Large Hardon Collider

Oh, I know what I forgot to tell you, the 5 million year journey was a round trip, bringing the ship back to Earth 5 million years in the future.


...despite assumptions made about my knowledge, I do know how relativity works, and that the 5 million years at relativistic velocities on the ship are only 1000 years subjectively for those on board.

This would leave each terminus of the wormhole at Earth, connected across 5 million years, according to the manner in which the wormholes work in the sci-fi universe the story is set in.

This has nothing to do with the thread, but I'm leaving this here:

Ah, you were implying that the start of the wormhole didnt progress forward in time, but was stationary in time, I see.

[Max™]

No, I was implying that the end left on Earth followed a spacetime trajectory which crossed 1000 years while the other end wound up on Earth 5 million years later after a subjective 1000 years.

AD 5,000,000 (4951 subjective date aboard the ship): ship arrives back in Earth orbit, someone goes through this end, they follow a trajectory connected to 4951 AD, someone from 4951 AD goes through their end, they follow a trajectory connected to 5,000,000 AD.

Kip Thorne's Wormholes

In 1985, cosmologist Kip Thorne was asked by science popularizer Carl Sagan to devise a hypothetical traversible wormhole. Thorne and his collaborators then created what was a remarkably simple solution that would in theory connect two periods in time. The wormhole would not rip its occupants apart, would stay open for the duration of a trip through, would not freeze its occupants inside, and would not create time paradoxes. However, it would require a never-observed form of exotic matter whose total energy is negative.
Based on this solution, Thorne later made the first scientifically sound - though not technically feasible - proposal for the design of a machine for time travel. In one version of his time machine, a chamber containing two parallel metal plates is placed on a rocket ship and accelerated to near-light velocities. An identical chamber, with the time traveler inside, is placed on earth. The electrical field created by the plates (the Casimir effect) creates a tear in spacetime. Since the clocks in the two chambers are ticking at different rates due to relativistic effects, the traveler is hurtled into the past or the future.

I'm pretty sure you guys are missing the point: there are parasailing donkeys.

[Max™]

I'm sorry, I didn't comment on the parasailing donkey, which is actually hilarious... except for the donkey I'm sure.

Incidentally, July 22-28 is the 35th International Conference on High Energy Physics, so if there's interesting news to be had, it'll be had later this week.

Fascinating:

Fourth Property of Electrons? Electric Dipole Moment Would Explain Creation of Universe

ScienceDaily (July 20, 2010) — Electrons are negatively charged elementary particles. They form the shells around atoms and ions. This or something similar is what you will find in text books. Soon, however, this information may have to be supplemented.
The reason is that many physicists believe that electrons have a permanent electric dipole moment. An electric dipole moment is usually created when positive and negative charges are spatially separated. Similar to the north and south poles of a magnet, there are two electric poles. In the case of electrons, the situation is much more complicated because electrons should not actually have any spatial dimension.

Despite this, an entire range of physical theories that go beyond the standard model of elementary particle physics are based upon the existence of dipole moment. These theories in turn would explain how the universe in the form that we know it could have been created in the first place.

According to prevailing theories, the big bang some 13.7 billion years ago would have had to have created just as much matter as antimatter. Since both obliterate each other, nothing would have remained. In reality, however, more matter than antimatter was actually created. An electric dipole moment of the electron could explain this imbalance.

Up to now, nobody has successfully proven the existence of this assumed tiny dipole moment. Existing methods are simply not sensitive enough. A small piece of ceramic is set to change this soon.

Dr. Marjana Ležaić and Dr. Konstantin Rushchanskii from the Institute of Solid State Physics at Forschungszentrum Jülich and Professor Nicola Spaldin from the University of California in Santa Barbara designed this ceramic, which has very special properties, in a virtual laboratory using the Jülich supercomputer JUROPA. The new europium barium titanate should enable measurements to be 10 times more sensitive than they were in the past. According to the Jülich physicists, "this could be sufficient to find the electric dipole moment of the electron."

As electric moment cannot be directly measured, the physicists are working together with scientists from the American Yale University as well as with Czech research institutions in Prague in order to indirectly prove its existence. The researchers in Yale have developed an experimental setup that uses an extremely sensitive SQUID magnetometer to measure the magnetization of the piece of ceramic in an electric field. Their aim is to demonstrate a change in the magnetization when the electric field is reversed. This would simultaneously be the sought-after evidence that the electric dipole moment exists.

In an electron, an electric dipole can only ever be oriented parallel or anti-parallel to the electron spin. In an electric field, most of the electrons are oriented so that their dipole moment is parallel to the field. Fewer are oriented in the other direction. This should lead to a measurable magnetization. If the electric field is reversed, the dipole moments of the electrons are reversed leading consequently to a simultaneous, measurable change in the magnetization. Without an electric dipole moment, on the other hand, the magnetization would remain unchanged.

"It would have been very difficult to find such a well-suited material by trial and error," said Ležaić. This material must have an unusual combination of properties: a high concentration of magnetic ions, magnetic disorder at temperatures below four degrees Kelvin and a reversible electric polarization. "Our colleagues in Yale who came up with the idea of the measurements and conducted them had already tested different materials. However, a new material with all of the necessary properties can be found faster with the use of theoretical analysis and computer simulations."

Ležaić, as the head of the young investigators group, her group member Rushchanskii, and her cooperation partner Spaldin virtually synthesized and analysed europium barium titanate on the supercomputer in Jülich. To do so, all they needed was its chemical composition and the basic equations of quantum mechanics. From these, they calculated the interaction between individual atoms and electrons and the local magnetic properties. So it was that they found the optimum ceramic.

Team colleagues in Prague have already synthesized and characterized the material in the laboratory and confirmed the properties calculated in Jülich. Only the sought-after dipole moment of the electron remains undiscovered. "Unwanted effects are still inhibiting the measurements," said a disappointed Ležaić. "But we're working intensively on improving the material even further."

Kip Thorne would like to have a word with you.

Except the part bolded doesnt work, as the person on the earth side cant enter the wormhole 1000 years later and come out 5million years later, as 1000 earth years would only net a few years on the space ship. @4951 AD, the person on earth would enter the wormhole and arive on the ship that had only been traveling for a few days.

And Kip Thorne didnt solve reverse time paradoxes, so his solution is also impossible.
