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.
What else can I help you with?
Would an antimatter apple fall up?
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.
Can antimatter really blow up whole cities?
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.
What is a thing that's not made up of matter?
antimatter and dark matter
What do you say fall in turkish?
It could have many meaning, up to where do you use "fall" in English. It can be "düşmek, yıkılmak, sonbahar, yağmak, devrilmek" etc.
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 could it B true that matter and antimatter at start of big bang With little amount of matter left in end winning B enough 2 make up all we see today?
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.
Why is still antimatter in the universe if it was defeated by the matter in the big bang?
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.
How much is anti matter?
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.
What is an anti-down quark?
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.
How are the carbohydrates alike?
They are alike because they are both the same and they made up the same thing.
What does 'Fall off the wagon' mean?
It is an idiom meaning that someone who had stopped drinking alcohol has slipped up and started drinking again.
What is the existence of antimatter?
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
