Its a space of 1meter×1meterx1meter, basically a cubic meter where the matter replicator works on. (So, no replicating cars, since its too big)
How do you min-max this?

It only takes one person to make 1 cubic meter of black hole to destroy the biosphere by ripping Earth into an acretion disc.
I like the concept of destroying the biosphere by shredding the entire fucking planet, lol.
Using a calculator I referenced further down in the thread, a back hole with a 0.5m radius so that the event horizon would fit within the cubic meter would have a mass of over 56 earths. We’d be proper fucked!
Talk about giving power to the masses, governments beware or we go boom
So you would have to replicate a percent of the mass of the sun. Seems feasible. The electricity bill would be nuts, but the world is ending anyway.
Use the replicator to make power duh
It’s a matter replicator, I don’t think a black hole is matter?
super dense matter
A black hole is nothing other than extremely condensed matter.
Ah, i thought it was a hole in space or something like that, so the absence of anything, and even space was something, but not matter specifically.
It is worthwhile to note that the above is highly reductive. A “black hole” is the sort of “hole” in spacetime you’re thinking of. It is caused, however, by gravitational dilation of spacetime by an incredibly high energy density. If you stuff enough matter and energy into a tiny enough space, the gravitational force will be strong enough that no other force in the universe can keep it from getting closer, and closer. Even the forces which keep neutrons and protons from combining with each other will be surmounted, as the energy density increases asymptotically toward infinity. This tiny point of effectively infinite density is the black hole’s “singularity”. Surrounding this singularity is a region where anything (matter, light, space itself) that gets within that range cannot escape. This is because objects have escape velocities based on their masses. If you’re going fast enough, you’ll fly away from the earth never to return. If you’re not going that fast, eventually you’ll fall back down. The further you are from the earth, the easier it is to escape it. The “black” part of the black hole, called the “event horizon”, is the distance from the singularity at which the black hole’s escape velocity is equal to the speed of light, meaning that, closer than that, nothing can escape it. Hence why it’s “black”, because no light is escaping from it. Technically, a black hole is not perfectly black due to hawking radiation,
and a black hole with a 0.5 meter schwarzchild radius would probably be small enough to visibly glow (just a bit).(probably not, see below)According to a random black hole calculator I found, a black hole with a 0.5m radius would be over 56 earth masses and the temperature would only be 0.000364 K. So, still orders of magnitude less than the cosmic microwave background.
I know smaller black holes evaporate faster, but even that little thing (according to the calculator) would have a lifetime of a gargantuan multiple of the age of the universe. Like roughly a number followed by 45 zeros, times the age of the universe.

Thank you! I didn’t feel like checking with the difference in masses, and based my assumption on Stephen Hawking’s statement that an earth-mass black hole (with an event horizon the size of a pea) would glow from Into The Universe: The Story of Everything. It seems he exaggerated, assuming this calculator is accurate and my understanding of its values is fair. Such an exaggeration is disappointing, if not entirely surprising.
A cubic meter of the core of a neutron star would still count as matter. While it probably wouldn’t literally destroy the Earth, I wouldn’t want to be on the same…continent…when that thing went off.
