Black Hole Interior from Loop Quantum Gravity

Figure 2

Plot of the lapse function 𝑁²(𝑡) for 𝑚=10 and 𝛾𝛿∼1 (in the horizontal axis, we have the temporal coordinate 𝑡 and in the vertical axis, we have the lapse function). The red trajectory corresponds to the classical Schwarzschild solution inside the event horizon, and the green trajectory corresponds to the semiclassical solution.
