    Are there different shapes of explosions in outer space?

    Assuming something is not manipulated by gravity, does every explosion radiate equally in 3 dimensions?

    Assuming the explosive was spherical to begin with, the explosion will always be a nice sphere. If the explosive was shaped differently, the explosion will be too, but as it spreads, it will tend ot get more and more spherical as the differences even out.

    and this is also providing a consistent explosive, change the density and it changes the shape, mix explosives poorly (inconsistencies throughout the whole of the explosive 'thing') and it will create variations through the explosion that will result in something different than a sphere, even in the long haul, because parts of the expanding wave will be moving faster than others.

    alright, common sense, just had to ask

    so, everything that exists as it is in the universe can be used to understand the inconsistencies of the theoretical singularity that was once the universe right?

    The Big Bang was not an explosion in space. If it was anything it was an explosion of space. Quite a different matter.

    can we assume that the universe has expanded in all directions equally? In which case wouldn't the outcome be the same?

    Well, sort of, except that the universe can be blasted from a singularity, be infinite and be expanding all at the same time. Then trying to determine if it's expanding uniformly might get a bit tricky. Maybe someone else can give a better answer than that though.

    the shape of the universe was for a microscopic moment based purely on the shape of whatever singularity exploded forming said universe

    as soon as matter appears it will have begun to affect the other matter around it distorting the original shape, today the shape of the universe is based on how the gravity has affected matter near it, the earth for example exerts a gravitational pull on the sun albeit tiny (it makes the sun wobble slightly) all matter has an identical effect on all matter in it's immediate surroundings and possibly on all other matter in the universe,
    In truth the only thing about our universe still based soley on the Big Bang's explosion is the overal velocity of all of matter, because all matter is traveling through space, the original velocity has never diminished, it's just been moved (einstiens "every action has an equal and opposite reaction" on a galactic scale)




    In answer to your question assuming gravity was non existant in all forms, the explosion would be in the shape of the exploded thing, i.e an exploded car would be car shaped it will just get less defined as the particles spread out, but it will never change shape to form a sphere or anything except an expanding car because there is no gravity
