Creation Cosmologies and the Pioneer Anomaly
I was just told that Russ Humphreys has written on how Creation cosmologies explain the surprising acceleration of the Pioneer spacecraft. I'm too tired to make much of this (been working on my next post), but from the overview:
The paper itself is here.
If a large volume of empty space surrounds the matter of the cosmos, so that the cosmos can have a centre of mass, then the matter is in a deep gravitational potential ‘well’. If space is expanding and spreading the matter outward, then the depth of the well is decreasing. According to general relativity, especially a new solution of Einstein’s equations derived in the Appendix (which also deals with Birkhoff’s theorem), the decreasing depth continuously shortens ‘radar’ distances within the well, causing the observed apparent acceleration. The magnitude of the anomalous acceleration implies the bottom of the potential well has not yet risen very far above the critical depth for gravitational time dilation. Thus the Pioneer effect supports the essentials of several creationist cosmologies: a centre of mass, expansion of space and recent time dilation.
