What do you think your life is like on other worlds? You can learn more about the many worlds theory in Sean Carroll's new book 'Something Deeply Hidden': amzn.to/37sFhgo

Sean Carroll is one of my favorite theoretical physicist I could listen to him all day, thanks for having him on as a guest. Great episode John I thoroughly enjoyed it.

Mowed lawn, poured beer and now sitting outside while nerding out. What could be better!

It's comforting to know that somewhere in the many worlds there is a me who is happy.

I had a dream last night that I was the host of Event Horizon. For a moment there, it all seemed so real. Ah well, I guess it was just a glitch in the multiverse.

Just want to thank you for all your high-quality work and the long documentaries

Perfect timing, I'm going to grab the popcorn👌

This was the best discussion I’ve heard on the subject. Perfect follow up questions enabled Sean Carroll to make it surprisingly understandable 😊👍🏼

I look forward to these, they make my Thursday nights feel complete! Awesome interview guys 👍

Sean Carroll? What a treat! Was listening to the other popular podcast at the moment with Nick Bostrom... my brain is going to appreciate that I'm switching to this one!

I'm a huge fan of Sean! His book "The Big Picture" truly is an awesome read. Hearing him discuss biophysics eventually led me to make it my major

Great job John - great to see Sean on the show! Excited to see what's coming in the future!

Sean is such a delight to listen to. Great show as always!

Loved this one. You're a perfect host, hopefully you'll get more of the popular physicist greats!!

Oohhh that Outro! Great work putting many worlds into dramatic action :)

Holy crap, Sean Carroll. It's great to see how this channel is growing JMG. Good job!

Sean Carroll is my favorite physicist!!! How did it take me two days to see this video!? My metric for trusting physicist is by how often they say 'I don't know' and Sean does this more than most. Beyond that he doesn't get hung up on the great debate of whose interpretation of QM is most likely to bare fruit. Being a theoretician he can move head on with the most likely understanding, even though he's in the minority. I love this channel and all it's great conversations. Thank you for sharing!

Wow this is an absolute treat! The quality of the guests on this show just keep on impressing. Also, the description says: John Michael GodLIER... John is certainly a Godly KZfaqr!

Always a great pleasure to hear Sean Carroll. He's just amazingly good at putting these difficult matters in clear words.

Reminder: Always watch to the very end of Johns videos! Great stuff!

WOW! You actually got Dr. Carroll on the show! I'm so ready for this!! Love his podcasts and your show. This is really a spectacular crossover!! Thank you both!

Thanks for the excellent interview! More than my mind can boggle to be sure, but fantastically interesting!

I like to pour myself a fine single malt scotch, and puff a nice cigar, while a listen to this stuff and pretend to know what TF they are talking about.

One of the best videos I have seen on the internet in years. Thank You for sharing this John.

You really set a high Benchmark with this episode.. my favorite so far.

That plug transition was amazing. Well done John.

Excellent content as always JMG, keep up the good work 👍

Since subscrib1ng to this channel my quantum physics is 1000% legitimate.

What a treat! Sean is a delight and fostered an epiphany for me today.

Hopefully there’s a world where I have enough time to watch this.

Another outstanding episode! Great work!

Such a humble and smart interview by JMG, excellent work, love Sean, his book The Big Picture is one of the best out there on physics.

Awesome man I did not even know about this channel. Very professional.

Great episode John! Lots of fun stuff to think about.

The wrap up at the end was awesome! 🤣

By avoiding the Quantum Suicide issue, Sean is avoiding the big reveal! We're all playing it just by living our lives. As we get older, only versions that didn't die will still be around. When you're 300 years old, you'll pretty much know the truth of the multiverse just by reason that your life story is so weird by that point.

Iam from Germany and it’s sometimes so extremely hard to discuss certain topics in English because there are no words. But that makes it easy to understand a lot, mostly in science.

Thank you for this video. Absolutely fascinating!

Great show, as usual. Oh, someone misspelled your name in the description. Its kinda funny.

I love this program. Thank you guys!

Hahaha, Anna just all like, "Wait, wut?" got me laughing stupidly hard.

Great interview. Many thanks!

amazing episode!

Always asking the great questions. Thanks John.

Never heard this one before but loved the ending. You have the best guests and show ever.

Excellent discussion! The questions were nicely fine tuned to elicite intense in-depth responses from the always thought provoking Professor S C. If I might add from the other world for which I reside, I've been fond of saying that light is matter in motion and gravity the magnetic moment of the latter. If correct, then, it follows that the other worlds should be expected to have variable force's or layers of light in order to support evolutionary copies of particle charge from very different gravitational fields. Nice production. Outstanding! The graphics gave feeling and meaning too the fluid nature of the universe. Can't wait for more.

Well done event horizon another. Outstanding vid

Fantastic interview

Sean Caroll- the way you explained quantum mechanics... its brilliant

Thanx for sharing this great new Episode of 'Event Horizon'. This time you managed to get Sean Carrol discussing one of the most intriguing aspect of Quantum physics. Love Your work mates :D Now I watched and read many stuff from Sean Carrol and each and every time, he boggles my mind. And every time when it comes to the Kopenhagen interpretation of QT my Guts tell me: "there's something wrong with it, better eat a pizza and drink a wine". And here are my 2 cents: the Kopenhagen interpretation of QT states, that each time an Experimentator makes an quantum experiment, of the sort of figuring out the quantum state of an quantum object, both possible results become in to being or to realization. In an Universe without Experimentators such 'splitting' won't happen. Leave alone this implications whether or not there are 10 or 10 trillions of Experimentators defines the number of different, parallel existing, worlds, right now (and we know, there is no such thing as 'right now'). But I do not have a 'Space' problem here because I think the Universe is veeeerrrrrrrrrrry Huge ;-) Multi dimensions and 'what have you' gives the space needed. But what about the energy and entropy of this experimental new created realms? How can entire universes be created instantaneous by making a Doubble-Slit experiment (or other well performed experiments in the last 20-30 Years). Not to mention that each one of this, is created infinite fast and it doubles Mass and Energy. And does this 'spooky' parallelision of the Universe not contradict to the fact of nonlinear fractal evolvement of spontaneous evolving particles and antiparticles (Hawking Radiation) since QM is not able yet to predict the interactions of three single particles. It would imply that each quantum object in the Universum nows each quantum sate of any other quantum object- "instantaneous". The simulation theory would not need such duplications if I understood correctly what I read so far. Feel free to correct me and help me to understand what's the point i am missing here. (and please excuse my humble English regarding this very complex issue)

I absolutely love John. He always has other smart people on his shows and has a pretty good since of humor too.

Whaaaat? You got Sean Carroll on? Pure awesomeness.

Sean M. Carroll is one of THE most prominent people on Earth, more influential than any celebrity - well, he should be!!

“There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.” HGTTG

Haha perfect ending

This channel is awesome, I love it

Hi John.. great show as always.. Can you consider getting an expert on Abiogensis research to hear about the latest developments in the field?? and implications to FERMI paradox. will science ever be able to synthesize a single cell organism?

How do we know that we can't interact with the different worlds? Is it shown in equation?

Big thanks for this interview and video Godier. Everyone needs to hit the notification Bell on you my friend

Okay, halfway through and this is already the trippiest video i've ever watched xD

could the other version of me tuning into this show please tell me were I put my/our reading glasses.

oh its thursday again... nice!

The fact that when you look at particles they change makes me think of the way games are programmed it only shows as much as your screen is looking at, perhaps were in one

Excellent Theory Documentary!

Absolutely love your channel ❤ please 🙏 keep up the good work 😊🏴󠁧󠁢󠁷󠁬󠁳󠁿👊✌

Bought the book straight away.

Hi John which language in the world today is best at describing quantum mechanics?

I love the closer... you make science fun. I love your channel

Fantastic episode I really enjoyed the interview. This reminds me of one of my favorite Star Trek episodes Mirror Mirror. Just like my avatar you had evil spock with the goatee. Of course considering I myself have a beard I wonder if I'm evil me? 😈 Thanks for the episode!

This topic and the possibility of nothing existing before our universe, or whatever came before that, is the most frustrating thing to me! It is fun and exciting, but also scary because I desperately want to know the answers before I die.

Within the infinite possibilities of superposition, there is a reality where 2 million people are Naruto storming Area 51 right now.

Is double slit done in a vacuum chamber? Otherwise, all the electrons are observed by the air.

Thank you Mr Goudier. The current scientific outlooks are incredibly snooty and close minded. The graphic depiction of the particles amassing to create the wave effect is brilliant for visual learners. Indeed, the montages are all highly appropriate.

I just LOVE these ideas

Finally a srsly good scientist interviewed on this channel.

Great show, great guest!

Jorge Luis Borges's short story, "The Garden of Forking Paths," gives its own take on the many-worlds hypothesis and was written at least a decade before Everett proposed his idea.

It's very satisfying that you pronouce your last name correctly...oh and great videos, thank you for teaching me so much

oOoOOo spooky ending!

I think the work around for imagining how the illusion of choice causes a new universe.. like me choosing to write the number... 19 instead of 2 caused a new universe to spawn.. I believe the solution is to assume that I was always going to write 19 instead of 2. The big bang, whatever it is or whatever caused it created a universe where I was always going to write those numbers. All the external stimuli and life experience was always going to influence me to write this this way on this video that Godier was always going to make and Carroll was always going to be a guest on. Everything that has ever happened or will ever happen is determined from the very beginning. This could possibly explain delayed choice quantum eraser as well. Instead of imagining the electrons or whatever going back in time and changing its past based on if we choose to look at or destroy the information that tells us what slit it went through... I think it instead can "see" the future. It is already determined which option we choose. This eliminates extra work for the electron and makes it more simple. What process or energy powers an electron going back in time? Its simpler the other way. And the only way we have different versions of ourselves where I write 18 instead of 3 is it's just another big bang in an infinite number of them. Its inevitable even if it takes a trillion trillion trillion years.

I view the entire thing as a field of flowers. Each cosmological universe is a flower with many petals, which are the different realities and timelines in its physical space.

Sean Carroll’s ability to explain difficult concepts is unparalleled. Except perhaps in parallel realities.

cool ... _luv the visuals too !_ :]

You've probably been asked this dozens of times, if someone can point me to an answer I'd appreciate it, but do you have this in podcast form? I'm not really into podcasts, but this would be the perfect thing to listen to on the morning commute.

Another great video. Thanks! Can you post something soon about this new interstellar comet that just got spotted..? Always look forward to your uploads. Thanks again!

Every time I think about the value of thinking about the implications of many worlds on my life I think - maybe - that I might be doing the best in the world in which I never thought about the implications of many worlds on my life, but I try not to think about that.

Could there be another reason for wave function effect? It doesn’t make sense that by observation with no physical interaction can cause a change in behavior. Perhaps wave action ALLWAYS occurs but through observation we cannot see it.

At the beggining I was like, are there guys experts, then i listened the músic on the background, alright, this is legit.

If there are an infinite amount of parallel universes out there, and there are infinite versions of you each taking alternate paths in life, that means that there is a version of you somewhere that murdered his(or her) entire family. Think about that.

I wonder if the change brought about through observation has something to do with the fact that everything is radioactive, whether its a machine made by a person, or the person themselves? Do photons and other radioactive particles emanating from the machine / person interact with the particle being observed and thus change its behaviour? Is it possible to create a machine that's completely free of any radiation, including the form we take for granted, heat?

Given that mediators of forces are particle-like, you can actually compress those many universes. For example, whether one atom is off by a iota, is below the threshold affecting the moon's orbit and so forth. Effectively you get the independent domains (bounded domains) the microscopic the differences remain.

Here's what I don't understand about the double-slit experiment. Can't you figure out which slit the electron went through, based on its arrival time? Because the path lengths aren't the same, except right in the middle of the screen. If it was detected on the left side of the screen, then there was a shorter path length if it had traveled through the left slit, and a longer path length if it had traveled through the right slit, so you should be able to figure out which one it went through, based on the exact time it arrived, if it was propelled at a consistent velocity in the first place. And we're not talking about a tiny, tiny difference in distance that is drowned out by quantum uncertainty of its exact position and momentum, we're talking about a MACROSCOPIC difference in distance in the path length between the slit on the left and the right. So why would a "detector" on the slits to detect it there, make a difference, and destroy the interference pattern? The interference pattern should already NOT be there, just because it should be in principle possible to discern which slit the electron went through based on its arrival time.

i don't completely understand the inner discussions of quantum theory or string theory itself, but i have such a creative, open, and vast imagination. So i could kinda understand what yall were talking about. But i feel as we continue through time, even more complex theories will arise. Who knows maybe we can get solid proof one day that the multiverse theory can be properly proven. There is so much that we can't understand or fathom. But hey we are the groundbreaking generation that is starting a long - term trek of universal knowledge.

Name of music at the end?

Where is all the matter coming from, does it instantly double when you make a choice between two roads? Or, does it split into halves that are half the size and mass it was before you made your choice?

New book? I see Audible has it😀 I did enjoy his book, "The Big Picture."

that ending was cute... ;] wait, what? even machine stucked... there is something silly in this. beautiful, just beautiful. LIKE WHOLE TALK. My ears was glued to your voices for the whole time.

Perhaps it can be understood in this language that the wavefunction is a perpetual expansion of potentiality. As time moves forward the wavefunction evolves ever greater complexity as it undergoes mutation which expresses all potential realizations of form. Just giving it a shot

Good episode

I didn't think there could be things that would blow Anna's mind. 😂
