From Wikipedia ![]() We as observers can still signal different parties and places as long as we live within their "past"lightcone. From Wikipedia ![]() There is also a stability assumption which restricts the spectrum of the four-momentum to the positivelightcone(and its boundary). From Wikipedia ![]() Alightconerepresents any possible future evolution of an object given its current state, or every possible location given its current location. From Wikipedia ![]() Lightconecoordinates are sometimes used to describe relativistic collisions, especially if the relative velocity is very close to the speed of light. From Wikipedia ![]() In the latter, not all points are causally related, but only those for which one point falls within thelightconeissuing from the other. From theCambridge English Corpus No such refinement is necessary for the passage from 'before' to 'at' since 'enter', 'at' and 'exit' all coincide there, this being the apex of thelightcone. From theCambridge English Corpus In curved spacetimes thelightconewill be tilted along the spacetime's geodesic.

From Wikipedia ![]() Worldlines of light form the boundary of thelightcone. From Wikipedia ![]() A more significant notion is absolute future or the futurelightcone. From Wikipedia ![]() The southwest corner of the intersection would also include an oculus for alightconeabove the platform. From Wikipedia ![]() As the island is well outside thelightconeof coastal cities, the stargazing is spectacular, with nightly meteor showers not uncommon. From Wikipedia ![]() To obtain a fully fixed gauge, one must add boundary conditions along thelightconeof the experimental region. From Wikipedia ![]() A similar process led to the construction of thelightconeas a characteristic surface for the wave equation. From Wikipedia ![]() But we can not receive signals from those parties and places outside our "past"lightcone. From Wikipedia ![]() These examples are from corpora and from sources on the web.
