I'm a neurologist. Also a fan of physics in the sense that I enjoy watching it like I enjoy watching baseball but I can't really play either one.

comment Can gravity in principle be made to flow through a “wire”?
Thank you. Is there a way to posit mathematically "negative mass" and model in a theory whether gravity could then be made to flow, if negative mass existed? Don't tachyons have negative mass (excluding the question of whether or not they can actually exist).

comment Can gravity in principle be made to flow through a “wire”?
I see your point but thats not really what I meant. I don't have the physical sophistication to say precisely why it isn't. What I'm imagining is a large mass in region one transmitting its gravitational potential (or its gravity, however it should be phrased) to another region and making, for example, water fall 100 miles away.

Did you mean the volume of the particle itself?

comment What causes ballpoint pens to write intermittently?
Then it's got to be that the ball has small imperfections that prevent it from rolling. That's a testable hypothesis-see if the ball rolls when its in this state.
