Why the antimatter disappear in universe?
When antimatter comes into contact with matter, they annihilate each other.
How come the universe is made of matter and not antimatter?
That is not currently known. There is a slight assymetry between matter and antimatter, but so far, it seems that this assymetry is not enough to explain why there is only matter, and hardly any antimatter, in the Universe. Without such an assymetry, there wouldn't be either matter or antimatter in the Universe - just radiation. For more information about what is known, and what isn't, check the Wikipedia article on "Baryon asymmetry".
Is the antimatter true?
There is antimatter (humans can create minute particles of it in accelerators). Whether or not there are large agglomerations of antimatter elsewhere in the universe is a matter of conjecture (guessing). But the chances are good (the universe is very big and there is lots of stuff out there.
What does condensed mean?
Or when you change ALL THE ANTIMATTER in the UNIVERSE into COOKIES.
What are two questions physicists have regarding antimatter?
1. Why is there more matter than antimatter in the Universe? Or: Why is there matter at all? (If there were the same amount of matter and antimatter, and it came into contact, it would quickly get destroyed. 2. If antimatter is so abundant, how come we've never come in contact with it or have been able to observe it?
Is there a large enough quantity of anti-matter to destroy the universe And where is it located?
It seems the Universe consists almost entirely out of matter - that is, there are no significant amounts of antimatter. Why there is more matter than antimatter is an unsolved problem.
Why is there not nearly as much antimatter than matter?
There are no definite answers with our current level of understanding of antimatter at this point but scientists believe that this is the result of an imbalance in the production of matter and antimatter particles in the early universe. Another explanation for this phenomenon is that Antimatter may exist in relatively large amounts in far away galaxies due to inflation in the primordial time of the universe
In our part of the universe antimatter is plentiful short-lived long-lived non existent?
AnswerIn our part of the universe, antimatter absolutely exists. We use it all the time for medical imaging. For instance, the "PET" in PET scan stands for Positron (an antimatter particle) Emission Tomography. However, it is not plentiful by any means and it is very short-lived...
Why is there far more matter than antimatter in the visible universe?
It may have to do with the way the universe was created. Certainly if there was a lot of antimatter created, much of it may well have come in contact with matter through the billions of years the universe has existed. That would have resulted in the conversion of that antimatter (along with a like amount of matter) into energy. There may not have been much antimatter around to begin with, too. But, since the amount of visible matter represents less matter than has been calculated to exist in the uinverse, it may be that there is a good bit of antimatter out there somewhere. Not likely, but possible.
Does the universe contain antimatter?
Yes, the universe does contain antimatter, which does naturally occur, although in quantities much smaller than matter. The very slight bias of physical law in our universe towards towards matter instead of antimatter is a subject of ongoing research; some calculations indicate that for every hundred billion particles of antimatter created from the energy of the Big Bang there were roughly a hundred billion "plus one" particles of matter - the balance eventually annihilating each other during collisions, resulting in a universe almost entirely of normal matter. Regions of space currently rich in antimatter have been searched for without success to date. Very tiny amounts of light antimatter particles do exist in cosmic rays; radioactive materials can spontaneously produce antimatter particles when they decay; and it can be produced in particle accelerators.
Can elements be made out of antimatter?
Yes. Antimatter is only a point of view concept : we can imagine any object made of what we call antimatter. According to his point of view, we would be made of antimatter. Moreover, a number of large areas of the universe, that doesn't have any contact with each other, may be made of antimatter. we wouldn't have any mean to know from where we are.
How could it B true that matter and antimatter at start of big bang With little amount of matter left in end winning B enough 2 make up all we see today?
It is not currently known why there is more matter than antimatter. Some assymetries (differences between matter and antimatter) have been found, but they are very slight, and it is not clear how this could have been enough to create the matter we see today.
