The Arecibo Message and Interstellar Communication Nov 27, 2025

Show notes

What happens when humanity dares to shout a cosmic “hello”? Could it help alien civilisations decode human mathematics, our DNA, the blueprints of who we are? And why did we blast the 3-trillion-watt message into the stars in the first place…only to never try anything like it again?

This is the story of the Arecibo message.

Welcome to The Rest Is Science: Field Notes.

Every Thursday, Hannah and Michael rummage through their personal troves of scientific treasure and source discoveries that explain our understanding the universe, oddities that scramble our brains, objects that hint at forces we’ll never see...and a few things that are essentially just plain cool.

Expect deep dives into the science behind each pick, the spark that grabbed their attentions, and the sheer delight they get from sharing it all with you.
They’ll also be tackling your questions, so email The Rest Is Science at therestisscience@goalhanger.com.

The Physics of Gravity Nov 25, 2025

Show notes

What is gravity, really? Why do objects pull towards each other at all? And if Einstein 'fixed' Newton’s theory, why does gravity remain one of science’s biggest unsolved mysteries?

A clumsy trip into a lamppost leads Michael and Hannah into a whirlwind tour of our changing understanding of gravity, from falling apples and making wormholes for ants, to the puzzles we still can’t crack.

Why does time tick faster on a mountaintop than by the sea? Why are galaxies spinning in ways our equations can’t explain? And could an invisible particle finally reveal what gravity is made of?

Join Professor Hannah Fry and YouTube educator Michael Stevens as they uncover the strange, unfinished story of the force that holds the universe together.

How To Drink Lava Nov 25, 2025

Show notes

Is lava water, and could we have a delicious hot cup of it? Is ice really a rock, and not water? And, the age old question, is water wet?

From the minerals that shape the taste of our favourite drinks, to the tiny isotopes that reveal where a person, or whale, has travelled, Professor Hannah Fry and Michael Stevens reveal the hidden life of H₂O.

Along the way, they uncover why pure water can be deadly, how yesterday’s sewage might be fuelling the future, and discover that the water in your glass might be older than the Sun.

Prepare to rethink the world’s most familiar liquid - it’s far stranger, rarer, and more extraordinary than you ever imagined.
