If anyone is interested, this is a link to a recording of the show. He gives precisely the answer I was looking for at 13:30 and speaks about it for about a minute and a half.

That is correct, all energy has inertial or relativistic mass. What I meant and should have said, is that not all energy has rest mass.
Mass and energy can't be equivalent, because they are defined so differently.
Scott
Calling them equivalent is not really correct.
You could perhaps say that matter is a type of energy or matter has energy, but some types of energy do not have mass and thus could not be matter.

Are there dimensions within dimensions? These are my thoughts.
The answer to this depends on how you define a dimension. Depending on your point of view and the terminology you use, you could say that there are dimensions within dimensions. Different models in physics do not necessarily use...
I had thought yesterday that because e=mc2 implies that the speed of light is constant (or perhaps it would be better to say that special relativity states that the speed of light is constant), that that might be enough to prove the LoCE using e=mc2. I was unsure how to prove that.
Today, I...
I believe that special relativity proves a special case of the LoCE, but not its entirety.

Thank you for your thoughts, ppl.
I believe this is incorrect. I am with George and his explanation. Example: Being a man implies you are a human, but being a human does not imply you are a man.
That is correct. It can be derived in many ways, at least one of those ways uses the LoCE...
Hello,
First post. Thank you for letting me be a part of the discussion.
My question is, can the Law of Conservation of Energy, http://upload.wikimedia.org/math/2/7/3/273abc16486177bf6cc4c8ec4a4a5fc9.png, be derived using E=MC2.
I understand that the E=MC2 can be derived using the LoCE...
