Also known as the "Pioneer effect" (the unexpected and sudden alterations to Pioneer 10 and Pioneer 11 trajectories measured as they continue their journey into the outer solar system), similar anomalies are being seen in flybys by modern space probes. Earth flybys by Galileo, Rosetta, NEAR and Cassini have all experienced a sudden boost in speed. After cancelling out all possible explanations, including leakage of fuel and velocity measurement error, a new study suggests the answer may lie in a bizarre characteristic of universal physics…<br /><br />Planetary flybys are an essential aid to interplanetary missions to gain energy as they accelerate on their merry way to their destination. Gravity assists are accurately calculated by mission scientists so the time of arrival can be calculated down to the minute. Considering most missions take years to complete, this degree of accuracy is amazing, but essential.<br /><br />So, when Galileo completed gravity assist past Earth on December 8, 1990, to speed it toward Jupiter, you can imagine NASA's surprise to find that Galileo had accelerated suddenly, and for no apparent reason. This small boost was tiny, but through the use of the Deep Space Network, extremely accurate measurements of the speeding craft could be made. Galileo had accelerated 3.9 mm/s.<br /><br />This isn't an isolated case. During Earth flybys by the space probes NEAR, Cassini-Huygens and Rosetta, all experienced a unexplained bo</p></blockquote> <div class="Discussion_UserSignature"> </div>

At some point might we deliberately send atomic clocks on these trajectories to ascertain the rate of change of the radius of the universe ??<br /><br />Is the Unruh effect like an impedance mismatch on an antenna (SWR) and if you 'tweak' the length of the antenna a tiny tiny bit, suddenly everything starts working ??<br /><br /><br /><br /> <div class="Discussion_UserSignature"> <p><font color="#ff0000"><strong>TPTB went to Dallas and all I got was Plucked !!</strong></font></p><p><font color="#339966"><strong>So many people, so few recipes !!</strong></font></p><p><font color="#0000ff"><strong>Let's clean up this stinkhole !!</strong></font> </p> </div>

WOW.<br /><br />Any thoughts on practical applications?<br /><br />Bob

The effect is small so not likely, but it should allow for better distance/speed calculations for missions from here on....presuming it pans out. <div class="Discussion_UserSignature"> </div>

There's an error in universetoday article - according to that theory vacuum radiation is the cause of inertia, and when wavelength becomes too large to "notice" - inertia decreases. So boost would be caused by very small acceleration, not an increase in acceleration.<br /><br />On the other hand the original arxiv article is not very meaningful. They seem to deliberately choose constants and centers to fit with observations and dismiss anomalies which still don't fit without any explanation at all.
