In this hypothetical universe, the speed of light is proportional to the local gravitational field strength, creating a scenario significantly different from our known physics. Here's a structured analysis of the laser pulse's journey as it approaches a massive black hole:

---

### **1. Speed of Light**
- **Behavior**: As the laser pulse travels from a region of **very weak gravity** (where the gravitational field strength is low) toward the **black hole** (where the gravitational field is extremely strong), the **speed of light increases**. 
- **Reasoning**: The speed of light is explicitly stated to be proportional to the local gravitational field strength (e.g., $ v \propto g $). Thus, in stronger gravitational regions, the pulse's speed becomes higher.

---

### **2. Frequency (Blueshift or Redshift)**
- **Expected Outcome**: The laser pulse experiences a **blueshift** (increase in frequency). 
- **Reasoning**: 
  - In standard general relativity, light moving toward a massive object experiences gravitational **blueshift** because it gains energy (its frequency increases). 
  - In this hypothetical scenario, even though the speed of light changes, the **gravitational potential** (stronger near the black hole) likely still influences the energy of the photon. The frequency would increase as the pulse moves into stronger gravity, analogous to the gravitational blueshift in our universe. 
  - **Wavelength Adjustment**: If the frequency increases, the wavelength $ \lambda $ (from $ v = f \lambda $) would decrease, maintaining consistency with the changing speed of light.

---

### **3. Trajectory (Path Bending)**
- **Expected Outcome**: The laser pulse follows a **curved trajectory**, bending toward the black hole.
- **Reasoning**: 
  - In general relativity, light bends near massive objects due to spacetime curvature. Here, the **speed of light varies with gravity**, so the pulse's path would be influenced by the gradient of the gravitational field. 
  - A stronger gravitational field "slows" the speed of light (in our universe, but here it's the *opposite*—the speed increases). However, the **directional deflection** toward the black hole would still occur, as the gravitational field creates a "gradient" that curves the path. 
  - The exact curvature might differ from standard general relativity, but the pulse would still be **attracted to the black hole**, similar to light bending in strong gravity.

---

### **4. Additional Considerations**
- **Energy and Wavelength**: If the speed of light is higher in stronger gravity, the energy of the photon (if related to $ E = h f $) would increase due to the blueshift. However, the relationship between energy and the variable speed of light is not explicitly defined in this hypothetical, so this remains speculative.
- **Event Horizon**: Near the black hole, the gravitational field strength would become extreme, and the speed of light could theoretically approach arbitrarily high values. However, the pulse might still be captured by the black hole's event horizon if the trajectory is sufficiently deflected, despite its increased speed.

---

### **Summary**
- **Speed**: Increases as the pulse approaches the black hole due to the stronger gravitational field. 
- **Frequency**: Blueshifted (higher frequency) as it enters regions of stronger gravity. 
- **Trajectory**: Curved toward the black hole, consistent with the gravitational influence, though the exact nature of the curvature may differ from standard general relativity.

This scenario highlights how a variable speed of light fundamentally alters the dynamics of light in a gravitational field, leading to unique behavioral patterns distinct from those in our universe.
