No, at present dark matter can't be used as energy.
However, when Marco Polo went to China he observed the them burning black rocks (coal) for heat. This was an unknown and unexpected source of energy in Europe at the time. Undiscovered sources of energy are by definition presently unknown.
Yes, it appears so. Frank Zwicky first proposed dark matter back in the 1920s, after he noted galactic spin rates appeared to be higher than the visible matter could account for. His proposal was met with skepticism (and rightly so), but in more recent years we have begun to find more compelling reasons to think he was right. The evidence accumulates for there being something unseen there.
Two competing theories for dark matter are MACHOs (Massive Compact Halo Objects) and WIMPS (Weakly Interacting Magnetic Particles). We will be building equipment to test which of these is most likely right fairly soon, and to give us better insight on just what dark matter is. If it is something cool we can use, wouldn't that be groovy?
The concepts of dark matter and dark energy are too ill-defined to suggest an answer to your question, but probably not. Dark matter and dark energy are "somethings" we surmise to answer a set anomalies raised by observed conditions. There is no observed anomaly that requires dark light to put things back in their proper order, and the term is a bit self-contradictory.
"Dark matter" interacts with baryonic matter -- ie, the stuff we understand -- via gravity but not in any other significant way. Not via the electromagnetic force, nor via the strong force, possibly not even via the weak force. What this stuff happens to be is still being debated.
Dark matter, however, can NOT be simply energy in our cosmos. If it were, it would push space apart -- which is what dark energy is doing. Dark matter, on the other hand, is doing the exact opposite -- it is pulling space (and the matter within it) into it. Thus, dark matter is SOME kind of matter (or mass, which is the same thing) which, at present, we don't fully understand yet.
Mainly in that both are mysterious - not much is known about them. You are right but these two are not similar. Actually they are opposite to each other. dark matter pull the body closer while dark matter push them away.
Dark matter can't be doing both pulling and pushing as your answer suggested. So there is a mistake in the sentence. What is that.
Sorry for my mistake and thanx for suggestion please read second dark matter as dark energy. Infect dark energy push the objects like planet away
Dark matter and Dark energy are mysterious concepts aimed at covering defects in the current theoretical framework. Dark matter covers the" missing matter" that holds galaxies together at the observed speeds of observation.
Dark energy covers the "missing energy" that supports the idea of expansion of the universe.
A better theory will do away with Dark matter and Dark energy. Dark matter is the result of theorizing that gravity is the dominating force in galaxy motion, rather than electromagnetism. Dark energy is the result of theorizing that the universe is expanding based on "redshift" data.
Dark matter and Dark energy will be de-mystified with Quaternion Physics.
Quaternion Physics is four dimensional with scalar energy and vector energy.
Dark energy is Ev=cP=cmV. This energy creates the centrifugal force and the redshift, that balances gravitational contraction,, not expansion. Redshift indicates this balance. The larger the redshift the greater the gravitational attraction. The "hitherto unrecognized principle of nature " is Continuity.
Dark matter is the electromagnetic force created by charged bodies moving in an magnetic field. Again the energy is cP=cmV. The moving charged bodies are accelerated by electro-magnetic fields, not gravity. See Hannes Alfven.
In physical cosmology and astronomy, dark energy is a hypothetical form of energy that permeates all of space and tends to accelerate the expansion of the universe. Dark energy is the most accepted hypothesis to explain observations since the 1990s that indicate that the universe is expanding at an accelerating rate. In the standard model of cosmology, dark energy currently accounts for 73% of the total mass-energy of the universe.
In astronomy and cosmology, dark matter is a type of matter hypothesized to account for a large part of the total mass in the universe. Dark matter cannot be seen directly with telescopes; evidently it neither emits nor absorbs light or other electromagnetic radiation at any significant level. Instead, its existence and properties are inferred from its gravitational effects on visible matter, radiation, and the large scale structure of the universe. Dark matter is estimated to constitute 84% of the matter in the universe and 23% of the mass-energy.
Perhaps. We know nothing about "dark matter"; not even if it actually exists, or is just a fanciful thought of a scientists who couldn't think of any other way to come up with enough mass to keep the galaxy together.
The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.
There is no opposite of dark energy in the sense that there exists something that is the exact opposite of dark energy. Dark energy speeds the rate of expansion of space, even empty space, and gravity, mass, or matter causes the opposite in that it causes a decrease in the rate of expansion of space in areas that have matter.
The only similarity we know of is that they all seem to interact with gravity. Aside from that, scientists do not know what dark matter is.
Dark matter is a different type of matter not like we have on Earth; we can prove matter is here on Earth it's called baryonic matter. Dark matter is different it does not emit or reflect electromagnetic radiation which makes it harder for astronomers to find it. Dark matter is observed by the gravitational effect that it has on radiation and the visible universe. The gravitational force it has from dark matter plays a critical role in the shape of the galaxies orbit and the because of the hot gases in the groups of galaxies. Dark matter also has an effect on visible light caused by the groups of galaxies that is more known as gravitational lensing. This unknown matter is called dark matter, because we do not know what these undiscovered matter particles are. In time we will know and discover these particles and will soon be properly understood. Dark matter and dark energy are different but do have some of the same features. Dark energy is different from dark matter because dark energy is making more room in the galaxies which is making more room; so now since there is so much more room because of the dark energy it is moving all the galaxies around us drift away from us. Astronomers thought that the rate of the universe expanding would soon be slowing to a stop; more recent measurements showed that the rate of the universe expanding is actually going at a faster rate of speed. The relationship between dark matter and dark energy is that both make up about 96% of the matter in the known universe. They are not the same dark energy is what is creating the expansion of the universe, and dark matter is what holds the universe's galaxies and other objects in place. Although they do share some features, dark matter or dark energy cannot be observed or measured by any of the tools or techniques that we have currently today. They both serve as place holders for basic principles of the universe. Answer2: Dark Energy an Dark Matter are the result of defining enerrgy as a scalar quantity. Dark Energy is a vector quantity. This is explained with Newton's Gravity Energy. Newton's Energy is W = -mGM/r the is a scalar energy, a potential energy. Newton's Law is as if the mass m is not moving. The mass m is moving and tthus creates momentum, a vector. it als creates cmV=cP vector energy, the so-called Dark Energy. This the total Energy is W = -mGm/r + cP = -vp + cP This is a Quaternion Energy consisting of a scalat part and a vector part, cP. This Dark Enegy cP is larger than the -vP by the ratio of c, the speed of light and v the velocity. This Dark Energy is also the source of the Dark Matter, cP. The universe consists of Quaternion quantites, at the scale of the univers and the atom. The Gravitational and Quantum Energy is W = -vh/2pi r + cP = -vp + cP = [-vp,cP] The Energy is Conserved at 0 =XW= [d/dr,Del][=vh/2pi r,cP] when v=c. indicating that the Univers is stationary due to Dark Energy. 0 = [vp/r -cp/r, -1R cp/r + 1R vp/r].
I think the question is a bit mixed up, but I think this is the answer. Scientists talk about "mass-energy" as a unified thing. Just after the Big Bang "energy", in the form of radiation energy, was dominant. However, today it seems that "mass" is the dominant form. In other words, "matter" now dominates the Universe. There is the complication of "Dark Matter" and "Dark Energy". Cosmologists still don't really know what these are. So that puts some uncertainty into this discussion of matter and energy. Some scientists believe that it is now "energy" that dominates, because of the discovery of Dark Energy. (Also, cosmologists think that both "matter" and "anti-matter" were created, but that there was a slight imbalance in favour of matter and the anti-matter seems to have been destroyed, leaving just "matter".)

Dark energy. The current estimates for the distribution of mass/energy in the Universe are approximately: 68% dark energy 27% dark matter 5% baryonic (i.e. "normal") matter
Dark matter and dark energy have NOT been detected yet, so any ideas about detecting dark energy and dark matter, whether it be directly or indirectly, is speculation for now.
Standard physics and chemistry are based on the energy and matter that we know. We do not know much about dark energy or dark matter, but only that it may exist.
4% Visible Matter (Atoms) 23% Dark Matter 73% Dark Energy

Space that has no matter is called a vacuum. It is characterized by the absence of particles, such as gas molecules and atoms, and is devoid of any substance. Vacuums exist in outer space and are created artificially in vacuum chambers on Earth.
Yes, they do.
Negative space is dark energy and dark matter.
Dark Matter
It is believed that about 4% of the mass in the Universe is normal matter. About 23% is dark matter (matter of unknown composition), the remainder being something even more mysterious called dark energy. I suggest searching the Wikipedia for "dark matter" and "dark energy", for more details about both.
Yes. Dark energy is responsible for the expansion of the universe.
