In September 1998 astrophysicists documented an inexplicable “tug” acting on the now defunct Ulysses spacecraft as it traveled through the Solar System in an orbit over the Sun’s poles. When radio signals from Earth were returned from an onboard transponder, Ulysses exhibited an anomalous acceleration toward the Sun. A Doppler shift in the frequency of the return transmission indicated a variance greater than could be accounted for by known mechanisms—as of today, no one in the conventional science community can provide a solid explanation for it.
NASA scientists also determined that both of the Pioneer spacecraft are off course by more than a hundred thousand kilometers. At this time, there is no explanation for the navigational deviation, so many speculations are offered about what “mysterious” forces could be acting on the most distant of artificial objects. They include: multidimensional bent space, dark energy, and “dark matter friction”. Other ironic theories such as, […]
