4.3% of the universe (~45 Billion Light year diameter) is Planets, Gases and Such. Dark Matter (WMP, or Weakly Interacting Mass Particle) is invisible. If my math is correct, (and i did it on a hitachi supercomputer) the universe should weigh around... 790 centillion centillion centillion centillion centillion centillion centillion centillion centillion centillion centillion centillion centillion centillion centillion centillion centillion centillion Tonnes, to the 947,304,691,120,161,109,425e+4964546546516548897984351th Power! I Guess About 74 followed by trllions of trillions of trillions of digits, pounds thats heavy

∙ 12y agoAs far as we can tell, virtually none. Only about 4 percent of it is even "matter" in the sense we usually mean by "matter".

Why do you live in a universe that is made of matter rather than antimatter?
This is not currently known. There does exist some asymmetry between matter and antimatter - meaning that they are not exact opposites in all aspects - but this asymmetry is not enough to explain why matter exists.
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.
What is the destiny of the sun?
Being an astrologer I know that heavenly bodies have their horoscopes too. All the planets, souls , matter and antimatter have one soul. Sun will burn to give light to the universe, where darkness is eternal till it extinguishes. Anything with a limit has a destiny and a purpose.
Would the world be different if it was made of antimatter?
Yes, it would be different. Antimatter is in a way the opposite of matter, but it is not the exact opposite. There are slight differences - and that is somehow the reason why we have significant amounts of matter, and not of antimatter, in the first place - though the exact details are not well-known yet (you can find out more details in the Wikipedia article on "Baryogenesis").
What is the name of all of space and everything in it?
Universe
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 there an antimatter universe?
Scientists admit that there may be as many as 27 'parallel universes' to our own. It is quite possible that there is not only an antimatter universe, but parallel universes to it.
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.
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
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.
What is the most explosive thing in the universe?
A Quasar, solar flares, or galaxies exploding
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.
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...
