    Still warming up to destroy the earth, the Large Hadron Collider in Switzerland/France was again used to produce antihydrogen atoms which the scientists now trapped for entire 1000 seconds inside a powerful magnetic field (About 16 and a half minutes) setting a new record for keeping antimatter in existence in our universe. (Thats artificially created antimatter. No one knows if it may happen naturally somewhere)

    I know very little about Astrophysics. I do know that 99% of an atom's total mass is empty space.

    That being said, it amazes me that most of the obstacles we see and encounter on a daily basis (mountains, trees, buildings, etc.) are made up of 99% empty space. Then again, that only hints at what little it should take to overcome ANY obstacle.

    Seeing that I know so little about such things, I'm going to venture an uneducated guess here. In light of the fact that atoms are always in motion, even if just within themselves, I propose that Newton's Third Law of Motion should be considered applicable here in addressing how much antimatter exists, if it actually does exist/occur naturally.
    "For every action (atom), there is an equal but opposite reaction (antimatter)".

    Don't know if this reflects reality or not, but Newton's Law immediately popped into my mind when I read of your ponder over antimatter.
    I know, it's a pretty thin hypothesis.

    I know, it's a pretty thin hypothesis.

    You are on the right track of thinking, better said you are not.
    But dont worry the entire physics world was on the same track until the CP violations were discovered.

    Using Newton's Law as basis of thinking , it would be just logical to come to the conclusion that for all the matter created in the big bang, an exactly equal opposite force must have been created with exactly an equal amount of antimatter being blasted into existence in that very same moment. All the laws of physics we can observe support exactly that idea and way of thinking.

    BUT this would mean that both masses of matter and antimatter would have annihilated each other instantly leaving not the universe we know but space filled with absolutely nothing.
    Obviously this did not happen as we, like the earth and anything we can see out there in the universe obviously are not a space of nothing but really exist and all of that is made of matter.

    So, the big question researchers all over the world trying to answer since decades is : "How can that be at all ?" , "What happened to all that antimatter ?" and "Why did matter triumph over antimatter if our understanding of physics says that none can triumph over the other if the same laws apply to both ?"

    The most likely answer at the moment is : "Contrary to all we believed so far and that seemed logical to us, the same fundamental laws of physics do NOT apply to both afterall. There are exceptions where no exceptions should exist."

    And the discovery of the CP violations supports this

    Better said, there should be no exceptions when our current understanding of physics was 100% correct. Obviously we are not 100% correct which is not a bad thing of course and was expected.

    We're still learning afterall and like every student we just cannot but get a lot of things wrong before we finally completely understand them at some point



    Baryon asymmetry is a good example for this

    Not bad though, for a guy w/o a degree and whose last college course was back in early 1988.

    Looking through my photo archives i just stumbeled upon this



    Its Teddy Suhren's famous torpedo transfer between U-564 (Suhren's boat) and U-154 on the open sea and without proper equipment.

    They simply strapped lifevests to the torpedos to keep them afloat
    Luckily, Suhren's boat had a war reporter aboard so this was even caught on film.

    Just one of the many "stupid ideas" of Suhren which somehow worked out

    Here is a nice photo of the Wilhelm Bauer when she was still in service with the west-german navy in the late 1970s. (Her first name was U-2540)




    Another level of modification. Later or earlier , dont know.



    For the museum display, her conning tower was reversed back to its ww2 design.



    Revell offers both versions








    And this is a submarine designed in 1850 by the man the Wilhelm Bauer was named after

    It was supposed to attach explosives to the hulls of danish warships but it already sank during its trials, propably because of a malfunctioning valve in a ballast tank.

    The crew of three (Including Bauer himself) was trapped for six and half hours on the bottom of Kiel harbor but managed to escape after flooding the sub until the pressure allowed them to open the hatch.

    This was propably the first succesful escape from a sunken submarine in history.

    My son had a reprieve from classes in Arizona so he and some friends went on an excursion to California. He visited L.A. and Hollywood and sent me some pics.

    A night photo taken from a nearby observatory. Some of you "Rebel Without A Cause" fans may recognize this observatory from the James Dean movie:




    A Russian "Cold War" sub, The Scorpion. That's the Queen Mary next to it:

    Ah, so you got yourself one too.
    Looks like a Foxtrot class


    We have a Tango class now called U-434 (as all submarines here must have U-designation) but its original soviet name was B-515.

    It was once owned by the KGB and had special modifications like anti-sonar coating for espionage missions in u.s coastal waters.
    Propably keeping an eye on Sarah Palin's house and stuff

    It was also present at the u.s navy blockade line near Cuba during the crisis. ( Thats what the museum claims but this actually cannot be true as the Tango class entered service in 1972 , full ten years after the crisis)

    Now its on display in Hamburg

    P.S: When your son took that photo of the hollywood sign, he was pretty close to the street where my sister lives.
