They're both theoretical constructs and neither has actually been detected, measured, nor "seen".

Is the universe matter?
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.
What is the opposite of Dark Energy?
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.
Why is a block of ice which when heated converts into liquid and then into gas considered as matter?
Because they are all matter. The three most common states of matter that we are familiar with here on earth take the form of sold (ice), liquid (water), and gas (vapor). T he most common form of matter is a fourth kind called plasma. It is mostly found in stars and makes up roughly 99.9% of all matter in the universe, not including dark matter and dark energy.
How are dark matter and dark energy similar?
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.
Were is most of the dark matter in the milky way universe?
I dont know correctly but it may be most of the galaxy I think so! In reality we don't 'know' but our best understanding is; Ordinary matter: ~4.5 %, dark matter: 23%, dark energy: 72%. Reputedly 80% of this 23% dark matter is cold dark matter and 20% is hot dark matter. It has been said that "dark matter.... makes up more than 80% of the matter of the universe." but that is a common misunderstanding; But we MAY say; up to 96% of the mass-energy in the universe is 'dark'. We don't know what dark matter is, but in fact it only means it does not have an easily detectable 'electromagnetic cross section' so it could be electrons/ions plasma, which has a refractive index of 1.
What is the state of most of the matter is the universe?
The most common type of energy/mass in the Universe is in the form of dark energy, followed by dark matter. Only about 4% of the Universe is in the form of "normal" (baryonic) matter. If it is specifically to this matter you refer: the most common state of matter is plasma, found in stars.

Which is thought to be more prevalent in the universe dark matter or dark energy?
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
Can Astronomer's directly detect dark energy and dark 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.
Why dark energy and matter does not obey standard physics and chemistry?
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.
Compare the amount of visible matter in the universe with the total amount of matter and energy?
4% Visible Matter (Atoms) 23% Dark Matter 73% Dark Energy
What is dark energy matter?
haga
What is space that has no matter?
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.
What is the most common form of matter?
Dark energy is believed to make up about 73% of the mass of the Universe; dar matter about 23%; and normal matter - the kind we know most about - about 4%. In the case of normal matter, most of it is still in the form of hydrogen.
Do scientist think that dark matter and dark energy exist?
Yes, they do.
What is a negative space?
Negative space is dark energy and dark matter.
What form of energy does earth not have?
Dark Matter
