She was inspired to delve a lot deeper after “accidentally” attending a lecture on cosmology at the University of Sydney one summer, saying “it blew my 17-year-old brain out of the water”. She was always fascinated by the stars, but the idea of spending her life studying them didn’t occur to her until she was in her final year of high school. Professor Rachel Webster is one astrophysicist trying to solve the mystery of what came before the formation of the very first stars. But can those discoveries tell us more about what came before them? Starry, starry nights In recent years, we’ve started to learn a lot more about those very first stars thanks to advances in the technologies and techniques we use to study the Universe. Our Universe went through several different stages of development. This period of time is known as the Cosmic Dark Ages for two reasons: figuratively, because scientists know very little about what was taking place in the Universe at that time, but also quite literally, because there were no stars providing light. We can still detect the after-effects of these early moments in the cosmic microwave background.īut then, the Universe went dark. ![]() ![]() Our Universe had a violent start, kicking off with that famous Big Bang and a blazingly hot cosmic ‘soup’ of sub-atomic particles scattering light in all directions. Not surprisingly, things that are further away require more advanced instruments to measure them and we need clever ways to make sense of the data collected. Light takes time to travel through the vast distances of our Universe, so when we see objects that are further away we are seeing what they were like further back in time. In a way, travelling back in time is something that astronomers, astrophysicists and space scientists do every day when they look into space. If only it were possible to travel back through time to witness the start of everything … “… we’re slowly finding more ways to pull back the curtain and peer into those times.” Pondering our origins has captivated scientists, philosophers and storytellers for millennia, all trying to understand those first precious moments in the beginning-and how humans eventually arrived on the scene, too. Sinus infection spreading to optic nerve I can taste/smell things that's aren't there Sudden onset of flashing lights in peripheral vision in dark situations.There aren’t too many questions bigger than how our Universe came into existence.
