Do we have anti-matter?.... I mean, is it something we can contain?... I read that matter and anti-matter will "Self cancel", I dunno about explode. However, that was theoretical. Its like having questions about Zombies... I always say bring me a real life zombie and we can talk.... Bring me real life anti-matter, we can experiment.... has anyone ever created or contained anti-matter, or even observed it, and if so, what happened?..... My own theory, I can theorise all you want, but until its in front of me, I cant give you exacts?.... Anti-hydrogen atoms have been produced and observed at CERN: en.wikipedia.org/wiki/Antihydrogen#ProductionWhat has not been observed is how anti-matter interacts gravitationally with either matter or other anti-matter. The consensus is that it should behave the same as normal matter but there is a strong desire to confirm that experimentally. Matter/anti-matter 'self cancels' by annihilation, which means total conversion into energy. Since the detonation of a nuclear device involves conversion of only a small percentage of mass into energy, I'd say total conversion would be considered an explosion. |

The universe is quite a large place, with lots of space in between for stuff to exist in, and I figure that it is quite possible that just in this region of the universe, regular matter dominates.
From a distance, it is impossible to determine the difference between regular matter and anti-matter and it is within the realm of possibility that some of the galaxies we can make out at the limit of our ability to see them could be made entirely of antimatter.
For that matter the galaxy "three over and just to the right " of ours could also be antimatter. We just can't tell from here.
I don't claim to be any kind of astronomer or an astrophysicist, but this theory sounds at least plausible to me.
At least it doesn't postulate the (to me) iffy theory that the big bang favored the creation of one type of matter over the other.

I remember an explanation of space....
This is a quote along the lines of what he actually said, I dont remember exact words, but this is "Close enough"
Imagine a warehouse, make it bigger, no really THAT much bigger..?...
LOTS of empty space right?....
Now go outside....
There is many more warehouses.....
Now take them all away and leave nothing.
Can you handle that yet?...
There is plenty of nothing in which you can create as many spaces to create as many warehouses as you could possibly imagine....
And when you have finished, someone else will take over and make more.....
But those are only imaginary warehouses.
If you could take your imagination of how big space REALLY is, you are thinking about the size of a small asteroid in reality to what science thinks it is, and in turn, as they find more, they are thinking only the size of a large universe.... and we are now thinking there is more than one of those as well.
(This was back in the 80's-90's, we now know that there MUST be other universes)
That was a very YOUNG me listening to a Prof who had a way with words that made thinking easier.....
It still creates a small anomaly that I cant actually handle the TRUE size of Space, but, in me knowing that, I am close to understanding Infinity...
To Understand infinity, you first have to realise you will never understand the full infinity.
In Infinity, it is quite possible that there exists a plant that grows leaves with a strange pattern on them that resembles the exact size dimension and weight of a Dollar Bill.
Its just its soo far away in space, we will never see it?....
Things happen in space that we will never understand, and whats more, they just happened, and we do not have the power to witness them anyway?...
We know less about what we dont know than we can even hold in our human mind anyway about what we do know we dont know, ANYTHING is possible, and in saying that, I know I am starting to wander a bit on and off topic.
I cant really understand things I dont witness myself, because I always have questions.
But, and being self critical I know, a Fool may ask more questions than a wise man may answer?....
I DO live in VERY interesting times.... I enjoy the challenge.

I spent the last couple of nights watching professor Brian Cox lecturing young GCSE students about the universe on Utube. Smart man, if he is typical of scientists in the UK then I can see a marked difference between them and US scientist where religion is concerned if the previous forum is atypical.
With all due respect to SD we do not know that other universes exist, we know there is a possibility that they exist but we do not know it as fact. Apparently we do know that quantum mechanics does predict that there is 1 followed by 41 zeros not enough matter in the Universe as described by Marcus Chown, confirmed by Lawrence Krauss in his lecture a Universe from nothing. Basically they did not like talking about it because it was "kinda embarrassing" that there best theory predicted such a large error, up till they discovered dark energy which has not been quantified,,,,, well sorry not seen yet. Possibly a bolt on to make the theory work
Now I find all this stuff fascinating, Richard Feinman (sp?) is quoted (roughly by me sorry) as saying "you make a guess, devise the outcomes of that guess and test it by experiment, if the results do not match" you got it wrong.
What is known about matter antimatter reactions is the energy is converted back to different particles of matter.
