What is energy? According to Physics theory, energy is defined as the amount of work that can be carried out by a force. Energy is a physical scalar (meaning that direction is not accountable) quantity. The SI (international system) unit for energy is Joule (J). Petroleum is a source of energy. It refers to the crude oil derived from Mother Earth. Processing crude oil gives refined products like gasoline, heating oil, diesel fuel and many others. In our daily lives, there are many refined products from petroleum ranging from food items to medicine! For further information, refer to http://www.renewableenergytoday.org

E=mc2
E = energy
m = mass
c = celeritas: Latin meaning "swiftness." In this case the speed of light in a cold hard vacuum. 671,000,000 miles per hour.
2 = in this case, to square or multiply an amount by itself.

Energy equals mass times the speed of light squared.

So, to answer your question Gina Roberts, energy is mass, mass is energy, they are one in the same. There is mass in light and light can be defined as pure energy. We and everything around us was at one time light and, we and everything around us will eventually return to being light.

"The human mind is not capable of grasping the Universe. We are like a little child entering a huge library. The walls are covered to the ceilings with books in many different tongues. The child knows that someone must have written these books. It does not know who or how. It does not understand the languages in which they are written. But the child notes a definite plan in the arrangement of the books---a mysterious order which it does not comprehend, but only dimly suspects."
A quote from the late Albert Einstein. May God rest his soul.

Personally, I have a tendency to see things from a perspective that, where and what we are, is somewhere within a macroscopic-microscopic continuum. If we could have a microscope powerful enough we may just be able look so far as to see the back of our head as we peer into the microscope and vise-versa.

Could what we have come to know as "gravity" be one and the same as what we know to be "molecular cohesion"?

Not to get picky, but...

the speed of light is 186,451 miles per second, or - in science - 300,000,000 meters per second.

Thomas, Einstein 's theory of relativity referred to rest energy mass, E. His point was that there was some amount of energy proportional to the mass of body...E=mc2.Mass is matter!Mass is not energy!Energy is mass and mass is energy is a new theory, Thomas, not dear Einstein 's...mass can be destroyed...energy cannot,only transformed into another form..
