چکیده
In this paper, we present an accelerating cosmological model by constraining the free parameters using datasets in extended symmetric teleparallel gravity for flat and anisotropic space-time. We employ a time variable deceleration parameter that behaves early late acceleration form of Hybrid Scale Factor (HSF). obtain values analyse behavior Universe based on best-fit parameters. derive dynamical equation state at quintessence region; however it approaches to $\Lambda$CDM. The energy conditions are also analysed validate modified find strong condition is violating. establish importance hybrid scale factor cosmic phenomena issue.

Scale-invariant gravity: Spacetime recovered
The configuration space of general relativity is superspace the space of all Riemannian 3-metrics modulo diffeomorphisms. However, it has been argued that the configuration space for gravity should be conformal superspace the space of all Riemannian 3-metrics modulo diffeomorphisms and conformal transformations. Recently a manifestly 3-dimensional theory was constructed with conformal superspac...
متن کاملEinstein - Æther Gravity : Theory and Observational Constraints
Einstein-aether theory is general relativity coupled to a dynamical unit timelike vector field. A brief review of current theoretical understanding and observational constraints on the four coupling parameters of the theory is given.
متن کاملProbing Gravity with Spacetime Sirens
A gravitational observatory such as LISA will detect coalescing pairs of massive black holes, accurately measure their luminosity distance and help identify a host galaxy or an electromagnetic counterpart. If dark energy is a manifestation of modified gravity on large scales, gravitational waves from cosmologicallydistant spacetime sirens are direct probes of this new physics. For example, a gr...
متن کاملSpacetime in Semiclassical Gravity
This article will summarize selected aspects of the semiclassical theory of gravity, which involves a classical gravitational field coupled to quantum matter fields. Among the issues which will be discussed are the role of quantum effects in black hole physics and in cosmology, the effects of quantum violations of the classical energy conditions, and inequalities which constrain the extent of s...
متن کامل3D gravity data-space inversion with sparseness and bound constraints
One of the most remarkable basis of the gravity data inversion is the recognition of sharp boundaries between an ore body and its host rocks during the interpretation step. Therefore, in this work, it is attempted to develop an inversion approach to determine a 3D density distribution that produces a given gravity anomaly. The subsurface model consists of a 3D rectangular prisms of known sizes ...
