t. e. In cosmology, the cosmological constant (usually denoted by the Greek capital letter lambda: Λ ), alternatively called Einstein's cosmological constant, is the constant coefficient of a term that Albert Einstein temporarily added to his field equations of general relativity. He later removed it; however, much later it was revived and ...
Hinduism portal. v. t. e. Hindu cosmology is the description of the universe and its states of matter, cycles within time, physical structure, and effects on living entities according to Hindu texts. Hindu cosmology is also intertwined with the idea of a creator who allows the world to exist and take shape. [ 1]
Tirumala Tirupati Devasthanams ( TTD) is an independent government trust in India which manages various temples, including the Tirumala Venkateswara Temple in Andhra Pradesh. The trust oversees the operations and finances of the richest and the most visited religious center in the world. [ 1] It is also involved in various social, religious ...
Category. v. t. e. The characterization of the universe as finely tuned intends to explain why the known constants of nature, such as the electron charge, the gravitational constant, and the like, have their measured values rather than some other arbitrary values. According to the "fine-tuned universe" hypothesis, if these constants' values ...
Width. 26.2 ft (8.0 m) Elevation. 9.8 ft (3.0 m) Natural Arch, Tirumala hills, a notified National Geo-heritage Monument, [ 1][ 2][ 3] is a distinctive geological feature 1 km (0.6 mi) north of the Tirumala hills temple, near the Chakra Teertham in Tirupati district in the state of Andhra Pradesh, India. The arch is also called Silathoranam ...
In cosmology, the cosmological constant problem or vacuum catastrophe is the substantial disagreement between the observed values of vacuum energy density (the small value of the cosmological constant) and the much larger theoretical value of zero-point energy suggested by quantum field theory . Depending on the Planck energy cutoff and other ...
Primordial fluctuations are density variations in the early universe which are considered the seeds of all structure in the universe. Currently, the most widely accepted explanation for their origin is in the context of cosmic inflation. According to the inflationary paradigm, the exponential growth of the scale factor during inflation caused ...
Physical cosmology is a branch of cosmology concerned with the study of cosmological models. A cosmological model, or simply cosmology, provides a description of the largest-scale structures and dynamics of the universe and allows study of fundamental questions about its origin, structure, evolution, and ultimate fate.
