Who knows what it could evolve into over time. I doubt that Otto ever envisioned what we have today.
"In 1660, a German experimenter named Otto Von Guericke built the first electric generating machine. He showed that electricity could be transmitted by using a wet string to conduct electricity several feet. "
Or Thales.
"Around 600 BCE, in Greece, a mathematician named Thales discovered that amber rubbed with animal fur attracted light objects."

1. Special RelativityScientists officially announced Friday (Sept. 23) that subatomic particles called neutrinos may be passing the ultimate speed limit, zooming at a velocity faster than light. But according to Einstein's special theory of relativity, nothing can cross this barrier. So either the measurements are incorrect, or physicists must revise many trusted theories. Here are 10 that would be affected.
3. Cause and EffectSpecial relativity states that nothing can go faster than the speed of light. If something were to exceed this limit, it would move backward in time, according to the theory.
The new finding raises all sorts of thorny questions. If the neutrinos really are traveling faster than light, then they should be time travelers. The particles could theoretically arrive somewhere before they departed. Physicists suggest such an ability, if it really existed, could be used to send neutrinos back in time to deliver messages.
5. The Standard ModelEinstein's famous equation E=mc^2 states that energy (E) and mass (m) are equivalent, and can be converted from one to the other by the ratio "c-squared," where c represents the constant speed of light.
The status of the speed of light as the ultimate cosmic speed limit is the reason for its presence in the seminal formula. But if c is not in fact the fastest possible speed in the universe, and things can go faster, this may have to be adjusted in special situations. Perhaps the special speed of neutrinos deserves to win the title of ultimate speed limit instead.
7. NeutrinosString theory is incredibly difficult to test, and there is no proof that it's correct. But if the neutrino measurements are correct, some physicists say string theory may offer the best bet of explaining them.
Perhaps, some physicists have suggested, the neutrinos are not traveling along the straight line we thought they were, but instead were hopping into one of the extra dimensions predicted by string theory, and taking a shortcut to their destination. If they traveled a shorter distance in the measured time, then their actual speed may not have been faster than light.

So neptune, what would you go back in time to see?
