Neil deGrasse Tyson guides us through a photon's journey across space, time, and mind in this full-immersion planetarium program. Follow its journey as it is produced in a distant star and then travels the vast distance of space to be focused on someone's retina. The photon's journey is completed when it's energy is converted into an electro-chemical impulse that then travels the neuro pathways of the brain which create the image the mind sees. This fulldome planetarium show explores some of the fascinating processes of the cosmos, from astrophysics to the biology of the eye and brain.
