If that blows your mind, look up the wiki article on positronium. It's an exotic 'atom' consisting of an electron and a positron in a binary orbit with each other. I might look for this later, but there is also a fascinating paper on what the universe will look like in the distant future that says that when nearly all matter is gone and the only thing left are photons and electrons/positrons, there will be atoms of positronium as large as the observable universe. Which is to say, matter will be so sparse that an electron and a positron will be able to attract each other from across the universe and spiral in toward each other, and after an unimaginable length of time, eventually meet and annihilate.

Bear Creek An antimatter bomb would definitely be powerful. But the problem would be actually storing antimatter for any meaningful period of time to make it usable in any kind of explosive. Radioactive substances like uranium can work if they don't decay too quickly (And some uranium isotopes have pretty love half-lives), and because they don't annihilate matter like antimatter does. Unless a method of storing antimatter for a reasonable amount of time is found, antimatter bombs are impractical. And don't get me started on the cost.

Since all particles exhibit wave-particle duality, is matter-antimatter annihilation a consequence of destructive interference? I mean, with all waves, the wave disappears when combined with one with an opposite polarity, but all energy is conserved. It's just like with matter and antimatter.

@2warstwy 8 жыл бұрын
Hans Fischer I think the same ,both- H and O is made from the same smaller particles - protons, electrons and neutrons. so they will simply annihilate, but not all... Oxygen is made from 8 protons, 8 elektrons and 8 neutrons, Hydrogen is made from 1 proton and 1 electron... So 1 proton , 1 electron , 1 anti-proton, 1 anti-electron disapper and we will still got 7 anti protons, 7 anti-electron and 8 neutron. Mass number of this particle will be 7+8= 15. Atomic number of this particle : 7. So Anti-oxygen will become anti-Nitrogen atom... Hmmm we still need physicist to say am i wrong at this one :)

I have a thought. That antiprotons, and positrons they are also matter that can be turned into energy. If for example when a PET medical scanner uses the properties of positrons. The fact the anililation happens creating energy that can be detected by the machine. Mass and energy are related (E =MC SQUARED). As stated Cern can produce antihydrogen, antiprotons, and positrons and using magnetic field to direct them, and store them. Cern uses protons at nearly the speed of light to smash it a metal plate and some anti protons are produced. The Sun also has high temperatures, and explosive pressure's which might produce antiprotons that are anililation strait away causing energy to be produced. Keeping the Sun burning.

Ok, so I've been really obsessed with antimatter now. I found out while investigating that if there is no way of annihilating it with matter, you can actually have structures of these. I still don't know if I'm right though... so I have these questions: 1) Could there be a universe made out of antimatter and few matter hypothetically speaking? 2) Are the primary colors of light of antimatter the opposite of those of matter? 3) Are black holes made out of antimatter? If yes, are they antimatter stars? If so, is part of they're pull because matter is attracted to antimatter and viceversa? 4) Is there any possibility gravity works the same for both types of matters since they're only opposite in charges and color, but not in the fact that both occupy mass and curve space-time? 5) And last but not least, can we even answer those questions yet? I did a mess right there, but hopefully someone will fill this knowledge-thirst human with information o.o
@taichitai 9 жыл бұрын
First thing to declare is that i am in no way a professional physicist or anything close to being that, hence the answers below are to the best of my knowledge and I apologize in advance for any errors. 1) Q:Could there be a universe made out of antimatter and few matter hypothetically speaking? A: Technically, both antimatter and matter can form individual solar systems on their own. Both can exist in the same universe, as long as they are not in contact of each other (e.g. lights years away from each other like the current distance between us and the closest solar system). As for differents universes that you are talking about in your question, I believe it will involve the frontier fields of physics in string theory as to the types of universe and so on. Hence, the simple answer is that yes, both can exist in the same universe as long as they do not come in contact with each another. As the the question of universes, we are still unable to test the types, or even if there is an existence of the multiverse (multiple universe) although the maths seems to be pretty sound with regards to the multiverse theory. 2) Q: Are the primary colors of light of antimatter the opposite of those of matter? A: This will involve the understanding of what is primary colors are. This would be better named as the human primary colours as humans only have 3 different colour receptors (red, green, and blue) in our eyes. The reason why we can see so many colours is that our brain takes the information from the 3 receptors and infer what the actual colour of the object is. An example is that a dog only has 2 receptors, so the primary colours for dogs will be these 2 colours instead. Hence, as there is no change in our eye's receptors, we will still see the same primary colours for antimatter or matter alike. 3) Q:Are black holes made out of antimatter? If yes, are they antimatter stars? If so, is part of they're pull because matter is attracted to antimatter and viceversa? A: Black holes are formed when an object attains gravity so high in a small point that it rips apart the fabric of space-time causing a singularity. As long as you are able to create such a high gravity on a small point (no matter is it matter or anti-matter), you will get yourself a black hole. Also, no objects, matter and antimatter or even light can escape the pull of the black hole if it is close enough to the black hole. It probably gobbles up antimatter and matter the same way, not a picky fellow when it comes to gobbling things up. 4) Q: Is there any possibility gravity works the same for both types of matters since they're only opposite in charges and color, but not in the fact that both occupy mass and curve space-time? A: Gravity should probably act the same way under our current known theories as it is not known that antimatter has any special properties when it comes to mass and gravity. However, if this is not yet tested in experiments or at least it is currently being tested, the hope is that it will be different and hence give us a hint for the future progress of physics as our current physics system is definately not complete as it is unable to unify relativity (gravity) with quantum mechanics. You might wish to take a look at the double slit experiment into understanding why results that differ from our current theories might actually be beneficial to physics. 5) Q:And last but not least, can we even answer those questions yet? A: We are mostly able to or undergoing the process of confirming the answers to these question, but the millions dollar question is still how do we unify relativity (gravity) with quantum mechanics.

To describe someone you would need many different labels like their height, weight, eye color, Etc. The same thing applies to the different particles which make up the standard model. These labels are called quantum numbers. They include electric charge, color charge, baryon number, lepton number, lepton family number, Spin, angular momentum, weak isospin. These labels can be used to describe every particle known to exist. In all particle interactions, you can think of quantum numbers like energy: something that can neither be created nor destroyed, only transferred. Thus, if a collection of particles has +10 units of electric charge, no matter what new particles are produced, the end net electric charge must remain +10. In energetic processes, namely fission and fusion(relying on primarily the strong interaction), all of the particles are the same type and thus possess the same quantum numbers. Since the numbers don't add up to zero, this prevents 100% of mass turning into energy.

By the very definition of the law of conservation of energy you are then restricted from getting more than that amount back. So if we look at fueling the spacecraft with anti-matter, everything is great, but you're not getting anything more than you put in (well actually more than twice of what you put in, if you destroy the equal amount of regular matter).

@2344553 Mass is conserved as the matter is transformed to another form of energy, i.e electromagnetic waves (gamma rays) for electrons/protons and this wave can be transformed back into the given particles (theoretically).

That is a very interested approach, I will agree with you that this is the only way we can think of now.. I wish we find another way in the near future, a lot easier to us.

Electrical power is basically kinetic energy carried by electrons. A particle and its antiparticle have opposite charges but equal mass. Charge determines how much the particle is accelerated by an electric field just like mass determines the same for a gravitational field. In any given field, a positron would have the same speed and therefore the same kinetic energy as en electron, but they would be going in opposite directions. So it would be like regular current, except for flowing backwards.

ive been wondering what would happen if one was able to combine 2 antihydrogens and 1 antioxygen... would they bond to form antiwater... just some thoughts

It is the locational spherical inward absorption density + and -outward emission density of electromagnetic waves that's forming all forces of nature and everything forming antimatter matter annihilation or energy and mass forming positive and negative electric charge and electromagnetic fields, input+0/1-output or resonance and interference now as time unfolds from that individual ref-frame. Time is inverse multiplying+/-dividing or like frequency and wavelength thus can speed up or slow down.

"Matter is in violent motion simulating rest and balance now through violent motion. Interchange between these two unbalanced opposites is the basis of all motion in this rythmic universe. It is the locational Spherical inward absorption and outward emission of EMR, or light thats forming antimatter matter annihilation forming + and - electric charge and electromagnetic fields as time unfolds. It is the inward absorption and outward emission of EMR thats forming the inward force called gravity."

So, if you managed to combine enough antimatter to make some radioactive atom, like anti-Uranium for instance, what would it radiate? Would it be regular old α β and γ radiation? Or would it be something like the opposite?

It takes more energy to make the antimatter in the first place than you would get out of it. Pretty good for energy storage density tho', if you can contain it appropriately it'd make a great battery replacement.

@Dodo385 No, they have opposite charges and would attract each other and then anihilate.

@DeathG4n Yes, but that requires antimatter in a massive scale and it's pretty much impossible to make antimatter without using more energy that you would get from annihilating it.

To be specific, faster than c does not seem to be possible, at least not as we understand velocity. FTL in a given medium is certainly possible, if not necessarily attainable yet

But what is antimatter? What changed so the anti-electron (the positron) now has a positive charge? We know that particles spin anti-clockwise, does the anti-particle spin clockwise? Considering that this change in direction seems to account for the particle-antiparticle differences, like charge conjugation (charge reversal), parity (reversal of direction in space or coordinate system) and time reversal. We would love if you could elaborate more on that.

@flakemusic86 i think you are referring to Uranium - 235, but it does not have 235 neutrons, rather 235 nucleons (neutrons + protons). The element Uranium has an atomic number of 92 and therefor always has 92 protons, but U-235 has 143 neutrons. Ba-139 and Kr-95 also do NOT have 139 and 95 neutrons respectively, rather those numbers represent the mass numbers of those specific isotopes

@SuperFinGuy so then then this energy is then spread out/released... rather than ceased to exist or decay? Atom is ripped apart, but electrons protons released? thank you for your response...

@basslinet creating and storing, according to video. Okay, i woudn't be sure about its visibility anyways. We know too few about anti-particles, so they might as well pass the light unaffected. Thanks for your opinion, though.

"it has no charge thus there is no difference".The "anti" is not just about charge, antimatter has both the opposite charge and spin. There's antineutrons too, for instance, and they have no charge either, but they do have spin.

Yes. Antimatter is exactly the same as normal matter. It's a mirror image that when it meets with matter, it obliterates it, but otherwise, it's perfectly identical in physical properties.

Dan Brown taught scientists a very valuable lesson; when you find something really cool like say THE OPPOSITE OF MATTER AS WE KNOW IT and it just so happens to ANNIHILATE WHEN IN CONTACT WITH REGULAR MATTER you should probably let everyone know.

one way to produce antiprotons is to smash two protons together so fast that the collision produces three protons and an antiproton. The two extra particles are created from the kinetic energy of the fast moving protons. They can also be produced by firing a proton beam at a rotating nickel target.

We are talking about positrons annihilating electrons. It is natural for an atom to temporarily lose an electron or two, chemical reactions happen because of this. There are electrons everywhere, the ones you destroy are immediately replaced, you aren't doing any damage from that. If you were annihilating protons though, it would be different.

No, you still need a lot of neutrons (or antineutrons, not sure if those are different from neutrons)

Would a positron and a proton react? Would anti hydrogen react with helium? Or is it just positron-electron, proton-anti proton etc? What about tau electron and positron? Is there an attraction between particles and anti particles? Is there a force (ie if you have a cannon shooting positrons and one shooting electrons aligned in parallel, will the beams curve towards each other?
