Can someone explain anti-matter or the theory of anti-matter to me?

Question

Is it a misconception? Is it already created or exist? Is it plausible?

Answer 1

Anti-matter exists. Einstein's theory of relativity, combined with quantum mechanics, gave us the clues that led us to believe anti-particles existed. To understand anti-matter, you have to understand relativity and quantum mechanics separately, then understand how Dirac tried to combine both theories.

Relativity theory describes a universe where velocity--how something is moving--affects how the object experiences the flow of time. To put it in a very simplified way, according to the theory, two objects moving at different speeds perceive time to pass at different rates. This is a byproduct of a fundamental assumption: that light is the mechanism by which material objects interact at the microscopic level, and that movement affects the interaction of objects with light originating from other objects.

Quantum mechanics describes how the measureable properties of objects--such as their velocities--are limited by the fact that energy can be transferred only in fixed amounts. It also assumes that light is the fundamental means of energy transfer between objects.

In other words, you need some calculus, linear algebra, and complex number knowledge to interpret what Einstein and Dirac are talking about.

The net result was that Dirac found that combining the two theories brought about a concept of "negative energy" which predicted the existence of anti-matter.

If that's not confusing enough, anti-matter can also be thought of as moving backward in time.

It sounds like make-believe, but we can synthesize anti-matter in the laboratory.

And some natural radioactive materials give off anti-electrons as part of their naturally occuring decay process.

These radioactive materials are used often in "positron-emission tomography," called "PET scans." It is a method of imaging the interior of the body. A patient is given a dose of the radioactive material. The material emits anti-electrons, which collide with normal electrons in the patient's body, and when particles collide with anti-particles, both normal and anti-particles are converted into photons (pulses of light).

So the reaction in the patient's body causes pulses of light that can be detected using sensors outside the body. This is then mapped by a computer to produce an image of the body's interior. This is different from x-ray imaging, since x-rays are generated *outside* the body and directed through the patient.

These theories sound weird. They are mathematically complex. But they "work" in so far as we can "do stuff" with these theories.

Answer 2

Antimatter is quite real, and it has been manufactured in very small amounts in physics research centers. Most particles have an antiparticle.

For example, the electron has a -1 charge. The electron's antiparticle is called a positron. It is exactly like an electron in every way (it has the same mass), but it has a +1 charge instead.

The proton (+1 charge) has an antiparticle called an antiproton. It has the same mass as a proton, but a -1 charge instead.

The antiparticle of the neutron (0 charge) is the antineutron, which also has 0 charge, and the same mass.

When a particle and its corresponding antiparticle meet, they annihilate each other and disappear completely. In their place, you end up with a pair of photons (light particles). For example, an electron and positron will attract each other because of their opposite charges. When they meet, they both disappear, and two high-energy photons are created.

Antimatter is extremely difficult to store, because you can't let it touch the walls of the container. If it touches the walls, it will almost certainly find its corresponding particles, and annihilate.

Answer 3

Many scientists believe that these matter / anti-matter pairs are spontaneously being created and destroyed everywhere all the time including in empty space. If String theory is true for every particle there is an antiparticle. You never come in contact with anti-matter as if it ever contacts its matter component (with an opposite spin) both particles will be eliminated.

Cool huh? Buy Stephen Hawkings' Universe in a Nutshell. It has all kinds of cool theories like that but with sweet pictures too, unlike my trendy smiley face :)

Answer 4

rely is made up of protons, electrons and neutrons. The proton has an excellent value, the electron has an equivalent detrimental value, and the neutron has no value. Protons and neutrons huddle in a nucleus of the atom on an identical time as electrons flutter around the nucleus in tiny orbits. lots of what i'm telling you alter into confirmed by elegant experiments in the nineteenth century. we've everyday for some years that there are an entire opposite solid of characters, between them, a negatively charged proton and a certainly charged electron. needless to say those debris will deliver at the same time into atoms basically as our primary adult men will -- different than that their costs stands out as the alternative. yet another issues all of us know is that once 2 opposite debris meet, they annihilate one yet another, turning them into organic capability. So in case you have been waiting to create a tiny quantity of fabric made up of those anti-debris, that would desire to be anti-rely, and it may directly replace into capability while it made touch in any way with any known rely.on the enormous bang, textile of the two kinds replace into created, and little by little they annihilated one yet another, transforming into extensive quantities of capability alongside the way. in basic terms, by some little bit of hazard, there looks to have been in basic terms a p.c. or so greater of rely than there replace into of anti-rely, so the universe as all of us realize it right this moment is made up of that tiny share distinction. wish this enables. Google will ingredient you to quite some thrilling data in this in case you want to verify greater. basically make confident the positioning you're finding at isn't made by some lunatics. i did not say non secular nuts!! i did not! i did not!

Answer 5

Anti-matter is a type of matter made of anti-particles. These particles have the same mass as their "normal" counterparts; particles, but they have opposite charge and, i think, opposite spin too. They annhilate each other when they meet.

Answer 6

I think a black-hole is anti matter.
It does exist, we cant harness it. Thats all I really know about it.
