    It as got a question so I can be corrected/clarified.

    A velocity is a speed and direction

    A vector is a length and direction

    I get mixed up sometimes, there is much to remember.

    That's correct.
    That's correct, but only in a geometric sense; it's better to say "a vector has magnitude (or amplitude) and direction", where the direction depends on a choice of co-ordinates (but the magnitude doesn't, in general).

    You keep on about AGE not TIME

    What detects TIME please?

    Third time: what detects gravity?

    As Jupiter moved between Earth and the quasar, the gravitational bending of Jupiter allowed us to measure the speed of gravity, ruling out an infinite speed and determining that the speed of gravity was between 2.55 × 10^8 and 3.81 × 10^8 meters-per-second, completely consistent with Einstein's predictions

    For the first time, scientists have detected ripples in the fabric of space and time — known as gravitational waves — from a colliding pair of dead stars called neutron stars

    t=age

    age= change of S

    What is t - hint it is NOT age

    What is S?

    Please where is a photo of this time detector?

    t is time and S is entropy. Like I said , you think it does not exist because you cannot 'see' the existence in your mind. Your age is directly proportional to the time experience. Consider the snowman, while the snowman is ''alive'', time exists for the snowman within and as ''his'' entropy. The rate of ''his'' entropy being the key fundamental aspect of ''his'' survival. When the snowman ''dies'', ''his'' time was gone. The snowman and the snowman's time no longer existed. Time is independent to the snowman, the space around the snowman is absolute.

    I think this two way exchange has run its course

    You continue to try to say TIME is age

    The "life" of the snowman, from completion to meltdown is age

    Pity I was looking forward to a photo of a TIME generator or detector

    Ok, here is a photo of a time detector.

    https://www.google.co.uk/search?q=the atomic clock&source=lnms&tbm=isch&sa=X&ved=0ahUKEwiYiMChtZHZAhUCElAKHV80C1IQ_AUICigB&biw=1920&bih=949#imgrc=1yAqOOpMLmc4MM:

    This detector of time, detects time can slow down or speed up. The same as the snowman detects.

    Δf=Δt

    Where f is frequency.

    If you do not believe this formula works, I ask you to make some ice , leave some in the freezer and place some under a light, Δf=Δt

    I guarantee you the ice in the freezer will have more time than the ice under the light.

    This did not answer the question.

    What his detected was how long it took for gravity to affect one mass and then affect another mass, some distance away.
    We did not detect gravity; we detected its effect of Jupiter and the photons passing it.

    This is identical to not detecting time, but detecting its effect on a clock.

    OK

    I understand (I think) the Jupiter bit as is detecting SPEED of gravity

    How about the app?

    I should have my new sim card within the next two weeks and I know I can download the app and use it without a sim but....t will wait

    Seriously? You think that Apple has been able to do what the science community has not?
    You don't think that this app is derivative of some known scientific principle?

    Will find out in a few weeks

    "In a few weeks" does not exist.

    NOW - gravity is not directly detectable, just like time.

    In a few weeks is a vague measurement between the moment you requested and the moment I am able to answer

    https://en.m.wikipedia.org/wiki/Gravitational_constant#Law_of_gravitation

    I guess then I will be measuring the difference between the gravity attraction of the Earth to my body on one location on the Earth followed by another location

    Apart from that two weeks stuff I have not got a Apple. To expensive even in Bali. Have a Huawei Rio and new phone is also a Android Huawei

    I know it does not make a difference with the detecting gravity app

    Which brings up at least we do know gravity fields do exist.

    No such show for TIME

    Do you think time is in cahoots with god and they both have the same hidie hole?

    Kidding

    What would god want with time if you have always existed?

    Is gravity detectable? Did anyone else do a reaction test in physics? My partner drops a meter ruler and measures the time it takes for me to grab it. That is a measurement. Speed=distance÷time.

    Right. But you won't be detecting gravity, you will merely be detecting its effect on physical masses.
    Kind of like you don't detect time; you detect it with a clock.
