Listen Later

Prepare to have your curiosity catapulted to cosmic proportions in this enthralling Q&A edition of Space Nuts, where our intrepid hosts Andrew Dunkley and Professor Fred Watson delve into the gravitational enigmas and hypotheticals of the universe.
Firstly, Bo from Melbourne brings us a mind-bending question about the Big Bang and gravitational waves. Could the universe's colossal birth have sent ripples through the fabric of spacetime? Fred unpacks the complexities of detecting such ancient cosmic echoes and explores the tantalizing links to the cosmic microwave background radiation.
Next, Rennie from sunny West Hills, California, presents a tantalizing 'what if' scenario: What if the Sun never died? Would Earth eventually succumb to its own demise? Our dynamic duo contemplates the slow dance of celestial mechanics, the potential for human adaptability, and the intriguing future of a planet with a 42-day-long day.
Lastly, Daniel from Adelaide ponders a cosmic conundrum where time and dark energy might intertwine. As he questions the nature of the universe's accelerated expansion and the role of dark energy, Fred provides a nuanced response that sifts through the layers of cosmological understanding.
With each query, Andrew and Fred traverse the vastness of space, time, and possibility, offering insights that will leave you pondering long after the episode ends.
