Great Moments In Science - With Dr Karl Kruszelnicki

Why exactly do we hiccup? Is there a cure!?

How can relativity and quantum mechanics create mass in a tiny particle?

The Universe is made of atoms — but what are atoms made of?

Have we finally figured out how wombats make cube-shaped poo!?

The answer to this question is a little surprising, not least because it involves wee.

Astronomers have seen stars and superhot gas flying in orbits that bring them very close to the supermassive black hole in the middle of our galaxy — and this has taught us a huge amount about the nature of black holes.

Black holes have no size, but have a huge mass — and there's an enormous one right in the middle of our galaxy.

Are you accidentally sharing your precise location, whenever you upload a photo?

Reckon you could measure the circumference of the Earth using just a stick and some basic geometry?

You've probably heard cigarettes are bad for you — but did you know tobacco contains radioactive material?

It's said that the 'alkaline diet' can help you lose weight, and fight off cancer — but it looks like these claims don't stand up.

After hearing about the Parker Solar Probe's mission to the Sun, now Dr Karl is taking a closer look at how it'll survive this fiery journey.

There's still a lot we don't know about the burning ball of gas that sustains life on Earth — but the Parker Solar Probe could help.

For some snapping spaghetti is sacrilege — but for others it’s science.

From spaghetti strands to trees to nanotubes — we need to know about the physics of rod-like structures.

Many of us have microphones in our homes, attached to smart phones and personal assistant devices.

Our bodies are a marvel of sophisticated engineering — almost without exception.

DNA can help us work out family trees, catch bad guys ... and now as a tool in emergency medicine.

Hint: the loneliest ATM is in a very, very cold place.

Plunking yourself into a bath fairly full with water makes the water level rise — and overflow. What about ships and the ocean?
