Interstellar Travelers of the Future May be Helped by MU Physicist’s Calculations

University of Missouri’s Sergei Kopeikin may have solved the Pioneer anomaly

COLUMBIA, Mo. – Former President Bill Clinton recently expressed his support for interstellar travel at the 100 Year Spaceship Symposium, an international event advocating for human expansion into other star systems. Interstellar travel will depend upon extremely precise measurements of every factor involved in the mission. The knowledge of those factors may be improved by the solution a University of Missouri researcher found to a puzzle that has stumped astrophysicists for decades.

“The Pioneer spacecraft, two probes launched into space in the early 70s, seemed to violate the Newtonian law of gravity by decelerating anomalously as they traveled, but there was nothing in physics to explain why this happened,” said Sergei Kopeikin, professor of physics and astronomy in MU’s College of Arts and Science. “My study suggests that this so-called Pioneer anomaly was not anything strange. The confusion can be explained by the effect of the expansion of the universe on the movement of photons that make up light and radio waves.” (more…)
