What if the version of the Big Bang we were taught in school isn't what physicists actually believe?
We’ve all heard the story: the universe exploded into existence out of absolutely nothing. But according to a massive survey of top physicists, 68% agree that the Big Bang wasn't necessarily the definitive beginning of time, but simply a phase when our universe was incredibly hot and dense. So, what actually happened before our cosmic clock started ticking?
Join Jeroen Schreel and Niayesh Afshordi, a Professor of physics and astronomy at the University of Waterloo, and research associate faculty at Perimeter Institute as they deconstruct the modern definition of the Big Bang, shifting away from the idea of a mathematical "singularity" where time stops, and looking at it like waking up from a cosmic dream. From cosmic inflation and primordial sound waves to mind-bending alternative models, like a cyclical "Big Bounce" or the hypothesis that our 3D reality emerged from a collapsing 5D star, this episode bridges the gap between popular myth and cutting-edge physics.

Is the traditional literature review dead? In an era where AI can summarize 1,000 papers in seconds, the boundary between "working smart" and "losing depth" has never been thinner.
As researchers, we are facing a fundamental shift: AI is no longer a futuristic concept—it is a pervasive reality that touches every domain of science. But as we automate our workflows, are we sacrificing the very creativity and learning curves that define a PhD?
In this episode, Jeroen Schreel sits down with Faheem Ullah, an Assistant Professor in Computer Science at the University of Adelaide, to dismantle the hype and provide a technical roadmap for the modern academic. Faheem breaks down the hierarchical differences between AI, Machine Learning, and Deep Learning, while offering a pragmatic framework for using these tools without compromising your academic integrity.
We dive deep into:
- The 1-Hour Literature Review: How to turn a week-long manual search into a high-productivity hour using iterative search strings and pilot studies.
- The Technical "Black Box": Understanding feature selection, hyperparameters, and why Deep Learning is uniquely suited for automation.
- The Cost of "Free" AI: Why experts predict a jump to $100/month subscriptions as data center costs explode to $600 billion.
- The Hidden Biases: A cautionary tale on how AI-generated avatars and data logging can introduce unintended gender and academic bias.

Are you being tricked by "Zero Sugar" labels and "healthy" processed snacks that are actually destroying your metabolism?
Join Jeroen Schreel and Andrew Koutnik, a research scientist at Florida State University, as they delve into the science behind nutrition and obesity, and the metabolic "landmines" waiting for you in every grocery store. From his personal journey of overcoming childhood obesity to receiving a life-changing Type 1 Diabetes diagnosis at age 16, Andrew shares how he turned a chronic disease into a scientific asset to uncover the truth about human health.
He explains:
