    pikpobedy liked post by Useful Idiot On thread : Measuring water pressure in long flexible tube.
    Before applying any change equivalent to squeezing the tubing the required force is pA, pressure times piston area. This is the initial static condition. Squeezing the tube is equivalent to adding...

    Just a quick check on that displacement of 60 km to the point where the gravitation and boyancy forces match means that the Inner Core is drawn through 377 km of Outer Core liquid metal with most of...

    pikpobedy liked post by SinceYouAsked On thread : The gravity well and the hollow sphere
    The force of gravity is zero inside the hollow sphere, but the gravitational potential is not zero. Far as GR goes, Imagine a heavy hollow bowling ball at rest on a very large trampoline. It puts a...

    pikpobedy liked post by Markus Hanke On thread : The gravity well and the hollow sphere
    SYA's explanation of it is essentially correct. Space-time inside the cavity would be completely flat, however, the metric tensor would differ from the Minkowski metric at infinity outside the sphere...

    I'll just make this slight edit: The gravitational potential inside the hollow sphere would be essentially that that exists at the inner surface of the shell, and that gravitational potential...

    I have been interested in this problem for a while now. The accepted solution seems to be one offered by Dr. Gron in this site: http://areeweb.polito.it/ricerca/relgrav/solciclos/gron_d.pdf ...

    Interesting, However, a trace is not a physical entity that moves. It's a collection of impact events of different photons upon your sphere at different locations over duration. Agreed, the...

    Consider this pattern. 4!=\frac{5!}{5}=\frac{120}{5}=24 3!=\frac{4!}{4}=\frac{24}{4}=6 2!=\frac{3!}{3}=\frac{6}{3}=2 1!=\frac{2!}{2}=\frac{2}{2}=1

    pikpobedy liked post by Markus Hanke On thread : Why can we not regard gravitational time dilation as a "real" effect?
    That is trivially wrong. Time dilation is a function of distance from a mass, it applies to a clock in orbit just as it does to a clock on the surface, and is always relative to an unaffected clock...

    The electric field is zero inside a hollow charged sphere (Gauss's law (http://en.wikipedia.org/wiki/Gauss%27s_law)).
