    Since E=MC^2

    I have a question about energy.

    Since mass affects space time by warping it thus causing gravity (let me know if that's true or not I am not 100% sure on this). And energy and mass are welcome, so does energy affect gravity?

    Let's say I had a 1,000 ton nuclear bomb in the middle of the solar system, if i detonated that bomb right after detonation when most of the mass has been converted to energy and has not spread out yet, would the gravitational pull of the bomb remains + energy be the same?


    If it is that is amazing!


    Let me know, thanks


    Newbie to Science, trying to educate myself on this forum and further my scientific knowledge.

    I like to ask a ton of questions so please be understanding!

    I like to think of new stuff and in new ways.

    The right hand side of the EFE's is the stress-energy tensor. So, energy is one of the sources of gravity.

    Yes, all forms of energy are a source of gravity - this includes momentum, stress, flux etc etc. Gravity is also self-interacting, so certain configurations of "warping" can be held together by their very own gravitational self-energy, without any other sources being present.
