Named by Feinberg in 1967, earlier works by Sommerfeld, Sudarshan, Bilaniuk and Deshpadne described them.
The Sen conjecture concerns condensation of these as regards D-branes. Named by Feinberg in 1967, earlier works by Sommerfeld, Sudarshan, Bilaniuk and Deshpadne described them. Able to be detected through Cherenkov radiation but only found on the space-like area of an energy-momentum graph, special relativity implies that these theoretical spinless particles could be used to communicate with the past using a namesake "anti-telephone." Possessing space- like four-momentum, imaginary proper time and accelerating as they lose energy, they never slow below c. For 10 points name these items named for the Greek for "swift," which travel faster than the speed of light.
