A New Theoretical Model for time travel being imagined

Technion Israel Institute of Technology researchers have developed a theoretical model of a time machine that, in the distant future, could possibly enable future generations to travel into the past. An article on this research was published last week in the scientific journal Physical Review.

By tweaking Einstein’s space time and general relativity models these researchers are becoming more confident with the idea of travelling back in time, something that most scientists believe to be improbable because of the paradoxes and other reasons that could happen if one did so. Curving space time, as is the basis for wormholes to travel instantaneously from one point in space to another, is the basis for this research. So instead of going to another space point in your time, you go from your point in time to another point in time.

Atom scale teleportation on the verge of reality

A recent Engadget article suggests that a team of Australian physicists have come up with a simple-sounding method of teleporting atoms by bringing the matter to near absolute zero temperatures. This doesn’t seem feasible for humans yet but maybe it could be for non-living matter (supplies, goods, etc) in the near future!

Man was Gene Roddenberry (Star Trek creator) way ahead of his time!

Look mom no more wires : Wireless Power Transfer

A team from MIT call this wireless power transfer invention ‘WiTricity’ and believe it could change the way we use electricity and do away with the tangle of cables, plugs and chargers that clutter modern homes.

I predicted that this technology could be feasible one day when I was doing my bachelor’s in electrical engineering back in the 90’s.

Discovery of water on extra-solar planet

An artist’s impression of the transiting exoplanet (credit: ESA) Using NASA’s Spitzer Space Telescope and transit analysis in the infrared spectrum, a gas giant of the size of Jupiter has spectral properties which scientists conclusively confirmed that water vapour exists in the sphere. Although the chance of life as we know it on the planet is improbable as the orbit is very close to the star.

Professor proposes theory of unparticle physics

Credit: Benoit Mandelbrot, Fractals. Howard Georgi, a physicist at Harvard University, has recently published a paper on so-called unparticle physics, which suggests the existence of ‘unparticle stuff’ that cannot be accounted for by the standard model. Appearing in a recent edition of Physical Review Letters, the paper says that unparticle stuff would be very different than anything seen before.

Unparticles, but not particles, can fit in a theory that has the property of continuous scale-invariance, which is difficult to visualize. A fractal, like this Koch Curve, is an example of discrete scale-invariance because it looks the same if multiplied by a fixed number. Credit: Benoit Mandelbrot, Fractals.

New Quantum Communication record : 90 miles

In Spain’s Canary Island chain, researchers from all over Europe generated a polarization-entagled photon pair with the twin sent over an optical free-space link to Tenerife about 144 kilometers (90 mi) away where the Ground Station of the European Space Agency acted as a receiver. Previously 13km was the record on similar experiments. Quantum Entanglement

Quantum entanglement is a property of particles, such as photons, to become entangled with each other, behaving like psychically connected twins. Even at vast distances a disturbance on one affects the other. This was even predicted and labelled “spooky interaction” by Albert Einstein himself.

If this technology continues on these records, we could be seeing satellite-based quantum communication and experiments on quantum physics in space in addition to ubiquitous instantanenous communication across light years. Think of the instantaneous communication in the Star Trek TV shows over many light years.

The physics missing link ? More dimensions of Time ?!?

With the vast number of physicists attempting to prove String and M-Theory, there are a few who believe the reason why those two theories will prove elusive to confirm is because there are possibly more than one dimensions related to Time. So you’re probably thinking that this is way out there, and I do agree. I try to keep up to date on such scientific news due to the fact that these ideas represent the thoughts of many who believe that there is more than just the laws that we know. In a way Bhuddist scholars and philosophists have been insisting this for long time, like Alan Watts. Understanding things or everything, in my opinion, is the very implication of Bhuddist and other eastern philosophies.

By trying to understand more than just what we see, in a way we come closer to understanding our own nature as in the fact that our own materialistic bodies and objects derive from this universe we live in.

And whether it’s a Bhuddist monk or a world reknowned applied physicists, why shouldn’t we seek to gain knowledge. Gaining knowledge has improved the quality of our lives throughout time, seeking this physical knowledge and even deeper spirituality should be at the core of all of us, regardless of what faith you follow, it’s universally applicable. Hopefully in our own evolution we can seek knowledge in peace and harmony rather than violence and chaos (another core idealogy from eastern philosophies).

2 Billion Year Old Cluster Collision proves Dark Matter exists

NASA: Hubble Telescope Finds Ring of Dark MatterUS Astronomers using NASA’s Hubble Space Telescope have been observing a star cluster CL0024+17 which is approximately 5 billion light years from Earth and running repeaded simulations to show that the observations yield the best proof to date of the existance of dark matter. Dark matter, a mysterious substance believed to make up more than a quarter of the universe and is suspected to be the glue that holds entire gallaxies together, is usually impossible to see directly. Light bending measurements from areas suspected of dark matter in the past have given indirect proof of dark matter. Now scientists believe they have lucked out with the perfect timing.

String Theory – So is it just a Thoery or could it be real ?

String Theory has been the dream of many post-Einstien scientists and theoretical physicists to try to combine Einstein’s world of the large (planets, galaxies, the universe) with the ideas of the quantum world of the small (uncertainty principle, subatomic particles) into one unifying law that can describe absolutely everything that we see and even things that we can’t see or understand yet. String Theory also inevitably yields bigger theories such as parallel universes, M-Theory An artist's impression of a Calabi-Yau manifold. Made for Nova.and even tries to explain away how the Big Band happened and what happened before it.

If you’ve ever studied physics in school, you probably remember how many times you had to learn new theories, laws, formulas, axioms and equations. Well what if you only had to learn one law that could explain away all these other things (at least as an abstract base) ? This is the goal of String Theory.

To get a more detailed understanding of what String Theory is, check out this excerpt from Wikipedia.org :

String theory is a model of fundamental physics whose building blocks are one-dimensional extended objects called strings, rather than the zero-dimensional point particles that form the basis for the Standard Model of particle physics. The phrase is often used as shorthand for Superstring theory, as well as related theories such as M-theory. String theorists are attempting to adjust the Standard Model by removing the assumption in quantum mechanics that particles are point-like. By removing this assumption and replacing the point-like particles with strings, it appears that a sensible quantum theory of gravity naturally emerges. Moreover, string theory may be able to “unify” the known natural forces (gravitational, electromagnetic, weak nuclear and strong nuclear) by describing them with the same set of equations.

A recent article on New Scientist magazine states that experiments performed at the upcoming Large Hadron Collider (LHC) in Geneva, Switzerland could possibly disprove the popular “theory of everything”. So far it’s been very difficult to prove this theory, as indirect evidence that scientists from all parts of the world have been looking for has not been found yet.

The LHC will smash protons together and could prove or maybe even disprove string theory The LHC will smash protons together and could test string theory (Illustration: LHC/FNAL) altogether. Strong evidence for string theory could come from the observation of short-lived, mini black holes at the LHC. But the chance of their appearing is extremely small, so a failure to see them would not be a death blow for the theory.

In 2006, string theorist Allan Adams of MIT and others offered a more promising check. They showed that some particle collisions could reveal whether certain fundamental assumptions underlying string theory are wrong.

Now, a team led by Jacques Distler from the University of Texas in Austin has shown that the level of energy needed to reveal such effects are achievable at the LHC.

Lockheed Martin subsidiary on the verge of sustainable fusion

Extensive computer simulation and real tests have been underway at the Sandia National Laboratories on the device called the ‘Z Machine’ which is the world largest producer of man-made X Rays and has been used to produce fusion neutrons. Rapid bursts (in the nano second range) are necessary for future generating plants to produce electrical power from sea water. This had not been thought achievable till now.

The researchers and scientists have been able to achieve successful nanosecond bursts with the invention of a new system called a linear transformer driver (LTD), which was created by researchers at the Institute of High Current Electronics in Tomsk, Russia, in collaboration with colleagues at Sandia.

The LTD technology is 50 percent more efficient than current Z machine firings, in terms of the ratio of useful energy out to energy in. Z is currently 15 percent efficient to its load (already a very high efficiency among possible fusion machines).

Funding for Z in the past has been for defense purposes. Its tests are used to generate data for simulations on supercomputers that help maintain the strength, effectiveness, and safety of the US nuclear deterrent.

Fired repeatedly, the machine could well be the fusion machine that could form the basis of an electrical generating plant only two decades away. Progress in this arena might eventually require funding from DOE’s energy arm.

The Sandia Lab has filed a patent application on a high-power pulsed-power accelerator that can use an LTD as the primary power generator.

If this technology is succesful over the next five years, we could be on the brink of a technology revolution and a safer path towards keeping our planet cleaner.
