# Matter/antimatter collisions is now what bugs me

First post here so sorry if I got it in the wrong spot. I'd like to say though I am very exited to have found this site. I see some sleepless nights in my very near future

Matter/antimatter collisions, appear to me, to violate the Law of conservation of matter and energy. I suspect once we understand more about multidimensional physics we shall find the law to hold true. But hey, like my name says im the amatuer, I also suspect there could be more plausable explantion out there and I just haven't found it.

I turmoiled over the Big Bang for a long time until I found "Inflation" ; which summarily removed my problem with the theory. Matter/antimatter collisions is now what bugs me (partial geek here I guess).

Re: Antimatter

reading the post, my question is why does the collision not prove the law false.

Re: Antimatter

How?

The amount of energy released from the collision of matter and anitmatter is determined by E=mc2, i.e. complete conversion of matter to energy.

Re: Antimatter

What makes you think that such collisions would violate conservation of energy? (There's no such law as conservation of 'matter'.)

Re: Antimatter

First thanks for the reply! I guess I'm missing the bassics then. My understanding when Matter/antimatter collide, a complete annihilation occurs. Nothing left. No matter, no energy. Are you telling me the matter is gone but energy is released into the universe?

Re: Antimatter

Yes, that's one possibility. When the particles annihilate, energy is released as photons. The total energy (including rest energy of mass) is always conserved.

Re: Antimatter

Well thanks. I was thinking the energy was gone as well.

Thanks for helping a curious amatuer, sorry if I wasted your time.
