Matter and Antimatter do they exist?

Answer 1

I just wanted to tell you the people that think 'Antimatter' is just science fiction really shouldn't be posting in the Astronomy and Space section, especialy under this topic, given that they have ABSOLUTLY NO IDEA WHAT THEY'RE TALKING ABOUT.

Anti-Matter isn't 'not matter' or whatever they're saying. It's the exact same kind of matter with the oppisite electrical charge.

An electron is a very small particle with a negative electrical charge and 1/2 spin. A positron is an electrons's anti-particle. It has the same weight and also has 1/2 spin, but it has a posative electrical charge. When the two particles touch, they annihalate eachother and covert their mass into energy, via E=MC^2.

Please.. Please.. PLEASE! If you don't know anything about Quantum Physics, don't answer peoples questions like you do. *bangs head against keyboard* XD

Answer 2

An extremely complex question of both science and philosophy! Matter only exists as we are able to percieve it according to our limited senses, ie: Sight, Sound, smell,Touch, Taste. Based on even these relatively limited sense perceptions we can say that matter does exist as we know it. Antimatter ,on the other hand, is a more scientific perception. Because we have to depend on tools with powerful abilities of observation, we can only wonder if we haven't created these devices with what we want to discover in mind. Leaving a minor problem with biased science. I petrsonally have faith in science and agree...YES matter and antimatter do both exist.

Answer 3

yes they do, in fact within the molecule it is trapped inside the the nucleus of an atom (Antimatter) which represents 50% of the total energy in the system. 25% is trapped by electron and 25% by protons. Electron traps the negative energy which is capable of producing thrust and pressure while the proton trapped the positive energy capable of creating magnetic attraction and the Neutral energy trapped inside the nucleus of an atom or pure energy or antimatter, this the main reason why the nucleus is heavily guarded by electrons and protons. to prevent it from escaping.

It can be noticed that during chain reaction the splits nucleus instantly seals off and become separate identity, the reasons for this is, the fragments of antimatter is converted to electron and proton and traps the residual Neutral energy which is capable of performing both the negative and positive energy, in the absence of creations it will procreate but in the absence it will annihilate. This because the electron and proton multiply rapidly creating another structural form of molecules which is dominant in the environment and occupy the space of the original molecules that bode and deranged it that renders it lost.

Answer 4

Anti-electrons are created regularly by normal radioactive decay, it's not the most commonly emitted particle but they're not uncommon.

Anti-protons are also created during some kinds of nuclear reaction.

Putting the two together to create anti-hydrogen is difficult, but it has actually been done by some experimenters. The trick is to slow the anti electrons and protons down after they've been created in order to allow the anti-electrons to be captured by the anti-protons, and to do this before they contact regular matter and get annihilated.

Anti-atoms of other elements have not, to my knowledge, been synthesized, however theoretically there's probably no reason why they couldn't be if enough time and effort was put into it.

Answer 5

Part of the big bang theory is that there were nearly equal parts of antimatter and matter but the vast majority was annihilated but there was more matter and that is what is left. I am not sure if I completely buy that.

Answer 6

Yes, although all the antimatter on Earth would be less than the head of a pin.

Answer 7

think of it like light and dark, action and reaction, every thing in the universe has its opposite so yes antimatter exists, we can even make it in SMALL quantities on earth, the center of the galaxy is full of it, if you go there try not to touch it :D

Answer 8

Yes but not together. Since than they meet, they destroy each other giving an electromagnetic wave of energy E=mc^2 where E =energy c speed of light , m mass of the two particles

Answer 9

Both matter and anti-matter do exist. Anti-matter occurs regularly in high-energy particles accelerators.

Answer 10

No.
Anti matter is a theoretical entity the would annihilate matter on sight. And itself.
The universe is made up of positive and negative but not anti.
