hello /sci/ what are your thoughts on antimatter and protonium

It's sort of like matter's evil twin
Because except for charge and handedness and spin
they're the same for a particle and it's anti-self

I do find the asymmetry between matter and anti-matter interesting, and I think that when we eventually find a way to contain and transport it safely, it may make an excellent fuel.

I don't know, what did you want me to say?

you watch too much angels and demons... it takes more energy to make anti matter than it can give.. it isnt a good fuel source

it's beautiful

No, I don't even know what that is...from context, I assume some sort of TV show.

In any case, You're misinterpreting what I mean by fuel. I fully accept that we can't harvest antirocks out of the earth an burn them. What I'm talking about is taking some other sort of energy (solar, nuclear, whatever), and converting it into antimatter. The reason for this is that a small amount of antimatter has a ridiculous energy density, so in cases where the weight of the fuel is important (like rocket launches), it will make an excellent fuel, no matter where the energy to make it came from in the first place.

Well, a tiny amount of antimatter produces a ridiculous high amount of energy but you need a ridiculous high amount of energi to produce a tiny amount of antimatter. Now remember that there is no 100% efficient energy conversion(most of the energy used to produce antimatter will be lost and most of the energy got from antimatter will be lost too) and that store something that reacts with any matter need constant energy use this isn't a great thing to use as fuel.

TL;DR too expensive and, instable and too hard to store.

I originally thought antimatter had negative mass. Unfortunately most physicists contend that while everything else is opposite, it has positive mass. So someone can't build an anti-matter bomb and have say, the Empire State Building vanish, which would be cool and also scary.

Just to throw out some troll bait, certain theories contain tachyons, which have imaginary mass. Among the pathologies they create is violation of causality.

With regards to negative mass... I'm not actually sure what prohibits them.

hay guys are gravitons antimatter?

I believe antimatter will reach a maximum of usefullness in the next 10,000 to 100,000 years as the primary source of a densely high energy battery for use in solar system space, ground facilities and local stellar space.
Once and if we master the ability to utilize our solar system resources more fully and are able to reach and control a few local star systems, humans should be able to develop large scale nuclear fusion energy generating systems that will be able to create antimatter particles. Most of the advanced and difficult technology needed to effectively marshall large scale nuclear fusion generation is directly related to the difficult technological challenges involving the storing, transport use, and safety/waste of antimatter/matter particle use. From the high energy pulse lasers,superconducting high tesla magnetic bottles,high performance sensors and computers all of this tech plus large particle accelerator technology could be used to generate these materials.
Just as the Romans innovated and utilized the technological potential of their "culture" in order to create access to clean and plentiful water for all of their citizens; we have harnessed our civilizations talents and freedoms to facilitate universal access to: gasoline, electricity ,water and natural gas.
I believe in the future people will have access to very high energy fuel cells, chemical and elemental creation and customized personal manufacture. As well, the supplemental solar system culture will demand access to very high energy needs that cannot be efficiently met by specialized chemical creation and nuclear fission exploitation.
However efficiently it is done, large amounts of antimatter will be created to facilitate our burgeoning galactic spiral-arm culture. When a means of producing a viable way to CREATE and/or
DESTROY energy and matter and create an "energy" source that is absence of the burden of material and gravity distorion, only then will antimatter/matter batteries be relegated to history.
Its amazing to me how the discovery of the most
technologies that should affect life seem to constitute a subscript in our culture; from nuclear fission, fusion, genetics, semiconductor,polymer chemistry and particle physics this 20th and 21st century scientific/technological commercial culture has founded a legacy that will be felt for literally tens of millions of years.
respones appreciated...

Firstly whats known: anti-matter does not mean anti mass or anti-energy it refers to particles with opposite charge to normal particles. An anti-proton is a particle made up with three normal quarks connected by normal gluons to make up a particle with opposite electrical charge. Similiarly an anti-electron is a type of particle(lepton) with a positive charge.
Conventional cosmology contends that the background radiation, and galactic expansion which indicates a big bang that created our section of the cosmos would have yielded near equal amounts of particles and anti-particles
that would destroy each other, with that small fraction that left constituting our universe. This means what we naively perceive as real and significant is absurdly false, if this theorey is true. We already can observe that 75 percent of the mass/energy of the observable universe is dark energy; whats left of that 25 percent is 23 percent dark matter; of the galaxies dust and intergalactic medium thats left only 4.6 percent constitutes ordinary mass/energy. Our solar system represents only one part of 100 billion solar systems in a cosmos containing 100 billion or more galaxies; each galaxy separated by a factor of a million compared to the separtion of solar systems10 to 100 light years ;where a light year(6 trillion miles) constitutes a factor of 5 to the 15th of a person;and the size of an atomic system at 10 to the minus 10 metres constitutes a factor of 10 to the 10th from a person to an atom; where the factor of size of an atomic nucleus to an atomic nucleus is 10 to the 5. Ignoring the scale of interaction between quarks and gluons in the atomic nucleus (which is significant), The scale from atomic nucleus to human; 10 to minus 15 to 1 and from human to the observable universe is 1 to 2.4 to the exponent 28 yielding a factor of 2.28 to the exponent 42 with regard to an atomic nucleus and the observable universe.
The point is if you estimate that the normal matter that constitutes the universe makes up only one trillionth or quadrillionth of the original mix of particles that was destroyed then that factor of insignificance( or Cosmological significance) becomes like 2.28 * 10^55 or 60. When combined with the dark/matter energy balance it becomes a maximum of 2.28 *10^63
This number is so preposterous that just as copernicus couldnt believe that the suns and planets circled the earth in a complex ptolemic clockworks around the earth, I believe that this number only represents our current level of ignorance. The significance of dark/matter and energy and the origin of matter will eventually be truly know.

Antiproton is made of antiquarks.
