UNDERSTANDING THE WORMHOLE

Ever since the theory was first put forth in the early twentieth century by scientists Albert Einstein and Nathan Rosen, many have speculated what the ultimate implications of the theory of relativity could mean. We imagine it as a shortcut or cosmic detour through unimaginable distances.

Yet, it’s not without risks: from radiation to immanent collapse, et al interstellar horrors make even the idea of wormhole travel a harried venture at best. The mathematics behind the theorized wormholes predicts such a phenomenon, but as of yet there have been no scientific discoveries or research to indicate any wormhole’s presence.

We also shouldn’t mistake a cosmic shortcut for a means of time travel. It is meant simply to help get to a destination faster. Even Stephen Hawking has said that wormholes are probably not capable in assisting our will to time travel. Sorry, Interstellar fans.

THE RECENT FUROR IN SCIENCE

It’s no surprise that studying such an interesting scientific phenomenon has generated such widespread attention. After all, so many of us are eternally on the lookout for some way to time travel, whether by gadget or plot device (i.e., fate).

But recent research released by the journal Nature does involve wormhole theory but approaches it in a different way than what Einstein had envisioned.

The study presents to the scientific community and the public the idea of studying a wormhole via magnetism. What was proposed was last seen in an earlier study in 2007 in the journal Physical Review Letters, which described a type of wormhole capable of being invisible, or cloaking.

A STEP FURTHER INTO THE STUDY

But new research has taken a slightly different avenue, keeping the idea of a magnetic wormhole to the fore. The study approached the magnetic wormhole through the use of superconductors, constructing a model in the form of a three layered object.

What the combined models would accomplish is to create a wormhole that’s magnetically cloaked, making any object traveling through it invisible as soon as it enters, giving the impression upon exit of seemingly popping out of nowhere on the other side. To understand this better, imagine approaching a tunnel in a mountain, suddenly disappearing from one end, and then popping back into existence at the other end.

Though the study proves the existence of wormholes in terms of magnetic interaction, there is no way to verify the existence of wormholes in space. However, the use of this magnetic wormhole technology would be both profound and exceedingly practical.

Magnetic Wormhole Discovered

A less chaotic, more orderly moving molecular world is strange to consider. - http://clapway.com/2015/06/15/on-molecular-motion-freezing-cold-molecules-123/

If you’ve never thought about the temperature of molecules, these MIT researchers will have changed that fact. Cold molecules are now a plaything in MIT’s laboratory. In successfully cooling a gas of sodium potassium (NaK) molecules to a temperature of 500 nanokelvin (only a hair above absolute zero), they have done it — they have proven the theory griping scientists for decades.

The Molecular Motion Theory

Molecules surround us, in matter and space, in constant motion and interaction with one another. They move extremely fast, too. This is true of molecules at temperate temperatures. However, researchers have long suspected that if they were to be able to cool the temperature of a molecule to nearly absolute zero, the new cold molecules would subdue in a screeching halt, no longer frenzied in motion. The idea is that they would actually move more unanimously.

A Union of Cold Molecules

A less chaotic, more orderly moving molecular world is strange to consider. It’s so foreign because the reality is so different. No surprise there as collisions with other molecules were way less likely in their less frenzied, slowed motions. According to Physicists at MIT,  molecules “exhibited very strong dipole moments — strong imbalances in electric charge within molecules that mediate magnet-like forces between molecules over large distances.”

A professor in the physics department, Martin Zwierlein believes that with knowing normal temperature molecules are brimming with high energy, and the cold molecules become steadied, brings us closer to finding out the temperatures where quantum mechanics interacts hugely with the motion of molecules. In that case, these sodium potassium molecules would move like matter waves rather than randomly frenetically. Researchers have published their findings in Physical Review Letters.

Sodium Potassium (NaK) Molecule Dumbbell

Every single molecule — even the simples of them — is made up of atoms bonded to form its structure. Imagine a dumbell with the weights on either end representing individual atoms. The bar is the bond that holds the structure together. At simplest, they are held together by electromagnetism. MIT researchers tested on and cooled sodium potassium (NaK) molecules. NaK’s structure included a single sodium atom and a single potassium atom.

How To Cool Molecules

It is easier to make cold molecules that have a simple sort of form, imaginably (they move so freely). The tools the MIT research team used included a cooling laser to evaporatively cool cloud of individual sodium and potassium atoms. They were then made to bond using an electromagnetic field. They did this with a Feshbach resonance.

The Feshbach resonance technique was invented by another MIT physicist named Herman Freshbach. It creates a rather weak bond, however. The MIT team strengthened the bond with another technique again involving lasers. It was with this technique they were able to bring down the temperature and frenetic movement to its lowest. The cold molecules were now relatively chemically stable, especially in their kinetic energy state. The sodium potassium (NaK) molecule gas turned out to be quite stable. Zweirlein says that now we’re at 500 nanokelvins and this is already an accomplishment. With that, 10 degrees colder is an ideal for the future.
