Always love hearing from Professor Copeland! 😎

[silverbiocide]

I just want to have a beer 🍺 with Professor Copeland after a lecture!

[davelister]

You can't just end it there! Where's the extra footage, to the extra footage?

[acetate]

"There were only 20 people at the lecture..."

Amazing. I wish I could go back and sit in some of these lectures by the greatest minds of the 20th century. Bohm being a particular person of interest who doesn't get the credit he deserves when talking about the people who've done groundbreaking work that contributed to our understanding of the world.

[DrTopaz]

Ed is such a calm, sensible and composed story teller. I could listen to this man talk for 40 years and it would seem less ephemeral than the time it takes to microwave a frozen burrito.

[IuliusPsicofactum]

It all make sense now. You are entangled with David Bohm! Cause you measured him at that lecture.

[gavinlangley]

What evidence exists that entanglement persists over distance, large distances? There is this statement about entanglement that we have to take as a given. Then we have these extrapolations about the meaning of that. Do we really understand the nature of entanglement? I never get a sense of it. It would be great if you could cover what we know about entanglement in detail over and above those basic statements. What if entanglement breaks in some way given sufficient distances and/or speeds I doubt that it is a relationship that spans all space and time. That would be very odd.

Can you please do a video on exactly how you go about making entangled particles? NO ONE has done one that i'm aware of. No one actually describes an actual experiment in simple terms and explains how you know it will work from "millions" of miles away? Thank you.

[gaborszeleczki]

If there would be a crowdfunding project to make an at least 10 hours long video series with Prof. Copeland, which would be like a 101-level cosmology/particle physics class, I'd definitely back it up

[yourfaceisonfire]

The long form extras with Ed are what I play to fall asleep to. Love em. Know all about the big rip/super strings/inflation

[PhilFogle]

In 1974, I did a course on Special Relativity at Birkbeck, and my teacher was David Bohm. He would sit with us in the common room at tea-break. What a great man!

[TheyCallMeNewb]

And of course Ed has a personal connection to the case. !

[MrSpeedyAce]

Professor Copeland has such a soothing lecture voice 🙂

[AB-whpo]

I could listen to Prof Copeland reading the back of a shampoo bottle! Such a great voice and what an interesting man to back it up!

[Systox]

This is mind blowing
1982 is 40 years ago

[deborahcoyle]

Awesome story! Thanks for sharing, professor.

[eugenmin]

entanglement makes two particle to share a quanta of spacetime?

[MelindaGreen]

Could the spooky paradox be resolved if entangled particles aren't independent objects but a single object with two different aspects, like the two faces of a coin? It seems absurd to have a coin that's potentially millions of miles thick, but perhaps we're just not thinking about space correctly. We're used to the idea of wormholes which are a bit like this, so maybe entangled particles inhabit a far more interconnected space than we can currently detect. If so, then measuring a particle and discovering it's twin's property immediately isn't more surprising than looking at one side of a coin and instantly knowing what's on the other side.

[BebopSpeaks]

Entangled particles, when they are separated, create a "private" conduit between them, outside space-time (wherever that is), that allows them to maintain instantaneous communication without breaking the laws of physics. Of course, no way to prove or disprove this idea.

[erikeriknorman]

Quantum entanglement is just objective bias being shy. The Nobel Prize has wildly contradictory standards
