Suppose there were an intelligent lifeform that was made out of antimatter. What would happen if it came in contact with life made out of matter? Could it come close to a matter being? What would happen if it touched a matter being?
Could a matter being have a conversation with an antimatter being as long as they never touch each other? Or could they not even be close to each other?Matter stuff and antimatter stuff annihilate each other when coming into contact. It doesn't matter if the stuff is living or inanimate as long as it is made of the equivalent material - matter consisting of protons, neutrons, and electrons, and antimatter consisting of the equivalent antiparticles.
Well you'd need an atmosphere if we mean talking, which means there must be molecules of either matter or antimatter so one of them would be vapourised, the other would then recieve a nice amount of ionising radiation.Could a matter being have a conversation with an antimatter being as long as they never touch each other?

Antimatter has almost the exact same properties as normal matter with the exception of charge. For example, you CANNOT tell the difference between an Electron and its anti particle, the Positron, except that the Positron is POSITIVELY charged while the electron is negatively charged. They most definitely attract each other since they are oppositely charged.hello...i have got a basic question.....does matter attract of repel antimatter...??
Opposite charges attract, same charges repel. So proton & antiproton attract, while proton & positron repel.hello...i have got a basic question.....does matter attract of repel antimatter...??
Nice, I wonder what happens when something bigger than an atom like an organism from the anti matter and regular matter world collides.Opposite charges attract, same charges repel. So proton & antiproton attract, while proton & positron repel.
Gravity will still be attractive, but you'd need a large amount to notice.
I just realized I need to clarify a bit.but you'd need a large amount to notice.
As you get bigger amounts, you get bigger explosions. If those two kilograms reacted, they'd release 43 megatons of energy.

This is why people who have PET scans cannot go near pregnant women for an hour or so after the therapy!During a PET scan, the patient is injected with radioactive tracer molecules that emit positrons when they decay. These positrons then come into contact with electrons in the body, and the two annihilate, releasing two gamma-ray photons. The gamma-ray photons are then detected by the scanner, giving a 3-D image of what's going on inside the body.
