of course energy can be created- e n e r g and y, there you go!
energy is generated from the transfornation of state of an element posessing mass and stored potential energy.

And indeed, anything at any distance above the earths surface requires more energy to put it there, than would be gained by allowing it to fall back to the surface.
atoms do not attract one another.
the electron valiance of any atom dictates attraction to other elemental atoms.
if the right number of electron are on the outer valiance ring then given the correct catalytic conditions, then a compound will be formed

If that is the case what happens to the surplus energy required to lift it, where's it gone?
Not doubting what you say, just curious.
Only an object with zero (or indeed negative ) mass can travel at the speed of light.so if something is traveling at the speed of light squared, does that mean that all of it's mass dissapears?
not your old fashioned imperial.
Personally, I tend to think "FFS" in whatever unit of weight I use on the scales - 'cos I'm bilingual like thatJust as an aside, when you weigh yourself do you think, "My God I'm 'xxx' kg" or do you convert it to stones?
