become much less dense, sinking it in a matter of moments. The vessel would plunge into the depths, where it would be covered as sediment disturbed by the blow out settles back on the sea floor. In fact, planes too could fall prey to such a deadly fallout.
The US geological Survey has estimated that just two small areas off the coasts of North and South Carolina, which are a part of the Bermuda Triangle, contain about 70 times the quantity of gas consumed annually in USA. The sea bed and the areas of permafrost are therefore storehouses of a great energy source. It has been estimated that just 1% of gas hydrate is equivalent to half the present conventional gas reserves. But the bad news is that methane is a greenhouse gas and it is vulnerable to blowouts when drillings go wrong. It is only stable under narrow temperature and pressure conditions and would decay due to global warming. We will have to wait and see whether it gives us energy to burn or it burns us up instead!
The Eastern State Penitentiary is a former state-prison in Philadelphia, Pennsylvania from 1829-1971. One of its most notable inmates was the notorious gangster Al Capone, who was incarcerated there in 1929 on illegal weapons possession. During his time at the penitentiary, Capone was supposedly tormented by the ghost of James Clark, one of the men murdered in the infamous St. Valentine’s Day Massacre.
Some descriptions of ghosts that haunt the area would be a shadow-like figure that scoots quickly away when approached, a figure in the guard tower, a evil cackling from cell-block 112, a shadowy figure in cell-block 6, and ghost faces appearing in cell-block 4.
There are tours that you can take of the penitentiary for a small fee if you are interested in experiencing the paranormal activity of the former jail. However, a lot of the locations listed in the previous paragraph are not permitted during the tour. Beware, Eastern State Penitentiary is widely considered one of the most haunted places in the world.
In 1754 along the Rappahannock River in Virginia, the London house was built. It was designed for the purposes as a full functional silk mill. In 1840, it was relocated to Urbana, Maryland where it became the Shirley Female Academy and then the Landon Military Academy and Institute. The basement was used as sleeping quarters for slaves. During the Civil War, General J.E.B. Stuart took possession of the mansion.
On September 8, 1862, the General initiated one of the most famous balls to ever take place during the Civil War. This went on to be called the Sabers and Roses Ball. The following day, he and his cavalry went on to fight in the Battle of Antietam, which turned out to be one of the most bloodiest days in American history. During the Civil War, the house served as a hospital for both Union and Confederate Soldiers. To this day, you can still see original sketches from the soldiers who stayed there. The house is currently on the National Register of Historic Places.
Staff members who work there and visitors to the site all have witnessed paranormal events. In 2003, a visitor witnessed the apparition of a Civil War Soldier. The person watched in shock as the ghost walked into the front door of the building, and walked up the steps and disappeared at the top of the landing. The basement of the house is believed to have a strong ghostly presence. Photo taken on the site reveal orbs, footsteps are heard with no one there, and temperature drops are frequent.
It's Probably one of the scariest and haunted places in the world!!!!
A SKELETON exhumed from a grave in Venice is being claimed as the first known example of the "vampires" widely referred to in contemporary documents.
MatteoBorrini of the University of Florence in Italy found the skeleton of a woman with a small brick in her mouth (see right) while excavating mass graves of plague victims from the Middle Ages on Lazzaretto Nuovo Island in Venice .
The above is the image of the woman's head found in the grave.
At the time the woman died, many people believed that the plague was spread by "vampires" which, rather than drinking people's blood, spread disease by chewing on their shrouds after dying. Grave-diggers put bricks in the mouths of suspected vampires to stop them doing this, Borrini says.
The belief in vampires probably arose because blood is sometimes expelled from the mouths of the dead, causing the shroud to sink inwards and tear. Borrini, who presented his findings at a meeting of the American Academy of Forensic Sciences in Denver, Colorado, last week, claims this might be the first such vampire to have been forensically examined. The skeleton was removed from a mass grave of victims of the Venetian plague of 1576.
However, Peer Moore-Janson says he has found similar skeletons in Poland and that while Borrini's finding is exciting, "claiming it as the first vampire is a little ridiculous".
Borrini says his study details the earliest grave to show archaeological "exorcism evidence against vampires".
How ever these people believe in the existence of vampires!!!!!!Do u?
Pretty much everyone wants to believe in the magnificent unicorn. They are one of the mythical creatures that seem to be loved on the collective whole. Robert vavra did a great job of convincing us all that they just might exist.
There is unicorn mythology from all corner's of the world, however, everyone has to make that call for themselves, even though most of us will continue to believe somewhere deep in our hearts. Perhaps that’s how they do exist, because so many people wish it to be true.
I’m not a total skeptic, but you’d think if someone found a real live unicorn skeleton there would be news about it somewhere.
The above picture is a real image it's not a fake!!! Atleast that's what the people say!!.
The horn on the nose is really what looks fishy, however if it isn't real it is a well done fake. hmm.....Many people agree with the existence of unicorn's . what do u believe in!!!(readers choice)
