Black holes follow from three principles:
1. The speed of light is limited
2. The force of gravity is not
3. Light is subject to the force of gravity
Based on this understanding, scientists first speculated about "dark stars" so massive that their light could not escape them as early as the late 1700s. The modern conceptualization of the black hole came about with the development of general relativity and quantum mechanics in the early 1900s.
If any of these principles did not hold, the universe and life as we know it would not exist, as with all of the laws of physics.

The concept of black holes follows from basic Newtonian physics. For black holes not to exist you need to assume either an infinite speed of light or an arbitrary upper limit on the force of gravity.
The modelling of what's actually happening inside of a black hole's event horizon is imperfect without a theory of gravity that works with quantum physics, but there's no doubt that they do exist.

It couldn't create a black hole.
Realistically, the only way to compress mass enough to form a black hole is for the mass to collapse under its own gravity. Any material in the universe (and anything containing it) would just be obliterated long before any physical force got close to crushing its atoms.
The cube, and any other object small enough to be pushed through a portal, is also a completely insignificant amount of mass and even if you could somehow compress it beyond its Schwarzschild radius (for a 10kg cube this is an area one billion times smaller than electron) the black hole would evaporate instantly.
To compress the entire Earth into a black hole, roughly one billion trillion (10^24) times more massive than the cube, it would have to be crushed small enough to fit on the tip of your finger.

You don't need to rewrite the laws of physics, Albert Einstein already did it for you 100 years ago
