Sara Imari Walker is an American theoretical physicist and astrobiologist with research interests in the origins of life, astrobiology, physics of life, emergence, complex and dynamical systems, and artificial life.
Lawrence Maxwell Krauss (born May 27, 1954) is a Canadian-American theoretical physicist and cosmologist who taught at Arizona State University (ASU), Yale University, and Case Western Reserve University. He founded ASU's Origins Project in 2008 to investigate fundamental questions about the universe and served as the project's director.
In modern physical cosmology, the cosmological principle is the notion that the spatial distribution of matter in the universe is uniformly isotropic and homogeneous when viewed on a large enough scale, since the forces are expected to act equally throughout the universe on a large scale, and should, therefore, produce no observable inequalities in the large-scale structuring over the course ...
Cosmology. Physical cosmology – origin and evolution of the universe as a whole. The study of cosmology is theoretical astrophysics at its largest scale. Chemical cosmology - study of the chemical composition of matter in the universe and the processes that led to those compositions.
To quantify the potential amounts of life in biospheres, theoretical astroecology attempts to estimate the amount of biomass over the duration of a biosphere.The resources, and the potential time-integrated biomass were estimated for planetary systems, for habitable zones around stars, and for the galaxy and the universe.
Davies' research interests are theoretical physics, cosmology and astrobiology; his research has been mainly in the area of quantum field theory in curved spacetime.His notable contributions are the so-called Fulling–Davies–Unruh effect, [4] according to which an observer accelerating through empty space will be subject to a bath of induced thermal radiation, and the Bunch–Davies vacuum ...
Illustration of the analogy between the human body and a geocentric cosmos: the head is analogous to the cœlum empyreum, closest to the divine light of God; the chest to the cœlum æthereum, occupied by the classical planets (wherein the heart is analogous to the sun); the abdomen to the cœlum elementare; the legs to the dark earthy mass (molis terreæ) which supports this universe.
Black holes have a role in natural selection. In fecund theory a collapsing [clarification needed] black hole causes the emergence of a new universe on the "other side", whose fundamental constant parameters (masses of elementary particles, Planck constant, elementary charge, and so forth) may differ slightly from those of the universe where the black hole collapsed.
