Supersonic jets like the Concorde face concerns over safety, high carbon output, and cost. They also make loud sonic booms so loud that only transoceanic flights are legal. Now one NASA program is trying to make a quiet supersonic plane...

That asteroid the headlines have been warning people about isn't likely to actually hit us, and scientists might have solved a mystery that could save lives: the relationship between tides and earthquakes.

Hank tells you about cavitation - the power of tiny bubbles to weaken metal, kill fish & maybe even cure cancer.

It used to be that you could get on a Concorde jet and fly across the Atlantic ocean faster than the speed of sound, but what does the future hold for supersonic flight?

Breaking the bottom out of a glass bottle by hitting the top is a challenging trick, but involves a ton of physics. The explanation is related to cavitation - a process seen in the Mantis Shrimp attack, head injuries and pouring honey!
