46:49Now PlayingCan you make something invisible? Neil deGrasse Tyson and comedian Negin Farsad discover the science behind invisibility with professor of physics and optical science, Greg Gbur. What would real-life invisibility look like?
Can you be invisible in other parts of the magnetic spectrum? We discuss transparency versus invisibility and how metamaterials help us interact with different wavelengths. What does light have to do in order to make something invisible? We break down invisibility cloaks and other invisibility devices from fiction.
Could you make yourself invisible to all parts of the electromagnetic spectrum? We explore the main challenges in achieving invisibility and the difference between passive and active invisibility. How useful of a power would it be?
We discuss the interaction between waves and matter. What makes some waves reflect off matter and others pass through? Learn about x rays and how they work, plus, an at-home invisibility trick using prisms. Finally, could you make someone invisible to time?
