Before Newton’s law of gravity, there were many theories explaining gravity. Philoshophers made observations about things falling down − and developed theories why they do – as early as Aristotle who thought that rocks fall to the ground because seeking the ground was an essential part of their nature.

Theory of Everything, freeview video by the Vega Science Trust, BBC and Open University. The Theory of Everything : Are we getting closer, or is a final theory of matter and the universe impossible? Debate between John Ellis (physicist) , Frank Close and Nicholas Maxwell .
Such comparatively simple universes can be described by simple solutions of Einstein's equations. The current cosmological models of the universe are obtained by combining these simple solutions to general relativity with theories describing the properties of the universe's matter content, namely thermodynamics, nuclear-and particle physics.
The Universe is an American documentary television series that features computer-generated imagery and computer graphics of astronomical objects in the universe plus interviews with experts who study in the fields of cosmology, astronomy, and astrophysics. The program was produced by Flight 33 Productions and Workaholic Productions.
The matter must, of course, also satisfy whatever additional equations were imposed on its properties. In short, such a solution is a model universe that satisfies the laws of general relativity, and possibly additional laws governing whatever matter might be present. [53]
Dark matter is a hypothetical kind of matter that is invisible to the entire electromagnetic spectrum, but which accounts for most of the matter in the universe. The existence and properties of dark matter are inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe.
In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction primarily observed as mutual attraction between all things that have mass.Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 29 times weaker than the weak interaction.
Antimatter – Material composed of antiparticles of the corresponding particles of ordinary matter; Dark energy – Energy driving the accelerated expansion of the universe; Dark matter – Concept in cosmology; Gravitational interaction of antimatter – Theory of gravity on antimatter; Mirror matter – Hypothetical counterpart to ordinary ...
