Dark energy is the term to refer to the force that is causing an expansion of the universe to accelerate. It is estimated that the universe is 68.3 percent dark energy, 26.8 percent dark matter, and 4.9 percent ordinary matter.

What is expansion of liquid?
expansion of liquids
What is the increase of the volume of a substance by the increase of temperature called?
This increase of volume is called expansion
What is water expansion?
temperaturewater's most density: 4 degrees Celsius ( = lowest expansion rate)
What is the expansion of power?
Expansion of tanθ in power of θ
Air expansion and contraction?
expansion is when the air is HOT !
When will universal expansion accelerate?
I would say no. There is no reason to expect it to accelerate.
What is a component of the universe that seems to be counteracting the effect of gravity and accelerating the expansion of the universe?
Dark energy.
The mysterious force that may be causing the expansion of the universe to accelerate is called?
The current state of affairs with regard to the expansion of the universe point to dark energy as the cause of the expansion of the universe. It is not a force though.
What are three advantages of cartel?
1.Counteracting the diminution of profits due to competitive struggle by mutual price-agreements 2.A uniform market condition for the whole trade 3. Expansion of Trade.bergds, Daison Souza
What is dark energy in the universe?
The mysterious substance which is believed to accelerate the Universe's expansion. Look up "dark energy" on Wikipedia for more details.
What describes scientists' best idea about the formation and expansion of the universe?
A person who learns about the world by observing it
What is a dark energy and is it similar as the black hole?
In physical cosmology and astronomy, dark energy is an unknown form of energy which is hypothesized to permeate all of space, tending to accelerate the expansion of the universe.
Did the Middle Ages have thermometers?
No, there were not thermometers in the middle ages. There were some ancient scientists who know about expansion and contraction with temperature, but the idea was not applied to thermometers until the Renaissance.
Does the universe keep on expanding?
Yes, and so far, scientists have not yet accounted for enough mass in the universe for the expansion to ever come to a halt and start the universe contracting.
Will the big bang ever happen again?
Scientists have largely dismissed the notion of a cyclical universe. So the short answer is: no, this universe will probably not undergo collapse and re-expansion.
What is the majority of the energy in our universe?
Something called "dark energy" which provides almost 70% of the total energy in the observable universe and is causing the expansion of the universe to accelerate (instead of decelerate as expected in the basic big bang model of the universe).
Why do scientist think the universe will expand forever?
There is actually considerable debate about that. Some scientists believe that the universe (or at least, the part we can see!) is not massive enough to cause the current expansion to slow down and reverse, and other scientists believe that "dark matter" may provide enough mass to reverse the expansion.From a philosophical viewpoint, the idea of an "oscillating" universe - big bang followed by expansion, followed by contraction, followed by collapse, and repeat forever - is more appealing. But at present, the balance of the evidence seems to be against it.There is evidence that the expansion of the Universe has been accelerating. It is not known exactly why, and it is possible that the expansion may slow down again, but this doesn't seem very likely.
