Universe Expanding facts

While investigating facts about Universe Expanding Faster and Universe Expanding Faster Than Light, I found out little known, but curios details like:

In the now-defunct Star Wars Expanded Universe, Chewbacca owes a life-debt to Han Solo because Han refused an order from the Imperial Navy to skin the Wookiee as punishment for commandeering a ship full of slaves. Han is dishonorably discharged for his insubordination.

how fast is the universe expanding?

The Star Wars expanded universe featured an elaborate backstory for Han Solo's pants

What universe expanding into?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering if the universe is expanding what is it expanding into. Here are 50 of the best facts about Universe Expanding Faster Than Expected and Universe Expanding Speed I managed to collect.

scientists think that the universe is expanding at an accelerating rate. why?

  1. Scientists believed that during the Inflationary Epoch, roughly 10^-36 seconds after the Big Bang, the universe expanded by a factor of at least 10^26 — 100,000,000,000,000,000,000,000,000, becoming the size of a grapefruit.

  2. In 1999, Douglas Adams founded h2g2.com, The Hitchhiker's Guide the Galaxy: Earth Edition, a "constantly expanding, user-generated guide to life, the universe and everything," two years before Wikipedia launched.

  3. Our galaxy plus a few more are trapped in this thing called the local group that only makes up 0.00000000001 percent of the observable universe and because of the nature of the expanding universe, we'll never be able to leave the local group. Even with light speed travel.

  4. The Fermi paradox, a concept that states that the apparent lack of life in the universe is proof that intelligent life always destroys itself before it can expand into space

  5. There is no center of the universe. The Big Bang wasn't an explosion *in* space but rather an explosion *of* space, with nothing before it. Therefore there is no center. Everything from every point is expanding, but not from a central location.

  6. The Thrawn trilogy by Timothy Zahn, which is credited with helping to revitalize the Star Wars franchise in 1991 with the release of the first novel in the trilogy, Heir to the Empire, and formalizing the Star Wars Expanded Universe

  7. The Milky Way has two expanding bubbles attached to its core that are entirely powered by gamma rays. These objects, literally “burped out” by the galaxy and known as "Fermi bubbles," are some of the weirdest objects in the universe

  8. George’s Lemaître, a Belgian Roman Catholic priest, physicist and astronomer is credited with the first formulation of an expanding universe idea, what was to become the Big Bang theory.

  9. When physicists say the "universe is expanding" they do not mean the galaxies are moving away from each other, but that the actual space in between the galaxies is expanding and pushing them away from each other.

  10. One possible ultimate fate of the universe is that since it's expanding at an accelerating pace, zero matter density will be reached, causing all matter to ionize and disintegrate. Other possible fates include the Big Rip, Big Bounce, Big Freeze, Big Crunch, and proton decay.

At what rate is the universe expanding?

Why does the universe keep expanding?

You can easily fact check why is our universe expanding by examining the linked well-known sources.

The Sagan Planet Walk - a 1.2km, 1:5bn scale representation of the solar system in Ithaca, NY - was expanded in 1997 to include Alpha Centauri (the closest neighboring star). It is located at the Imiloa Astronomy Center at the University of Hawaii, making it the world's largest exhibition.

He created the "big bang" theory of an expanding universe and wrote that the early universe was dominated by radiation not physical matter.

There is a story in the expanded universe of Star Wars which involves Han Solo and Chewbacca landing on Earth and eventually being discovered by Indiana Jones, who has been looking for Chewbacca under the falsley named 'Sasquatch' - source

The Hubble Limit represents the furthest observable objects in the universe as anything beyond it is accelerating away faster than the light it emits. Since the universe is expanding we could forever lose sight of the furthest objects.

Hubble's expanding universe theory changed the scientific view of the cosmos forever.

When will the universe stop expanding?

Edgar Allan Poe predicted the Big Bang Theory, the expanding universe and black holes a 100 years before they were propounded

How do we know the universe is expanding?

The Big Bang theory tells us that the universe began as a small, hot ball that cooled as it expanded.

The Shapley Supercluster is so big that not only does it pull itself together instead of expand with the rest of the universe, but also pulls the Great Attractor towards it.

Because the universe is cooling as it expands, scientists believe that it will end in a Big Freeze.

Eventually, the universe will become mostly invisible because space is “expanding faster than the speed of light,” for lack of better words, except for a few very nearby galaxies because of gravity. In other words, we will lose our ability to see most stars.

The idea for an expanding universe and the Big Bang came from a catholic priest from Belgium and not Hubble

When we say the universe is expanding we mean that?

Edwin Hubble, before discovering other galaxies and determining that our universe was expanding, was a two-time national champion in basketball at the University of Chicago. In fact, NASA sent one of his basketballs into space.

The Big Crunch, a theory in which the universe will ultimately stop expanding, and begin to contract on itself, resulting in either a huge black hole or a new Big Bang.

Universe is expanding faster than light so, even if we do make a spaceship which can travel at the speed of light, we will NEVER, EVER be able to get to that part of the universe. They are gone, forever.

Georges Lemaître, the Belgian Priest/Theoretical Physicist who was the original proponent of the expanding universe, the Big Bang and the first person to derive "Hubble's Law

Hubble's discovery that the universe was expanding showed that Einstein was right in the first place. Years earlier, Einstein had corrected his equations which had originally predicted an expanding universe. Einstein called the original change of his equations "the greatest blunder of my life.".

How do scientists know that the universe is expanding?

Einstein did not believe in black holes and created the cosmological constant to contrast the idea of an expanding universe because he thought it was static

To have a chance of grasping the size of the theorised 'string' in string theory, you'd have to imagine that if an atom was expanded to the size of the observable universe, the string would be the size of a tree. (analogy taken from 'through the wormhole)

Redshift is the stretching of wavelengths due to the expansion of the universe, it is called redshift because red on the visible light spectrum has longer wave lengths then others colors so over time as the universe expands the colors will change from a smaller to a larger wavelength.

Aldous Huxley, author of Brave New World, believed psychedelics were essential to expanding one’s understanding of the universe. "Each person is at each moment capable of remembering all that has ever happened to him and of perceiving everything that is happening everywhere in the universe.”

DeVry University was established in 1931, by inventor and training film producer Herman A. DeVry, to teach projector and radio repair, and later expanded to include other electronic equipment such as televisions.

There are distant stars whose light will never reach us because the expansion of the universe expands with the space-time continuum, faster than the light from those stars will be able to travel. Without violating any laws of physics.

A Planck length is SMALL Imagine the smallest particle you could see with the naked eye (about 0.1mm across) expand to the size of the observable universe. At this scale, a Planck length... would be roughly the size of a particle 0.1mm across.

Universe is not expanding(into something) but stretching!

The Universe will cool as it expands, eventually becoming too cold to sustain life. For this reason, this future scenario is popularly called the Big Freeze.

"Vacuum Decay": a terrifying universe-death scenario in which quantum fluctuations could cause our metastable, 'false vacuum' world to revert to a state of 'true vacuum' in a bubble of oblivion that expands outwards at the speed of light. It could happen at any time for no reason.

Cosmic inflation is a theory of exponential expansion of space in the early universe. It mean that the universe expands relatively gradually throughout its history

About vacuum decay, a doomsday theory in which a death bubble expanding at the speed of light might erase the universe with absolutely no warning.

About the Big Crunch. Some scientists think that the universe will eventually stop expanding and start contacting due to gravity. Eventually all matter will be compressed to a singularity and it is theorized that a second big bang will then occur, creating the universe anew.

The Universe is still expanding faster than the speed of light, long after the Big Bang

We know the age of the universe from the rate stars are expanding. If we were to rewind the universe, the starting credits would be the big bang.

This is our collection of basic interesting facts about Universe Expanding. The fact lists are intended for research in school, for college students or just to feed your brain with new realities. Possible use cases are in quizzes, differences, riddles, homework facts legend, cover facts, and many more. Whatever your case, learn the truth of the matter why is Universe Expanding so important!
