Today we’re going to delve into a couple of the most famous paradoxes of special relativity: the Twin Paradox, The Ladder Paradox (aka the Barn-Pole Paradox), and a paradox suggested by our very own viewers, […]

Erratum: Figures in the episode should be Minev et al. (2019), not Minney et al. (2009). Our apologies to the authors! This is the experiment we talk about: To Catch and Reverse a Quantum Jump […]

We often think of quantum mechanics as only affecting only the smallest scales of reality, with classical reality taking over at some intermediate level. But in his 1944 book, What is Life?, the quantum physicist […]

Good news everyone: it looks like the universe is going to end with a series of catastrophic explosions. The very, very long story short is that the universe ends in heat death, as it approaches […]

Physicists have a long history of sticking our noses where they don’t belong – and one of our favorite places to step beyond our expertise is the question of consciousness and free will. Sometimes our […]

The Nobel prize in physics this year went to black holes. Generally speaking. Specifically, it was shared by the astronomers who revealed to us the Milky Way’s central black hole and by Roger Penrose, who […]

Einstein’s special theory of relativity combines space and time into one dynamic, unified entity – spacetime. But if time is connected to space, could the universe be anything but deterministic? And does that mean that […]

If you rank the most habitable places in our solar system Venus lands pretty low, with surface temperatures hot enough to melt lead and sulphuric acid rain. And yet it may have just jumped to […]

With the global pandemic of COVID 19 still encompassing the word, we are generally not big fans of viruses right now. But we sure are thinking about them a lot. That’s right, even astrophysicists are […]
