What else can I help you with?
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".
Why matter overcome antimatter?
That is one of the unsolved problems in cosmology. There seems to be a slight difference between matter and antimatter, that is, the symmetry between matter and antimatter is not perfect. But the details of baryogenesis are not known yet.
What does antimatter look like and how does it differ from regular matter?
Antimatter is a type of matter that is the opposite of regular matter, with particles that have opposite charges. When antimatter comes into contact with regular matter, they annihilate each other, releasing energy in the form of gamma rays. Antimatter does not have a specific appearance, as it is not visible to the naked eye.
What happens during a matter-antimatter reaction?
During a matter-antimatter reaction, particles of matter and antimatter collide and annihilate each other, releasing a large amount of energy in the form of gamma rays and other particles.
Why the antimatter disappear in universe?
When antimatter comes into contact with matter, they annihilate each other.
Does antimatter possess negative mass?
No, antimatter does not possess negative mass. Antimatter has the same mass as regular matter, but opposite charge.
If 1gram body of antimatter meets a 10gram body of matter which survives?
Initially the 9g of remaining matter would survive. Each particle of antimatter can only annihilate with one other particle of antimatter. At this point the 1g of antimatter would cause an explosion equivalent to that of 200000 pounds of TNT. Causing both groups of matter and antimatter to be obliterated.
Will antimatter start a black hole?
No, Antimatter while annihilate our matter, meaning that it will completely convert our matter to light and heat, however antimatter is highly theoretical, and the LHC probably will not create any.
What is the theory of creation of matter and antimatter from nothing?
You are giving the definition for the Big Bang Theory.
Is dark matter related to antimatter in any way?
No, dark matter is entirely different from antimatter. For one, we know a lot about antimatter and have been able to do experiments with it and actually utilize it in some nuclear reactions. Dark matter is a theory to help understand why the universe does not behaive the way we believed it should. Galaxies are showing that they do not have enough mass to have the gravitational effects that they do, so there must be matter somewhere, this is labeled as dark matter.
How does the concept of antimatter affect our understanding of time?
The concept of antimatter affects our understanding of time by challenging the symmetry between matter and antimatter. Antimatter particles have properties that are opposite to those of their corresponding matter particles, leading to questions about why there is more matter than antimatter in the universe. This imbalance could potentially impact our understanding of the fundamental laws of physics, including those related to time.
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.
