The true speed isn't known, but scientists believe it is happening over billions and billions of years for one cycle of expand and contract to be completed.

What does the universe is expanding mean?

The distance between galaxies is increasing, pretty much in all directions. This suggests that space itself is expanding. We also now know the rate of expansion is in fact increasing.


Is the universe infinitely expanding or does it expand to a particular limit?

This question has been giving nightmares to cosmologists for years.But with the current evidences, scientists have determined that the universe is expanding at an ever-increasing rate and it will expand forever.


Is the universe curve and for ever expanding?

The shape of the Universe is yet being investigated - it is not known for sure what its shape on a large scale is.As for the expansion, our current knowledge is that the Universe is not only expanding, but that the rate of expansion is increasing (it is expanding faster than in the past). It may be reasonable to assume that this trend will continue in the future, but it would also be a little premature to be completely sure.The shape of the Universe is yet being investigated - it is not known for sure what its shape on a large scale is.As for the expansion, our current knowledge is that the Universe is not only expanding, but that the rate of expansion is increasing (it is expanding faster than in the past).

What happens to the marginal product when the total product is increasing but at a decreasing rate?

When the total product is increasing but at a decreasing rate, the marginal product will also decrease.


Will there be an end to the universe just as it started with the Big Bang?

The end of the Universe will probably be quite different than the beginning. The Universe is expanding, and it seems obvious that the rate of expansion is increasing - it is expanding faster and faster. Therefore, it won't again contract into a tiny space, as was once believed.


Is the universe revolving around itself or expanding?

It is expanding, and at an ever increasing rate according to current understanding. Whether or not it is revolving is problematic, since there is no background object against which any revolution can be observed.


What is ramp voltage?

Ramp voltage is a voltage that can be steadily increasing or decreasing.


Is the world population increasing or decreasing?

its decreasing. women are having less babies every year and its fertiltiy rate is only 1.9


How far does the known universe expand in light years before it expands no more?

Who told you that it will stop expanding ? This question has been the subject of intense research, discussion, and debate among physicists and cosmologists for at least the past fifty years ... whether the expansion rate of the universe is increasing or decreasing, and whether it will continue forever or reverse and become a contraction. I think it's pretty well established by now that the rate is increasing, and that the expansion will never stop or reverse.


Does the rate of change have to be negative?

no... the sign indicates whether the rate of change is increasing or decreasing. It is only negative if the rate is decreasing over time.


What does red shift of the universe show is us?

universe is expanding at an accelerated rate.


If the hubble constant H is larger at great distances then what is happening?

An increasing Hubble constant at great distances indicates an accelerated expansion of the universe. This phenomenon is attributed to dark energy, a mysterious force causing the universe to expand at an increasing rate. It suggests that as the universe expands, the distance between galaxies grows larger, leading to a greater Hubble constant at greater distances.
