Searching for Tachyons (continued)

Gravity and Superstrings

In the final portion of the chapter on tachyons, Tiwari writes: "Recent advances in tachyon physics (in the theoretical domain) originate in quantum electrodynamics in the presence of gravity, and tachyons in superstring theories. Faster-than-light photon propagation due to vacuum polarization effects in a background gravitational field was discovered by Drummond and Hathrell in 1980 [Citation: Physical Review D, #22, page 343.]. On the other hand tachyons have been known to arise from early times in bosonic
strings -- both closed and open; their importance in recent years has been due to the developments in the brane theory and non-perturbative techniques in string theory."

He then explains superluminal photons (based on the given citation), noting that the framework that results from combining Quantum Electrodynamics (QED) and STR "has been very successful" at explaining the electromagnetic interactions...
