Lecture series:- The Gravitus of Gravity and why matter matters 
Lecture :- Gravity at the Limits 
 
Astronomy is a fascinating subject studying all extraterrestrial objects and phenomena. In this public lecture series, some stunning astronomical phenomena including planetary nebulae, supernova explosions, black holes, neutron stars and cosmic web will be introduced. Participants will be amazed by the complexity and beautiful objects up above our sky. 
 
Gravity is the most important force governing the structure of the Universe. In this talk the speaker will introduce gravity related phenomena under the most extreme and violent conditions in the Universe, from supernova explosions to neutron stars and black holes. When a massive star runs out of fuel, it can no longer support itself against gravity. This results in core collapse, inducing a supernova explosion. The compact core left over becomes either a neutron star or a black hole. These compact objects have ultra strong gravity, which causes some interesting effects that can never be produced on Earth.
