FAQ

Those who are looking for an answer to the question «Will the universe keep expanding?» often ask the following questions:

❔ Will the universe keep expanding forever?

The equations of general relativity then shows that this particular combination leads to an accelerated expansion of the universe, as given by the red line. So in …

❔ For how long will the universe keep expanding?

Says Linder, “Because dark energy makes up about 70 percent of the content of the universe, it dominates over the matter content. That means dark energy will govern expansion and, ultimately ...

❔ How do we know if the universe will keep expanding forever?

If the gravity from matter was insufficient to completely stop the expansion, the universe would continue floating apart forever. “From the announcements in 1998 and …

In an expanding universe with decreasing density and non-zero cosmological constant, matter density would reach zero, resulting in most matter except black dwarfs, neutron stars, black holes, and planets ionizing and dissipating at thermal equilibrium. Future with proton decay. The following timeline assumes that protons do decay.

Says Linder, “Because dark energy makes up about 70 percent of the content of the universe, it dominates over the matter content. That means dark energy will govern expansion and, ultimately ...

For instance, if the shape of the Universe was ‘closed’, then at some point the expansion would eventually be triumphed by contraction, causing the Universe to gradually collapse into itself. On the other hand, if it was ‘open’, the Universe would keep expanding forever.

Until recently, cosmologists (the scientists who study the universe) assumed that the rate of the universe’s expansion was slowing because of the effects of gravity. However, current research indicates that the universe may expand to eternity.

The equations of general relativity then shows that this particular combination leads to an accelerated expansion of the universe, as given by the red line. So in conclusion, yes, we think the universe will expand forever, and at an ever increasing rate! Russell Swan. , A lover and follower of the physical sciences.

Even though we don’t actually know what dark energy is, we can now answer the original question — yes, the universe will expand forever and we’ll experience a “big freeze”, not a “big ...

The universe is everything, so it isn't expanding into anything. It's just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there's no center they're expanding from and no outer edge to expand into anything else.

if the Universe is infinite then it can’t technically expand but you could make the case that matter or objects could keep expanding in it.. much of the trouble in Physics is due to a lack of properly defined terms.. basic things like mass, energy, space, waves, etc. have definitions that are either inexact or differ depending on the source.. in my way of looking at it, any edge to a Universe makes no sense and space exists whether there is matter or photons or anything in it.. so the ...

Also that our universe and all of space had a beginning, We are expanding and moving as all energy has the potential to push and pull depending on its strength of charge, gravity ,electrons ...

Why is the universe expanding?

The tiny differences in temperature, and thus density, help cosmologists determine the shape of the Universe. For instance, if the shape of the Universe was ‘closed’, then at some point the expansion would eventually be triumphed by contraction, causing the Universe to gradually collapse into itself.

How quickly is the universe expanding?

The farther away a galaxy, the faster it will go away from us. Check the Wikipedia article on "Hubble's Law" for more details. According to the article, the currently accepted value for the "Hubble constant" is 74.2 ± 3.6 (km/s)/Mpc. That is to say, if a galaxy is at a distance of 1 Megaparsec, on average our distance from this galaxy will increase at a rate of about 74 km/s. For a galaxy at 2 Megaparsec distance, the speed would increase at twice this value, etc.

Is the universe expanding or contracting ?
