No, dark matter is entirely different from antimatter. For one, we know a lot about antimatter and have been able to do experiments with it and actually utilize it in some nuclear reactions.
Dark matter is a theory to help understand why the universe does not behaive the way we believed it should. Galaxies are showing that they do not have enough mass to have the gravitational effects that they do, so there must be matter somewhere, this is labeled as dark matter.
What else can I help you with?
In an atom of antimatter what would be the charge of an electron?
An atom of antimatter does not contain any electrons. The equivalent of an electron in antimatter is a positron, which has charge +1.
What is the difference between anti matter and dark matter?
Antimatter is actually matter that can be considered going back in time. Negative matter is matter that has negative gravity properties. In other words, Negative matter repels things. Negative matter is also theoretical, not proven. Antimatter has been (and is being) made.
Can elements be made out of antimatter?
Yes. Antimatter is only a point of view concept : we can imagine any object made of what we call antimatter. According to his point of view, we would be made of antimatter. Moreover, a number of large areas of the universe, that doesn't have any contact with each other, may be made of antimatter. we wouldn't have any mean to know from where we are.
Is there any way to get samples of dark matter?
NO we can not get the samples of dark matter as it is the type of matter in astronomy and cosmology that can not be even seen with telescopes.
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.
How come the universe is made of matter and not antimatter?
That is not currently known. There is a slight assymetry between matter and antimatter, but so far, it seems that this assymetry is not enough to explain why there is only matter, and hardly any antimatter, in the Universe. Without such an assymetry, there wouldn't be either matter or antimatter in the Universe - just radiation. For more information about what is known, and what isn't, check the Wikipedia article on "Baryon asymmetry".
Will antimatter start a black hole?
No, Antimatter while annihilate our matter, meaning that it will completely convert our matter to light and heat, however antimatter is highly theoretical, and the LHC probably will not create any.
What is the difference between antimatter and dark matter?
Antimatter is the opposite of normal matter, with particles having opposite charges. Dark matter is a mysterious substance that does not emit light or energy, but affects the motion of galaxies and other cosmic structures through gravity.
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.
Was the explosion out of antimatter?
Current physical theory tends to indicate there should be a symmetry expressed in the form of a parity between matter and antimatter created in the Big Bang, with no preference for matter over antimatter; this explosion should have created equal amounts of both, which would then annihilate each other. However, the universe tends to be dominated so far as we can tell by matter and no significant regions of antimatter have yet been detected. This would indicate an asymmetry or bias in favor of matter's creation, which is somewhat mysterious and remains a subject of research. In any case, this bias of matter over antimatter is believed to be extremely small - such that it may have been for every billion particles of antimatter created, there were a billion and one particles of matter.
In an atom of antimatter what would be the charge of an electron?
An atom of antimatter does not contain any electrons. The equivalent of an electron in antimatter is a positron, which has charge +1.
What is the difference between anti matter and dark matter?

Is antimatter real?
Yes it is. This does not mean that it has the properties ascribed to it in any particular work of fiction (Star Trek's version is reasonably realistic, Green Lantern's version is hopelessly silly), but yes, something by that name does really exist. ************************************************************************* Antimatter is real. Some scientists believe that antimatter is a perfect symmetry to matter. Antimatter is very dangerous and powerful. When matter and antimatter collide, an annihilation happens. Things around it will disappear.
How is antimatter stored and maintained to prevent annihilation upon contact with matter?
Antimatter is stored in specialized containers that use magnetic fields to keep it away from regular matter. This prevents annihilation, which occurs when antimatter comes into contact with matter, releasing a large amount of energy. The containers are kept in a vacuum to minimize the chance of contact with any particles. Additionally, the containers are cooled to very low temperatures to slow down the movement of the antimatter particles, reducing the likelihood of annihilation.
Is there any proof that antimatter exists?
Yes, antimatter has been observed in laboratory experiments and high-energy particle collisions. The existence of antimatter is supported by the theoretical framework of quantum field theory, which predicts the existence of antimatter as a counterpart to ordinary matter. Additionally, antimatter has practical applications in medical imaging and research.
How many grams of antimatter are needed to react with 5 g of matter?
Exactly 5 grams of antimatter will completely annihilate 5 grams of matter, producing an enormous shower of high energy gamma rays. In total a mass of 10 grams will be converted to the equivalent amount of energy.
If an antimatter star went supernova near your solar system would it be any different than a regular supernova?
The observable universe is almost entirely matter (as opposed to antimatter) so it's unlikely that a cloud of antimatter large enough to form a star could exist long enough to form a star anywhere near the solar system; it would be annihilated by collisions with neighboring normal matter. Ignoring that, though, yes, there would be differences. The ejecta of an antimatter supernova would be primarily antimatter, meaning that it would annihilate nearby normal matter and give off massive amounts of gamma radiation that would not be seen with a normal matter supernova.
