The proposed orbit of Planet Nine looks like it falls in a gap between the heliopause and the Oort cloud; could planet Nine have caused the gap? Would Planet Nine get most of it's energy (electro-magnetic) from extra solar sources, since it is outside the heliopause?

2/2 is one, pardon the ignorance but I instruct my students to learn mathematics, the greatest abstraction ever discovered by the mind of humanity is mathematics! I didn't get that piece of the pie. I can paint or draw anything but what is that when you can argue about the real meaning of one...

Let me rephrase my last question, of course they are not the same, the whole universe operates in a vacuum; what I meant to ask was; would an area of space with mass --> zero affect the vacuum? In the great voids between the galaxies is the vacuum affected by the absence of matter?

I looked at the discussions about the "rubber sheet." I need to get another concept right. GR talks about flat space, quantum physics talks about the vacuum; both would be low mass but they are not the same thing, right?

Thank you and I will look up the problems involved in the "rubber sheet" view of space-time.

My name is Blayde, and I teach art. I am very interested in creating images and animations that help people visualize science. Past 4 dimensions it gets really hard make visual sense of concepts.

In general relativity what happens when two masses approaching zero, are separated by a distance approaching infinity? Is there a condition in general relativity where a lack of mass can warp space-time up instead of a massive object putting a dent in it? I think I am asking what happens to GR...
