[1] [2] With the use of computer-generated imagery (CGI) and visual effects, each episode presents and narrates a topic about the universe (e.g.: the origin of the universe, the formation and the evolution of the Solar System, and the origin and behavior of life), which then are complemented with scientific insights from leading scientists of ...
In his introduction Boeke says the work originated with a school project at his Werkplaats Children's Community in Bilthoven. The idea was to draw pictures that would include ever-growing areas of space, to show how the Earth is located in an unfathomably enormous universe. Boeke then writes that he realized the reverse process—creating ...
While the local geometry does not determine the global geometry completely, it does limit the possibilities, particularly a geometry of a constant curvature. The universe is often taken to be a geodesic manifold, free of topological defects; relaxing either of these complicates the analysis considerably. A global geometry is a local geometry ...
The Hubble eXtreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed at that time. Except for the few stars in the foreground (which are bright and easily recognizable because only they have diffraction spikes), every speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is ...
The history of the universe after inflation but before a time of about 1 second is largely unknown. [22] However, the universe is known to have been dominated by ultrarelativistic Standard Model particles, conventionally called radiation, by the time of neutrino decoupling at about 1 second. [23]
The physical universe is defined as all of space and time [a] (collectively referred to as spacetime) and their contents. [10] Such contents comprise all of energy in its various forms, including electromagnetic radiation and matter, and therefore planets, moons, stars, galaxies, and the contents of intergalactic space.
The universe's size is unknown, and it may be infinite in extent. [14] Some parts of the universe are too far away for the light emitted since the Big Bang to have had enough time to reach Earth or space-based instruments, and therefore lie outside the observable universe. In the future, light from distant galaxies will have had more time to ...
