Dark matter and The Force are not the same thing. The Force is a fictional power that connects all things. Dark matter is a real-world, theoretical matter that figures into physics and mathematics.

Can dark matter kill you?
The whole point of dark matter ... the thing that makes it "dark" ... is that it doesn't interact with normal matter except through the gravitational force (and, possibly, for some potential types of dark matter ... remember that nobody really knows what it actually is yet ... the weak force).One type of dark matter that we know about for sure is neutrinos. Around 65 billion neutrinos per second pass through every square centimeter of your body perpendicular to the direction of the Sun. They have been since you were born ... since before you were born, in fact. Even at night, because they go straight through the Earth too and come up through the ground on the side facing away from the Sun. The kajillion that have already done so haven't killed you yet, it's not all that likely that the kajillion and first is going to kill you.About the only reasonably possible way to die from dark matter would be if there were a lot of it concentrated in one smallish area, in which case you could be pulled apart by tidal forces if you were in a spaceship that went too close to it. This also isn't likely to happen.
What's the dark matter in the universe?
Dark matter is matter of an unknown type. It is known to exist, due to its gravitational influence, but it is not known what it is made of. There is at least 5 times as much dark matter than "normal" matter.
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
Where is located Dark Matter?
All over the dark expanse of space.
What is the ratio of dark matter to ordinary matter in a universe?
We're not certain that "dark matter" even exists, or what the proportions of "normal" to "dark" matter is. I have read some articles saying that the ratio might be as much as 20-1; 20 parts dark matter to one part normal matter, but these are predicated (I believe) solely on rough calculations based on the perceived mass of the galaxy and its apparent rotational speed.There appears to be a great deal of speculation and estimation in these calculations.One important trait of a scientist is to NOT GUESS about things that we don't know, and to admit the boundary between the known, the believed, and the unknown. Even if the current hypotheses about dark matter and dark energy turn out to have some basis in reality, we will certainly be surprised by the truth when we finally learn it.
What are the properties of dark matter?
Mainly that dark matter interacts with dark matter and with normal matter via the gravitational force; and that it DOES NOT interact with normal matter via any other known force. Or, if there is any interaction, it does so to such a small extent that it hasn't been possible to detect this so far.

Is gravity dark matter?
Gravity is not matter (dark or light), it is a property of mass and space that results in forces. Matter and force are entirely different things.
What is dark matter in the big bang theory?
Dark matter is matter that does not interact via the electromagnetic force. We don't really know what dark matter is, exactly; there are several possibilities. We know that it interacts via gravity, meaning it has mass. It may, or may not, or SOME of it may, interact via the weak force as well.
Is dark matter actually matter?
"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.
What kind of energy is matter?
The only kind of energy that dark matter is -- well, MATTER. Or mass, if you prefer, which is the same thing. We don't know what KIND of matter this stuff is, hence the name "dark." The only two things we know about dark matter is that (1) it interacts with baryonic matter via gravity but (2) it does NOT interact with baryonic matter via the electromagnetic force or the strong force. At this point, we're still working on what type of matter would do that.
How many people believe dark matter exists?
Dark Matter is required to exist because without it all galaxies would fly apart. In our Milky Way Galaxy Dark Matter accounts for 90% of the entire mass of the galaxy. Dark Matter is simply that, Dark. As it cannot be seen and has a very weak force. It only interacts with gravity.
What is the connection between magnetism and dark matter?
Not much is known about dark matter, but it is believed to interact with normal matter ONLY or ALMOST EXCLUSIVELY through gravitation; its interaction through the other forces (electric and magnetic forces, the strong force, the weak force) should be inexistent, or insignificant.
Why is it unlikely that dark matter is made up of stars?
Dark matter is by definition not visible nor reactive to the electromagnetic force; this would exclude visible matter, including stars. One might argue that the effects which dark matter has been used to explain could be consequential to gravitational pull from ordinary stars, perhaps owing to a gross miscalculation or an incomplete understanding of gravitational force -- but this would be a different position than to say dark matter itself is stellar material.
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.
IE = mc 2 I being information. Now we know what dark matter is. Observe it at a human sensory level it becomes normal matter. Could this be possible?
No, this is not possible. Dark matter is a form of matter that is undetectable by human senses, because it does not interact with any of the four fundamental forces that affect the visible universe (electromagnetism, strong nuclear force, weak nuclear force, and gravity). Therefore, it is impossible for dark matter to become normal matter as observed at a human sensory level.
How are stars dust and gas related to dark matter?
Stars, gas, and dust are all categorized as visible matter, not "dark" matter, but, since dark matter does not interact electromagnetically, the behavior of ordinary matter is used to study dark matter through their gravitational effects. You might say that stars, gas, and dust are like the leaves blowing in an invisible wind; the force can be perceived by the effects on the leaves even if you can't see the wind directly.
