Graduate Tachyons travel backward in time?
So in an imaginary negative energy "anti"world a signal would go backwardtime to the sender of the photon that came here. That would make a "real time" loop.?- heskam

Graduate Is String Theory Still the Best Path to a Unified Theory of Everything?
Strings? I personally think duality is the number 1 idea from that direction. Those octonion electrogravity http://front.math.ucdavis.edu/author/Z.Weng things seems interesting to me. Maybe we really are seeing inside when looking outside...- heskam

Graduate Negative Mass: Possibility of FTL Travel?
How can you say that a point has physical meaning? I would put at least equal mass for i as for a point. Wiki: "Spontaneous symmetry breaking describes the case where the laws are invariant but it appears the system isn't because the background of the system, its vacuum, is noninvariant...- heskam

Graduate Negative Mass: Possibility of FTL Travel?
imaginary fields Why can't we dualize our "physical" world? For example imaginary gravitational field would (in my thinking) produce attraction with equal signs and repelling with opposite signs. Still there might be some "covariance" between real ("physical") and imaginary worlds: if a mass...- heskam

Undergrad Is Our Universe Infinite or Spherical?
Lightcone? Isn't it rather a lightprojective space! We live in Simultaneoucity. Sure not infinite. Light identificates points in time. We have an idea that after approksimately 8 minutes we find sun in that position where calculated. -

Undergrad Two vectors in 3D, always form a plane?
Vector is an equivalence class. So you can pick a representative from any place in a space. Two vectors don't form a space, you need a whole bunch of their linear combinations to form a plane unless they are equal or opposite in direction (zerovector has whichever direction). Vectors don't...- heskam
