The time-lapse of the entire universe is pretty interesting. "How did it begin" is an interesting question. "How vast is our universe" is also puzzling. The Story of our Great Universe is here in 1 minute. The visuals are pretty exciting.
See the extreme Timelapse of the evolution of Universe. The video compressed the Entire Timeline Of universe (13.8 B Years ) in a Minute scale. From the Big-Bang to Present. Primordial clouds to Our Sun. Supernova Explosion and formation of the Black-hole. Collision to exciting Formation. And the Rise of life. The visual images put together are pretty exciting in : Time-Lapse of the Entire Universe. This video is: Extream Animation, VFX, SFX. Use Headphones for a really better Experience.
How did the universe start? There are theories out there. The Big Bang theory is a cosmological model of the observable universe from the so-called earliest known periods through its subsequent large-scale evolution. The model describes how the universe expanded from an initial state of high density and temperature, and offers a comprehensive interesting deep explanation for a broad range of observed phenomena, including the abundance of light elements, the cosmic microwave background (CMB) radiation, and large-scale structure.
Crucially, the theory is compatible with Hubble-Lemaître law - the certain observation that the farther away galaxies are, the faster they are moving away from Earth. Extrapolating this cosmic expansion backwards in time using the known laws of physics, the theory describes a high density state preceded by a singularity in which space and time lose meaning. There is certainly no evidence of any phenomena prior to the singularity. Detailed measurements of the so-called expansion rate of the universe place the Big Bang at around 13.8 billion years ago, which is thus considered the age of the universe.
Expansion of space is pretty interesting.
ReplyDeleteThe expansion of the Universe was inferred from early 20th century astronomical observations and is an essential ingredient of the Big Bang theory. Mathematically, general relativity describes spacetime by a metric, which determines the distances that separate nearby points. The certain points, which can be galaxies, stars, or other objects, are specified using a coordinate chart or "grid" that is laid down over all spacetime out there.
The cosmological principle implies that the metric should be homogeneous and isotropic on large scales.
This metric contains a scale factor, which describes how the size of the universe changes with time. This enables a convenient choice of a coordinate system to be made, called comoving coordinates. In this coordinate system, the grid expands along with the universe, and objects that are moving only because of the expansion of the universe, remain at fixed points on the grid. While their coordinate distance (comoving distance) remains constant, the physical distance between 2 certain such co-moving points expands proportionally with the scale factor of the co-called universe.
Astronauts onboard the International Space Station spend most of their time doing science, exercising and maintaining the station. They can play sports in outer space, such as: Baseball, Chess, Soccer, Gymnastics, Basketball, Golf, Football and more.
