In many places it is suggested that mass causes gravity. But this is not really true, since Mars and Jupiter (planets) which have massive mass, do not have that much gravity.
So, what is causing gravity, if not mass ?

The position of something next to me, I can accurately find. What about if time travel were possible? There is nothing absolute about position in space anyway - there is no real grid that the universe fits into, only relative positions. Something never tackled in sci-fi about this, is where would you be if for example, you went back in time by a second? Not on the Earth probably, maybe in it or above it. I can touch something and place an object on that, but can't reach back in time to position myself.

A person of mass 75 kg is standing on the tiptoes of both feet. The heel is lifted just above the ground, so the foot can be treated as horizontal. There are three forces acting on each foot; the upward vertical force N exerted by the floor on the toes, the downward vertical force F sub 2 exerted by the leg bone (tibia) on the ankle (talus), and the upward vertical force F sub 3 exerted by the Achilles tendon on the heel. The distance from the toes to the ankle is 12.5 cm, and the distance from the ankle to the heel is 6.5 cm.
(a) Draw a free-body force diagram for the foot, showing the relevant forces and distances.
(b) Applying the conditions of force equilibrium, find the magnitudes of F sub 2 and F sub 3.

A theory is generally accepted as valid due to having survived repeated testing

How can something that cant be tested be called a theorey?

Philosophy can be distinguished from empirical science and religion. The Penguin Encyclopedia ([citation needed]) says that philosophy differs from science in that its questions cannot be answered empirically, i.e. by observation or experiment, and from religion, in that its purpose is entirely intellectual, and allows no place for faith or revelation.

For example heat conducts through solids, but in air/gas it is radiated. How about in liquids, both? Is the only difference the speed?

I am trying to figure out how many kilowatt-hours of electricity my little electric fan heater consumes when I have it running for an evening or so. On the back of it is a little tag that says "2000W" and "50Hz". If I run this thing for an hour, does that mean it consumes 2kWh (sounds a bit high to me)? I mean, if it runs full tilt for an hour, and its performance is 2000W max, isn't that 2 kilowatts per hour?

Einstein's theory of relativity was proved experimentally by showing that light from a distant star was distorted by the mass of the sun during an eclipse. Light IS affected by gravity. Light "supposedly" has no mass, yet it is still affected by gravity. Is F=Gm1m2/r^2 not really the correct way to look at it? Is this just a simplified case? I understand that spacetime is curved and this is what really causes gravitational effects according to Einstein. Any "object" (photon, electron, with mass, massless) is affected by gravity because it is following curved spacetime. This tells me that the definition for gravitational force is incorrect. If the mass of one of the two objects is 0, then F=0. Both objects are taken into account when both have mass because they both warp spacetime around them, but if only one has mass, IT ONLY warps spacetime, but the definition does not leave room for this idea.

Hmmmmmmmmmmm..............?
