What is an antihydrogen?
An antihydrogen is an atom of the antimatter equivalent of hydrogen, or the antimatter equivalent of hydrogen as a collective.
What is anti hydrogen?
Antihydrogen is a form of antimatter consisting of an antiproton and a positron (antielectron). When antihydrogen comes into contact with ordinary matter, they annihilate each other, releasing energy in the form of gamma rays. Scientists study antihydrogen to better understand the nature of antimatter and its interactions with ordinary matter.
How much does antihydrogen cost?
62.5 trillion dollar. Good luck getting some.
Who first synthesized antimatter?
The first synthesis of antimatter was achieved by Carl D. Anderson in 1932 when he discovered the positron, which is the antimatter counterpart to the electron. Anderson's discovery provided experimental evidence for the existence of antimatter.
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.
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!!!!!
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).
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...
How are cermaics made and how are they made?
Made
What is the difference between made of and made from?
"Made of" and "Made from" can mean the same thing. "That can is made from aluminum." "That can is made of aluminum." However, they can't be used the same in every situation. You can say: "That house is made of wood and made from workers." But you can't say: "That house is made of workers and made from wood."
Where was YouTube made?
It was made it was made on the Internet
