    Yeah, then it's no longer light and therefore not in the "EM Spectrum". What exactly is the frequency of an electron/positron pair that puts it into the EM spectrum?

    Anyways...back to the subject.

    If it were not for Dark Matter existing the amount of regular mass comprising a Spiral Galaxy would not be enough to generate enough Gravity to hold the stars and solar systems existing on the outer arms of the spiral galaxy from being flung into deep intergalactic space.

    The photon must have higher energy than the sum of the rest mass energies of an electron and positron (2 * 0.511 MeV = 1.022 MeV) for the production to occur.

    I would have to look up the rest.

    It's not something I memorize.

    I wait with baited breath. You still have a homework problem to solve.

    Oh come on!!!

    I could look this up in a few minutes!!!

    I do not memorize everything!!

    Some things I do.

    :roll: Do you believe everything 'cosmologists' say without question nor proof, Alpha, no matter how ridiculous and outlandish it is? What about the latest 'news' - "http://edition.cnn.com/2016/02/21/world/far-side-moon-music/" - which turned out not to be music from the far side of the moon? [​IMG] And the video - can't you comprehend how childishly condescending it is? The 'Wooooo' from one of the 'astranarts' for example? Can't you tell that you're being fooled?

    Why not copy and paste it then, like you do with everything else you post? :mrgreen:

    You are comparing the Music Story to the discovery of the Higgs-Boson??? And the Higgs Field??

    LOL!!!

    First of all I could not reply as fast as I do if I did not know most of this by heart.

    Secondly I could have just looked up his frequency question but I did not know it off the top of my head so I admitted it.

    That's more I than I can say for many other posting members.

    Now you're doing what broadcast interviewees do when they suspect there's an awkward question about to be asked - they trivialise the conversation as a diversion.

    Has it been a few minutes yet? Sorry, that's unfair, a week perhaps?

    Oh for crying out loud!!


    10 exahertz (or >1019 Hz.

    Happy now?

    AA, et al,

    I knew what you meant; but I think you said it wrong.

    (COMMENT)

    ONE Exahert is equal to ONE quintillion ( 10^18 ) Hz. So TEN Exahert would be equal to 10 quintillion.

    I can barely grasp something on the order of a trillion (10^12) or a TeraHz.

    (SIDEBAR)

    As to a "Quintillion" --- I know what the definition is, but it exceeds my comprehension in any real sense. For instance, I know that the computational limit of the best 64-bit CPU is a finite state ≈ 9 Quintillion (9.22×10^18); but actually it is meaningless to me. You might as well say "infinite" to me because my mental resolution could not tell the difference (although I find the concept of infinite to be a paradox). (If you are working on something in the real world and you get an infinite answer, then it is wrong.)

    Most Respectfully,
    R

    Your right.

    I was just ticked off he got me to look it up as there is no need to memorize this specific to what I am working on that being attempting to mathematically prove Causality is dependent upon Virtual Quark/Antiquark Pairings Numerics within Hadrons.

    Thanks.

    Oh yes this is incredible, a Nobel prize for sure, I love how they managed to detect the waves, the 1.5km L shape pipes with split laser and mirrors, the bending of spacetime causing the incredibly small differences in measurement.

    When my kids were very little they would ask me how we managed stay on earth if the earth is not only turning, but also moving and round. I used the standard Newton explanation, gravity is the influence the mass of a larger object has on a smaller object and while that is still true we now know it's because of gravity waves... the bending of spacetime, fascinating.

    I was asking you to derive the 9.8 m/s^2 acceleration at the surface of the Earth due to gravity without using forces. Not surprised you can't. And your frequency of electron/positron pairs is absolute nonsense.

    Falling is not a Force but Effect.

    And the acceleration of any falling object in a vacuum is specific to the Inverse Square Law of Gravity.

    Thus the Mass alone of a celestial body is not the only determinant specific to this acceleration as so is the Diameter.

    This is why a 100 lbs person on Earth weighs approx. 34 lbs on Mars even though Mars has only 10% of Earth's total mass.

    And I am not the one having confusion as far as your previous question as that is YOU.

    Well something I just learned is that these gravity waves get us into Faster-Than-Light signal transmission and even travel.

    Creating spacetime shortcuts with gravitational waveforms without exotic matter for possible FTL communication and FTL travel

    Wow, we're getting into all sorts of advanced things now.

    Thank you. I thought you might like to see that.

    But actually you probably already got that didn't you?

    You know when I post there is always a percentage no matter how small of my posts I might make a mistake.

    I did in the above by not typing...10 exahertz (or >10^19 Hz.

    I mistype and missed the......^.

    And a member jumped all over me and another nice member posted they UNDERSTOOD what I was trying to post and understood my mistake.

    Nice member.

    Oh, I wasn't talking about your exponent mistake. I was talking about earlier when you told be that gravity waves actually make the distance shorter.

    But I didn't put the pieces together to figure out that a signal or a ship could use the shorter distance too.

    Earlier in the conversation about gravity waves I didn't know what the useful applications would be about its discovery.

    ...

    Yeah....Gravity Waves not only change Space and Distance but Time.

    Many people have a hard time wrapping their brains around this.

    You don't even want to see the spaghetti noodle approach I use to try and comprehend such things.

    No wait it's closed timelike curves that make me think of spaghetti noodles.
