Gravitational lensing, unlike all of the previous effects, distorts the apparent position, and number, of background galaxies. The RSDs measured in galaxy redshift surveys can be used as a cosmological probe in their own right, providing information on how structure formed in the Universe, [ 5 ] and how gravity behaves on large scales.
Gold leaf squares were used on paper, with their edges sometimes left visible. [34] These rooms had rather small windows, and the gold reflected light into the room; ceilings might be decorated the same way. [35] The full background might be in gold leaf, or sometimes just the clouds in the sky. [36] The Rinpa school made extensive use of gold ...
The "axis of evil" is a name given to an unsubstantiated correlation between the plane of the Solar System and aspects of the cosmic microwave background (CMB).It gives the plane of the Solar System and hence the location of Earth a greater significance than might be expected by chance – a result which has been claimed to be evidence of a departure from the Copernican principle.

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.

c. 16th century BCE – Mesopotamian cosmology has a flat, circular Earth enclosed in a cosmic ocean. [1]c. 15th–11th century BCE – The Rigveda of Hinduism has some cosmological hymns, particularly in the late book 10, notably the Nasadiya Sukta which describes the origin of the universe, originating from the monistic Hiranyagarbha or "Golden Egg".
The particle horizon, also called the cosmological horizon, the comoving horizon, or the cosmic light horizon, is the maximum distance from which light from particles could have traveled to the observer in the age of the universe. It represents the boundary between the observable and the unobservable regions of the universe, so its distance at ...

A cosmic ocean, cosmic sea, primordial waters, or celestial river is a mythological motif that represents the world or cosmos enveloped by a vast primordial ocean. Found in many cultures and civilizations, the cosmic ocean exists before the creation of the Earth. From the primordial waters the Earth and the entire cosmos arose.
