The holy grail of theoretical physics is to come up with a quantum theory of gravity. But after a century of trying we really have no idea how close we are, or it it's even possible. But we shouldn't feel bad because it turns out that...

Every time you walk out the door, light from the Big Bang strikes your face, enters your eyes. This is the cosmic microwave background radiation - the left-over heat-glow from the very early universe. We can’t see this microwave light...

What is Quintessence? Well we know that something is up with the way the universe is expanding - there’s some kind of anti-gravitational effect that’s causing the expansion to accelerate. We don’t know what it is - just that it competes...

Every astronomy textbook tells us that soon after the Big Bang, there was a period of exponentially accelerating expansion called cosmic inflation. In a tiny fraction of a second, inflationary expansion multiplied the size of the...

The universe is expanding, and that expansion is accelerating. We don’t know what’s causing that acceleration, but that hasn’t stopped us from giving it a name. We call this unknown influence dark energy. The observed acceleration is,...

Improving batteries is a tough problem, but it’s also an important one because in many ways the future of our planet also depends on the future of batteries. Luckily, scientists are on the case, figuring out ways to give this essential...

We've come a long way in our understanding of dark energy. In previous episodes we've looked at how our universe is paradoxically flat and how dark energy is exponentially accelerating the expansion of the universe. Now, let's dive into...

Let's talk about the mysterious zero-point energy and what it really can, and really can't do.

Clean, renewable energy is becoming more and more common in our everyday lives. But, as our cars and buildings become more green, tens of thousands of airplanes fly every day using petroleum-based fuel, and there's seemingly no end in...

If vacuum energy really does have the enormous value predicted by quantum field theory then our gently expanding, geometrically flat universe shouldn't exist. This is the vacuum catastrophe.

In this wide-ranging, thought-provoking talk, Kevin Kelly muses on what technology means in our lives -- from its impact at the personal level to its place in the cosmos.

In the early 1800s, Michael Faraday showed us how a changing magnetic field induces an electromotive force, or emf, resulting in an electric current. He also found that electric fields sometimes act like magnetic fields, and developed...

The shape, contents and future of the universe are all intricately related. We know that it's mostly flat; we know that it's made up of baryonic matter (like stars and planets), but mostly dark matter and dark energy; and we know that...

Improving batteries is a tough problem, but it’s also an important one because in many ways the future of our planet also depends on the future of batteries. Luckily, scientists are on the case, figuring out ways to give this essential...

It’s hard to replace jet fuel because the alternatives aren’t energetic enough, are too dangerous, or aren’t yet being made at scale.

So, how do those defibrillators you see on TV actually work? Surprise! Physics can explain! Okay buckle up, everyone! Today, Shini has the task of breaking down Electrical Potential Energy, Electric Potential, Voltage, Capacitors, Energy...

It’s one of the biggest mysteries in science. It makes up the majority of the universe. What is dark energy? What is dark energy made of? What is quintessence? Is Dark energy the cosmological constant?...

SUMMARY

The law of energy conservation may be the most fundamental law in physics. It says that overall energy is always conserved. It can never be created nor destroyed - it can only change form. But this law...
