17 September
Australian moral philosopher, Professor of Bioethics emeritus at Princeton University; author of Animal Liberation, Practical Ethics and The Life You Can Save.
In this episode of Lives Well Lived, we speak with physicist and philosopher @seanmcarroll.bsky.social about the many-worlds interpretation of quantum mechanics, the mystery of consciousness, whether morality is constructed, and how we create meaning in a universe without an objective purpose.

Almost every technology boom creates a bubble, then a bust, whether it’s railroads, the Industrial Revolution, or the late 1920s. Think about the late '20s: electricity, refrigeration, telephones, radios, airplanes, and cars were all emerging at once. Naturally, people wanted to invest in these miracles. The danger is that people fail to distinguish the miracle from the investment. A technology can be truly transformative, but if the stocks are priced too high or bought on debt, you get a crash. That is the mechanics behind how bubbles form and burst. New technology will be great, there is no… energy Related
Physicist and science communicator. Writes Backreaction and makes videos explaining new physics and astronomy results, frequently to argue that the headline about them overstates the case.
Physicists should put together a list of mathematically well-defined problems that could advance the field. Such as, eg, what constitutes a low-temperature superconductor, what are the lattice conditions for cold fusion (or why do they not exist), what is a local completion of quantum mechanics, what is the simplest (in terms of computational complexity) way to obtain the masses and coupling constants of the standard model, what is the UV-completion of MOND or why isn't there any, is there any provably UV-finite version of quantum gravity, etc etc Related

But I have faith that we've been doing this for centuries and we've made progress before. There's no reason why we should stop.

Astrophysicist at Barnard College; wrote Black Hole Blues and How the Universe Got Its Spots, and directs sciences at Pioneer Works.
Their words
I’m unhappy with that. I would not be happy with information loss. I love that it’s telling us that there’s this crisis because I do think it’s giving us the clues, and we have to take them seriously.

what is it that creates true virality? It's not viral mechanics. It's word of mouth. It is brand that this is how you can kickstart a brand.

Astrophysicist at the University of Rochester; works on the search for life elsewhere and wrote The Little Book of Aliens and Light of the Stars.
Their words
Many of them try to pretend the measurement problem isn't there. Go to enormous lengths like the many-worlds interpretation, literally inventing an infinite number of unobservable parallel universes to avoid the thing that quantum mechanics is telling them, which is that measurements matter.

Their words
If you think about how we teach quantum mechanics to our students, the Copenhagen interpretation, it’s a God-awful mess. No one’s going to accuse that of being very beautiful. I’m a fan of the many-worlds interpretation of quantum mechanics, and that is very beautiful in the sense that fewer ingredients, just one equation, and it could cover everything in the world.

Their words
I think that that story about the latter part is completely wrong, almost 180 degrees wrong. I think that Einstein understood quantum mechanics as well as anyone, at least up through the 1930s. I think that his philosophical objections to it are correct. He should actually have been taken much more seriously about that.

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
