    Okay, but do they always spin like a bullet fired from a rifled barrel, with say, a right-hand or left-hand twist?

    They "have spin" in the sense that they have quantum angular momentum.

    They don't "have spin" in the sense that they're not "spinning."

    Turns out that on the quantum level, a thing can have angular momentum even if it doesn't have a physical size.

    Is there a direction to that angular momentum, say, like a right-hand twist on an incoming bullet? Or is it random?

    Somewhere, across untold billions of light years of space, on another gun forum, the members are discussing the same thing.

    All the Best,

    Nope, they're still stuck between 9mm and .45. :tongueout:

    We, on the other hand, have learned to rise above our latent cro magnon instincts and are firmly in agreement on the fact that...wait what? Did someone just yell "Freebird" again.

    Damn it, I was on a roll too!

    Nope, there is no one else out there debating caliber wars like us. No other intelligent society has survived the discovery of the 10mm.

    After a hard day of kicking Alien ass, Dr Shaw re-hydrates. She vows to never again go to crappy planets where the atmosphere won’t support a smoke break.

    I think I saw that movie (or pieces of it) on a plane this weekend. Prometheus? If that was the movie, they were not aliens...I think we were spawned from them, IIRC.

    Yup - Prometheus. But spawned or not they were still aliens so we might be splitting hairs. :supergrin:

    Besides, every thread can use a little Noomi goodness.

    This would explain the complete lack of intelligent signals received by us to date... :headscratch:

    It's not random; we talk about it as right-handed or left-handed twist just like on a bullet. When quantum angular momentum was first discovered people thought it actually was something tiny spinning like that, but we now believe that it's not. We're not really sure why things that aren't actually spinning have angular momentum, but they do.

    I am a conservative Christian and I believe that life possible exists elsewhere in the universe.

    I had an uncle who was a cop in the 1960's in Dayton, OH. He was working a night shift and he once told me about him and his partner out one night around 2:00-3:00am doing a patrol at a manufacturing plant that was near Wright-Patterson air force base. He said they had reports of some theft and vandalism at the plant when no one was there at night and could they keep an eye out maybe do an extra patrol.

    So they got to the plant and were out and were walking around, all was quite and he says him and his partner turned a corner and out in a field was a flying saucer about 100 feet or so in the air just hovering. He said they just froze and all of a sudden without a sound it just shot off out of sight in a second. He said they both stood there a minute not saying a word looking up and finally he said to his partner, did you see anything? No came the response. My uncle says, me either, lets get out of here.

    Curiouser and curiouser...

    I would appreciate your indulgence a little further...

    Are the occasional positrons detected in a collider like the LHC you work with, simply detected, or somehow induced by the device?

    If you have ever had a PET scan, you have had positrons formed and annihilated inside your body.

    No wonder it hurts so much, there was a tiny war going on inside! :wow: :whistling:




    J/K PET scans don't hurt.

    So, these machines, the PET scanners and colliders induce antimatter (a/k/a positrons)? :eyebrow:

    With a PET scan a radioactive tracer isotope is injected into the body. It undergoes positron emission decay. The positrons annhilate electrons which causes a pair of photons to be released which are detected by a scintillator-photomultiplier
