Because there is a law of nature that says that matter (mass) can neither be created nor destroyed. However, Einstein proved that mass and energy are actually the same thing (E=MC2), so mass can be turned into energy and energy can be turned into mass.
we can`t with the technology we have today we can only convert like one billionth of a percentile of mass into energy, if we could eventually do it a glass of water could power the world for a long time
With mass AND heigth
Almost. The law actually refers to the conservation of mass/energy. Energy could be converted to mass, and thus suffer reduction. Actually, the energy of the universe may be increasing gradually, as hydrogen fusion liberates a small fraction of mass (the mass defect) through standard stellar nucleosynthesis.
No. Energy has an ASSOCIATED mass. There is no such thing as mass-to-energy conversion, or energy-to-mass conversion. In a nuclear reaction, for example, BOTH mass and energy are CONSERVED. For a more detailed explanation, check the Wikipedia article on "binding energy".
Photosynthesis is an example of turning energy into mass. E=mc^2 is how energy is turned into mass.
Albert Einstein, with the equation E=mc2.

Yes, a Photon's mass is theorized to be zero.
Einstein theorized that in the same why mass was energy, time was space. So, in effect, time could be nothing more than a simplification of the three dimensions we live in.
Einstein's famous formula is the formula for the mass-energy equivalence: E=mc2 This describes how mass can be turned into energy and vice versa. Thus E,energy= mass X speed of light x speed of light (a very big number). This means a tiny amount of mass converted to energy is huge and is why atom bombs are so powerful.
This is a tricky question. Quantum mechanicss shows us that all energy can be turned into mass and all mass into energy. To work out the equivilant mass of an amount of energy (or vice versa) simply use einsteins famous equation E= mc^2 - rearrange m = E/c^2 I do not know of any device that can directly "weigh energy".
The energy in chemical bonds (from food) is turned into:kinetic energy (moving mass), noiseheat (shoes heat up , the runner's body get warm)
It is precisely because of it's mass that it's even theorized that Dark Matter exists. We notice the movement and behavior of certain areas of space far from us that we cannot see the matter that is effecting it. It was theorized that there must still be something that is affecting that space, regardless of whether or not we can see it. This unseen matter is called Dark Matter. If it did not have mass, it would not be affecting the space around it, so it's purpose for being theorized would be meaningless.

If you talk about fission reaction (current nuclear power plants) then the mass is turned into energy, mostly in a form of heat, that is then turned to make energy in a massive closed system steam turbines plant.If you really mean Fusion reaction (humans not able to replicate such, but such is known to happen in stars), then there are no missing mass.
