This video shows an animation complementing Figure 1 of the article. It shows a scalar wave with a wavelength ten times smaller than the Schwarzschild radius as it approaches the event horizon (x=1) of a Schwarzschild black hole, as seen from infinity. As expected, the wave is seen to "stop" before it reaches the horizon. This occurs because the physical description is made from the point of view of an observer located at an infinite distance from the hole.

This video shows an animation complementing Figure 2 of the article. The simulation shows a scalar wave approaching the event horizon of a Schwarzschild black hole. The wavelength of the wave is 10 times the Schwarzschild radius. The main point of the simulation is to show how the wave bounces off the hole before reaching the event horizon located at x=1. Note that it could be possible that a certain amount of energy from the wave goes through the event horizon, but it is difficult to follow numerically within the 99% accuracy of the numerical precision.

This video shows an animation complementing Figure 2 of the article. It is a 3D cartoon representing all details of the previous simulation. A 2D angle sweep of the 1D simulation along the azimuthal direction has been done in order to produce the animation.
