James: Thanks again for your kind explanation...here one source showing that the matter of our current universe is only 1 out of 2 billion of the matter and antimatter at the big bang: The laws of nature require that matter and antimatter be created in pairs. But within a millifraction of...

best wish to you...I wish I could help but I am not a physicist...my main interest in philosophy...good luck with your math model!

thanks for the response... I don't know why it is said that the matter in our whole universe is only 1 out of several billions of the matter and anitimatter at the beginning the big bang... However, if that is true, then our current whole universe is the small cluster in the sense of...

Thanks for the explanation...however, when you said that 'on largest scale, matter seems to be distributed in "strands" rather than isolated clusters' you were based upon the observation of matters...when there were some strands of matters and some strands of anitmatters (both of which was of...

how about a classic interpretation simply based upon the fluctuation theory of statistical physics as follows: 1) since it is said that the total mass of our current universe might be only one out of several billion of the total mass of the original matter and antimatter, it was indeed...

K^2: Thanks! Now I feel much clear about the issue!

thanks...I guess if it is the same as expected then we might explain the disappear of the antimatter with the same amount of the mass as this current universe by assuming that they might be in some black holes since within the black holes there is no difference between antimatter and matter...

niklaus: Thanks for the link...it seems that they are trying to confirm that the gravity between matter and antimatter would be the same as the gravity between matter and matter...let's wait and see what they would tell us... however, based upon the response in this thread I feel that...

Thanks all for the introduction of how dark energy is getting into the picture as well as the reminder of the difference between dark matter and dark energy... Somehow I still feel as space_buster said that those two theories are still two viable philosophies...because even though now I know...

mfb/K^2: Thanks for the response...as I understand that both of you are saying that no matter what are within the black hole, there is no longer any difference between antimatter or matter...anything pulled into a black hole become part of the mass and contribute to the charge and angular...

Phinds: Thanks a lot for the clear explanation! But to me, philosohically I would consider both dark energy and space self-expansion (i.e. space is something and that something itself stretch out without the need of any energy and it is meaningful not because the departures of the bodies...

Dave: Thanks for the clarification about "The annihilation and gamma ray bursting might begin while the bodies are still some distance apart."... By the way, I was not meaning that the matter and antimatter form a black hole together...I was saying that if there is an ANTIMATTER BLACK...

Phinds: Thanks for the response...however, first of all, there were a few people (more than one) responded, and none of them was trying to use cosmological constant to convince me that the universe is unchanging...second of all, the response was more involved...I even asked why we don't see...

A few years ago I came to this forum to ask about the issue of space expansion...and the answer I got then was that the expansion is the nature of the space (or space-time) according to relativity or some other more advanced theory...no one used dark energy to explain the issue at that...

Hi Guys: Thanks for all the kind response...sorry for that r^3 mistake...it has been long since I touched the formula in school... I am not a physics professional...my interest on the issue is from philosophical perspective...now based upon your responses I could assume that when a huge...
