"heavier" and "lighter" can refer to density, as Jerry obviously intended. In any case, isn't it a bit of a straw man to use his bad joke to dismiss his ideas?

To me, it makes a lot of sense. That does not make Jerry correct, of course. A lot more math is going to be required to prove that his theory does not contradict observational evidence.

Dismissing an ATM idea out of hand because it does not conform to conventional science is a bad idea when conventional science cannot explain observations. The entire point of the thread is that there is evidence of something unexpected going on to cause the Pioneer anomaly. Plenty of mainstream scientists are looking at ATM ideas to explain it.

Jerry has cited observational evidence that, at first look at least, can plausibly be explained by his theory. Some of this evidence will surely be eliminated by additional research, and it is likely that the basic ideas can be directly contradicted by hard data. However, having read all of Jerry's previous posts, I think it is worth the effort to actually research the evidence rather than simply dismiss him.

Really, have you two even read his posts in ATM? Certainly not carefully enough, if you think he could mistake mass and weight.
