Stephen Wolfram answers audience questions about physics and astronomy as part of an ongoing livestream Q&A series for kids (and others).
Questions include: Is it possible to communicate with worlds outside our solar system? - Is it possible to make a suit that can make you grow and shrink at will like in Ant-Man? - How does a satellite stay in orbit around the earth (or a planet stay in orbit around the sun)? - Could we access other dimensions? - What are protons, neutrons, and electrons made of? - If neutron stars are just neutrons, how come they produce light? - How do magnets work?
