Spacetime invisibility cloaks can hide entire events inside temporal voids

--from internet (somewhere)

Invisibility cloaks are taking baby steps from science fiction to science fact. But there's an even stranger and more incredible possibility - an invisibility cloak that works in both space and time, shielding whole events from history itself.

The basic idea is surprisingly simple. We see things because our eyes are able to interpret information from visible light. That light travels at, obviously enough, the speed of light, which means we see things once light has traveled from them to our eyes. Technically speaking, we never see anything the exact instant happens - there's always a time lag between the object and when we see it.

This is fairly well-known for anyone with an interest in astronomy. The Moon is one light-second away, the Sun a little over eight light-minutes away, the nearest star 4.3 light-years away, the nearest galaxy , and so on. There are time lags on even everyday distances, however impossibly slight. For something a meter away, we see it as it was about 1/300,000,000th of a second ago.

Here's how you use that information to build a spacetime cloak. All those times are for the speed of light in a vacuum, but light can slow down depending on what material it passes through. Researchers have slowed down light to as little as 38 miles per hour by sending it through a special, super-dense form of matter. And it's through carefully slowing down and speeding up light that we can create a temporal void.

Let's say you're standing a mile away from an observer. You start slowly decreasing the speed of the light traveling towards the observer so that it's only traveling at 60 miles per hour, or a mile per minute. Since you're slowing the light down gradually, the observer won't be able to perceive the change. Once the light has reached 60 miles per hour, the observer is now seeing you as you were one minute ago. You've now created a one minute spacetime corridor. You've now got a minute to do whatever you want without the observer having any idea what you're up to.

Once your minute is up, you switch off the machine slowing down the light, it speeds back up, and the observer now sees you again as you are right now - or at least as you were a nanosecond ago. That minute is a temporally compressed blip that the observer cannot perceive. That a basic version of the idea put forward by researchers at Imperial College London. Here's their somewhat more technical explanation:

This process is thus utterly distinct from a spatial 'object' cloak, which instead achieves concealment by bending light around an object. The STC opens a temporary
corridor through which energy, information and matter can be manipulated or transported undetected. Once the concealed passage has been used, the STC closes by slowing the leading part of the light, whilst speeding up the trailing part, leaving no trace of the cloak, or the concealed events, on the field profile. To a distant observer, any non-emitting object whose presence persisted throughout the lifetime of the STC will have had a finite interval excised from its history. Any object which emits light during STC operation will have that part of its history temporally compressed so that, if not absorbed, it will appear to the observer as if occurring in a single instant.

This is quite possibly either the most awesome or the most dangerous idea ever, something the authors themselves admit when their first example of a potential application is a safe-cracker using such a cloak to rob a bank undetected. But can such a cloak be built? The researchers certainly think so, even if there are a mountain of technical challenges to navigate, and they foresee a race to create the first spacetime cloak. For now, the idea can just be an awesome new thing for science fiction writers to add to their repertoire...assuming any sane reader would ever be able to believe such a device could be possible.

Some of the World's unsolved mysteries.

Few stories have the power to captivate us more than those that remain unresolved. Codes, puzzles and cryptic public art tease us with their intrigue: Why is their message
coded? What great secrets might they hide? Despite the efforts of our most learned historians, cleverest cryptographers and most determined treasure hunters, history is replete with riddles that continue to confound us today. Fictional tales like those featured in “The Da Vinci Code” and the movie “National Treasure” have got nothing on these real-life puzzles. Here's our list of 10 of the world's most cryptic unsolved mysteries and codes.

Voynich Manuscript

Named after the Polish-American antiquarian bookseller Wilfrid M. Voynich, who acquired it in 1912,   the Voynich Manuscript   is a detailed 240-page book written in a language or script that is completely unknown. Its pages are also filled with colorful drawings of strange diagrams, odd events and plants that do not seem to match any known species, adding to the intrigue of the document and the difficulty of deciphering it. The original author of the manuscript remains unknown, but carbon dating has revealed that its pages were made sometime between 1404 and 1438. It has been called "the world's most mysterious manuscript."

Theories abound about the origin and nature of the manuscript. Some believe it was meant to be a pharmacopoeia, to address topics in medieval or early modern medicine. Many of the pictures of herbs and plants hint that it many have been some kind of textbook for an alchemist. The fact that many diagrams appear to be of astronomical origin, combined with the unidentifiable biological drawings, has even led some fanciful theorists to propose that the book may have an alien origin.

One thing most theorists agree on is that the book is unlikely to be a hoax, given the amount of time, money and detail that would have been required to make it.

Kryptos

Kryptos is a mysterious encrypted sculpture designed by artist Jim Sanborn which sits right outside the headquarters of the CIA in Langley, Va. It's so mysterious, in fact, that  not even the CIA has completely cracked the code.

The sculpture contains four inscriptions, and although three of them have been cracked, the fourth remains elusive (Read what the  first three inscriptions say here) ). In 2006 Sanborn let slip that there are clues in the first inscriptions to the last one, and in 2010 he released another clue: the Letters 64-69 NYPVTT in part 4 encode the text BERLIN.

Think you have what it takes to solve it?

Beale Ciphers

The  Beale Ciphers   are a set of three ciphertexts that supposedly reveal the location of one of the grandest buried treasures in U.S. history: thousands of pounds of gold, silver and jewels. The treasure was originally obtained by a mysterious man named Thomas Jefferson Beale in 1818 while prospecting in Colorado.

Of the three ciphertexts, only the second one has been cracked. Interestingly, the U.S. Declaration of Independence turned out to be the key — a curious fact given that Beale shares his name with the author of the Declaration of Independence.

The cracked text does reveal the county where the treasure was buried: Bedford County, Va., but its exact location is likely encrypted in one of the other uncracked ciphers. To this day, treasure hunters scour the Bedford County hillsides digging (often illegally) for the loot.

Phaistos Disc

The  mystery of the Phaistos Disc   is a story that sounds like something out of an Indiana Jones movie. Discovered by Italian archaeologist Luigi Pernier in 1908 in the Minoan palace-site of Phaistos, the disc is made of fired clay and contains mysterious symbols that may represent an unknown form of hieroglyphics. It is believed that it was designed sometime in the second millennium BC.

Some scholars believe that the hieroglyphs resemble symbols of Linear A and Linear B, scripts once used in ancient Crete. The only problem? Linear A also eludes decipherment.

Today the disc remains one of the most famous puzzles of archaeology.

Shugborough inscription

Look from afar at the 18th-century Shepherd's Monument in Staffordshire, England, and you might take it as nothing more than a sculpted re-creation of Nicolas Poussin's famous painting, “Arcadian Shepherds.” Look closer, though, and you'll notice a curious sequence of letters: DOUOSVAVVM — a code that has eluded decipherment for over 250 years.

Though the identity of the code carver remains a mystery, some have speculated that the code could be a clue left behind by the Knights of Templar about the whereabouts of the Holy Grail.

Many of the world's greatest minds have tried to crack the code and failed, including Charles Dickens and Charles Darwin.

Tamam Shud case

Considered to be one of Australia's most profound mysteries, the   Tamam Shud Case  revolves around an unidentified man found dead in December 1948 on Somerton beach in Adelaide, Australia. Aside from the fact that the man could never be identified, the mystery deepened after a tiny piece of paper with the words "Tamam Shud" was found in a hidden pocket sewn within the dead man's trousers. (It is also referred to as "Taman Shud.")

The phrase translates as "ended" or "finished" and is a phrase used on the last page of a collection of poems called “The Rubaiyat” of Omar Khayyam. Adding to the mystery, a copy of Khayyam's collection was later found that contained a scribbled code in it believed to have been left by the dead man himself.

Due to the content of the Khayyam poem, many have come to believe that the message may represent a suicide note of sorts, but it remains uncracked, as does the case.

The Wow! Signal

One summer night in 1977, Jerry Ehman, a volunteer for SETI, or the Search for Extraterrestrial Intelligence, may have become the first man ever to   receive an intentional message from an alien world.  Ehman was scanning radio waves from deep space, hoping to randomly come across a signal that bore the hallmarks of one that might be sent by intelligent aliens, when he saw his measurements spike.

The signal lasted for 72 seconds, the longest period of time it could possibly be measured by the array that Ehman was using. It was loud and appeared to have been transmitted from a place no human has gone before: in the constellation Sagittarius near a star called Tau Sagittarii, 120 light-years away.

Ehman wrote the words "Wow!" on the original printout of the signal, thus its title as the "Wow! Signal."

All attempts to locate the signal again have failed, leading to much controversy and mystery about its origins and its meaning.

Zodiac letters

The Zodiac letters are a   series of four encrypted messages   believed to have been written by the famous Zodiac Killer, a serial killer who terrorized residents of the San Francisco Bay Area in the late 1960s and early 1970s. The letters were likely written as a way to taunt journalists and police, and though one of the messages has been deciphered, the three others remain uncracked.

The identity of the Zodiac Killer also remains a mystery, though no Zodiac murders have been identified since 1970.

Georgia Guidestones

The   Georgia Guidestones,  sometimes referred to as the "American Stonehenge," is a granite monument erected in Elbert County, Ga., in 1979. The stones are engraved in eight languages — English, Spanish, Swahili, Hindi, Hebrew, Arabic, Chinese and Russian — each relaying 10 "new" commandments for "an Age of Reason." The stones also line up with certain astronomical features.

Though the monument contains no encrypted messages, its purpose and origin remain shrouded in mystery. They were commissioned by a man who has yet to be properly identified, who went by the pseudonym of R.C. Christian.

Of the 10 commandments, the first one is perhaps the most controversial: "Maintain humanity under 500,000,000 in perpetual balance with nature." Many have taken it to be a license to cull the human population down to the specified number, and critics of the stones have called for them to be destroyed. Some conspiracy theorists even believe they may have been designed by a "Luciferian secret society" calling for a new world order.

Rongorongo

Rongorongo is a system of   mysterious glyphs  discovered written on various artifacts on Easter Island. Many believe they represent a lost system of writing or proto-writing and could be one of just three or four independent inventions of writing in human history.

The glyphs remain undecipherable, and their true messages — which some believe could offer hints about the perplexing collapse of the statue-building Easter Island civilization — may be lost forever

The Egg : A stupid intelligent short story.

-written by Andy Weir.

You were on your way home when you died.

It was a car accident. Nothing particularly remarkable, but fatal nonetheless. You left behind a wife and two children. It was a painless death. The EMTs tried their best to save you, but to no avail. Your body was so utterly shattered you were better off, trust me.

And that’s when you met me.

“What… what happened?” You asked. “Where am I?”

“You died,” I said, matter-of-factly. No point in mincing words.

“There was a… a truck and it was very fast…”

“Yup,” I said.

“I… I died?”

“Yup. But don’t feel bad about it. Everyone dies,” I said.

You looked around. There was nothingness. Just you and me. “What is this place?” You asked. “Is this the afterlife?”

“More or less,” I said.

“Are you god?” You asked.

“Yup,” I replied. “I’m God.”

“My kids… my wife,” you said.

“What about them?”

“Will they be all right?”

“That’s what I like to see,” I said. “You just died and your main concern is for your family! That’s good stuff right there.”

You looked at me with fascination. To you, I didn’t look like God. I just looked like some man. Or possibly a woman. More of a grammar school teacher than the almighty.

“Don’t worry,” I said. “They’ll be fine. Your kids will remember you as perfect in every way. They didn’t have time to grow contempt for you. Your wife will cry on the outside, but will be secretly relieved. To be fair, your marriage was falling apart. If it’s any consolation, she’ll feel very guilty for feeling relieved.”

“Oh,” you said. “So what happens now? Do I go to heaven or hell or something?”

“Neither,” I said. “You’ll be reincarnated (punarjanma).”

“Ah,” you said. “So the Hindus were right,”

“All religions are right in their own way,” I said. “Walk with me.”

You followed along as we strode through the void. “Where are we going?”

“Nowhere in particular,” I said. “It’s just nice to walk while we talk.”

“So what’s the point, then?” You asked. “When I get reborn, I’ll just be a blank slate, right? A baby. So all my experiences and everything I did in this life won’t matter.”

“Not so!” I said. “You have within you all the knowledge and experiences of all your past lives. You just don’t remember them right now.”

I stopped walking and took you by the shoulders. “Your soul is more magnificent, beautiful, and gigantic than you can possibly imagine. A human mind can only contain a tiny fraction of what you are. It’s like sticking your finger in a glass of water to see if it’s hot or cold. You put a tiny part of yourself into the vessel, and when you bring it back out, you’ve gained all the experiences it had.

“You’ve been in a human for the last 48 years, so you haven’t stretched out yet and felt the rest of your immense consciousness. If we hung out here for long enough, you’d start remembering everything. But there’s no point to doing that between each life.”

“How many times have I been reincarnated, then?”

“Oh lots. Lots and lots. An in to lots of different lives.” I said. “This time around, you’ll be a Chinese peasant girl in 540 AD.”

“Wait, what?” You stammered. “You’re sending me back in time?”

“Well, I guess technically. Time, as you know it, only exists in your universe. Things are different where I come from.”

“Where you come from?” You said.

“Oh sure,” I explained “I come from somewhere. Somewhere else. And there are others like me. I know you’ll want to know what it’s like there, but honestly you wouldn’t understand.”

“Oh,” you said, a little let down. “But wait. If I get reincarnated to other places in time, I could have interacted with myself at some point.”

“Sure. Happens all the time. And with both lives only aware of their own lifespan you don’t even know it’s happening.”

“So what’s the point of it all?”

“Seriously?” I asked. “Seriously? You’re asking me for the meaning of life? Isn’t that a little stereotypical?”

“Well it’s a reasonable question,” you persisted.

I looked you in the eye. “The meaning of life, the reason I made this whole universe, is for you to mature.”

“You mean mankind? You want us to mature?”

“No, just you. I made this whole universe for you. With each new life you grow and mature and become a larger and greater intellect.”

“Just me? What about everyone else?”

“There is no one else,” I said. “In this universe, there’s just you and me.”

You stared blankly at me. “But all the people on earth…”

“All you. Different incarnations of you.”

“Wait. I’m everyone!?”

“Now you’re getting it,” I said, with a congratulatory slap on the back.

“I’m every human being who ever lived?”

“Or who will ever live, yes.”

“I’m Abraham Lincoln?”

“And you’re John Wilkes Booth, too,” I added.

“I’m Hitler?” You said, appalled.

“And you’re the millions he killed.”

“I’m Jesus?”

“And you’re everyone who followed him.”

You fell silent.

“Every time you victimized someone,” I said, “you were victimizing yourself. Every act of kindness you’ve done, you’ve done to yourself. Every happy and sad moment ever experienced by any human was, or will be, experienced by you.”

You thought for a long time.

“Why?” You asked me. “Why do all this?”

“Because someday, you will become like me. Because that’s what you are. You’re one of my kind. You’re my child.”

“Whoa,” you said, incredulous. “You mean I’m a god?”

“No. Not yet. You’re a fetus. You’re still growing. Once you’ve lived every human life throughout all time, you will have grown enough to be born.”

“So the whole universe,” you said, “it’s just…”

“An egg.” I answered. “Now it’s time for you to move on to your next life.”

And I sent you on your way.

Inspired by great Dynamic personality - Mr. Jay Vasavda

Being a part of V.V.P. Engineering College helps me in many ways .. for example having some deep impact making lectures under the banner -- "Swami Vivekananda's 150th Birth Anniversary".

Specially today, I think that it was worth for the real YOUTH. The really dynamic man with stunning thoughts came in our college to flame us - Mr. Jay Vasavda, a very famous columnist writes for "Gujarat Samachar", daily newspaper.

Definitely, he has touched many of the students and staff, like me.. He was perfectly right (by the way I am no one to certify HIM) saying "We are sleeping, although we know it and we don't want to wake up.. coz chalta hai.." kind of things. I think that we are used to this. The mentality of Indian people has gone worst now a days.. He, very sophisticatedly and sharply shot the target by saying that we have ignored the thoughts of Swamiji by ignoring many of his lines which pinches us. We only accept those which satisfies our EGO. Guys, its the fact that we have closed our eyes and ears, and accepted flawless sins in our blood and we also abuse the country, but stop mann !! Where is your contribution??

We hear many people saying that "WTH, we should not live in India.." why?? Basically a country is made up of people, and accept it that you are also one molecule of many which creates the nucleus of this uncontrollable Uranium.. I just want to say that everyone should start from their routine life, like, drive vehicle carefully, don't park it in no parking, stop spitting (urgghh..) , stop being involved in corruption, stay neat clean and DON'T make your surrounding unclean or dirty by throwing things, help the needful, share these kind of thoughts, educate or motivate others to get educated, understand your responsibilities my dear fellows.. Its not take and take until everything vanishes, to make any system stable, I think that it should be GIVE and TAKE to maintain the equilibrium. Perform your role..

To be very honest, we are becoming sheep. We are programmed to keep the body straight in NATIONAL ANTHEM , so we are doing it, but what's the purpose?? Have we lost the thinking power to think such things which defines us as Human? If it's true then I say, we really seek good PROGRAMMERS to run the sheep country which is filled also with blood thirsty  wolves.. who will save us? The PROGRAMMERS who will turn this sheeps into LIONS. Thanks a lot to Mr. Vasavda who inspired me to share my thoughts. Personally, I didn't give up, and won't.. infact I have just started.

Perhaps this post may make you feel bored , you can criticize me for my language, perhaps my poorly delivered thoughts, anyways.. whatever.. but..

I am ready to change the society. I STARTED. DID YOU?
