What is radio astronomy? How big is going to be the next generation radio telescope? What is SKA? This is the first episode of a weekly podcast about the fascinating world of astronomy. On today’s episodio I have a conversation with Phil Diamond, who is the Director General of the Square Kilometre Array, we talk about the science behind this telescope, from the original idea to where they are today. Are we going to prove Einstein wrong? How are we going to be able to see the early universe? All of that and so much more on this first episodio of Astronomy et al.
