    I'm wondering if there is an energy cap? More specifically, if there is a maximum amount of joules that can be emitted per unit of area?

    Just as the speed of light is (supposedly) the cap of speed, I'm wondering what the cap on energy is?

    Thanks

    The energy cap is how much energy you can put into one area, since it will be trying to get out again. Realistically, probably a hypernova, which is maybe a hundred times as powerful as a supernova.

    well I think that theoretically piling enough energy into one point transforms the energy into mass, (aka the big bang) so the question then becomes how much mass can you fit in a single point? this is also known as a black hole

    so find the capacity mass of a black hole and plug that into E=mc^2 to find how much energy can be put into a single point

    It all depends on how drastic a measure you're willing to go to to contain it. A black hole represents insane amounts of contained energy.

    If you're talking about maximum amounts of energy that can be contained, and then emitted, that's really hard to say. At some point, if you cram enough energy into one place, it will probably start converting into matter.

    Energy is the capacity to produce change. The point at which energy cannot move matter would be it's cap. For example, as an object gets pulled into a black hole there is a point of no return at which no amount of energy can free the object from being pulled into the black hole.

    So would you say the energy cap is the point where it would take an infinite amount of energy to repel an opposing force?

    Yes, like if you try to cause something other than light to reach light speed the force against it doing so are overwhelming.

    I think if you were to focus enough laser light energy into some given unit of area in space you would warp space so much that you could possibly create a wormhole. That may be the other cap you are looking for.

    Well...how big is this unit of space supposed to be?
    For example, can anyone fit more energy into the space a quark takes than the amount of energy the quark has itself?
    I am.
    You can't deny it.

    I think Planck units are as small as it gets.

    The size of the unit of space is irrelevant.

    If it were, for example, 1 Million Joules per 1mm, it will scale, going upwards with 2 million joules per 2mm, 3:3, etc.

    So if it could be found in either 1mm^2 or 1km^2, the scale will be the same.

    If you're asking about a flux (energy passing through an area), then it doesn't scale linearly with volume. The volume of a sphere is while the surface area of the same sphere would be .

    Flux would be proportional to surface area, but density proportional to volume. I think you can use this to show something, but I can't think of what right now. :P

    There is mass cap, so I would suppose that there is an energy.

    At the mass cap, gravitational force (attractive) is theorized to become repulsive.

    Can you find a link that explains the "mass cap"?

    Its not called a "mass cap", I referred to it as such, in light of the OP -- but yeah, I have a link...

    Look into Big Bounce Theory and Loop Quantum Gravity.

    if no amount of energy can free something from beyond a black holes EH that implies nothing can escape a black hole

    which isn't true, the names elude me at the moment (hawking radiation I think) but stuff does come out a black hole, implying black holes are not the energy cap, rather they are a mass cap, no matter can escape except in the form of energy

    No. I'm relatively confident that is incorrect. Nothing can escape a blackhole once it has crossed the event horizon. The Hawking Radiation you mentioned operates differently than you imply. IINM, it has nothing to do with radiation escaping the blackhole. The idea is that a particle/antiparticle pair is created right on the edge... right at the precipice... of the event horizon... and occasionally, since this pair is produced right on the edge of the event horizon, one of them will fall into the hole while the other escapes. However, if they are within the boundary of the EH, then they cannot escape.

    ahhhh, ok then, I stand corrected
