Gravity is one of the fundamental forces of nature, its invisible grip governing our planet – from the rocks inside to the seas on the surface. In this edition of Space, we begin our adventure in a massive cave in northern Italy, a space beneath the surface of the Earth that is so big it has an effect on the local gravity field. If you parked a car weighing one tonne above this cave, it would weigh five grammes less than elsewhere.
Our culture, and our skies, are full of rainbows, but do you know how they form? Do we all see the same rainbow?
Is it in the Arctic Ocean? In Canada? Russia?
Life is chaos and the universe tends toward disorder. But why? If you think about it, there are only a few ways for things to be arranged in an organized manner, but there are nearly infinite other ways for those same things to be arranged.
Can we really touch things? Well if by touch we mean exchange a force-carrying particle with, then yes. The photon is the force-carrier of the electromagnetic interaction. But if the photon is also a particle of light then why aren’t magnets glowing? Because the photons are virtual particles, which means they can’t be directly detected (without changing the outcome we are trying to measure.
In the video these beads seem to levitate, defy gravity and jump out of the beaker. But how and why do they act like this? Steve Mould, the science guy from Britain’s Brightest, explains the science behind the “self siphoning beads” – also known as “Newton’s Beads.”
How does a gas operated rifle work when filled with water?
I’ve already shot the second video. It’s awesome. I recommend subscribing. I put more brainpower into it the second time so you won’t be disapointed.
New research on the physics of mosh pits. Discussed by Professor Phil Moriarty.
Energy is like the bestest best friend ever and yet, most of the time we take it for granted. Hank feels bad for our friend and wants us to learn more about it so that we can understand what it’s trying to tell us – like that any bond between two atoms contains energy. How much energy? That’s not the simplest question to answer, but today Hank will answer it (kinda), by teaching us about a nifty little thing called enthalpy.
Prof. Morello explains why spin does not mean the particle is actually spinning. Subatomic particles like the electron, neutron, and proton have spin, which means they act like tiny bar magnets. This can be used in quantum computing applications.
Grumpy Professor Hank admits to being wrong about how everything is chemicals. But he now wants you to listen as he blows your mind with a new sweeping statement: everything (yes, really everything this time) is energy. What?!
This week, Hank takes us on a quick tour of how thermodynamics is applied in chemistry using his toy trebuchet as an example, because he is a proud nerd.
Why is that some experiences feel like they last forever, while others fly by? We tend to miscalculate the time it takes to engage in novel activities due to the influence of memories. Matt Danzico explains why your childhood feels like it lasted forever and why that beach vacation seemed like two months rather than two weeks.

Which came first, the chicken or the egg? Scientists figured the answers to this and other pressing questions once and for all.
