Time in Indian philosophy is an Attribute of Reality, so is Space.
The Cyclic Theory of Time overcomes the Non Linear Theory of Time in that there is no seeming contradiction in comprehending different time scales.
to illustrate,; you take a snap of an action, say a cricket match with two different cameras, one with a higher speed and another with ultra slow speed.
If a catch has been under dispute, the ultra slow motion camera will show the exact action, that is, whether the catch has been taken cleanly by the fielder.
One camera shows an action and another does not show it.
Which is True in relation to Time?
That is to say, one instrument recording the event for the same period does not show it, though it should have passed the time at which the event has taken place and the other shows the same event, which it has passed.
Recordings provide us with two projections.
Ordinary Daily events we see are recorded here in Ultra Slow motion and In Fast Mode.
Which ‘Seeing is Correct?’
What do we See?
If it is due to the quality of instrument, then can we not say each one of them is correct or both of them are wrong?
So when we talk about Perception, Time factor is one of the coordinates we do not know much about, if we accept Linear Theory.
If we accept Cyclic Theory, we can say the event has happened and not happened.
The difference is the relative positioning.
Again, an event is a form of energy.
Energy can neither be created nor destroyed.
If we accept the Theory of Linear Time, we have to say the event is no more or is destroyed.
Under Cyclic Theory, this does not happen as everything happens, happened and will happen at the same time.
Recent researches on Human Brain have shown that the Brain anticipates action yet to take place and keeps the senses like eyes to receive the message and in fact receives (ref. TOI Aug 08) the message ahead of the event.
Time moves both forwards and backwards .Time is a Stream; so is Space. Per se they are Absolute. They are Relative to the observer.
To put it in simpler words ,things exist in Space and Time at all times irrespective of your positioning and what we say to-day has happened ,is now happening at another level for an observer positioned to observe it.
For them, our Universe is Past. Similarly for another observer, what we see as future, may be Present.
**
If we accept the Linear Theory of Time, we can not account for the time factor.
(This leaves an interesting question. Do we really see what we see?
Do we prove the existence of eyes because the scenes are seen or do we see things because we have eyes?)
We will be able to Realize Self when we transcend Space and Time.
China is better in that it goes about doing things openly unconcerned about criticism of the so-called World Opinion,read US.
Story:
“Truth” appears to have vanished from the Chinese internet, after micro-bloggers discovered the word had been blocked on the country’s leading social-media website.
Online messages began circulating earlier this week claiming that the Chinese characters for “the truth” could not be searched for on the Twitter-like micro-blog, Sina Weibo, which boasts nearly 300 million registered users.
Attempts to search Weibo for “the truth” on Thursday turned up the message: “According to relevant laws, regulations and policies, search results for ‘the truth’ cannot be displayed.”
It is not known how long the term has been blocked or why but one internet-user said they had first noticed the truth was missing in late June. Sina Weibo did not respond to requests for information.
Qi Zhenyu, head of social media for iSun Affairs, a Hong Kong-based current affairs magazine, said it was not clear when censors might allow the truth to return.
“It is not unusual but it is quite ironic this time – you can’t simply block the truth,” said Mr Qi, one of the first to detect truth’s absence.
China is notorious for actively blocking sites such as Facebook and Twitter with its Great Firewall. But social media firms are also required to self-censor as a result of government guidelines and pressure.
Terms blocked in the past include those deemed obscene as well as politically sensitive ones such as “Tiananmen Square” or the name of disgraced politician “Bo Xilai“, whose wife was implicated in the suspected murder of British businessman Neil Heywood.
“Weibo is the most popular social media site in China and as a result suffers the highest level of censorship,” said Mr Qi, whose online magazine is also blocked in mainland China.
“Whenever there is a word that upsets them, they just go ahead and block [but] most of the time you can’t really explain why they censor a certain word.”

Past Universe with Microwave background.
”
Stephen Hawking has said: “We should look for evidence of a collision with another universe in our distant Past.” Some experts believe that what we call the universe may only be one of many. Is there any conceivable way that we could ever detect and study other universes if they exist? Is it even falsifiable?
This was a key question Hawking was was asked in an interview with the BBC. “Our best bet for a theory of everything is M-theory –an extension of string theory,” Hawking continued. “One prediction of M-theory is that there are many different universes, with different values for the physical constants. This might explain why the physical constants we measure seem fine-tuned to the values required for life to exist.”It is no surprise that we observe the physical constants to be finely-tuned. If they weren’t, we wouldn’t be here to observe them. One way of testing the theory that we may be one of many universes would be to look for features in the cosmic microwave background radiation (CMB) which would indicate the collision of another universe with ours in the distant past.The circular patterns within the cosmic microwave background shown above suggest that space and time did not come into being at the Big Bang but that our universe in fact continually cycles through a series of “aeons,” according to University of Oxford theoretical physicist Roger Penrose, who says that data collected by NASA’s WMAP satellite supports his idea of “conformal cyclic cosmology”.
Penrose made the sensational claim that he had glimpsed a signal originating from before the Big Bang working with Vahe Gurzadyn of the Yerevan Physics Institute in Armenia. Penrose came to this conclusion after analyzing maps from the Wilkinson Anisotropy Probe.
These maps reveal the cosmic microwave background, believed to have been created just 300,000 years after the Big Bang and offering clues to the conditions at that time. Penrose’s finding runs directly counter to the widely accepted inflationary model of cosmology which states that the universe started from a point of infinite density known as the Big Bang about 13.7 billion years ago, expanded extremely rapidly for a fraction of a second and has continued to expand much more slowly ever since, during which time stars, planets and ultimately humans have emerged.
That expansion is now believed to be accelerating due to a scientific X factor called dark energy and is expected to result in a cold, uniform, featureless universe. Penrose, however, reportsPhysics World, takes issue with the inflationary picture “and in particular believes it cannot account for the very low entropy state in which the universe was believed to have been born – an extremely high degree of order that made complex matter possible. He does not believe that space and time came into existence at the moment of the Big Bang but that the Big Bang was in fact just one in a series of many, with each big bang marking the start of a new “aeon” in the history of the universe.”
The core concept in Penrose’s theory is the idea that in the very distant future the universe will in one sense become very similar to how it was at the Big Bang. Penrose says that “at these points the shape, or geometry, of the universe was and will be very smooth, in contrast to its current very jagged form. This continuity of shape, he maintains, will allow a transition from the end of the current aeon, when the universe will have expanded to become infinitely large, to the start of the next, when it once again becomes infinitesimally small and explodes outwards from the next big bang.
Crucially, he says, the entropy at this transition stage will be extremely low, because black holes, which destroy all information that they suck in, evaporate as the universe expands and in so doing remove entropy from the universe.”
The foundation for Penrose’s theory is found in the cosmic microwave background, the all-pervasive microwave radiation that was believed to have been created when the universe was just 300,000 years old and which tells us what conditions were like at that time. The evidence was obtained by Vahe Gurzadyan of the Yerevan Physics Institute in Armenia, who analysed seven years’ worth of microwave data from WMAP, as well as data from the BOOMERanG balloon experiment in Antarctica.
Penrose and Gurzadyan say they have clearly identified concentric circles within the data – regions in the microwave sky in which the range of the radiation’s temperature is markedly smaller than elsewhere. The Cosmic Microwave Background (CMB) radiation is the remnant heat from the Big Bang. This radiation pervades the universe and, if we could see in microwaves, it would appear as a nearly uniform glow across the entire sky.
However, when we measure this radiation very carefully we can discern extremely faint variations in the brightness from point to point across the sky, called “anisotropy”. These variations encode a great deal of information about the properties of our universe, such as its age and content. The “Wilkinson Microwave Anisotropy Probe” (WMAP) mission has measured these variations and found that the universe is 13.7 billion years old, and it consists of 4.6% atoms, 23% dark matter, and 72% dark energy.
According to Penrose and Gurzadyan, as described in arXiv: 1011.3706, these circles allow us to “see through” the Big Bang into the aeon that would have existed beforehand. They are the visible signature left in our aeon by the spherical ripples of gravitational waves that were generated when black holes collided in the previous aeon.
The “Penrose circles” pose a huge challenge to inflationary theory because this theory says that the distribution of temperature variations across the sky should be Gaussian, or random, rather than having discernable structures within it.
Julian Barbour, a visiting professor of physics at the University of Oxford in an interview with Physics World, says that these circles would be “remarkable if real and sensational if they confirm Penrose’s theory”. They would “overthrow the standard inflationary picture”, which, he adds, has become widely accepted as scientific fact by many cosmologists. But he believes that the result will be “very controversial” and that other researchers will look at the data very critically. He says there are many disputable aspects to the theory, including the abrupt shift of scale between aeons and the assumption, central to the theory, that all particles will become massless in the very distant future.
He points out, for example, that there is no evidence that electrons decay. Penrose and colleague Gurzadyn have answered the numerous critics who say that the circles do not contradict the standard model of cosmology in follow up paper, published on arXiv. In the short article, they agree that the presence of circles in the CMB does not contradict the standard model of cosmology.
However, the existence of “concentric families” of circles, they argue, cannot be explained as a purely random effect given the pure Gaussian nature of their original analysis. “It is, however a clear prediction of conformal cyclic cosmology,” reports Physics World.
The iBrain is part of a new generation of portable neural devices and algorithms intended to monitor and diagnose conditions like sleep apnea, depression and autism. Invented by a team led by Philip Low, a 32-year-old neuroscientist who is chief executive ofNeuroVigil, a company based in San Diego, the iBrain is gaining attention as a possible alternative to expensive sleep labs that use rubber and plastic caps riddled with dozens of electrodes and usually require a patient to stay overnight.
“The iBrain can collect data in real time in a person’s own bed, or when they’re watching TV, or doing just about anything,” Dr. Low said.
The device uses a single channel to pick up waves of electrical brain signals, which change with different activities and thoughts, or with the pathologies that accompany brain disorders.
About the Hawking experiment, he said, “The idea is to see if Stephen can use his mind to create a consistent and repeatable pattern that a computer can translate into, say, a word or letter or a command for a computer.”
The researchers traveled to Dr. Hawking’s offices in Cambridge, England, fitted him with the iBrain headband and asked him “to imagine that he was scrunching his right hand into a ball,” Dr. Low said. “Of course, he can’t actually move his hand, but the motor cortex in his brain can still issue the command and generate electrical waves in his brain.”
The algorithm, called Spears, was able to discern Dr. Hawking’s thoughts as signals, which were represented as a series of spikes on a grid.
Stephen Hawking has advised,he never states anything,not to contact Aliens and avoid talking to them.
Even if you follow this sagely wisdom,at best you may not reply when they contact you.
You can not avoid being located / contacted by them, if they are Advanced Species.
The Theory that all Aliens are set to conquer Alien Planets seems to be influenced by Hollywood pulp and Movies.
There is no supporting evidence for Hawking’s statement.
A scientist should stick to facts , at least some semblance of reasoning.
Mankind has always been apprehensive about New Discoveries always fearing the worst.
As of date no catastrophe excepting what we have made like dropping of Atomic Bombs, has been noticed.

British theoretical physicistStephen Hawking has warned of the dangers of attempting to contact extra-terrestrial life. One of the world’s leading scientists, he says that aliens almost certainly exist but mankind should be doing everything they can to avoid contact.
“To my mathematical brain, the numbers alone make thinking about aliens perfectly rational,” he said. “The real challenge is to work out what aliens might actually be like.”
His views are expressed in a new documentary made for the Discovery Channel. In it he points out that the universe has more than 100 billion galaxies, each containing hundreds of millions of stars. In such circumstances, Earth is unlikely to be the only planet where life has evolved, Hawking claims.
While many forms of life may be little more than microbes, Hawking says a few life forms could be intelligent and pose a threat to the human race. Aliens might simply raid Earth for its resources and then move on.
“We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet. I imagine they might exist in massive ships, having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonise whatever planets they can reach,” Hawking says.
