The key is that our universe is mostly made of regular matter, so antimatter cannot stick around for very long. Very soon after antimatter is created, it bumps into regular matter and gets destroyed again. ... Dark matter is matter that does not interact electromagnetically, and therefore cannot be seen using light.

Is dark matter the same as antimatter?
Two of the most intriguing mysteries in modern cosmology are the apparent preponderance of ordinary matter over antimatter and the nature of dark matter, which accounts for about 85% of the mass in the Universe1. Dark matter has made its presence known only through its gravitational effects on astrophysical objects.
Can antimatter destroy dark matter?
If dark matter is made of regular WIMPS, when two WIMPs meet at the center of a star they would destroy one another, because they are their own antimatter counterparts. ... If two of these like particles met, they would not annihilate, so dark matter would simply build up over time inside the star.
What is the difference between matter and antimatter?
Antimatter is identical to normal matter in almost every way. The only difference is electric charge, which is opposite for the two forms of matter. ... Most theories say the Big Bang should have created equal amounts of matter and antimatter.
What is the opposite of dark matter?
Antimatter is the same as matter in every way, looks the same, behaves the same, except its particles have electrical charges opposite to matter. E.g., our electrons are negatively charged, whereas a positron (an antimatter "electron") is positively charged.
Do we have dark matter in our bodies?
Even though, at any given instant, there's only around 10-22 kilograms of dark matter inside you, much larger amounts are constantly passing through you. Every second, you'll experience about 2.5 × 10-16 kilograms of dark matter passing through your body.
How dangerous is antimatter?
A gram of antimatter could produce an explosion the size of a nuclear bomb. However, humans have produced only a minuscule amount of antimatter. ... If all the antimatter ever made by humans were annihilated at once, the energy produced wouldn't even be enough to boil a cup of tea.
Why is antimatter so expensive?
Due to its explosive nature (it annihilates when in contact with normal matter) and energy-intensive production, the cost of making antimatter is astronomical. CERN produces about 1x10^15 antiprotons every year, but that only amounts to 1.67 nanograms.
What would happen if antimatter hit a black hole?
No. Antimatter has positive mass just like ordinary matter, so the black hole would merely get larger and heavier. Whatever fireworks happened inside the hole, if the anitmatter met up with ordinary matter there, would have no effect on the hole's total matter-and-energy content or, therefore, its mass.
What does antimatter look like?
When you see antimatter depicted in science fiction movies, it's usually some weird glowing gas in a special containment unit. Real antimatter looks just like regular matter. Anti-water, for example, would still be H2O and would have the same properties of water when reacting with other antimatter.
Can we see antimatter?
Most matter observable from the Earth seems to be made of matter rather than antimatter. ... The presence of the resulting antimatter is detectable by the two gamma rays produced every time positrons annihilate with nearby matter.
Can antimatter destroy the world?
Will the mutual annihilation and conversion to pure energy destroy the world? No, say physicists. ... But in the history of the world, we've only created such a tiny, tiny amount of antimatter that if you were to annihilate it all at once, you wouldn't have enough energy to boil a cup of tea, let alone blow up anything."
What happens if antimatter touches matter?
Whenever antimatter meets matter (assuming their particles are of the same type), then annihilation occurs, and energy is released. In this case, a 1 kg chunk of the earth would be annihilated , along with the meteorite. There would be energy released in the form of gamma radiation (probably).
