Expansion of the universe - Wikipedia
A graphical representation of the expansion of the universe from the Big Bang to the present day, with the inflationary epoch represented as the dramatic expansion seen on the left. This visualization shows only a section of the universe; the empty space outside the diagram should not be taken to represent empty space outside the universe ...
WMAP- Expansion of the Universe - NASA
2024年2月22日 · Today, Cepheid variables remain one of the best methods for measuring distances to galaxies and are vital to determining the expansion rate (the Hubble constant) and age of the universe. What are Cepheid Variables? The structure of all stars, including the Sun and Cepheid variable stars, is determined by the opacity of matter in the star.
WMAP Expansion of the Universe - NASA
2010年4月16日 · The top (red) curve shows a universe in which a large fraction of the matter is in a form dubbed "dark energy" which is causing the expansion of the universe to speed up (accelerate). There is growing evidence that our universe is following the red curve.
Accelerating expansion of the universe - Wikipedia
Lambda-CDM, accelerated expansion of the universe. The timeline in this schematic diagram extends from the Big Bang /inflation era 13.8 billion years ago to the present cosmological time.
Model of expanding Universe | ESA/Hubble
2001年4月2日 · Model of expanding Universe This diagram reveals changes in the rate of expansion since the Universe's birth 15 billion years ago. The more shallow the curve, the faster the expansion.
The Expansion of the Universe - WorldWide Telescope
Hubble’s Law shows our Universe to be ever-changing, expanding its limits in space and time simultaneously. In 1929, the American Astronomer Edwin Hubble made a simple graph showing that galaxies farther from each other move away from each other systematically faster.
11.6 The Big Bang - University Physics Volume 3 - OpenStax
Explain the expansion of the universe in terms of a Hubble graph and cosmological redshift; Describe the analogy between cosmological expansion and an expanding balloon; Use Hubble’s law to make predictions about the measured speed of distant galaxies
Imagine the Universe!
2020年9月24日 · Hubble's graph of redshift versus distance. One way to think about the expanding Universe is to imagine that the Universe is a loaf of raisin bread. The galaxies are the raisins, and the dough is the space between galaxies or large structures.
Webb, Hubble Telescopes Affirm Universe's Expansion Rate
2024年6月13日 · The best measurements from Hubble show the universe is now expanding faster than predicted based on observations of how it looked shortly after the big bang. These observations were made by the Planck satellite mapping of the cosmic microwave background radiation – sort of a blueprint for how the universe would evolve structure after it ...

2024年12月21日 · Some 13.8bn years ago, the universe came into existence in the Big Bang. Its first moments were a period of pure energy with intense, possibly infinite, heat and density. As the universe expanded ...
