Matter and antimatter
For every type of matter particle we've found, there also exists a corresponding antimatterparticle, or antiparticle.

Antiparticles look and behave just like their corresponding matter particles, except they have opposite charges. For instance, a proton is electrically positive whereas an antiproton is electrically negative. Gravity affects matter and antimatter the same way because gravity is not a charged property and a matter particle has the same mass as its antiparticle.

When a matter particle and antimatter particle meet, they annihilate into pure energy!

So it's not about charge but spin .

What would a pure positive or pure negative Universe be like ?

if you are speaking of a universe made of anti matter instead of matter, then I have answered that.
If we were all made of anti matter along with everything else, we would be calling anti matter, matter, and matter, anti matter.

But when matter and antimatter come into contact, they annihilate – disappearing in a flash of energy. The big bang should have created equal amounts of matter and antimatter. So why is there far more matter than antimatter in the universe?

And as I said earlier, that part of the BB and evolution of the universe, remains as an unsolved problem.

No, its about opposite charges as both my links suggest.

But it doesn't make sense pad .

There is something else going on if that's the case . Like charges repel ; opposite charges attract.

Since matter and anti-matter exist . The only way to create pure energy is to force them to come in contact with each other.

Nature does not force them to come together .

Sorry, if it doesn't make sense to you than you have a problem.
opposite charges attract.
Gravity is also in play and an attractive force.
Can't make it any simpler than that.

The video is useless.

Gravity is the weaker of all forces .

It has nothing to do with matter and anti-matter .

Nature does not force matter and anti-matter together.

You have one thing right anyway :rolleyes:...gravity is the weakest of the four forces.
But to say it has nothing to do with matter and/or anti matter is totally illogical and against all our known laws of physics.
But perhaps you may have some hidden knowledge or link to support such a nonsensical statement?:D
 
And of course the video simply explains how the job of physicists is to explain what happens, and not necessarilly the deep philosophical reasoning as to why.

The apparent asymmetry of matter and anti matter in the visible universe is one of the greatest unsolved problems in physics.
[a point I already made to you]

However, when matter and antimatter meet, they completely annihilate each other in a brilliant flash of light produced by extremely high-energy gamma photons. This explosive annihilation mirrors the huge energy required to produce the matter-antimatter pairs in the first place.
[the second point]

For example, the high-energy cosmic rays which regularly impact the Earth's atmosphere produce minute quantities of anti matter in the resulting particle jets, which are immediately annihilated by contact with nearby matter. The tiny quantities of anti matter which scientists have managed to create in the laboratory have always been accompanied by an equal quantity of normal matter, and the two tend to cancel each other out almost immediately.
[the third point showing the experimental results totally supporting what I have been telling you]

Now we're getting some where .

What are the properties of these particle jets ?

:) You're funny.
Exactly as I have been telling you since you queried. :rolleyes:
So you now agree that they annihilate?
On your other question, google is your friend.
 
from the link:
" The cosmic microwave background radiation which pervades the universe today represents the remains of theenergy produced by this wholesale annihilation of the matched particle-antiparticle pairs. But a small imbalance remained, in the form of an excess of matter, of the order of one extra matter particle per billion matter-antimatter particle pairs. It has been calculated that this apparently tiny imbalance in the early universe would be sufficient to make up the amount of matter presently observable in theuniverse".
 
The link concludes with a couple of possible solutions......

Google is basic . Primitive or simple information as is Wikipedia. Hardly the places for in depth explanations.

Then you havn't got an in depth explanation, have you? :)
But I'm sure if you try hard enough, and if you really want an answer, you will most certainly find an in depth explanation as most always do.
 
First of all where does the emptyness of space came from and where doest the negative matter and possitive matter came from? they cant be created out of no where everything has an origin if u think about who comes first the egg or the chicken u would really be confused but my answers is an organism mutated in a egg and become the chicken but that egg didnt come from the chicken it come from another source it just mutated into a chicken and same as the one where it mutated from for example a type of bird who comes first bird or egg until we reach that point the very origin they say everything has an origin so what is the origin of the negative and possitive matter u cant say it made itself from +1 -1 where does the +1 and the -1 came from? what is their origin and the emptyness of space?
 
If u think about a origin with no origin its a God not on the books but a God who made this matter, i have 3 self opinion the matter have some origin and created itself, theres a God who made the emptyness and mater, or were living in a simulation and we have a real world outside of this universe. but we will never know the answer were like characters living inside a 2d book. even how much effort we do to see the world outside the book its just not possible we live in a 2d world we will never understand or see the 3d world
