I watched this video AND I didn't watch it.

“ If you are not completely confused by quantum mechanics, you don’t understand it “. — Neil’s Bohr

[darrellainsworth]

What an amazing conversation. Didn’t understand any of it but still great

[roundstone]

Imagining two video games played on the same computer helps me build some intuition around two worlds existing without locations in space.

[a.ginger]

when he said "whats outside of our universe" i said "a bigger turtle!" then at the end he made a turtles all the way down remark 😂 hell yeah

[iamgratitudebecoming]

Love this.

“It just feels suspicious.”
—Lex Fridman
😂❤

Clearly Mr.Carroll is not familiar with a little number known 42.

Many-world is a clever, clean, understandable rational completion of QM. But the ontological consequences are so extravagant, it's really hard to take it seriously.

[mariocasarez]

These guests are very informative compared to your political hacks.

Sean has been my favorite science guy for quite a long time now. Hilariously i found out about him with that William craig debate he did many years ago

[chester-chickfunt]

We need better equipment. Give it 50 years. If we don't destroy ourselves. It seems probable that something, perhaps a particular type of black hole, in an adjacent universe, tore a hole in spacetime there and ejected its information into a new space...our space. An endless cycle. Like a honeycomb.

Sean Carroll is one of my favourite sciencedudes. Mindscape is great podcast

I wonder if the "age of the universe" calculations have included the effects of time dilation. For us, the universe started about 13.8 billion years ago... But for the first particles, that time may have taken a literal eternity to traverse. Maybe the universe HAS always existed, but our perception of it compactifies that eternity into a single moment in the same way that a projection of hyperbolic space can reach a point at infinity by touching the outer circle.

Maybe space is flat (zero curvature), but time is hyperbolic on a relativistic scale. Thoughts?

[ilevitatecs]

The last line was the most important. We can only understand higher concepts based on foundational principles; if the universe is total, there might not be data outside of it to extrapolate why it exists

Hello Lex and Sean.

Once again, this video highlights the problem with Quantum Mechanics and Cosmology today, and that is, physicists are still trying to fit everything with mathematical equations, that are derived from fundamentally flawed conceps of how the atom works, as stated by Sean when he said the way we teach stucdents is a mess,

There is an answer, and it is very simple. Forget the mathematics for a moment, and look at the problem Logically in the first instant.

Forget the Big Bang, and Cosmic Inflation, they are impossible and wrong. The JWST is proving this to be the case.

Forget the idea that the universe began, and consider that it has existed for ever and is infinite.

Forget gravity is due to the curvature of space, this is a nonsense. Gravity is a force, but two forces not one.

Matter was not all formed in one instant, but is undergoing change continuously.


It is the misconception that the universe is expanding that has led to many of the problems in cosmology. I contend that the universe is not expanding: It has no age because it has always existed much as it is now: It will exist forever much as it is now: There was no Big Bang or cosmic inflation: The CMBR is not the afterglow of the big bang, but a point where electromagnetic radiation reaches saturation, and Redshift is not due to the expansion of the universe, but is due to the loss of speed and energy of electromagnetic radiation over distance and time it has travelled.

There has just been published an hypothesis called ' The Two Monopole Particle Universe ' by ' Tony Norman Marsh ', which fully explains all of this Logically. If you type in Tony Norman Marsh into Google, details will be shown.

This hypothesis can also explain Dark Matter, Dark Energy, Antimatter, and two forces of gravity, amongst other things.

If you can provide an email address, I can send you a copy of the manuscript or it can be read instantly on Kindle.

I offer a challenge, look at what I propose and if you do not agree, prove me conclusively wrong. Kind regards,

Tony Marsh.

Always enjoy Sean, but when I hit like I got number 666 Like 🤔

[richinoable]

I like when the YouTube is smarter than me. There should be an application process.

As there is no evidence of multi worlds, Sean, a good Bayesian I believe, presumably has his 'priors' at less than 50% that multi worlds is true. (I vaguely remember him putting it at 40%, but I could be wrong about that.) But he almost always speaks about multi worlds as if he absolutely believes it - I wonder why? Is it to get his own head into that weird space?
