Some serious questions

[Fallingstar1971]

1. What is the biggest, most massive, and physically largest things ever measured with Relativity, both general and special?

2. What is the smallest? Where is the exact point where they break down?

3. What is the Largest thing most accuratly measured with Quantum Mechanics?

4. What is the smallest?

5. What is gravity? Is it a side effect of mass? Does it have particles? If it can travel in waves is it another form of light? Of Energy?

6. If all the forces (Gravity, Strong/weak nuclear force, Electromagnetic force) were combined into one massive Superforce, what kind of properties would said force have? Could these conditions exist at the hearts of black holes?

I'm not entirely sure what you mean here. General relativity and quantum mechanics are theories. You can use them to describe how objects behave, but they're not devices which we can use to "measure" things. Unfortunately, I'm not sure what you're getting at.

5. What is gravity? Is it a side effect of mass? Does it have particles? If it can travel in waves is it another form of light? Of Energy?

Sure, to all of these. Mass and energy cause spacetime to "warp" - this warpage effects the motion of objects, and it's that motion we call gravity. Gravity is believed to be mediated with a particle called the graviton, which has not yet been detected. Similar to how photons (which carry the electromagnetic force), or light particles, are also electromagnetic waves, gravitons are carried by gravitational waves, which we hope to detect within the next few years, and study intensely over the next few decades. Gravitational waves do carry off energy - in fact, when two very relativistic objects orbit each other, those orbits will decay because orbital energy gets transferred to gravitational energy, and radiated away in gravitational waves, until the orbits decay so much that the objects collide and merge. This effect was noticed in the decaying orbits of two neutron stars in the 1970s, the so-called Hulse-Taylor binary, which won Hulse and Taylor a Nobel Prize.

6. If all the forces (Gravity, Strong/weak nuclear force, Electromagnetic force) were combined into one massive Superforce, what kind of properties would said force have? Could these conditions exist at the hearts of black holes?

This force would presumably exist anywhere, and knowing its properties would be very helpful to understanding what happens in black holes
