Best Answer

An antihydrogen is an atom of the antimatter equivalent of hydrogen, or the antimatter equivalent of hydrogen as a collective.

Which element has negative charged proton?

All protons have a positive charge. The antimatter equivelant to the proton, the antiproton, has a negative charge. Every element of matter (hydrogen, helium, etc.) has an equivalent antimatter element (antihydrogen, antihelium, etc.) and just as every element of matter has a proton in its the nucleus (which, again, is positively charged), every corresponding anti-element has an anti-proton in its nucleus (which is negatively charged). There are also theoretical "hybrid" elements (called exotic elements of atoms) consisting of both matter an antimatter components, such as a proton and antiproton orbitting each other (this is called Protonium).


Can you use liquid nitrogen to freeze antimatter?

Most antimatter exists as subatomic particles produced either in radioactive decay or large particle accelerators. No significant quantities have been made and the only antimatter atoms ever produced have been antihydrogen. Any antimatter that came in contact with liquid nitrogen would annihilate both itself and part of a nitrogen atom, releasing energy that would heat the remaining liquid nitrogen. If you could somehow produce a quantity of antimatter equal the the amount of liquid nitrogen, when they came in contact instead of cooling the antimatter there would be total annihilation of both materials resulting in an explosion on the order of teratons of TNT equivalent as the temperature of the products jumped to hundreds of millions of degrees kelvin to billions of degrees kelvin!!!!!

What is anti hydrogen?

Antihydrogen is the antimatter equivalent of hydrogen. An antihydrogen atom consists of an antielectron (also called a positron) and an antiproton.

Who first synthesized antimatter?

The first known antihydrogen atom was synthesized in 1995 at the CERN laboratory in Geneva. However, antimatter itself is produced constantly in the natural environment.


If you mix anti-oxygen and anti-hydrogen do you get anti-water?

"one can mix antihydrogen and antioxygen in definite proportions and then combine them chemically (the consequences of this explosion in the antiworld may be as lamentable as in the ordinary one) and get anti-H2O, i.e. a transparent liquid substance boiling at 100 °C and being a good refresher (naturally for antipeople), in short, one that resembles in everything its counterpart, water. Similarly, all kinds of antimatter reproducing all varieties of the matter surrounding us may be combined from elementary antiparticles."

What is the most expensive material on earth?

AeroGel, It cost About $300 billion per milligram. Just a comment here: That is debatable. The very chemical composition of AeroGel makes it about 99% air. That means its actual mass at that weight (1 milligram) is considerable. If you are going for "most expensive material on earth" by actual amount/size/mass, it's probably antimatter. Again, debatable. Oh, almost forgot: the last time I did any research on this, antimatter (especially antiatoms like antihydrogen), were at $1,750 trillion US Dollars (USD) per ounce.

AnswerThere is no most expensive thing on Earth. Some things are so expensive no-one on Earth could buy them. Not even all the money on earth could buy them. They are priceless, like the Earth is impossible. People want to be it but they can't

What is the importance of antihydrogen?

Antimatter is the opposite of matter and so when the two come in contact with each other, they become nothing but neutral energy. The idea that it is possible to create antiatoms is astounding simply because matter is everywhere. On top of this, it takes a lot of energy. so to create antimatter alone is rather difficult. It's also a difficult thing to sustain for more than a few seconds, if even that long, because it's always surrounded by matter. In other words... The fact that they were able to create it is simply incredible. Further more, if we look into the theories there are about antimatter, we can see some amazing things that could end up being true. One of these is the idea that the big bang began with a neutral Higgs particle which somehow became imbalanced. suddenly, this imbalance created a supermassive amount of energy. Because the Higgs particle is so heavy, much antimatter and matter were expelled. Because there was an imbalance, the amount was not perfectly equal and so it wasn't all cancelled out. The idea is that there was more matter. The matter that was equal to the antimatter was cancelled out by the antimatter and the rest of it became what we see as today's universe. Due to the fact that it was thrown outward so rapidly however, not all the matter and antimatter touched. Which meas that some anti matter flew way out to the far reaches of the universe...(Which was, scientifically speaking, much much smaller when if first started. Then it got really big really slowly... that is the meaning of big bang... slow expansion) So there could be regions of our universe bigger than our galaxy that are completely composed of dark matter. It really isn't important, but one day a million years from now, when people can travel space that far out... then it may just matter...


Gamma rays are the most energetic form of electromagnetic waves known. Would not a gamma ray laser be the most powerful known weapon that could be built with our present understanding of physics?

Would a gamma ray laser be the most powerful known weapon that could be built with our present understanding of physics? Possibly. How about an x-ray laser? X-rays are only a little less energetic than gamma rays. Would that work? And to get the big energy pulse, what would be used? How about a nuclear blast? Is that okay? This issue is an old one. It was run up the flagpole under the Strategic Defense Initiative. Remember Star Wars? The 80's saw a lot of time and money dumped into research on the nuclear pumped x-ray laser. The many technical difficulties coupled with the fact that a nuc would have to be lit off to fire the thing spelled its doom. We just don't have the technology to pull this one off. A link is provided to an old NY Times article from the early 90's. It's the obit for the nuclear pumped x-ray laser and it provides corroboration for this answer. Dark Energy would be the most powerful weapon or laser made. Its continuence building of energy would be like a rail machine gun. When hydrogen is hit by static charge or lightning (from the big bang) The negative side or antihydrogen collects and starts to fuse together. This builds to a point and starts what I have named a Mantle short for Relativistic Perturbation Mantle. In this high energy physics display ... energy to Helium blow off to the moon too Carbon sealing in the energy too Oxygen in massive amounts to LOx slowing the fusion down to Carbon again sealing this into a 12 foot 2d Disc. Since the energy has no place to go it starts the conversion of the first ring to high energy photons. This is now dark Matter creating Dark Energy or our Aether world. Compton scattering, duel split screen quantum mechanics all come from Mantles dark energy.


What will happen if antimatter and matter have the same number in the universe?

Probably not. The universe has been here a long, long time. There is a lot of matter around, though it's concentrated in galaxies and the like. Even as gravity concentrated the matter into these "islands of stars" it would have also pulled on antimatter. There would have been a lot of annihilation. Not much antimatter would have been left. But there is more mass in the universe than can be accounted for by what we can see. It's that "dark matter" thing. There is a greater mass of "stuff" we can't see than stuff we can. Calculations based on the effects of gravity show us this. Something is pulling on stuff, exerting a large gravimetric pull, but we can't see it. Gravity is "created" by mass, and there's a lot "missing" out in the galaxy. There isn't any argument about the "missing matter" in the universe, only where it's hiding. And the hidden matter might be antimatter. It is improbable for the reasons stated above, but the probability that there is a bunch around somewhere isn't zero.
