By definition dark matter isn't something you can see. In scientific terms you might say it possesses mass but doesn't interact electromagnetically, that is, it does not absorb or emit light. This makes it hard to study; however, its effects are visible in somewhat the same way that wind is invisible but dust and leaves blowing in it can be seen: studies in the behavior of galactic and galactic cluster rotation hint at its presence, as do observations of cosmic background radiation and gravitational lensing. Particle physicists continue to search for a particle which would be a good candidate to explain this type of matter; alternative theories for its effects not involving matter are being developed.

∙ 12y agoWe know that dark matter exists because it got gravity, though it is invisible. It hold galaxy and Universe.
There is a theory there many other parallel universe outside our universe and dark matter holds those universe up and some scientists says that dark matter are just mass of the matter of the parallel universe. It sounds crazy but that is the Law of Physics.
However there is not exact explanation of what dark matter really is, so there are still Noble Prices for those who can come up with a reasonable explanation

∙ 14y agoThere is at least 5 times as much dark matter than normal matter. "Normal" matter in this case includes all matter of known composition, including stars, interestellar gas and dust, and even black holes.

∙ 14y agoDark 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.

I think it consist of energy. ( Just my dumb guess)

What a space contains?
whatever you put in that space. If you are talking about the space (Outer Space) then there are planets and moons and stars and stuff, too much for your puny brain to understand
What is the heaven and earth made out of?
If by "heaven" you mean outer space, it is made up of the same 90 elements or so that are found on Earth. However, in outer space there is also matter that is not made up of atoms - including black holes, dark matter, and dark energy.If by "heaven" you mean a metaphysical heaven, as in what expects us in the afterlife - well, nobody really knows.
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 area of invisible space around us called?
It is called dark matter. Dark matter is undetectable and invisible.
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.

If outer-space is a vacuum and there are no gases that make outer-space then what elements makes outer-space what outer-space is?
Most gases condense and then freeze in to solids in space because of the extremely low temperatures but any gaseous material that doesn't freeze will be dispersed so much that its presence is negligible. A vacuum is a space with no 'matter' present in it, so NO elements make outer space and it's virtually empty of matter. If you strictly mean outer space as in the space directly above our earth then according to Wikipedia... "...contains a low density of particles, predominantly hydrogen plasma, as well as electromagnetic radiation, magnetic fields, and neutrinos. Theoretically, it also contains dark matter and dark energy." Dark matter is something else entirely, and it's matter, not energy (dark energy being something else again). Since it's matter it creates its own gravity which is something we need apparently, well 'we' don't 'need' it but scientists concerned with the study of space (for example; astronomers, astrophysicists, cosmologists etc.) require it to explain the apparent lack of gravity from visible matter (ie. stars, planets and other 'bodies' or 'objects' in space) to account for the positions of stars and galaxies. I don't think it is possible to create a complete and total vacuum that has absolutely NOTHING in it, no light, no sub atomic particles, no dark matter or energy. Makes me wonder though, if they do exist naturally in space and what it would mean.
What is a negative space?
Negative space is dark energy and dark matter.

What occupies space?
Matter occupies space. Also dark matter does too.
Is matter being transformed into space by black holes?
No, when the big bang happend dark matter and dark energy came. Dark matter expands space even as we speak.
What is space that has no matter?
Dark energy.

What is space mostly made of?
Dark matter.
Where is located Dark Matter?
All over the dark expanse of space.
What is the area of invisible space around us called?
It is called dark matter. Dark matter is undetectable and invisible.
What does it mean that dark matter warps time and light?
Since dark matter has mass, it is able to warp time and space, which also makes it able to bend light. The effect of dark matter on space-time (and, therefore, light) is the same as that of regular matter.
