We investigate the effects of light-cone fluctuations over the renormalized vacuum expectation value of the stressu2013energy tensor of a real massless minimally coupled scalar field defined in a (d+1)-dimensional flat spaceu2013time with topology ${mathcal R}times {mathcal T}^d$. For ...
Assuming that any detectable technosignature must be within the bounds of our past “light cone” (the path that light from any single event would take through space–time), theoretical astrophysicist and astrobiologist Amedeo Balbi of the University of Rome Tor Vergata in Italy has derived some...

When it comes to particle physics, however, much of the action takes place in giant accelerators smashing particles together at the speed of light. These accelerators are sometimes humanmade and therefore live on Earth — other times, they're of the cosmic sort and exist in deep space. Indeed...
The world-volume section condition in (4.24), V = ηmn∂m∂n = 0, is solved analogously in the lightcone gauge ∂+ ̸= 0 , ∂m = 0 for m ̸= +. (4.35) Then the Gauß law constraint in (4.24), ∂mγmµνPµ = 0, is solved as γ−P = 0 ⇒ P+P...

In practice, all event horizons appear to be some distance away from any observer, and objects sent towards an event horizon never appear to cross it from the sending observer's point of view (as the horizon-crossing event's light cone never intersects the observer's world line). 實際上...
