- Semiapies 17y agoAs per my response here: http://news.ycombinator.com/item?id=1205011 http://news.ycombinator.com/item?id=1205011 You have it backwards - you can justify throwing absolute value into the equation if you actually find find evidence that negative mass is just as hard to accelerate as positive mass.
- roundsquare 17y agoWell look, no one has seen negative mass objects (as far as we know). All he's saying is that this is one way to fix the F = ma equation to deal with negative mass. I agree that the burden of proof is on him or anyone who wants to run with the idea, but for now its just being proposed as neat, possible idea. You're reading a speculative blog entry as if it were a rigorous scientific paper and then claiming that he hasn't done the science.
- Semiapies 17y agoNo, I'm pointing out that, contra phaedrus, the concern is not "answered", but instead handwaved. And when someone starts telling stories about a "well-known astronomer" who has substantiated his hypothesis, he's taken his claim to a higher level than "a neat, possible idea".
