Why is the universe expanding.
The straight answer is that the universe doesn't expand into anything. There is no space "out there" for it to expand into. What the cosmic expansion does is stretch …
There’s a lot of chatter around what kind of stimulus is needed to save the economy and ensure financially vulnerable Americans can retain some degree of stability. Talks have incl...The universe is not expanding into anything. Alternatively, you could say that it's expanding into itself. There is no "end" to the universe, it is infinite in all directions. Here's an analogy I like to use: Say we have a two-dimensional universe, it's an infinite flat plane. It has a 1x1 inch grid inscribed on it, like graph paper.The universe does not expand into anything because, as far as any evidence we have goes, it is everything that exists. In other words, there is nothing outside of the universe. We often think of ...The cause of this continuing expansion is said to be Dark Energy. The Expanding Universe entails expansion of space not energy and matter, this is a warped definition of the the Universe as only ...
One intriguing reason could be that dark energy – the mysterious force that seems to be driving acceleration of the expansion of the universe – is itself not uniform. In other words, the X-rays may reveal that dark energy is stronger in some parts of the universe than others, causing different expansion rates.Webb measurements shed new light on a decade-long mystery.The rate at which the Universe is expanding, known as the Hubble constant, is one of the fundamental parameters for …

The puzzle, called the "Hubble Tension," is that the current rate of the expansion of the universe is faster than what astronomers expect it to be, based on the universe's initial conditions and our present understanding of the universe’s evolution. Scientists using NASA's Hubble Space Telescope and many other telescopes …
That model of breakneck expansion, called inflation, may explain why the universe has such an even temperature and distribution of matter. After inflation, the universe continued to expand but at ...
Oct 28, 2016 · One of the criticisms the new paper levels at standard cosmology is that the conclusion that the Universe is accelerating is model dependent. That's fair enough. Usually cosmologists are careful to say that we are studying 'dark energy', which is the name we give to whatever is causing the apparent acceleration of the expansion of the Universe.

Oct 24, 2017 ... In a Nutshell : The universe is expanding because it is filled with more dark energy than matter. At the Start … According to the big bang ...The expansion rate of the Universe, as we measure it (even with our current ongoing controversies ), is somewhere around 70 km/s/Mpc, which means that for every Megaparsec away a “raisin” is ...The Universe May Not Be Expanding. A theoretical physicist has published a paper arguing the universe may be static, but the mass of everything is growing exponentially. How do we know the ...Expanding Universe. The distant galaxies we see in all directions are moving away from the Earth, as evidenced by their red shifts. Hubble's law describes this expansion. The fact that we see other galaxies moving away from us does not imply that we are the center of the universe! All galaxies will see other galaxies moving away from them in an ...
If so, why? — Bill Ellena. It’s true — not everything is expanding. The earth is not expanding. The distance between the earth and the sun is not expanding. And in fact, the distance between ...The universe is expanding faster than predicted by popular models in cosmology. NASA The Hubble tension. Over the past few years, I’ve been researching ways to explain this Hubble tension. The ...The physical universe is defined as all of space and time (collectively referred to as spacetime) and their contents.

The universe also …The ESA (European Space Agency) Euclid spacecraft lifted off from Cape Canaveral Space Force Station in Florida at 11:12 a.m. EDT on Saturday, July 1, beginning its mission to study why the universe is expanding at an accelerating rate. Astronomers use the term “ dark energy ” in reference to the unknown cause of this accelerated …Discovering the Runaway Universe. Our cosmos is growing, and that expansion rate is accelerating. Astronomer Edwin Hubble first measured the expansion rate of the universe in 1929. Using the 100-inch Hooker Telescope on Mount Wilson in California, Hubble discovered that the farther a galaxy is from us, the faster it appears to be receding into ... By precisely determining the expansion rate, called the Hubble constant, the cosmic clock can be rewound and the age of the universe calculated. However, Edwin Hubble's estimates of the expansion implied that the universe was younger than the age of the Earth and the Sun. Hubble, therefore, concluded that the redshift phenomenon was an unknown ... The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. The Big Bang theory was inspired by the discovery of the expanding Universe by Edwin Hubble. It was first proposed in 1927 by Roman Catholic priest and physicist Georges Lemaître.Lemaître …
In fact, the amount by which the Universe has expanded is given by the term 1 + z. For example, for an object with a redshift of z = 1, the Universe has expanded by a factor of 2 since the time the light left that object. For z = 0.5, the Universe has expanded by a factor of 1.5, or 50%. The expansion of the Universe is know, but how much do we know about this process? Answers to questions about the expansion of the Universe. ...
AS DOUGLAS ADAMS once wrote: “The universe is big. Really big.” And yet if our theory of the big bang is right, the universe was once a lot smaller. Indeed, at one point it was non-existent.It is the distance in non-expanding space that an object should be at to have the same angular size that an object in an expanding universe actually has at that redshift.

Therefore if the Universe is not expanding, the redshift of light with increasing distance must be caused by some other phenomena – something that happens to the light itself as it travels through space. “We are not speculating now as to what could cause the redshift of light,” Mr Lerner said. ”However, such a redshift, which is not ...This method predicts that the universe should be expanding at a rate of about 67.36 kilometres per second per megaparsec (a megaparsec equals 3.26 million light-years). By contrast, other teams measure the Hubble constant by looking at the “local” universe: the more modern stars and galaxies that are relatively close to us.
