Proving the impossibility of physical movement, based on the Assumptions of modern science. This proof, based on the assumptions of modern science and medicine, reveals how we are unable to move our bodies even for the simplest of tasks, such as blinking an eye, or lifting a finger.

1. A person chooses to begin walking. Neurons fire in his/her head, thus initiating electrical pulses sufficient to cause the relevant muscles to work the process of physical movement.
2. Prior to the first signal being sent, a neuron is required to fire (note, see Scientific Assumptions identified earlier).
3. Prior to this first neuron firing, sufficient electrical charge (potential difference) must be accumulated in order to fire the neuron - for the signal to leap the synapse.
4. However, the building of electrical potential cannot be caused by the choice of walking itself, as it is the first neuron ("thought"/"feeling") in the chain of electrical signals sent to the muscles.
5. Since, according to the Scientific Assumptions (see above), all physical movement originates with neurological activity (firing of neurons), there cannot be a neurological "first thought" or a "first feeling" associated with the choice to walk, as there is no cause of the building of electrical potential sufficient to enable the required neurological processes of "thinking" and "feeling", and the subsequent experience of walking.
6. Ipso facto, physical movement, based on the identified Scientific Assumptions as defined, is impossible.
