Yes, dark matter has a lot of mass. It makes up about 20% of the universe (much more than regular matter). Since it has mass, it also has energy.
In fact, dark matter's mass is the main reason we even know it exists. Astrophysicists can observe its gravitational effects, though it is extremely hard to detect in any other way.
What else can I help you with?
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
What accounts for most of the mass in the universe?
Current theory states that it's "dark energy".
Is it true that most of the both the mass and energy in the universe may take forms that you are unable to detect directly?
Yes, that's quite true! For more information, read sources such as Wikipedia on "dark matter" and "dark energy". Current estimates are that something around 68% of the mass-energy in the Universe is in the form of dark energy; 27% is in the form of dark matter; and about 5% matter of known types. Nobody really knows much about "dark energy" or "dark matter" - only that they exist.
What percentages of universal mass are claimed by dark energy dark matter and visible matter?
About 95.7% of the universe is dark matter, and the remaining percent (4.3%) is made of normal matter, plants, gases and such.
What percentage of the universe is 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.
What things that are not matter?
Matter is anything that has mass and volume, so there can be things like energy which are not necessarily matter.
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.
What is the energy of charged particles of matter?
The energy of charged particles of matter is determined by their kinetic energy, which is related to their velocity and mass. Additionally, charged particles can possess potential energy due to their interaction with electric and magnetic fields.
What is the estimated universal mass percentage of gravity-lensing dark matter?
Dark matter is estimated to be responsible for about 27% of the total mass-energy in the universe (normal matter is a bit under 5%)."Gravity-lensing" is essentially a meaningless phrase here; all mass causes gravitational lensing, so there's no such thing as "non-gravity-lensing" dark matter.
Can matter be created by dark energy?
matter cannot be created or destroyed, only transformed/transferred. lrn2Law of Conservation of Mass.
Does antimatter possess negative mass?
No, antimatter does not possess negative mass. Antimatter has the same mass as regular matter, but opposite charge.
What might much of the mass of the universe be composed of?
The universe is made mostly of dark matter and dark energy, and we don't know what either of them is.
