What is the mysterious force that may be causing the expansion of the universe?

Sorry to tell you this, but it's MYSTERIOUS!
Hey, what can I say? There is a LOT that we don't know about how the universe works, and every time we find one answer, it seems to bring up three new questions!
I can guarantee you this; half or more of what we think we know right now about physics, and the way the universe works, is flat-out wrong. The problem is, we don't know which half!
One hundred years ago, we had no idea of what force kept the Sun going.
Today, we think we know a lot about the Sun, but we don't know why sunspots happen, or what the sunspot cycle is 11 years (except sometimes it isn't!) or why some of the biggest stars seem to be bigger than our math would allow them to be. We don't know what the minimum size of a star is, either, or why stars form. 25 years ago, most astronomers agreed that planetary systems were certainly rare; now it seems that every star we examine has planets.
As Tommy Lee Jones says in the movie "Men In Black"; "Just imagine what you'll know tomorrow!"

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 force do scientists such as Saul Perlmutter believe is counteracting gravity and allowing the universe to accelerate the rate of its expansion?
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.
How much of the universe is matter?
The real question is how much of the universe's matter is this dick.
Dark energy is an unexplained force that is causing?
Dark Energy is an unexplained theoritical mathematical quantity that is proposed to account for the apparent steady increase in the rate of expansion of the universe.
Why is the Universe expanding every moment?
Seems to be a residue of the "big bang". I think the reasons for this are not yet entirely clear. Specifically, there is some mysterious force that makes our Universe expand faster and faster! The reason is called "dark energy", but what it really is, is actually a mystery.The initial expansion of the Universe is attributed to "inflation", attributed in turn to a particle called an "inflaton". The details are also as yet unknown.Seems to be a residue of the "big bang". I think the reasons for this are not yet entirely clear.

What does dark energy seem to be doing?
Dark energy is the force that is driving the expansion of the universe
What will cause the rate of expansion of the universe to slow down?
The expansion rate of the universe is determined by the mass of the things in the universe and the strength of the gravitational force. The universe would start to slow down if some new form of matter were to intervene which incresed the over all mass of the universe, or if there's some property of gravity that we don't know of, where at some threshold it actually becomes stronger.
Could gravity mimic galatic expansion?
Gravity is an attractive force wich pulls everything together, however, the universe is being pulled apart and therefore graviy is not what is doing this. The force which is pulling the universe apart is dark energy wich is a repulsive force which pulls everything apart.
Do you have any thing like anti gravitational force in the universe?
There is a force called as gravitational force in the universe. The most beloved scientist, Newton has derived the law of gravity. But it has never been explained that as to why there is force of attraction and not the force of repulsion. When there is the force of attraction, there has to be the corresponding force of repulsion in the nature. You can not have the isolated north pole, with out the presence of south pole. So you have the force of attraction between matter to matter. You have force of attraction between anti-matter to anti-matter. So there has to be force of repulsion between matter to anti-matter. So the matter will repel the anti-matter in the space. So you have lost the universe (universes) in the space. The presence of matter is the proof that the anti-matter exists in the space in exactly equal amount. This is subjected to the inter conversion of matter into energy as per the law of Einstein, that is E = m c 2. The law of gravity is stated as F = G m 1* m 2 / r 2. If one of the mass is anti-matter, then the formula is : minus F = G (minus m 1)* m 2. Here the value of F also becomes negative. So that becomes the force anti to the force of gravity. That is force of repulsion. Hence proved.
What is driving the expansion of the universe?
Although it is a hot topic of debate, some scientists postulate that the mysterious force behing the universes expansion is Dark Energy, which we don't know much about at all; hence the name (dark) is used to conceal our ignorance.
What is the difference between dark energy and dark matter?
The two are quite unrelated. It would be harder to find similarities than differences. More exactly, the two are only related by the fact that (as of 2013) we don't understand either -- thus the name "dark." Dark matter is the type of matter that exists throughout our Universe, which interacts with baryonic matter (ie, the stuff we understand) only through gravity. This stuff (whatever it happens to be) warps space and prevents galaxies from flying apart as they spin; but does not interact via the electromagnetic force, the strong force, or the weak force. Its mass density in our Universe, as best we can tell, is about six times greater than that of bayronic matter. Dark energy is whatever is causing the space within our Universe to increase the rate of expansion. Gravity SHOULD be slowing down that expansion over billions of years, but SOMETHING is causing the rate to go higher. What is causing this? -- we have no idea!!
What is the role of the dark energy in the expansion of the universe?
The universe is expanding faster than it would be, if the only source of energy for that expansion derived from the big bang. In face, recent astronomical observations have shown that the rate of expansion of the universe is increasing, which indicates that there is some force still at work, pushing on galaxies and making them move faster. We have very little idea what that source of expansion is, but we have called it "dark energy" to reflect the fact that we cannot see it (or haven't seen it so far; maybe we aren't looking in the right place).
