what are the by products of this reaction and if the universe is expanding into anti matter why are there no visible results as surely it is a massive reaction.

try http://en.wikipedia.org/wiki/Feynman_diagram as this is a picturial explanation of what happens when particals collide.
Newton, nope sorry after his time you're well into quatum partical physics here.
I believe the antimater theory you refer to may be that eventually an ever expanding universe may end up as purely light and eventually this will fade leaving, nothing at all...

When matter and antimatter meet they annihilate each other and create a huge burst of energy. This reaction doesn't really have much to do with Newton's laws; Einstein (and quantum mechanics) would be more applicable. Matter and energy are basically different aspects of the same thing at the subatomic level, and they can change from one form to another according to the equation E=mc2.
The universe is not expanding into antimatter, it's just expanding into a bigger universe. The fabric of space itself is "stretching" and carrying all the galaxies along with it -- that's why the distance between them is increasing. The vast majority of the matter in our universe is regular matter, but it's not being converted into antimatter.
Note: antimatter is not theoretical, it HAS been created in the lab.

The annihilation of matter and antimatter is more of a change in quantum state---like an electron emitting a photon when it changes state within an atom. It's not a classical process. Our visible Universe (and the immediately surrounding material) is not expanding or colliding with antimatter to any significant degree. In the early Big Bang, there were approximately equal amounts of matter and antimatter, and almost all annihilated, leaving the small amount of matter that remains in the Universe.

Anti-matter is a theoretical entity.
If you place one mole (theoreticaly) of antimatter together with one mole of matter, the net result is equivalent to:
minus 1 added to plus one = zero.
There was never a time when astronomers stated that the Universe is expanding into "anti-matter." What they have stated is that objects within the Universe are moving apart. Some of the objects are moving at astounding speeds as they do so. Space is not expanding. The objects are all moving within Space. And, so far, there have not been any dimensions proposed for space other than possibly "infinite."

Matter and anti matter each have mass, therefore there is gravity involved. Particles of matter and antimatter do appear and they destroy each other in a burst of energy called a gamma ray, which is pure energy. The universe is not expanding into anti matter, this is nonsense.

It was not Newton's law. He did know about anti-matter.
Anti particles that meet bits of regular matter release energy in the ratio described by Einstein. Add their mass in grams. Multiply by the speed of light squared in centimeters per second. The answer will be a very large number of ergs of energy. Don't stand too close. Mars might be "too close."

i dont think newtons law covers matter and antimatter. Their meeting causes the destruction of both and emits massive amounts of energy (no by products).
The universe is a result of the reaction. Apparently there was more matter than antimatter in the bigbang.

I don't think Newton was even aware of Antimatter theory...
The byproducts are pure energy - in photons and neutrinos. And, the universe isn't expanding into antimatter... it's just expanding.

it emits high energy photons
who the hell said the universe was expanding into anti matter?! that sounds a bit mental
