This week on Afraid to Ask, our question comes from listener Rosie, who wants to know if humans will ever get to the stars. Will physics or biology have to change?

To answer her question, we chat to Professor Sergei Gulyaev and Dr. Jordan Alexander, AUT's space experts, about worlds beyond our own, and how likely we are to ever see them.

Let us know what you think, and don’t forget to submit your question at #askAUT
