About the Talk:
Echoes from the Past
According to current observations, the universe may contain at least a hundred billion galaxies grouped in vast shell-like structures that surround immense expanses of space. In this talk, Dr. Prosper follows a line of reasoning that leads to an astonishing conclusion: that these immense cosmic structures are the echos of ripples in space and time that occurred 14 billion years ago.

About TEDx: x = independently organized event
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized. (Subject to certain rules and regulations.)
