It is currently estimated that 73% of the mass in the Universe is a mysterious substance called dark energy, 23% is another mysterious substance called dark matter, and 4% is made up of "normal" matter (matter of known composition).
Answer2: the mass of the universe (2E53 kg) is normal matter including Plasma! Dark Energy" is the result of theoretical defects. Dark energy is the centrifugal vector energy mcV, associated with the the proper Quaternion Gravitational theory:
E = -mGM/r + mcV = - mu/r + mcV
The universe is composed of Quaternions, a scalar and three vector parts; a boson and a fermion part. Newton and Einstein's gravitational theories do not include the vector component mcV. Incorporating this proper quaternion energy the universe is seen to be in equilibrium and the redshift is the indicator of Continuity.
Equilibrium is
0 = (d/dr + Del)E
0 = (d/dr +Del)m(-u/r + cV) = m(u/r2 - cDel.V) + m(cdV/dr - Del u/r + cDelxV)
At Continuity, cos(RV) = v/c. At equilibrium v=c and GM/r = c2
The Quaternion universe is composed of normal matter and properly viewed has no need of "dark energy or dark matter (electric universe).

∙ 14y agoMost of the matter in our galaxy - at least 80% or so - resides in a mysterious so-called "dark matter". It is not known what this is exactly. This is one of the most pressing problems in modern Astronomy. We know that the mater exists (it shows itself through gravitational interaction), but we don't know almost anything about its nature.

∙ 14y agoA good question. Some calculations indicate that the majority of the mass in the Milky Way galaxy is unaccounted for; that is, we know that the mass exists because its gravity keeps the galaxy together. But when we add up all the stars, nebulas and gas clouds, we don't have nearly enough mass.
Some scientists believe that "dark matter" between the stars must be contributing to the Milky Way's gravity, while other scientists believe that the missing mass may be contained in a super-massive black hole at the center of the galaxy.
The only completely honest answer right now is "We don't know yet."

Does the supermassive blackhole at the center of your galaxy contain most of the mass of the galaxy?
No. The super massive black hole at the center of the galaxy has about 4 million times the mass of the sun while the galaxy as a whole has at leas 1 trillion solar masses. In other words the black hole at the center of the galaxy accounts for about one twenty-fifth of one percent of the galaxy's mass.
Is anything has a mass greater than black hole?
Sure. For example, a galaxy has a larger mass.
How a star dies is determined by its age shape position in its galaxy mass?
No, how a star dies is determined by its mass.
Is hour world going to the center of the galaxy or what is the same black hole?
We (our Solar System) are going around the center of the galaxy; we are in orbit around the galaxy. This is not much different from the Earth going in an orbit around the Sun. The black hole at the center doesn't change anything; it is just one object more that has some mass - an insignificant amount of mass, compared to the remainder of the galaxy.We (our Solar System) are going around the center of the galaxy; we are in orbit around the galaxy.

What is located in the middle of our galaxy?
A supermassive black hole - with the mass of about 4,000,000 Suns.
Is a great part of the mass of the galaxy not visible?
Of course - most mass is not visible.
Can there be more than a black hole in a galaxy?
Yes. Most, of a galaxy's mass is stars and nebulae, not black holes.

When did Mass Effect Galaxy happen?
Mass Effect Galaxy happened in 2009.
When was Mass Effect Galaxy created?
Mass Effect Galaxy was created on 2009-06-22.
Do galaxies orbit an object?
Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.Galaxies form groups called galaxy clusters, so they would orbit the center of mass of the galaxy clusters, just as our Solar System orbits the center of mass of our galaxy.
Why are supermassive galaxies often found at the cores of rich galaxy clusters?
Because they have the most mass
Has a black hole ever been in hour galaxy?
I assume you mean "our galaxy". There is a supermassive black hole, with a mass that is about 4 million times the mass of our Sun, at the center of our galaxy.
What is the mass of the Andromeda galaxy?
The Andromeda galaxy has an Apparent mass of1.23 trillion solar-masses and contains 1 Trillion stars
What is a mass of stars called?
An isolated and distinct mass of stars is a galaxy.
What element makes up most matter?
Hydrogen is the most common element in our galaxy.
What is the galaxy is name in Mass Effect?
It is our galaxy the Milky Way. If you go to the Local Cluster you can look at Earth and in Mass Effect 1 you have a mission on the moon (Luna).
