Widdershins Podcast

In part 2 of our two-part series we are joined this week by Caroline Mallary a PhD student at the University of Massachusettes and our past guest Dr Gaurav Khanna from Episode 1 on Hyperspace. This episode is more focussed on time travel where last week's episode we dove right into time loops. Caroline Mallary has discovered that her time machine, although in its simplest form, does not need exotic matter... matter once thought to be required if a time machine was ever to be built.

In part 1 of our two part series we are joined this week by Caroline Mallary a PhD student at the University of Massachusettes and our past guest Dr Gaurav Khanna from Episode 1 on Hyperspace. The theory of time travel and time loops we discuss require two long spaceships parked in parallel. One moves forward really fast, while the other is parked. Caroline explains that a time loop forms between the two cars such that space and time folds on itself. Although almost impossible to create and imagine right now, the science is now here and we have just witnessed another breakthrough in space-time.

This week on our debut episode I discuss Hyperspace with Dr Gaurav Khanna www.linkedin.com/in/gaurav-khanna a Professor in the Physics Department, and the Associate Director of the Center for Scientific Computing at the University of Massachusetts Dartmouth. He works on a variety of challenging problems in theoretical and computational physics. Dr Gaurav introduces me to hyperspace and blackholes and as a non-scientist (although learning everyday) I learn very quickly that in theory travel through a blackhole won't necessarily be dangerous at all. In fact science indicates the 'Yes' if you have a large enough blackhole and if it is spinning fast enough then travel through would be safe and that the main issue is what is on the other side of the singularity?Further Reading and Resources:Life of the Cosmos's written by Lee Smolin: https://www.bookdepository.com/Life-Cosmos-Lee-Smolin/9780195126648?ref=grid-view&qid=1574913237375&sr=1-6&a_aid=widdershins&a_bid=ba35a05bRotating black holes may serve as gentle portals for hyperspace travel: http://theconversation.com/rotating-black-holes-may-serve-as-gentle-portals-for-hyperspace-travel-107062This episode was inspired by the book: The Hyperspace Trap - Christopher G Nuttall https://widdershinspodcast.com/season-one%3A-space-1See more from Dr Gaurav Khanna at: http://gravity.phy.umassd.eduFollow Widdershins and please Rate and Review us in your favourite Podcast app so others can easily find Widdershins!Visit our website: www.widdershinspodcast.com/ for member only access and merchandiseFacebook: www.facebook.com/WiddershinsPodcast/Twitter: https://twitter.com/WiddershinsPInstagram: https://www.instagram.com/widdershins_podcast/Email us: connect@widdershinspodcast.comWiddershins proudly uses the services of Letitia Stafford – The Ultimate Podcasting Virtual Assistant

This week on our Bonus episode I discuss Future Weapons with Skeeve Stevens www.linkedin.com/in/skeeve/?originalSubdomain=au. Skeeve was the first Australian to be imprisoned for hacking. He is a Futurist, entrepreneur, keynote speaker, technology architect, consultant and visionary in number of areas including: Futurism, Network Architecture, Cloud Infrastructure, Advisor in Future Technology Crime and Critical Infrastructure Protection, Virtual & Augmented Reality, Internet of Things, NFC/RFID, Personal/Commercial and Security Robotics, Smart Cities, Consumer Behaviour and Psychology, Trend Analysis and Technology based Neuroscience aka Brainwear.The conversation with Skeeve is an intense one and not only due to the nature of weapons as a topic but also due to the reality that strikes like a slap in the face when we uncover just how easy it is to take everyday electronics, including toys and convert them into weaponry. The future is a reoccurring theme in my chat with Skeeve and although the dark shadow of children as weapons and super humans taking our jobs is high on our radar, Skeeve assures me micro-chipping, human upgrade and smart drugs will be an ordinary feature in the lives of everyday people in the very near future.Further Reading and Resources:Wikileaks - Hilary Clinton: https://wikileaks.org/clinton-emails/emailid/25404This episode was inspired by the book: Ghost Fleet - P.W.
