And today we’ll explore the origin of this effect. And ultimately, we’ll use what we learn to understand how curvature in time - this gradient of time dilation - can be thought of as the true source of the force of gravity. #space​ #generalrelativity #einsteinCheck out the Space Time Merch Storehttps://pbsspacetime.comSign up for the mailing list to get episode notifications and hear special announcements!https://mailchi.mp/1a6eb8f2717d/spacetimeHosted by Matt O'DowdWritten by Matt O'Dowd Graphics by Leonardo Scholzer, Yago Ballarini, Pedro Osinski, Adriano Leal and Stephanie FariaDirected by Andrew KornhaberAssistant Producer: Setare GholipourExecutive Producers: Eric Brown and Andrew KornhaberEnd Credits Music by J.R.S.

But at this stage, it’s all we can do to convince ourselves of their existence. Actually studying the physics of real black holes is much, much harder. I mean, we could try to make one - but that’s way beyond our current tech level, and also potentially humanity-destroying. Well it turns out we don’t need to make real black holes to at least get started with the lab work. We can instead study analog black holes - and by analog, I don’t mean old fashioned clockwork black holes - I mean analogies. Physical systems that aren’t black holes but that behave in similar ways - and may reveal the real behaviours of real black holes.End Credits Music by J.R.S.

In fact if we want the first we’ll need the latter. And the first step to the quantum internet is quantum cryptography.Check out the new Space Time Merch Store!https://pbsspacetime.com/Support Space Time on Patreonhttps://www.patreon.com/pbsspacetimeNeed a Black Hole Refresherhttps://youtu.be/vNaEBbFbvcY#cryptography #quantumcomputing #spacetimeHosted by Matt O'DowdWritten by Graeme Gossel and Matt O'DowdGraphics by Leonardo WilleDirected by Andrew KornhaberProduced By: Kornhaber BrownQuantum theory may seem like an obscure subject of questionable relevance to the average person. But in fact much of our technological world depends on our understanding of the quantum properties of the subatomic universe. And soon, perhaps very soon, we’ll be interacting with the weirdness of quantum mechanics even more directly – with the coming of quantum computing and the quantum internet. Quantum computing is a topic that’s that has been well covered, so we’re going to be talking about the quantum internet. Specifically quantum cryptography and quantum key distribution – the foundations of the prospective quantum internet. We may come back to quantum computer in detail – but for now let me show you why their advent will demand a quantum internet.

The entropy of the universe must always increase – so says the second law of thermodynamics. It’s a law that seems emergent from deeper laws – it’s statistical in nature – and yet may ultimately be more fundamental and unavoidable than any other law of physics.
