Antimatter interact with massive matter through gravity.

In summary, antimatter has the same gravitational properties as matter and interacts with it in the same way. Despite being stored using electromagnetic fields, it still has weight and can be measured. Antimatter behaves like normal matter, except for having the opposite charge. It is not the same as dark matter, which is a separate concept. Antimatter is not as exotic as it once was and can be seen in everyday life. However, it takes a significant amount of time to produce even a small amount of antihydrogen.

How does antimatter interact with massive matter through gravity. Does it still attract? I know most antiparticles are stored using electromagnetic fields so we wouldn't see the effect of gravity, but have we ever just let one loose and seen if it falls to the earth?

Antimatter has gravity and interacts with gravity exactly like matter does.

And, despite being stored in a magnetic bottle, we can still tell that it has weight. (A box containing a magnetic bottle that's suspending one kg of antimatter weighs one kg more than a box containing a magnetic bottle that's suspending nothing.)

antimatter behaves in every way like normal matter in terms of gravity. They just have the opposite charge relative to the normal species (i.e. positrons have +e charge where electrons have -e charge). You may be confusing anti-matter with dark matter which are very different things. We see anti-matter all the time and, these days, there's really nothing particularly exotic about it.

erm... You lead a much more exciting life than most of us...

atw*:"...it would take two billion years to produce 1 gram or 1 mole of antihydrogen..."

*according to wiki

1. What is antimatter?

Antimatter is a type of matter composed of particles that have the same mass as their corresponding particles in regular matter, but with opposite electrical charges.

2. How does antimatter interact with regular matter?

Antimatter and regular matter can interact through the fundamental forces of nature, such as electromagnetism and the strong and weak nuclear forces. However, when they come into contact, they annihilate each other, releasing large amounts of energy in the form of photons.

3. How does antimatter interact with massive matter through gravity?

Antimatter and regular matter also interact through the force of gravity. Just like regular matter, antimatter has mass and therefore exerts a gravitational force on other objects. This force is the same as the force exerted by regular matter of the same mass.

4. Can antimatter be used as a source of energy?

Yes, the annihilation of antimatter with regular matter releases a huge amount of energy. However, it is currently very difficult and expensive to produce and contain antimatter, so it is not a practical source of energy at this time.

5. What is the potential impact of studying antimatter?

Studying antimatter can help us understand the fundamental laws of physics and the origins of the universe. It can also have practical applications in fields such as medical imaging and cancer treatment. Additionally, research on antimatter can lead to advancements in energy production and propulsion systems for space travel.
