Relativity in the Global Positioning System
The Global Positioning System (GPS) uses accurate, stable atomic clocks in satellites and on the ground to provide world-wide position and time determination. These clocks have gravitational and motional frequency shifts which are so large that, without carefully accounting for numerous relativistic effects, the system would not work. This paper discusses the conceptual basis, founded on specia...

15 صفحه اولOn Existence of Static Metric Extensions in General Relativity
Abstract: Motivated by problems related to quasi-local mass in general relativity, we study the static metric extension conjecture proposed by R. Bartnik [4]. We show that, for any metric on B̄1 that is close enough to the Euclidean metric and has reflection invariant boundary data, there always exists an asymptotically flat and scalar flat static metric extension in M = R \B1 such that it satis...
متن کاملThe Global Existence Problem in General Relativity
We survey some known facts and open questions concerning the global properties of 3+1 dimensional space–times containing a compact Cauchy surface. We consider space–times with an l–dimensional Lie algebra of space–like Killing fields. For each l ≤ 3, we give some basic results and conjectures on global existence and cosmic censorship. For the case of the 3+1 dimensional Einstein equations witho...
متن کاملA Cosmological Test for General Relativity
The latest results in cosmography as well as the latest observations of the cosmic microwave background (CMB) and of supernovae have reinforced the emergence of a canonical paradigm for cosmology. Most of the cosmological parameters constituting this concordance model are now known up to five per cent of relative accuracy. We can rely on these accurate values of the parameters if the fundamenta...
