Can the universe we observe be just one part of something bigger, the multiverse? Is it possible to move between different universes? When was the last time significant observations and discoveries were made about the structure of the universe? Why haven't the new findings led to significant new theories yet? What is the importance of mathematics in terms of understanding the universe? What can be explained with the help of the theory of relativity and quantum physics, and why has it been difficult to reconcile the two so far? What happens inside a black hole and how are black holes related to relativity and quantum physics? What is a theory of everything and what properties are required for a theory of everything? Is it possible that a theory of everything can be invented? Can artificial intelligence come up with all the theory? Why is it difficult to understand the theory of relativity with common sense and can a person ever understand the fundamental structure of reality? Is the structure of the universe at all such that it could be understood by any intelligent being? Are we living in a simulation and if so is it possible to find out? What is consciousness and is consciousness part of the structure of the universe? What will happen to human consciousness if brain cells are replaced one by one with microcircuits? At what point in evolution has consciousness developed and can a single-celled organism be conscious? What is known about the universe at the present time and on what issues is there a scientific consensus regarding the universe? What happened in the big bang and what are dark matter and dark energy? What is time and what is the relationship between time and entropy, i.e. the degree of disorder? What kind of tools have been used to elucidate the structure of the universe and what significance has the invention of the telescope had on the accumulation of new information? What does it mean to look billions of years back in history with a telescope? How does the speed of light affect how it is possible to sense and observe the universe? Is part of the universe forever beyond human reach? What effect does the accelerating expansion of the universe have on the size of the observable universe and why can the universe expand faster than the speed of light? What kind of phenomenon is entanglement in quantum physics and how do we know that the earth revolves around the sun? Esko Valtaoja, professor emeritus of space astronomy, is a guest in the studio.
