    Gravity goes weird?

    I'm suprised this is old news as I only read a new article a few days ago on it. Sorry to bore you zapper. ;)

    Gravity goes weird?

    I can't believe no one thinks this is worth commenting on! :) Basically it is saying there are strange things affecting the pioneer probes that are unexplained and may show that gravity acts differently than is explained by current theory.

    Gravity and angular momentum

    I have been told emphatically that there is no such force as centrifugal force and to use the phrase angular momentum when referring to what it referrs. Centifugal force then. Centrifugal force seems like a pushing force and gravity seems like a pulling force. Would there be any subtle...

    Gravity and angular momentum

    Is angular momentum a push and gravity a pull? I just thought there might be unforseen differences in human reaction on a spinning space station.

    Magnetic fields

    photons If photons in a magnet are strong enough to push another magnet away, wouldn't it take a phenominal amount of light to do this? Also, if photons are being emitted at such a high rate, why is no heat felt from the magnet? If photons carry the magnetic charge, why is light from the sun...

    Magnetic fields

    So why dont the magnets run out of photons? What wavelenth are these photons? Does this mean that by sticking a light collector near a magnet we can get free energy ad infinitum? Please explain.

    Magnetic fields

    Is a magnetic field carried by a particle? If two north ends of a magnet are brought together they push apart as if they were two rivers meeting head on and if a north pole and a south pole are brought together it is like two rivers flowing together in the same direction. What are these...

    Why does hot air rise?

    Perhaps Perhaps it is not so much the hot air rising but the cold air around it sinking, its pressure pushing the warm air up?
