Once you find gravity waves, what's next ? Gold ! The most stable and heavy element we know of lies central to our interpretation of our cosmos. Coincidence ? Dr Karl consults Prof Murphy. https:\\drkarl.com   

The 21st century has been huge for physics. We are now able to build experiments to test Einstein's theories. Professor Tara Murphy has been there and gives Dr Karl an insider's view of modern physics. https:\\drkarl.com  

Resolving subatomic particles in an expanding universe is complex. Can multi-dimensional maths help ? Dr Karl visits Prof. Greene to find out what string theory is and if there are answers. https://drkarl.com https://www.briangreene.org  

Dr Daniel Zarin has spent his career studying and teaching the science of forests. In a conversation recorded at the Wildlife Conservation Society’s Bronx Zoo headquarters in New York City, Zarin tells Dr Karl why he recently left the philanthropic sector to become Executive Director for Forests and Climate at WCS and why trees are the asset we need to revalue today. drkarl.com wcs.org

Viruses. We know where they come from. We know how they spread. Virologist Professor Holmes from Sydney University lays a three-point plan to stop them with Dr Karl.  https://drkarl.com      

We want Cooler climates. Are carbon and coal are burning us up? Economist Dr Denniss runs his ruler over the climate ledger with Dr Karl.  https:\\drkarl.com @RDNS_TAI twitter

Is attention-loss corroding civilisation? When we we fail to comprehend, are we putting ourselves at risk ? Dr Karl sharpens his focus on the research of Johann Hari and his new book 'Stolen Focus'.

The Antikythera Mechanism is a portable planetarium from Ancient Greece. It is 2200 years old and the first known analog computer. Dr. Nick Andronis built one. The front shows the zodiac position of the first 5 planets, sun, moon phase and date. On the back a 72 year lunar and Olympic calendar with solar or lunar ecliplses.  www.amclock.net drkarl.com

2022 looked safe -then it wasn't . Dr Karl investigates with University of Sydney Prof Eddie Holmes. He was the first western source of the Wuhan genome. How could Omicron fool the world?  How can we avoid being fooled again?   

We are counting on an electrified future to cut carbon emissions. Greener futures, as we plan them,  depend on electricity and electro-magnetism. Dr Karl explores the physics of electricity and generators with Professor Lewis. drkarl.com geraintflewis.com

Every week new supplements are announced and promoted. Some can be useful additions to your diet but what about probiotics and prebiotics ?  Dietetics professor Collins explains what they claim, what is in them and if they help.  

Electricity is a great foundation for sustainable energy but Dr Karl discovers how little he knows about the physics of electrons. We all have much to learn about the source of power from Professor Lewis.   drkarl.com geraintflewis.com

What colour is our Sun? (or Sol as local folks call it). How long will it stay that way?  Professor Lewis resumes his fascinating journey in time space and consciousness. We pick up where things are now and go forward to the end. How does it all end? Listen with Dr Karl on this multi-trillion year trip. drkarl.com geraintflewis.com

For some stars, life begins at 10 billion years. Professor Lewis leads Dr Karl on a trillion year expedition from birth to a young adult expanding universe. The first part of a fascinating journey in time, space and consciousness.  drkarl.com geraintflewis.com

Australia has a new Antarctic Vessel. Jono Reeve takes Dr Karl on a virtual tour of the features of the RSV Nuyina.  drkarl.com RSV Nuyina

There were high hopes for the Hubble space telescope. Eventually they were realised with  pictures of galaxies beyond our widest visions. This century the James Webb  promises both time and space with a different universal perspective. Dr Jessica Bloom on why this is a game changer.

The diseases of ageing are already overwhelming health care facilities. In the decades ahead, our older populations will put even more pressure on health unless there are medical breakthroughs. These diseases are proving stubborn to medicate and cures are very rare. A human fountain of youth has yet to show itself. In other animals, things appear easier to treat with less complex biochemistry to get in the way. Dr Bloom explains to Dr Karl why a family of proteins called Sirtuins may hold some hope.

In 1966, two Soviet cosmologists proposed the existence of primordial black holes. 55 years on, evidence mounts that these ancient bodies actually exist. They are the stem cells of the cosmos scattered on a universal matrix and may be pre-atomic. Professor Lewis takes Dr Karl back to the very beginning for an encounter with these dark beasts.drkarl.com geraintflewis.com

A zap from a doorknob or a lightning bolt that sets fire to a forest, these events are notoriously unpredictable. If there is an imbalance of electric charge, a Static Electricity event "might" happen. Things like air humidity or microscopic superficial bumps can play a role – but how much? Professor Lewis explains the known physics and yet-to-be discovered secret life of static electricity with Dr Karl. drkarl.com geraintflewis.com

What happens when a star gets hungry? Could it eat another star? Cosmic cannibalism is a thing. 500 million years ago in a galaxy far, far away – to be precise, about 500 million light years away one of two stars gobbled the other. Professor Lewis explains to Dr Karl the physics and cosmology of devouring your neighbours. drkarl.com geraintflewis.com
