+ Show Spoiler [hint] +General covariance and background independence
General covariance, also known as "diffeomorphism invariance", is the invariance of physical laws under arbitrary coordinate transformations. An example of this are the equations of general relativity, where this symmetry is one of the defining features of the theory. LQG preserves this symmetry by requiring that the physical states remain invariant under the generators of diffeomorphisms. The interpretation of this condition is well understood for purely spatial diffemorphisms. However, the understanding of diffeomorphisms involving time (the Hamiltonian constraint) is more subtle because it is related to dynamics and the so-called problem of time in general relativity. A generally accepted calculational framework to account for this constraint is yet to be found.

i have discovered a truly marvelous proof that at a certain level it is impossible to split spacetime into smaller quantities. This post is too narrow to contain it.

For some reason, after reading this, I lost the game.

i have no god damn clue wtf is up with that all i know is that i want a key but i wont get it from here.
The answer is really hard

Have fun! It is really easy!
1. String theory
2. continuous
3 force mediated by a hypothetical graviton aka the 13th diminsion
4No
i gave it a shot...

pretty sure this is a troll

1. Magic
2. Spacetime is either fundamentally continuous or discrete
3. Maybe
4. Probably

All of the theoretical divergences are the product of non-linear wave functions of gravity in the 4th and 5th dimensional plane. The reconversion of gravitational material from informational wavelengths provides for irregularities at both the micro and macro level. Naturally enough, it follows that spacetime is NOT discrete. The ultimate preservation of information in the form of the graviton or a supra-spacial wavelength provides for this consistency.

Do we really get beta keys if we answer this? Since there are only theories to these questions, I will form my own theory:
"What the hell is Quantium Mechanics? I'm not taking AP Physic yet"

Nice attempt at throwing together some bullshit. Sounds somewhat legit and consistent, but I know just enough about the subject at hand to know this is BS.
