Human trafficking, exploitation and modern slavery - the evolution of the prosecution and thinking out of the box. What does it mean to be human?
Can we solve the mystery of who we are by learning more about the brain? Or are we more than the sum total of our neurons? Join Professor John Wyatt as he explores this fascinating and multi-dimensional topic. Great speaker. Very interesting talk. Void is impossible. Plurality and change are products of epistemic ignorance derived from sense experience. Temporal and spatial limits are arbitrary and relative to the Parmenidean whole. Genesis creation narrative. The Earth and the Heavens form a unit within infinite "waters of chaos"; the " firmament " keeps out the outer "chaos"-ocean.
The universe contains only two things: an infinite number of tiny seeds atoms and the void of infinite extent. All atoms are made of the same substance, but differ in size and shape. Objects are formed from atom aggregations and decay back into atoms.
Cosmology - Wikipedia
Incorporates Leucippus ' principle of causality : "nothing happens at random; everything happens out of reason and necessity". The universe was not ruled by gods. Pythagorean universe. At the center of the Universe is a central fire, around which the Earth, Sun, Moon and planets revolve uniformly.
The Sun revolves around the central fire once a year, the stars are immobile. The earth in its motion maintains the same hidden face towards the central fire, hence it is never seen. First known non-geocentric model of the Universe. Pseudo-Aristotle d. The Universe then is a system made up of heaven and earth and the elements which are contained in them.
There are "five elements, situated in spheres in five regions, the less being in each case surrounded by the greater — namely, earth surrounded by water, water by air, air by fire, and fire by ether — make up the whole Universe. The cosmos is finite and surrounded by an infinite void. It is in a state of flux, and pulsates in size and undergoes periodic upheavals and conflagrations.

Geocentric , static, steady state, finite extent, infinite time. Spherical earth is surrounded by concentric celestial spheres. Universe exists unchanged throughout eternity. Contains a fifth element, called aether , that was added to the four classical elements. Earth rotates daily on its axis and revolves annually about the sun in a circular orbit. Sphere of fixed stars is centered about the sun. Universe orbits around a stationary Earth. Planets move in circular epicycles , each having a center that moved in a larger circular orbit called an eccentric or a deferent around a center-point near Earth.
The use of equants added another level of complexity and allowed astronomers to predict the positions of the planets. The most successful universe model of all time, using the criterion of longevity. Almagest the Great System. The Earth rotates and the planets move in elliptical orbits around either the Earth or Sun; uncertain whether the model is geocentric or heliocentric due to planetary orbits given with respect to both the Earth and Sun. Medieval philosophers — A universe that is finite in time and has a beginning is proposed by the Christian philosopher John Philoponus , who argues against the ancient Greek notion of an infinite past.
Logical arguments supporting a finite universe are developed by the early Muslim philosopher Alkindus , the Jewish philosopher Saadia Gaon , and the Muslim theologian Algazel. Multiversal cosmology. Fakhr al-Din al-Razi — There exists an infinite outer space beyond the known world, and God has the power to fill the vacuum with an infinite number of universes.
Maragha school — Various modifications to Ptolemaic model and Aristotelian universe, including rejection of equant and eccentrics at Maragheh observatory , and introduction of Tusi-couple by Al-Tusi. Nilakantha Somayaji — A universe in which the planets orbit the Sun, which orbits the Earth; similar to the later Tychonic system.
Copernican universe. Nicolaus Copernicus — First described in De revolutionibus orbium coelestium. A universe in which the planets orbit the Sun and the Sun orbits the Earth, similar to the earlier Nilakanthan model. Rejects the idea of a hierarchical universe. Earth and Sun have no special properties in comparison with the other heavenly bodies. The void between the stars is filled with aether , and matter is composed of the same four elements water, earth, fire, and air , and is atomistic, animistic and intelligent.
Kepler's discoveries, marrying mathematics and physics, provided the foundation for our present conception of the Solar system, but distant stars were still seen as objects in a thin, fixed celestial sphere. Static evolving , steady state, infinite. Every particle in the universe attracts every other particle. Matter on the large scale is uniformly distributed. Gravitationally balanced but unstable.
Cartesian Vortex universe. System of huge swirling whirlpools of aethereal or fine matter produces what we would call gravitational effects.
Gas emissions discovered from interstellar comet
But his vacuum was not empty; all space was filled with matter. Immanuel Kant , Johann Lambert , 18th century. Einstein Universe with a cosmological constant. Contains uniformly distributed matter. Uniformly curved spherical space; based on Riemann's hypersphere. Expanding flat space. Steady state.
Based on Einstein's general relativity. Space expands with constant acceleration. Scale factor increases exponentially constant inflation. William Duncan MacMillan s. New matter is created from radiation ; starlight perpetually recycled into new matter particles. Friedmann universe , spherical space. Positive curvature. Friedmann universe , hyperbolic space. Hyperbolic expanding space. Negative curvature. Said to be infinite but ambiguous.
Expands forever. Dirac large numbers hypothesis. Demands a large variation in G , which decreases with time. Gravity weakens as universe evolves. Named after but not considered by Friedmann. Universe has initial high-density state "primeval atom".
Followed by a two-stage expansion. Oscillating universe Friedmann-Einstein.
