Nasa to launch faulty space shuttle

2009-03-17T19:36:00.001+05:30

Nasa to launch faulty space shuttle Monday, March 16, 2009WASHINGTON: The US space agency will break with protocol and try to launch the space shuttle Discovery late on Sunday even though it has yet to uncover the cause of a hydrogen leak that delayed its mission earlier in the week, officials said. On Saturday, Nasa scheduled Discovery and its crew of seven, including a Japanese

DISC: How would one warp space-time to create a funnel that can be traveled through?

2008-07-15T14:16:00.001+05:30

Say I want to crete a sort of spiral of space-time or a time funnel/spiral [whatever you want to call it]. Or just warp space so it's bigger in front of you and smaller behind you .This would cause near instantaneous travel over many light years. But it would be difficult getting it to stabalize and have all your atoms put in the right place.

What happens when space and time reverse on the interior of a black hole?

2008-07-15T14:04:00.001+05:30

According to the Schwarzschild metric, when you travel through the event horizon of a black hole, the (previous) radial-like coordinate becomes positive and the (previous) time-like coordinate becomes negative. This suggests that the old radius is now a time-like coordinate (which must always move towards the singularity) and the old time is now a space-like coordinate that can be traveled in

Earth Cries to outer space

2008-07-02T16:02:00.001+05:30

Scientists have been able to record the ear-piercing series of chirps and whistles which the earth emits and which could be heard by any aliens who might be listening. The sound is awful, the recording from space reveals. Researchers have known about the radiation since the 1970s. It is created high above the planet, where charged particles from the solar wind collide with Earth's magnetic field

WormHoles

2008-07-01T20:36:00.001+05:30

In physics, a wormhole is a hypothetical topological feature of spacetime that is essentially a "shortcut" through space and time. A wormhole has at least two mouths which are connected to a single throat. If the wormhole is traversible, matter can 'travel' from one mouth to the other by passing through the throat. The name "wormhole" comes from the following analogy used to explain the

Jumping for (Scientific) Joy

"Watson, come here! I need you!" March 10, 1876: When Alexander Graham Bell called for help after spilling acid on himself, he was shouting through a "voice telegraph" device and, inadvertently, placing the world's very first telephone call. From that point forward, we've been able to cast our voices almost anywhere on the planet, with the expectation of an instantaneous reply. Distance collapses

Jumper's Tricked-Out Teleportation: Hollywood Sci-Fi vs. Reality Teleportation has long been the object of real-world desire—not to mention sci-fi speculation, from Star Trek to The Twilight Zone to Heroes.

what we might mean by the term "teleportation." After all, if someone comes up to you saying "look I've finally done it! I've discovered how to teleport ..." we'd like to be able to decide whether we were even speaking the same language. Fine, so I've seen Star Trek ® so I figure I can take a stab at defining it: Teleportation is some kind of instantaneous "disembodied" transport. Now wait a

How Teleportation Will Work

2008-07-01T20:14:00.001+05:30

Ever since the wheel was invented more than 5,000 years ago, people have been inventing new ways to travel faster from one point to another. The chariot, bicycle, automobile, airplane and rocket have all been invented to decrease the amount of time we spend getting to our desired destinations. Yet each of these forms of transportation share the same flaw: They require us to cross a physical

It is bluff from some blog but interesting hence, reproducing it .. Russian scientists have claimed that time travel could take place this year as an inadvertent by-product of the Large Hadron Collider (LHC) run by Cern. Mathematicians Irina Aref'eva and Igor Volovich said that when the LHC begins to smash atoms into each other the conditions will be perfect to open a wormhole into the distant

Quantum Teleportation

2008-07-01T20:11:00.001+05:30

Teleportation is the name given by science fiction writers to the feat of making an object or person disintegrate in one place while a perfect replica appears somewhere else. How this is accomplished is usually not explained in detail, but the general idea seems to be that the original object is scanned in such a way as to extract all the information from it, then this information is transmitted

Teleportation

2008-07-01T20:10:00.001+05:30

Teleportation is the movement of objects from one place to another, more or less instantaneously, either by paranormal means or through technological artifice. The concept has been widely used in science fiction. Similar is apport, an earlier word used to describe what today might be called teleportation; and bilocation, when something or someone described as being a magician is said to be able

What do I think?

2008-07-01T20:06:00.004+05:30

Regardless of the theories, I cannot believe that time travel will ever be possible. My main reason for this is because we have recorded history and we know what events happened in the past, and in our own recent past we even have our own memories of past experiences. If time travel were possible then we could not have a recorded history because it would be constantly changing. I can remember,

Constructing a time machine

2008-07-01T20:06:00.003+05:30

Research carried out in the late 1980's showed that genuine time travel is not forbidden by the known laws of physics. This means that it may be possible to build a time machine, but not that it may be easy. Help may be at hand though, it is possible there are naturally occurring objects in the universe that act as time machines. There are at least two ways to build a time machine. Frank Tipler

Alternate Universes

2008-07-01T20:06:00.001+05:30

The idea of having alternate Universes very conveniently solves the paradoxes raised by time travel, but is it a serious possibility? It sounds a bit far fetched, like something out of a science fiction paperback, but try not to dismiss the idea out of hand, it has some strong supporters. The alternative universe theory (also known as the multiverse) suggests that for every possible outcome of

Paradoxes of Time Travel

2008-07-01T20:05:00.003+05:30

This is where we start to run into some of the problems posed by time travel. The most commonly posed paradox is known as the 'grand parent' paradox. This states that if you could travel back in time you could murder your grand parents and thus prevent your existence, thus rendering it impossible for you to have gone back in time and killed them... no need to draw you a picture. Even more to the

Is time travel possible?

2008-07-01T20:05:00.001+05:30

Time travel is a concept much loved by science fiction writers, and Star Trek fans, but is it possible within the known laws of physics? To answer the question we shall take another look at quantum theory, (see What is Quantum Mechanics?) bringing in the ideas of Richard Feynman, and re-examine the theory of relativity. After that we shall consider the difficulties involved in constructing a time

The Physics of Black Hole X-ray Transients

2008-07-01T20:03:00.001+05:30

The most plausible mechanism for triggering the outburst of black hole candidate X-ray transients is the ionization thermal instability. The disk instability models can give the observed mass flow in quiescence, but not the X-ray spectrum. Self-irradiation of the disk in outburst may not lead to X-ray reprocessing as the dominant source of optical light, but may play a role in the "reflare." The

Parallel universe proof boosts time travel hopes

The phase space time evolution model of Huizenga and Storchi and Morawska-aczynska and Huizenga has been modified to accommodate calculations of energy deposition by arbitrary electron beams in three-dimensional heterogeneous media. This is a further development aimed at the use of the phase space evolution model in radiotherapy treatment planning. The model presented uses an improved method to

The mathematical relationship between the Phase Space Time Evolution method and the neutron transport equation

2008-06-28T12:47:00.001+05:30

The neutron transport equation is shown to be analytically related to a quasi-simulation method called the Phase Space Time Evolution (PSTE) Technique. The analysis establishes the mathematical connection between two apparently different methods of treating particle/wave transport. With this relationship known, it is now possible to use quasi-simulation methods for nonphysical particles such as

What is Gravity Probe B?

2008-03-15T14:14:00.003+05:30

Physicists and engineers at Stanford University have created a wide range of exotic technologies to perform a satellite experiment that will probe the very foundations of space time. Gravity Probe B is the relativity gyroscope experiment being developed by NASA and Stanford University to test two extraordinary, unverified predictions of Albert Einstein's general theory of relativity. The

Einstein after Seven Decades

2008-03-15T14:14:00.001+05:30

Einstein forever altered our thinking about space, time and the Universe, but some of his most basic ideas remain untested and bafflingly at odds with the rest of modern physics. Why after almost eighty years do we still need to test Einstein's theory of general relativity? The answer is that although it is among the most brilliant creations of the human mind, weaving together space, time,

The Surprising Spin-Offs from Gravity Probe B: Schiff's Cargo

2008-03-15T14:12:00.001+05:30

The many new technologies of Gravity Probe B have spin-offs to astronomy, oceanography, navigation, metrology, and fundamental physics. And a human spin-off- the education of aspiring physicists and engineers. Who could have guessed in 1959, when Leonard Schiff submitted to the American Journal of Physics a short teaching article about the inadequacies of experimental relativity, that thirty

Four Hundred Miles Above the Ivory Tower: A Coherent Flight Program

2008-03-15T14:11:00.001+05:30

In 1984, the NASA administrator described Gravity Probe B as not only an exciting relativity mission but also a "very interesting management experiment." Gravity Probe B launched in the spring of 2004, more than forty years after Schiff's work. That it signifies more theoretically now than in 1960 proves Schiff's acumen. The concept is simple: a spinning sphere, a telescope, a star, each

Joining Quartz and Splitting a Star: The Telescope and the Quartz Block

The 200-year-old art of optical contacting, combined with new design principles and modern photodetectors, yields a telescope of unprecedented stability and precision. The gyro spin directions are referred via a quartz block to the telescope, and the telescope to the guide star. Truthful data demands a stable mechanical structure and a telescope capable, like the gyroscopes, of measuring angular

Jewel-like spheres of fused quartz , the size of ping-pong balls, each coated with a very thin, very uniform, chemically pure, mechanically robust, electrically stable layer of the metal niobium, the gyro rotors are

The Shaping of Gravity Probe B: A Unified Experiment

2008-03-15T14:09:00.001+05:30

Much more than a precise gyroscope is needed in Gravity Probe B: the experiment has to be conceived as an architectonic whole, with physics and engineering principles skillfully united. The gyroscopes for Gravity Probe B have to provide a reference system stable to 10-11 degrees/hour -- a million times better than the best inertial navigation gyroscopes. Better, really. In inertial navigation

The Geodetic Effect: Measuring the Curvature of Space-time

2008-03-15T14:07:00.001+05:30

According to Einstein the Earth warps space-time. A second, much larger change in spin direction, the geodetic effect, follows from the gyroscope's motion through this space-time curvature. The phenomenon was foreshadowed in 1916 by W. de Sitter who predicted a minute relativistic correction to the complicated motions of the Earth-Moon system around the Sun -- an effect finally detected in 1988

Frame-dragging: Measuring the Rotation of Space-time

2008-03-15T14:06:00.001+05:30

In 1918, two years after Einstein formulated general relativity, W. Lense and H. Thirring calculated that according to the theory a rotating massive body should slowly drag space and time around with it! Startling and far-reaching as Lense & Thirring's discovery was, any verification of frame-dragging seemed hopeless. Nothing happened until 1959 when physicist George Pugh, an MIT professor

Directionality in Space-Time

2008-03-15T14:04:00.001+05:30

What is a gyroscope ? The first, invented in 1852 by the French physicist J. B. L. Foucault, was an instrument for studying the Earth's rotation by means of a freely suspended flywheel. Since then gyroscopes have found many applications, especially in navigation, and many types exist. The ones for Gravity Probe B are not flywheels but electrically supported spheres, spinning in a vacuum. Others

TIME IS OF THE ESSENCE IN SPECIAL RELATIVITY

2008-03-15T13:50:00.001+05:30

When it comes to Einstein's theory of special relativity, everyone thinks about the famous equation E = mc2, but the truly revolutionary aspect of the theory is the treatment of time. Prior to Einstein, time was regarded as a universal measure for all observers, no matter whether they were at rest, or traveling with high speed relative to each other. This point of view led to serious

Light bending If we imagine observing a beam of light in an accelerated elevator we will see that the light path is curved. By the equivalence principle the same must be true for light whenever gravitational forces are present. This was tested by carefully recording the position of stars near the rim of the sun during an eclipse (see Fig. 7.22) and then observing the same stars half a year

The conclusions to be drawn from all these arguments are, All frames of reference are equivalent, provided we are willing to include possible gravitational effects (in non-inertial or accelerated frames forces will appear which are indistinguishable from gravitational forces). Space-time is a dynamic object: matter curves it, and the way in which it is curved determines the motion of matter

A classical way of picturing the manner in which heavy bodies curve space is to imagine a rubber sheet. When a small metal ball is made to roll on it it will go in a straight line at constant speed (neglecting friction). Now imagine that a heavy metal ball is placed in the middle of the sheet; because of its weight the sheet will be depressed in the middle (Fig 7.13). When a small ball is set

When considering the beings living on a sphere it is easy for us to differentiate between the sphere and some plane surface: we actually see the sphere being curved. But when it comes to us, and our curved space, we cannot see it since this would entail our standing outside space and looking down on it. Can we then determine whether space is curved by doing measurements inside it? To see that

Space and time. When considering the Special Theory of Relativity we concluded that the state of motion of an observer with respect to, say, a laboratory, determines the rate at which his/her clocks tick with respect to the lab's clocks (see Sect. 6.2.3). Thus, in this sense, time and space mingle: the position of the observer (with respect to the lab's measuring devices) determines, as time

Problems with Time Travel

2006-11-30T13:44:00.001+05:30

If we are ever able to develop a workable theory for time travel, we would open up the ability to create very complicated problems called paradoxes. A paradox is defined as something that contradicts itself. Here are two common examples:Let's say, for the sake of argument, that you could travel back to a time before you were born. The mere fact that you could exist in a time before you were born

Time travel in theory

2006-11-30T13:42:00.000+05:30

Some theories, most notably special and general relativity, suggest that suitable geometries of spacetime, or specific types of motion in space, may allow time travel into the past and future if these geometries or motions are possible.Concepts that aid such understanding include the closed timelike curve.Although the possibility of traveling to the future by moving at relativistic velocities is

2006-11-30T13:39:00.000+05:30

THE laws of physics seem to permit time travel, and with it, paradoxical situations such as the possibility that people could go back in time to prevent their own birth. But it turns out that such paradoxes may be ruled out by the weirdness inherent in laws of quantum physics.Some solutions to the equations of Einstein's general theory of relativity lead to situations in which space-time curves

What is Time Travel

2006-11-30T13:38:00.000+05:30

Time travel is the concept of moving backward or forward to different points in time, in a manner analogous to moving through space. Additionally, some interpretations of time travel suggest the possibility of travel between parallel realities or universes.

OUR PICTURE OF THE UNIVERSE - By Stephen Hawkings

2006-11-30T13:19:00.000+05:30

A well-known scientist (some say it was Bertrand Russell) once gave a public lecture on astronomy. Hedescribed how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vastcollection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: “What you have told us is rubbish. The world is really a flat plate

Before God we are all equally wise - and equally foolish.Do not worry about your difficulties in Mathematics. I can assure you mine are still greater.Ethical axioms are found and tested not very differently from the axioms of science. Truth is what stands the test of experience.Every day I remind myself that my inner and outer life are based on the labors of other men, living and dead, and that I

THE RELATIVISTIC UNIVERSE

2006-11-10T16:19:00.000+05:30

In Einstein's universe, mass is converted into energy in the cores of stars, enabling them to shine, while matter curves space, and time flows faster or slower depending on relative motion or gravity. Einstein's General Theory of Relativity has largely stood the test of time; its manifestations are much evident in the observable universe. Indeed, current models of how the cosmos began and

How We Detect Black Holes

How We Detect Black HolesAlthough we cannot see black holes, we can detect or guess the presence of one by measuring its effects on objects around it. The following effects may be used: Mass estimates from objects orbiting a black hole or spiraling into the core Gravitational lens effects Emitted radiation MassMany black holes have objects around them, and by looking at the behavior of the

What is a Black Hole?

2006-11-02T19:35:00.000+05:30

What is a Black Hole?A black hole is what remains when a massive star dies. If you have read How Stars Work, then you know that a star is a huge, amazing fusion reactor. Because stars are so massive and made out of gas, there is an intense gravitational field that is always trying to collapse the star. The fusion reactions happening in the core are like a giant fusion bomb that is trying to

How Time Travel Will Work

2006-11-02T19:26:00.000+05:30

There may be no other concept that captures the imagination more than the idea of time travel -- the ability to travel to any point in the past or future. What could be cooler? You could jump into your time machine to go back and see major events in history and talk to the people who were there! Who would you travel back to see? Julius Caesar? Leonardo da Vinci? Elvis? You could go back and meet

Small travel

2006-11-02T19:20:00.000+05:30

Small travelToday, the only way to "travel" to the future cannot be used to travel over long periods of time -- only less than a single second. It is so insignificant that it is usually not mentioned at all. And the only people that have used this method have been astronauts. Basically, the longer a person is in orbit around the Earth, the younger the astronaut will be in relation to observers on

Atoms of Space and Time

Atoms of Space and TimeA little more than 100 years ago most people - and most scientists -thought of matter as continuous. Although since ancient times somephilosophers and scientists had speculated that if matter were brokenup into small enough bits, it might turn out to be made up of verytiny atoms, few thought the existence of atoms could ever be proved.Today we have imaged individual atoms

What is space?For millions of years, space was out of reach for humans stranded hereon planet Earth. Like any inaccessible object, it was much dreamedabout and inspired many different interpretations. Indeed, forcenturies the heavens were believed to be the realm of the godsbathing in everlasting happiness.Humans had to find out the truth, and the only way was to see thingsfor themselves. When

Some call it space trash, others refer to it asspace junk or space debris. All three terms identify the same items --man-made objects remaining in space though they no longer serve anyuseful purpose.

Einstein’s fallacies

Einstein's fallaciesEinstein's relativity theory is a central plank of 20th-century science and is commonly said to have passed every experimental test with flying colours. However, there are plausible alternative explanations for all the experimental data and astronomical observations currently cited in support of the special and general theories of relativity, and the internal inconsistencies

Big bang fantasies

2006-10-28T15:35:00.001+05:30

Big bang fantasiesLogic and common sense dictate that nothing can come from nothing, and that nothing can be annihilated into nothing; energy-substance can only be transformed. Furthermore, nothing finite can become infinite or infinitesimal, and nothing infinite or infinitesimal can become finite. Space is infinite if the multitudes of finite, concrete systems within it, and in fact composing it

Theosophical relativity

Theosophical relativitySpace is commonly thought of as being absolute emptiness or nothingness. However, if space were sheer nothingness, it would not exist, and nothing could be located in it or move through it. Logically, space must have some kind of structure and therefore consist of substance, and unless this substance is assigned impossible, abstract properties (such as absolute continuity

I shall take this to include the human race, even though much of its behaviour through out history, has been pretty stupid, and not calculated to aid the survival of the species. Two questions I shall discuss are, 'What is the
