In the Compound Interest Universe, this formula measures the total Amount (A) that results from multiple generations of money spontaneously splitting and multiplying (1 + r/n)^(nt) from the original Principal (P) over Time (t).

Part 2: Tying the 3 interest formula universes together with their formulas. (imaginary physics analogies)
Here are the standard interest and annuity formulas labeled according to characters in the imaginary universes:

Simple Interest Formula:
Interest = Principal x Rate x Time

In the Simple Interest Universe, this formula calculates the amount of money that has migrated together (Interest) from a static Principal pile over Time due to the weak gravitational pull of interest (Rate).

Compound Interest Formula:
A = P(1 + r/n)^(nt)

In the Compound Interest Universe, this formula measures the total Amount (A) that results from multiple generations of money spontaneously splitting and multiplying (1 + r/n)^(nt) from the original Principal (P) over Time (t).

Annuity Formula:
Present Value = Payment [1 – (1 + i)^-n] / i

In the Annuity Universe, this formula determines the current value of an agreement (Present Value) to receive regular pulsating Payment waves over n intervals, factoring in the modulating effect of additional contributions reinforcing the waves’ Harmonic frequency according to the annuity interest Rate (i).

I hope these recasts of the interest and annuity formulas within their respective imagined settings were engaging and conveyed a sense of the concepts in a novel, more relatable way! Please let me know if any part needs more clarification or description.
