What happens if anti matter 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).

Why is dark matter not antimatter?

The key is that our universe is mostly made of regular matter, so antimatter cannot stick around for very long. Dark matter is matter that does not interact electromagnetically, and therefore cannot be seen using light.

Does anti matter fall up?

But some theories predict new, as yet unseen forces: these forces would make antimatter fall differently than matter. But in these theories, antimatter always falls slightly faster than matter; antimatter never falls up.

Can matter and antimatter coexist together?

The obvious answer is no. Matter and antimatter would annihilate each other. However, they can ‘coexist’ for a brief amount of time before annihilating. There is a particle called the positronium, which is a temporary system consisting of an electron and a positron in orbit around each other.

Why is there more matter than antimatter in the universe?

So why is there far more matter than antimatter in the universe? The Big Bang should have created equal amounts of matter and antimatter in the early universe. But today, everything we see from the smallest life forms on Earth to the largest stellar objects is made almost entirely of matter. Comparatively, there is not much antimatter to be found.

Why do antiparticles decay more often as matter than antimatter?

Researchers have observed spontaneous transformations between particles and their antiparticles, occurring millions of times per second before they decay. Some unknown entity intervening in this process in the early universe could have caused these “oscillating” particles to decay as matter more often than they decayed as antimatter.

Is it possible to convert antimatter to energy?

Yes, it is possible, but only if you contain the antimatter in a magnetic bottle. If just one gram of antimatter were to come in contact with just one gram of matter, you would get 100\% conversion of matter to energy. I am not sure of the exact calculation.
