Just curios if energy has gravity?

[Bill S]

Yes.  Keep in mind that energy and mass are interchangeable.  It is mass/energy that creates gravity, or curves spacetime; depending on how you want to interpret it.

Does kinetic energy have gravity? It isn't the same as relativistic energy/mass.

[alancalverd]

No. Energy is a quantity that is conserved in classical interactions. It has dimensions of force x distance. Gravity is a force - different dimensional content.

Alan, was that "no" to Jeffrey's question, or to the OP question?

[JoeBrown]

if your going to tackle a question with relativity, you should first understand what relativity does,
what it answers and what it simply is not meant to answer.

Relativity doesn't answer why mass cannot reach light speed like photons, doesn't attempt to. It asserts it, w/out explaining.  Simply put, it's an understanding of nature w/out explanation, because the simple explanation requires it so, to be simple.  ( I like that.  I claim coinage. )

I don't believe your answer can be achieved using relativity, because of what it does and doesn't do.

I may be in the minority, so this may qualify as opinion, not fact.  I'm working on resolving that, with a paper the coin has been inserted into (slightly modified to fit form and function better).
