revolution theoreticians have declared contending and approximately incompatible theories, caused in bewilderment among concerned field enthusiasts. as a result, some have intended to categorize these theories till reduce bewilderment, and make them easier to study. one of these theoreticians is jack goldstone who at first categorized theories of revolution into three generations. but after the...

While recent gravitational wave observations by LIGO and Virgo allow for tests of general relativity in the extreme gravity regime, these are still blind to a large swath phenomena outside instruments' sensitivity curves. Future gravitational-wave detectors, such as LISA, will enable probes longer-duration lower-frequency events. In particular, LISA characterization non-linear dynamics mass-rat...

We study the retarded field sourced by a uniformly accelerated particle in nonlocal scalar theory. While presence of nonlocality regularizes at location source, we also show that Lorentz-invariant theories are particularly sensitive to somewhat unphysical assumption uniform acceleration, leading logarithmic divergences on acceleration horizon. Analytic properties Green function indicate can be ...
