It means that the possibility is considered that Earth's gravity (for example) would push such antimatter up, instead of down; thus, an object made of antimatter, if initially at rest, would move away from Earth, faster and faster. This is a possibility that is being considered; it doesn't seem very likely, though.
No, and antimatter apple would not fall up. It still applies to the same laws of physics, but the only variation is is when it makes connection with it's opposite charge, then the antimatter annihilates both itself and the particles that I connected to.
yes, antimatter can blow up whole cities. it only takes the amount of a grain of sugar to blow up an entire city the size of New York City.
antimatter and dark matter
CERN studies antimatter to deepen our understanding of the fundamental forces and particles that make up the universe. By investigating antimatter, scientists aim to explore why there is an apparent imbalance between matter and antimatter, a mystery that could shed light on the origins of the universe. Additionally, experiments with antimatter could have practical applications, such as advancements in medical imaging and potential energy sources. Understanding antimatter also tests the predictions of the Standard Model of particle physics and may reveal new physics beyond it.
It could have many meaning, up to where do you use "fall" in English. It can be "düşmek, yıkılmak, sonbahar, yağmak, devrilmek" etc.
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.
It is not currently known why there is more matter than antimatter. Some assymetries (differences between matter and antimatter) have been found, but they are very slight, and it is not clear how this could have been enough to create the matter we see today.
Antimatter is an extremely rare and expensive substance to produce. Estimates suggest it can cost billions of dollars per gram to produce antimatter. Its high cost is due to the complex processes required to create and store it.
Our current understanding says that matter-antimatter pairs can be produced by a sufficiently strong energy field, and further says that this is happening all the time. Normally these particles quickly meet up and annihilate each other, but under certain conditions this might not happen, which would leave free antimatter particles running around.
An anti-down quark is the antimatter counterpart of a down quark, one of the elementary particles that make up protons and neutrons in the atomic nucleus. It has opposite electric charge to a down quark and can combine with other quarks to form antimatter particles.
They are alike because they are both the same and they made up the same thing.
Previous answer "The existence of antimatter is just a lower less advanced form of dark matter" this is completely wrong, Antimatter is quite the opposite of 'normal' matter. It is made up of positrons that orbit around the nucleus in shells and have a positive charge. Anti-proton (a proton with a negative charge) and neutrons stay the same as they have no charge and are in fact neutral. dark matter is simply matter that doesn't give out light
