What would be the dangers of creating matter from nothing

+0

Dear top secret science network,

Humanity was visited by visitors from another universe altogether (one which doesn't obey our laws of physics) - the D'jini. A diplomatic convoy of them apperead one day in our linguistics research lab. D'jini have abilities that in our universe are simply physics-breaking but in their are more commonplace. The most interesting one is the ability to conjure food, creating matter from nothing.

The ability works as follows (as described by the D'jini):

  1. The D'jini makes skin contact with a concious and sapient entity with their left hand.
  2. The D'jini using their telepathetic abilities learns of what we would call "favourite food" of the touched entity.
  3. The D'ijini slowly conjures one serving on their (as read from the memories related to the favourite food concept - i.e. one large peperoni pizza or six sushi rolls or a bar of chocolate) of the food - displacing the air around their right hand slowly.
  4. Upon completion of the conjuring or if at any points someone breaks off the skin contact the D'jini is not able to use their ability for another earth week or so - the ability requires certain amount of heart beats to be recharged.

Obviously the ability itself isn't very scientific in our universe and we are afraid that trying it out may create some serious issues for us.

We can ask the D'jini if their abilities offer some kind of protection but neither them or us are trained in nuclear or quantum physics enough to know exactly what the dangers could be.

There is nothing inherently dangerous about matter that has been created out of nothing (indeed, that's how all the matter around us has originally been created). However the method itself can be dangerous.

In real physics matter is created when enough energy is concentrated in small enough volume. This is extremely undirected and it will create all sort of elementary particles and showers of radiation as by product. However, if you can somehow control what particles are created then in theory you could do this without harmful side effects.

But another possible danger spot is that the food item in question is created based on the memories of the subject. I don't know about you, but I have not committed to memory the exact chemical makeup of a slice of chocolate cake. How reliably can this method identify the components of the food in question? A chocolate cake is sweet, is that sugar? Or perhaps it is lead acetate? There is a distinct taste of a bitter alkaloid. Maybe it's theobromine from cocoa beans, or maybe it's any number of highly toxic alkaloids...
