According to our current understanding of physics, particles with mass cannot pass through solid walls. This concept is based on the fundamental principles of quantum mechanics and the properties of matter.
In quantum mechanics, particles are described by wave functions that determine their behavior and probabilities of being in different states. When a particle encounters a potential barrier, such as a solid wall, the wave function of the particle interacts with the barrier. This interaction leads to a phenomenon called quantum tunneling.
Quantum tunneling allows particles to pass through barriers that would be classically forbidden. However, the probability of tunneling decreases exponentially with the thickness and height of the barrier. For macroscopic objects like solid walls, the probability of a particle tunneling through is essentially negligible.
The reason we don't observe everyday objects spontaneously passing through walls is due to the extremely low probability of such events occurring. On the microscopic scale, where quantum effects dominate, particles can exhibit tunneling behavior, but this behavior is not observable at macroscopic scales.
It's important to note that there are still many mysteries and open questions in physics, and our understanding may evolve with further research. However, as of now, particles with mass, such as atoms or subatomic particles, do not pass through solid walls in the way depicted in science fiction or popular imagination.
