Theoretically, there could be people and planets made out of antimatter rather than matter, but where are they?
---------------------------------------------------
MICHIO KAKU:
Dr. Michio Kaku is the co-founder of string field theory, and is one of the most widely recognized scientists in the world today. He has written 4 New York Times Best Sellers, is the science correspondent for CBS This Morning and has hosted numerous science specials for BBC-TV, the Discovery/Science Channel. His radio show broadcasts to 100 radio stations every week. Dr. Kaku holds the Henry Semat Chair and Professorship in theoretical physics at the City College of New York (CUNY), where he has taught for over 25 years. He has also been a visiting professor at the Institute for Advanced Study as well as New York University (NYU).
---------------------------------------------------
TRANSCRIPT:
Question: Is it possible for antimatter to form complex structures such as molecules or even entire life forms? (Submitted by Ron Or-El)
Michio Kaku: Ron, you ask a very interesting question. In fact, and I was in high school, I used to play with antimatter. It turns out that sodium 22 naturally emits positrons or anti-electrons. I put the antimatter inside a cloud chamber, put it into a 600 gas magnetic field and clearly, the positrons were bending in the wrong direction in a magnetic field, meaning that positive electrons were being created in my cloud chamber. Later, I built an atom smasher in hopes of getting a beam of antimatter. So antimatter has the opposite charge of ordinary matter. The antimatter that I photographed in high school had a positive charge. Electrons usually have a negative charge. So anti-electrons can circulate around anti-protons. And we did this at Cern, outside Geneva Switzerland, and also at Ferma Lab outside Chicago. In fact, if you read the novel, Angels and Demons, which was made into a movie starring Tom Hanks, the whole novel was based upon building an antimatter bomb that might be able to destroy the Vatican.
So if I had antimatter and, according to the novel, if I touch it with ordinary matter I would have complete annihilation, meaning that the efficiency of the bomb would be about 100 times greater than the efficiency of a hydrogen bomb. A hydrogen bomb is only about one percent efficient; antimatter bomb would be 100% efficient. So anti-people are also possible. Anti-planets, anti-galaxies are also possible. But the danger is that if the two touch each other. And they will annihilate into a burst of energy.
However, we've looked for antimatter in the universe. And we've looked everywhere for antimatter, and we see very little antimatter in the galaxy. There is a fountain of antimatter coming out from the center of the Milky Way galaxy. In the direction of the constellation Sagittarius; however, it's very small. And it leaves the mystery, why are we made out of matter and not antimatter? Why don't we meet anti-people out there? That's a big cosmological question. The Leading Theory Is, at the Beginning of the Universe, at the Big Bang, there were almost equal amounts of matter and antimatter. The two annihilated in the instant of the Big Bang and we are the leftovers. So everything you see around us today we believe is a leftover from the titanic annihilation of matter and antimatter at the beginning of the universe itself.

Not possible because our universe has a allot of matter. As soon as it touches with any matter then it transforms into instant 100% energy boom. Physics doesn't say it's impossible but truly how possible is it that anti matter survived from the big bang enough to make a habitable solar system with life dodging any normal matter. Not to mention anti matter has electrons and neutrons in the middle with protons where electrons should be. Meaning their physics would be a lot different and they would have different elements than us Or at least that's what I think.

Knee dragon, I can appreciate your speculation. I too have contemplated a more productive and/or conventional use. I then found a documentary surrounding the studies of scientists who have been working on such a use. What you ask? Space exploration, deep space as a matter of fact. My colliding the positrons with the electrons gamma rays are produced which will slowly propel a ship at an exponential rate until it reaches light speed. From here we would theoretically be able to reach the outer reaches of the galaxy instantaneously. The only barrier, however, is the storage of positrons and being able to trigger the "annihilation" at the desired time. I sure hope that they can find a way to make this work because it would be an amazing discovery indeed.

It depends on the number of particles annihilating. An electron and a positron have a mass of 9.11*10^-31 kg each, giving a total mass of 1.82*10^-30 kg. If one electron annihilated with one positron, the amount of energy released is given by ΔE = Δm *c^2. So the energy released from one annihilation is 1.82*10^-30*(3*10^8)^2 = 1.64*10^-13J. To put this into context, the average human BMR is around 100 W (joules per second). To power a human, you would need 6*10^14 annihilations per second.

According to one idea I read about, anti-matter might have anti-gravitational properties when interacting with ordinary matter (but behave like matter when interacting with itself), therefore explaining why there is little anti-matter in this observable universe. This anti-gravitational property might also explain what Dark Matter and Dark Energy really are: byproducts of this repulsive curvature. Now we just need a visible lump of anti-matter and see how it interacts...

@deyomash It's been a while since I've read up on this, but I think the theory is that the universe started with *almost* equal matter and antimatter, (10 billion to 10 billion and 1 ratio IIRC). Now that most of it has annihilated each other, the ratio between matter and antimatter is much more significant. Of course, we're still trying to figure out why there was that slight difference in matter and antimatter in the first place.

@Nataani2376 11 жыл бұрын

No, because when anti matter and matter come in contact with each other they annihalate (the process by which all of their mass is converted to energy). So any anti matter which could be contained in a person would be annihalated almost instantaneously by the normal matter which makes up the person.

Wow, indeed an interesting question! And is seems dark matter interacts with matter only through gravity, so, maybe, the dark matter holding some galaxies could be mostly "Anti-Dark Matter"? It could be ok to have matter and anti-dark matter together without causing an explosion. As we can't differentiate anti-dark matter from dark matter, This could be the possible explanation for the asymmetry. The anti matter just got to another vibration in the string theory.

what i think is that antimatter lies on the other side of the space and time fabric, according to the big bang theory there was no space and time in the very early universe(before planks time which is 10*-41 sec).now space and time might be like a mattress which if u put wight on it bends that is how gravity wells are formed by planet, stars galaxies etc. some how antimatter and matter cant pass through the spacetime fabric everywhere but only in the black holes. so blackholes are nothing but a hole through the spacetime fabric through which matter amd antimatter combines and produce a lot of energy that we observe. that is where everything end ,all the matter, light photons even time. moreover the gravity wells formed by matter might simply be the atraction between the same amount of matter and antimatter on each side of the 'mattress'.

right but as the second part of my question/statement said, I am thinking that if there are antiparticles then they will have opposite properties. Specifically, a repulsion due to gravity (instead of an attraction) since gravity effects objects with mass and so the antiparticles would be seperated from particles. What I am suggesting is that their is an anti-universe isolated from our universe and that during the big bang the two types of particles were split by gravity.

@MsSkateboardP Dark matter is now thought to be present everywhere around us, and to be of a kind that would not (easily) interact with out kind of matter. Like neutrinos they would just pass through us, so an asteroid would not be blocked by dark matter. Secondly, the energy produced by a single annihilation of a positron/electron is still not very high (equal to their rest masses). The rest mass of an electron is 8.1*10^-14 J according to Wikipedia.

I didn't hear him mention, but if he was making positrons to the point where he can see them, shouldn't that have been enough that they would react with either stray particles in the cloud chamber or react with whatever other particles might be in the chamber after he shuts it down and cause annihilation on a rather large scale?

@Willgtl 11 жыл бұрын

If a particle and it's opposite antiparticle collide, you get annihilation. If you came into contact with the antiparticle version of yourself, every particle in both bodies is converted into energy (Mass-energy equivalence) at 100% efficiency since matter cannot be created or destroyed. It's the same concept of how particle-antiparticle collisions work in colliders to "create" exotic particles. They're not really created, instead the force carriers convert into other particles.

@Cruiser000x It's not hard to do. All you need is a glass chamber of low air pressure and high humidity. When you introduce your particles, push a plunger and increase the air pressure. The water will condense and the particles zipping around inside make vapor trails. Photograph these trails and you can study them. Bonus points for influencing your charged particles with a magnetic field. This is how antimatter was discovered in 1932, via cosmic gamma rays knocking electrons around

I am not sure about presence of antimatter as a student of physics I believe that it's only a theory however trying to prove it can lead us to more questions than answers. As far as anything that is considered anti anything it exists in an intellectual form for instance if one is social versus ant social etc. Things either are or they are not in terms of their physical form. Any or all the matter is formed into different things as it's being used it take different forms solids liquid gases etc. So can something be destroyed or completely make dissapeared "I don't think so"

@mxviii 11 жыл бұрын

Not necessarily, Anti Matter is incredibly volatile, it does not require the same quantity of Matter to annihilate. So a huge quantity of anitmatter might only come in contact with a very miniscule quantity of matter, and the whole thing would annihilate. The instant conversion of matter into energy that results pushes everything away in all directions like an explosion. Its very easy to see how matter would eventually outnumber anti-matter.

@Mtc529 It's a really difficult question to answer. It's sort of a pardaox, think about it, if anti-matter was 'the leftovers' it would be natural to us and the matter that makes up us in the state we are currently in we would call anti-matter and vice-versa. so no matter who won (matter or anti-matter) the opposite would always be the one that should not be. so it really doesn't matter what remained, just be thankful that you are you!! :D

This is called "mindfulness meditation". When you practice mindfulness (or awareness), you see "things" much more deeply. Thinking is not awareness, thinking is a "thing" and awareness is "no-thing". You cannot understand nothing with "some-thing". It like if youre stuck on the bottom of the river, ..

What I don't understand is why the scientists don't put the antimatter into a container sealed tight enough so matter can't get to it! That way they could keep it around long enough to use it. Sometimes it's the simplest ideas that get overlooked...

the theory is space and time did not exist prior to the big bang, which was an infinitesimally small singularity point of extreme mass and gravity. If you were at the boundary of the universe and try to reach out it feels like a force field is blocking it, b/c space doesn't exist, just like if you were traveling at the speed of light you can not move your hand forward because your hand would be traveling faster than light.

And furthermore, Doppler was right. "Inertia is caused by the gravitational attraction of masses around the earth", he said. But he couldn't explain why the value of intertia was always the same when the masses around the planet are not uniformly distributed. Now we know that dark matter is indeed distributed that way. The old austrian was right again. Chapeau!

Interesting, according to string theory though the fusion or division of universes creates new universes, would this mean that an antiuniverse and a normal universe collided and created what we have now in our universe?

I like to think of it as balancing a semi-truck on an impossibly strong needle. Eventually one half of the truck will lose balance with the other half and it will avalanche to one side.
