This new theory which says Earth’s gravity captures these tiny asteroids as they pass near the planet on their way around the sun.
When one of them is drawn in, it typically makes three irregularly shaped swings such as huge doughnuts around Earth for a while and then hurtles on its way.
Scientists claim that little attention has been paid to Earth’s natural satellites other than the moon, despite the fact that they are sure to exist.
“There are lots of asteroids in the solar system, so chances for the Earth to capture one at any time is, in a sense, not surprising,” said co-author and astronomer at the Paris Observatory in France Jeremie Vauballion.
The group says the temporary asteroids have orbited Earth for about a year starting in June 2006 when an object, labeled 2006 RH120, was discovered by the Catalina Sky Survey in Arizona and estimated to be between 3 and 6 meters wide.
“The 2006 RH120 was probably discovered because it was slightly larger than most of the other ‘temporary moons’ that later have come into our planetary system as most of them are only about 1 meter wide,” scientists say.
There are thousands of military facilities around the world that defy conventional attack. Caves in Afghanistan burrow into mountainsides, and immense concrete bunkers lie buried deep in the sand in Iraq. These hardened facilities house command centers, ammunition depots and research labs that are either of strategic importance or vital to waging war. Because they are underground, they are hard to find and extremely difficult to strike. Read the rest of this entry
Hunting Aliens continues its course, Enthusiasm about finding their worlds nestled inside other stars’ habitable zones is so strong that in 2008 a radio message was beamed to a planet known to exist in the habitable zone of the red dwarf star Gliese 581, located 20 light-years away. The signal contains 501 greetings that were selected through a competition on a social networking site. Read the rest of this entry
All of the foregoing today devices are mostly manufactured with an “embedded” wireless networking chip that became common for manufacturers to allow anywhere and permanent internet data access. All new laptops, tablets, Smartphone, PDA are now manufactured with an integration of 3-way wireless capability: Wi-Fi, Bluetooth, and GSM/GPRS/3G/4G/LTE/LT-A…this make all devices around us truly computer devices capacity in the direction that Computer is disappearing on its early centralized form.
Millions of people are now using Social Media and Network to even stay in touch with families, relatives and colleague from everywhere they are, including coffee shops, hotels, airports, college campuses, and libraries.
3G, LTE and LTE-A networks have evolved to incorporate high-speed internet access and video telephony that today the proliferation of Mobile Apps change the Business model of Mobile Operator who are offering open and flat rate package to user who are now moving into flexible use with a predefine data connection fee..
Corporate marketers start thinking how they can leverage more their presence on Social networks and media. Some of these social sites are flexible enough to offer to consumers who are spending lot of their personal and office time looking for consumer base data.
For this trend we are seeing with Social sites based on the Web 2.0 framework, Seleani is projecting the enhancement of the automation and dynamic data that today social computing is delivering to end users. We precisely think the need of making the user Profile more virtual reality by allowing affiliation between contact on family tree group to announce sickness and death event realities. Not only updating the data but also to trigger all those who are in contact to see a new announcement for sickness or death news. We also extend this flow to the direction of updating and add new group on profiles where death, cemetery or graveyards will be updated automatically whenever a contact members has lost his life. We additionally propose the need of affiliating a son or the nearest relative to disable the Active stat into Death stats of the blessed lost father or relatives.
The ROI of such change on today social computing is clear to make advertisers and manufacturers more sharp to target consumers but also a wide range of life saving possibility than the actual pure virtual life we are spending. We will realize an enhancement of our real life that changing it into a virtual world that cannot be the objective need of Technology Innovations.
Facebook did not care as those who do not use it
And never deletes anything, the network would be in total violation of European law.
We suspected, Facebook does not erase anything. What we did not know, however, is that the social network would also records on people who are not registered to the service. Read the rest of this entry
Same as we have said earlier, time travel subject is more practical than theoretical reality that the community of science fiction speculates over years than in R&D of science. Recently there is speculation among premature CERN researchers, saying that that there could be sub-neutrino particles that have a speed faster than light in vacuum. Fortunately, even if such research is verified, there is always a question of the maximum propulsive energy for the spacecraft to carry out missions in space-time travel.. Read the rest of this entry
GENEVA: A startling find at one of the world’s foremost laboratories that a subatomic particle seemed to move faster than the speed of light has scientists around the world rethinking Albert Einstein and one of the foundations of physics. Now they are planning to put the finding — and by extension Einstein –to further high-speed tests to see if a revolutionary shift in explaining the workings of the universe is needed — or if the European scientists made a mistake.
Researchers at CERN, the European Organization for Nuclear Research, who announced the discovery Thursday are still somewhat surprised themselves and planned to detail their findings on Friday.
If these results are confirmed, they won’t change at all the way we live or the way the universe behaves. After all, these particles have presumably been speed demons for billions of years. But the finding will fundamentally change our understanding of how the world works, physicists said.
Only two labs elsewhere in the world can try to replicate the results. One is Fermilab outside Chicago and the other is a Japanese lab put on hold by the tsunami and earthquake. Fermilab officials met Thursday about verifying the European study and said their particle beam is already up and running. The only trouble is that the measuring systems aren’t nearly as precise as the Europeans’ and won’t be upgraded for a while, said Fermilab scientist Rob Plunkett.
“This thing is so important many of the normal scientific rivalries fall by the wayside,” said Plunkett, a spokesman for the Fermilab team’s experiments. “Everybody is going to be looking at every piece of information.”
Plunkett said he is keeping an open mind on whether Einstein’s theories need an update, but he added: “It’s dangerous to lay odds against Einstein. Einstein has been tested repeatedly over and over again.”
Going faster than light is something that is just not supposed to happen according to Einstein’s 1905 special theory of relativity _ the one made famous by the equation E equals mc2. Light’s 186,282 miles per second (299,792 kilometers per second) has long been considered the cosmic speed limit. And breaking it is a big deal, not something you shrug off like a traffic ticket.
“We’d be thrilled if it’s right because we love something that shakes the foundation of what we believe,” said famed Columbia University physicist Brian Greene. “That’s what we live for.”
The claim is being greeted with skepticism inside and outside the European lab.
“The feeling that most people have is this can’t be right, this can’t be real,” said James Gillies, a spokesman for CERN, which provided the particle accelerator to send neutrinos on their breakneck 454-mile trip underground from Geneva to Italy. France’s National Institute for Nuclear and Particle Physics Research collaborated with Italy’s Ran Sass National Laboratory for the experiment, which has no connection to the Large Harden Collider located at CERN.
Gillies told The Associated Press that the readings have so astounded researchers that “they are inviting the broader physics community to look at what they’ve done and really scrutinize it in great detail.”
That will be necessary, because Einstein’s special relativity theory underlies “pretty much everything in modern physics,” said John Ellis, a theoretical physicist at CERN who was not involved in the experiment. “It has worked perfectly up until now.” And part of that theory is that nothing is faster than the speed of light.
CERN reported that a neutrino beam fired from a particle accelerator near Geneva to a lab 454 miles (730 kilometers) away in Italy traveled 60 nanoseconds faster than the speed of light. Scientists calculated the margin of error at just 10 nanoseconds, making the difference statistically significant.
Given the enormous implications of the find, they spent months checking and rechecking their results to make sure there were no flaws in the experiment.
A team at Fermilab had similar faster-than-light results in 2007. But that experiment had such a large margin of error that it undercut its scientific significance.
If anything is going to throw a cosmic twist into Einstein’s theories, it’s not surprising that it’s the strange particles known as neutrinos. These are odd slivers of an atom that have confounded physicists for about 80 years.
The neutrino has almost no mass, it comes in three different “flavors,” may have its own antiparticle and even has been seen shifting from one flavor to another while shooting out from the sun, said physicist Phillip Schewe, communications director at the Joint Quantum Institute in Maryland.
Fermilab team spokeswoman Jenny Thomas, a physics professor at the University College of London, said there must be a “more mundane explanation” for the European findings. She said Fermilab’s experience showed how hard it is to measure accurately the distance, time and angles required for such a claim.
Nevertheless, the Fermilab team, which shoots neutrinos from Chicago to Minnesota, will go back to work immediately to try to verify or knock down the new findings, Thomas said.
Drew Baden, chairman of the physics department at the University of Maryland, said it is far more likely that there are measurement errors or some kind of fluke. Tracking neutrinos is very difficult, he said.
“This is ridiculous what they’re putting out,” Baden said, calling it the equivalent of claiming that a flying carpet is invented only to find out later that there was an error in the experiment somewhere. “Until this is verified by another group, it’s flying carpets. It’s cool, but…”
So if the neutrinos are pulling this fast one on Einstein, how can it happen?
Stephen Parke, who is head theoretician at the Fermilab said there could be a cosmic shortcut through another dimension — physics theory is full of unseen dimensions — that allows the neutrinos to beat the speed of light.
Indiana University theoretical physicist Alan Kostelecky, theorizes that there are situations when the background is different in the universe, not perfectly symmetrical as Einstein says. Those changes in background may change both the speed of light and the speed of neutrinos.
But that doesn’t mean Einstein’s theory is ready for the trash heap, he said.
“I don’t think you’re going to ever kill Einstein’s theory. You can’t. It works,” Kostelecky said. Just there are times when an additional explanation is needed, he said.
If the European findings are correct, “this would change the idea of how the universe is put together,” Columbia’s Greene said. But he added: “I would bet just about everything I hold dear that this won’t hold up to scrutiny.”
Probably one of the highest risk/reward activity in modern science is being conducted by a very small group of astronomers: the search for signals from extraterrestrial civilizations (SETI). Read the rest of this entry
Time travel is part of the predicted consequences by Einstein Special and general relativities. Special relativity (SR, also known as the special theory of relativity or STR) is the physical theory of measurement in inertial frames of reference proposed in 1905 by Einstein after the considerable and independent contributions of Hendrik Lorentz, Henri Poincare (and others) in the paper “On the Electrodynamics of Moving Bodies”.
It generalizes Galileo’s principle of relativity that all uniform motion is relative and that there is no absolute and well-defined state of rest (no privileged reference frames) from mechanics to all the laws of physics, including both the laws of mechanics and of electrodynamics, whatever they may be. Special relativity incorporates the principle that the speed of light is the same for all inertial observers regardless of the state of motion of the source.
This theory has a wide range of consequences among them twice on space-time and that some which have been experimentally verified, including counter-intuitive ones such as length contraction, time dilation and relativity of simultaneity, contradicting the classical notion that the duration of the time interval between two events is equal for all observers. (On the other hand, it introduces the space-time interval, which is invariant.) Combined with other laws of physics, the two postulates of special relativity predict the equivalence of matter and energy, as expressed in the mass–energy equivalence formula E = mc2, where c is the speed of light in a vacuum. The predictions of special relativity agree well with Newtonian mechanics in their common realm of applicability, specifically in experiments in which all velocities are small compared with the speed of light. Special relativity reveals that c is not just the velocity of a certain phenomenon namely the propagation of electromagnetic radiation (light) but rather a fundamental feature of the way space and time are unified as space-time. One of the consequences of the theory is that it is impossible for any particle that has rest mass to be accelerated more or equal to the speed of light.
The theory was originally termed “special” because it applied the principle of relativity only to the special case of inertial reference frames, i.e. frames of reference in uniform relative motion with respect to each other. Einstein developed general relativity to apply the principle in the more general case, that is, to any frame so as to handle general coordinate transformations, and that theory includes the effects of gravity.
The term is currently used more generally to refer to any case in which gravitation is not significant. General relativity is then the generalization of special relativity to include gravitation that you can have some details on our Seleani Youtube videos. In general relativity, gravity is described to be represented by curvature of space-time while special relativity was restricted to flat space-time. Just as the curvature of the earth’s surface is not noticeable in everyday life, the curvature of space-time can be neglected on small scales, so that locally, special relativity is a valid approximation to general relativity. The presence of gravity becomes undetectable in a sufficiently small, free-falling laboratory.
General relativity was published by Albert Einstein in 1916. It is the current description of gravitation in modern physics. General relativity generalizes special relativity and Newton’s law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or space-time.
Some predictions of general relativity differ significantly from those of classical physics, especially concerning the passage of time, the geometry of space, the motion of bodies in free fall, and the propagation of light. Examples of such differences include gravitational time dilation (which is the basic mean of Future time travel possibility against the impossibility of travelling to the past), gravitational lensing, the gravitational redshift of light, and the gravitational time delay (which shows that 2 different space-time places evolve differently through time). General relativity’s predictions have been confirmed in all observations and experiments to date. Although general relativity is not the only relativistic theory of gravity, it is the simplest theory that is consistent with experimental data. However, unanswered questions remain, the most fundamental being how general relativity can be reconciled with the laws of quantum physics to produce a complete and self-consistent theory of quantum gravity that we help us to make time travel possible where quantum and lightening physics can play a very big role in cosmology for more space and Universe exploration. This will be our next videos to talk how these conceptual topics are very interesting in today technology and Business life…
Einstein’s theory has important astrophysical implications. For example, it implies the existence of black holes, regions of space in which space and time are distorted in such a way that nothing, not even light, can escape as an end-state for massive stars. There is ample evidence that such stellar black holes as well as more massive varieties of black hole are responsible for the intense radiation emitted by certain types of astronomical objects such as active galactic nuclei or micro quasars. The bending of light by gravity can lead to the phenomenon of gravitational lensing, where multiple images of the same distant astronomical object are visible in the sky. General relativity also predicts the existence of gravitational waves, which have since been measured indirectly; a direct measurement is the aim of projects such as LIGO and NASA/ESA Laser Interferometer Space Antenna. In addition, general relativity is the basis of current cosmological models of a consistently expanding universe that Stephen hawking is leading on deep universe exploration and took the black hole as his main tasks to achieve before passing away of his present life…
So in short, time travel could be possible only for the Future reference to the law of physics, with a concept called wormhole which is a hypothetical topological feature of space-time that would be, fundamentally, a “shortcut” through space-time. For a simple visual explanation of a wormhole, consider space-time visualized as a two-dimensional (2D) surface. If this surface is folded along a third dimension, it allows one to picture a wormhole “bridge” from a spacetime A to another space-time B; much like a tunnel with two ends each in separate points in spacetime, or it can be also known as two connecting black holes.
To cross a wormholes; it could actually be possible if exotic matter with negative energy density could be used to stabilize them. (Many physicists such as Stephen Hawking, Kip Thorne, and others believe that the Casimir effect is evidence that negative energy densities are possible in nature). Physicists have also not found any natural process which would be predicted to form a wormhole naturally in the context of general relativity, although the quantum foam hypothesis is sometimes used to suggest that tiny wormholes might appear and disappear spontaneously at the Planck scale (10 exp-43 s), and stable versions of such wormholes have been suggested as dark matter candidates. It has also been proposed that if a tiny wormhole held open by a negative-mass cosmic string had appeared around the time of the Big Bang, it could have been inflated to macroscopic size by cosmic inflation……To be continued in www.seleani.com
Inventors… innovators… entrepreneurs… these terms are often used interchangeably by many people. Several corporate who are mostly in Technology are always putting on their profiles, innovative company, innovative services, and innovative products. Yet I would argue that they all refer to different links in the total common value-chain of progress they do.
While inventors are more idea-oriented and entrepreneurs are more action-oriented, they both share an approach to problem solving that is non-linear. Innovators, however, can either be linear or non-linear. The linear innovators tend to be evolutionary, making incremental improvements, while the non-linear innovators tend to be revolutionary (not simply the Arab uprisingJ).
We can all think of innovations that were revolutionary in nature; the automobile, the phonograph, the Internet. Likewise, we can also think of more linear innovations that were evolutionary: better engines for cars; better sound systems for the phonograph; the World Wide Web (enabled by another incremental invention, html code, scripting etc..) for the Internet and communication.
Evolutionary innovators ask questions based on the limitations of existing solutions while revolutionary innovators ask questions no one else has thought of before. This sentiment was eloquently captured by Robert Kennedy when he paraphrased a quote by George Bernard Shaw: “Some people see things as they are and say why? I dream things that never were and say why not.”
While both types of innovation play a vital role in the developmental ecosystem of technology, industry and business, it is the non-linear or revolutionary innovations that make the most significant advances. These are the ones that make the real difference. The really huge achievements in technology and the world at large are the result of visionary activists who imagine and then build something none of us had previously thought possible.
In the era of Karl Benz, the light bulb, the phonograph, the telephone, and the automobile embodied this vision for possibilities that did not yet exist. But while quantum leaps like this tend to get more attention than incremental improvements, we should not minimize the importance of evolutionary innovations, the accumulation of which make the world a better living place through millions of small, gradual steps. Many incremental improvements become far better products and businesses.
For the most part, revolutionary ideas are implemented and commercialized by entrepreneurs who make evolutionary advances: the Wright brothers may have invented the airplane, but it was innovations such as airmail, military air forces, and commercial airlines that evolved the invention into a commercial enterprise.
The precursor to today’s steam engine the Greek Aeolipile invented in the 1st century by Heron of Alexendria went nowhere because no evolutionary innovator picked up on it to take it to the next level. Even after the first automobile was developed by Benz, mass adoption took decades. The car would not have revolutionized so many lives if someone hadn’t figured out how to mass-produce cars at an affordable price.
Here now the activity Quiz to answer and comment…
Please arrange below list on 2 groups of Revolutionary Innovations vs Evolutionary Innovations
internal combustion engine,
World Wide Web
Reasonable people can debate whether a particular innovation belongs in the first category or the second. What is not debatable is that while both play a role in the ecology of innovation, it is the truly revolutionary innovations that make all subsequent incremental improvements possible in our life that Seleaninews brings daily innovation to whether existing ideas or new ones.
