    Gravity: Earth-sized platinum sphere with 3 meter empty center - behavior

    Thx for responding guys, Let's say there were symmetrical tunnels leading to the hole at the center of the sphere, such that you could slide down, finally coming to rest at center (after zipping into the opposite direction) Now, as you hang in the center, the two masses should be...

    Gravity: Earth-sized platinum sphere with 3 meter empty center - behavior

    of loose object in the center. This object is now surrounded by mass, will it hover exactly in the center of the hole, is there no gravity there ? If it is flexible, will it be expanded if it is expandable. How does one calculate this? (For realism, assume symetrical 2 meter channels from the...

    Read article on Pulsars, not clear how a sphere sources pole-only emission?

    Thx for responding. In the picture the beam is way too thin, should the emission not be way, way broader, (yet, we assume rotation is so fast). 1) Is there any possibility of replicating a magnetic-field controlled radiation emission from a sphere to form a so finely-focused beam ? (The...

    Read article on Pulsars, not clear how a sphere sources pole-only emission?

    The pole still has extremely strong gravity, how can a sphere suddenly concentrate the radiation at the pole to be emitted there ? As this is the only exit, should there not be a strong deformation ? How does the radiation make it to the pole, or, is the radiation we are getting only from...

    Gravity and Rotation: Exploring the Milky Way's Mass Increase

    Science news recently reported milky way rotates faster than thought - hence more mass. How does this work out for a single planetary body: If rotation is accelerated, my thought was: less gravity, bec. higher centrifugal force. Now, I'm thinking - more mass due to rotation hence more gravity...
