1 kilowatt-hour (roughly the energy consumed by running a toaster for 1 hour) is equal to 4.0055402e-11 grams of matter.

The laws of thermodynamics apply to things on the human scale - on the quantum or universal scales they may not hold.

After doing this, scientists though that it must work the other way around, so they collided two immensely powerful units of pure energy together, and two small particles magically appeared, so yes, matter is never created or destroyed, it only changes form... even if that form is energy.  We need to come up with a word that describes mass and energy together.

The first respondent confirms this.

is it possible to create what we consider matter [things we can see/touch] not at this point in time. the fermilab accellerator [a VERY large one] drains half a city's electric, and still cant produce many particles. however, is it possible to create particles from energy at this time, yes.

You cannot just convert an electron to energy just like that. That would violate the conservation of spin and the conservation of charge. Also, electrons are affected by the strong and weak interaction, whereas a photon is not. A positron is required for the event to take place.

Energy and mass are different manifestations of the same thing.

norock, that user is most likely speaking of pair production.
