Isnt the energy that it took to assemble the mass together equivalent to the energy to break it appart?and when it breaks apart teh components of the mass will fly at the speed of light?
so if power is given to a mass to move at the speed of light it would take along time to disassemble at that point the mass structure wouldnt it break apart with the energy of mc^2.?

isnt Mass a completely different concept from the concept of Energy?How can one be converted into another concept?
Where mass is ameasured quantity in kilograms and the process of energy is in terms of kilograms times meter squared divided by time squared?They are not the same are they?

Objects with mass can merely approach the speed of light.

Actually, massive structures can never reach the speed of light as it would require infinite energy for the required acceleration.
Yes - The TOTAL energy that was used to make the structure would be the amount of energy used to break it apart. To break it apart entirely would be the amount of E=mc^2. But remember, that would be the amount of energy required to completely obliterate it from matter and mass to actual pure energy, and it would also be the amount of energy released.
As something accelerates it gains more mass because it is gaining more kinetic energy. This makes sense algebraicly because "c" is a constant and cannot be changed if E is changed. Now, due to momentum, if you were to get this massive structure NEAR the speed of light (but not at the speed of light, as explained above), the components would break away at a vector velocity proportional to the objects overall speed. That is to say, if the structure begins to break down, and there are no other directional forces acting upon each component, they will maintain the same speed as the whole unit, provided the force of the power applied is uniform throughout the field. Now eventually, provided constant application of the power source, all of the matter will break down into electromagnetic radiation (energy) which has no mass, because it is pure energy, and can therefore reach the speed of light.

1. Yes, assuming no energy losses.
2. No. The components will not fly at the speed of light unless you mean that the entire mass is converted to energy.
3. As a body moves approaching the speed of light, the mass increases. It would not break apart.
4. mc square is the equivalent in energy of a certain mass if converted entirely to energy.

Hi. "Glue" the energy together and you get mass. Change the mass to energy and you get energy equal to the "c squared" part of the equation. The speed of the object has little or nothing to do with it.

uhm, the speed is irrelevant. besides, there is no way you can alter the speed of light but by light itself.
