Relativity Round-Up With Janna Levin

[@StarTalk]

Do you know the difference between a bridge and a tunnel?

[@briwood6328]

Yes

[@shkambjaka7570]

Both are alternative roads we created, in one we go over on the other we go under.

[@notsofrankyt]

​@@shkambjaka7570good answer

[@briwood6328]

Over and through, you go under a bridge you go through a tunnel ✌️

[@cgtactical6619]

My inclination is to say yes but Neil has a habit of shattering reality so

[@simba6698]

Dr. Jenna Levin is my favourite StarTalk guest. There's a certain aura she has❤️❤️❤️

[@71borto]

She’s hot ! That’s why 😁

[@childish_hambin0287]

It's probably the boots. 😶

[@ilaphroaig]

JANNAAAAAAAAAAAAAA. She should visit more often on this chanel. Missed her here.

[@MikeJamesMedia]

Any discussion that includes Janna Levin has my full attention. Always hugely interesting to hear what she has to say. Thank you!

So beautiful

[@simateix6262]

Janna is always just a joy to listen to so great to see her again!! I love Star Talk and everyone involved in it. Chuck, Paul, etc.. Thank you Neil and thanks to all the guests who bring science closer to us

[@Baremutation]

You keep posting videos with Janna and I'll keep watching them. Her enthusiasm for this stuff is infectious.

[@ambrosemalone1891]

Janna is brillant. Intelligent and informative. Fair play to her!

[@paytonpryor]

You have been my favorite scientist for years. You helped me learn how to think for myself and not be a sheep.

[@MzeeMoja1]

3:06 “I love being the guest, I love that you’re the host” so genuine and sweet from Janna. Well, I hope I speak for most when I say we love you being the guest and we also love Neil being the host Janna.

[@kcassidy90]

Just discovered this channel! So much to catch up on! Neil is my hero!

[@Kelticfury]

33:18 this blew my mind. Even if we are standing still, we are not standing still in space, we are just standing still locally. The earth and everything else is still hurtling along. So we cannot stand still in space any more than we can in time. In order to be perfectly still (static) time has to stop.

[@leeFbeatz]

2nd time watching coming from Spotify, unbelievable show and wow does Janna have cold style 🙏🥰♥️🌷🌷🌷

[@timoooo7320]

Dr. Janna Levin is so 🔥🔥🔥🔥

[@AfrikanGod1]

Defenetely the best way of absorbing knowledge, with humour, very easy ,fluid listening...

[@Joshua-o5h5k]

Janna is glowing

[@Poke-Cult]

Janna is the sexiest scientist man she looks amazing for her age. Also one of the smartest and informative. Amazing work ! Neil thank you for making learning so easy and grasping at least my interest for our universe.

[@Sajin688]

Right who wouldn't want their mind blown while being blown 😅. She would bring a whole new experience to getting down in the sheets

[@jakobmorningstar]

Remember kids, proper punctuation is important. A simple apostrophe in this comments first sentence changes Jana from “the sexiest scientist man” in to just “the sexiest scientist, man…”.

[@TanyaMasGirl5568]

Love StarTalk! Never stop thinking and teaching Neil and others.

[@mqureshi79]

In the age of idiocracy it’s so refreshing to hear this type of conversation

[@kcbill54]

Jana is very good at explaining complex topics while making them understandable.

[@digibluez]

these talks are truly fantastic and easy to follow

[@user-tc1fw5ms5s]

Janna episodes are always the best!

Janna going to the club after this talk 😂

[@loyertamara]

Uh, hmmm, errr, fidget, Query? We are in the club 🥸

[@Sajin688]

If by club, you mean my place afterwards 😂

[@savagepro9060]

0:35 Dang! I was expecting Chuck Nice! Who else is shocked?

[@KevinCurryRacing]

I love everything about this

[@stevejobs6396]

Neil definitely hit that. No cap.

[@Sajin688]

Who wouldn't want to hook up with such a beautiful and intelligent woman.

[@Sajin688]

She loves how he says, Black hole blues quite a bit it gives her the chills she has commented on it quite a few times. She seems like a freak in the sheets. Plus her intelligence alone makes her super hot.

[@rich.and.rare.100]

I love Janna

[@georgefeener8682]

Love the red boots more intelligence on that stage then in all of Washington d c . Neil and Jana are the greatest ambassadors of educating the masses about cosmos thank you and Paul is awesome as well

[@Marween]

Thanks for the free show.

[@d.tylerbradbury1161]

Two things I was thinking about from this discussion: 1. Telephones only transmit frequencies that are used for conversation, so what Chuck Berry would have heard of Marty's "Johnny B. Good" would have been messed up, 2. The problem I see with the Star Trek Transporter is that you may be able to send a person someday through one, but their memories and experiences would no longer be stored in their synapses, as the order of the firing is how memory works and they are not molecules that can be sent.

[@theduder2617]

Telephones to be factual, were at one time capable of transmitting almost any electrical signal, most of which are useless for communication until the signals are converted into spoken or printed words. They go far beyond simple conversation. Faxes used to be a thing which were sent from one phone to another. Their signals were to human ears, a jumble of high frequency sounds that told the listener absolutely nothing about their contents. The internet at its infancy, was transmitted through telephone lines as electrical signals which to any listener, gave no hint at to their contents. Our use of telephones and their potential possibilities are two different things. And not for nothing, but anyone can call another person and play a song which the other person will be able to hear and make logical sense of. And that would have worked the same back in 1955. Shoot, there was a time that it was very popular to record your voicemail introduction message with music playing in the background. That fun began back when pagers were a hot commodity. I'll give you anything related to star trek, for I am not a fan of any version of that show. But when it comes to the telephone, they have uses which extend beyond conversation, and Chuck would have heard the song being played well enough to understand it was a "sound he has been looking for". Even with 1955 tech.

[@jorymil]

Star Trek is great for throwing sciencey-sounding words out there, like "Duranium" and "Dilithium," or for saying some inane things--they had a nebula that was made out of some heavy metal instead of hydrogen and helium--but it can be mind-opening to think "Is this really possible?" or "Hey--let's try this!" based on some Star Trek thing. Rather than actual science, it expresses sort of a hope for science, which is really heartening.

[@gregczarlinski2811]

Thank god, after so long time... JANNA LEVIN! 🙏🙏

[@damianrodriguez1701]

Nothing against Paul but I was a little sad when you didn't say Chuck Nice

[@mrbunghole]

I was a little bit surprised how involved Paul was with the conversation rather than just being the comic relief. 👏 and that’s not just in reference to Chuck. When they bring on half a panel of comedians and the other half science literate guests, it seems like they have little to add to the actual conversation.

[@answeris4217]

Time travel seems like a hard thing to calculate. How do you know your own coordinates in a world that constantly is moving.

[@tntsoccer21]

It goes beyond that. How do you know the coordinates of the space in a universe that is constantly expanding, stretching, (and contracting?). Your calculations for space in this case have to transcend the earth because space itself (and the coordinates of it) also transcend earth.

[@FlushGorgon]

@@tntsoccer21 Expansion is not an issue, as it doesn't change your coordinates in the expanding fabric.

[@DagmawiWendwessen]

​@@tntsoccer21but, does the expansion is increasing at a uniform rate?

[@tntsoccer21]

@@DagmawiWendwessen I would assume that ALL space is expanding. Stretching out. I'm no astrophysicist though

[@SiqueScarface]

I like Janna Levin's quote "It's actually very, very hard to stabilize an universe."

[@jettmthebluedragon]

No it’s not 😐the universe is stabilized it’s not hard the universe makes it easy it’s when people want to make a universe then yes it’s hard if not impossible 😑their are things that nature can do we will never understand and their are things man made things can do that nature can’t their is never a perfect thing 😑

[@SiqueScarface]

@@jettmthebluedragon I know. There was a nice squib published 20 years ago titled "Gott rendert nicht" (God does not render), albeit this was in German. Nevertheless, I like it very much.

Wow. Am French and I didn't know pourcent was actually written pour cent... Almost everyone use one word.. Well done Janna

[@motogeee510]

The main reason I doubt the future is completely predetermined is because there or 2 many living things set in motion everyday to make the future predetermined. Especially since one enter action of 2 species or like species can go so wrong or so right. Yet we can kind of predict an predetermin the out come of many things based on many other situations an observed reaction.

Neil, there was a total eclipse in the high right night sky. I looked at it once, "Oh my God", I thought. However came on inside. No double take. It was at the crescent. So beautiful and sacred. Clearing zone inhibiting death from the world.

About people thinking that we are the center of the Universe; Looking out into the vastness of space and I can see the same distance in every direction why should I not think I was in the center?

[@jaydavis9812]

I stand amazed at the genius of Einstein, Keper and others to conceptualize spacetime and an ever expanding universe!!! 🤯🤯🤯 thanks Neil for keeping us curious!

[@jettmthebluedragon]

Well I hate to tell you the REAL truth but the universe does NOT EXPAND 😐space alone does NOT expand it’s the objects IN SPACE that move 😐that’s the irony Edward Hubble failed to realize😑and just because something has red shifted that does NOT automatically mean distance 😐take our own star for example 😐

[@jroar123]

If the Universe came into existence from a singularity, where did the singularity come from? Where did it get it's energy to go bang? What is it expanding into if there is nothing outside the Big Bang? If there was no time, how could the Big Bang happen if there was no time for it to move forward?

[@CleverName_]

Very insightful! I’m glad I watched this video.. Onto the next! Their shared knowledge is amazing and so accurate.

[@KrishMazumdar]

This has been such an amazing podcast coz the questions were the best ! Coming from an Indian cultural background I wanna comment and share that the universe is both finite and infinite in the sense that the nature of reality is finite n static while its characteristics are infinite n dynamic.. This is where integration of pure/cosmic conciousness (this is a a vague term and doesnt relate to panpsychism or neuron firings in brain leading to subjectivity) becoming fundamentality makes sense and since conciousness being non-computational in nature cannot be pinned down mathematically n maybe forever gonna stay elusive in the matrix of science and logic.. N yea well umm.. I guess this cosmic/pure consciousness does have an inflated ego and hence under no obligation to make any sense and reveal its elusive nature to us mere humans 😜

[@Mr12Relic]

26:40 This was used unexplainedly in the Doctor Who episode Blink. It involved a transcript of a recorded conversation that contained specific necessary information 50 years apart. The partial transcript was filled in following the conversation, then handed off presently to The Doctor before he would be sent back in time to require it.

[@md.noorulkarim5542]

Entertaining and educating. Thanks to the Stars.

[@tekknojunkie]

In reference to The Big Bang theory; due to the relative nature of spacetime, as you near the infinitely small point at the start of the Bang, time becomes infinite AND also ceases to exist, therefore the Universe both does AND does not have a beginning/end.

[@marksmorphs]

Speaking of time travel. If I was able to go back in time 10 years; there would be a 10 year younger version of me around. So where would the extra matter come from in order to create the "me" that is now back in time? I didn't think you could create new matter like that.

[@Onestringpuppet]

But in the assumption here, you wouldn't be 'creating' extra matter. You'd be adding it to the existing matter by bringing yourself to that time

[@dianthaweilepp5294]

Same difference. More matter in the universe.

[@justinerogers8696]

Dear Neil, everything we do, every decision, directs us on our own Spiritual journey.. every decision we make which is our own free will, creates our own existence around us, each of which is an alternate dimension. Our Spirits cross paths with other Spirits all the time and we are all on a journey back to our Creator. Our Spirits endure until Judgement Day. We live many lives on our journey to God.

[@komakozie]

Janna is Very Attractive

[@macanoodough]

Deja Vu is when the hippocampus, an area of the brain mainly for short term memory, takes over as a processing center. It also masters things you do in repetition, and is what allows a batter to hit a fastball. Since it's hardly employed for processing, it's use at all invokes some conscious idea of memory, the feature that's employed 90+% of the time it is in use.

[@dianthaweilepp5294]

Since the universe is expanding, it is getting bigger. It doesn't matter if we are in the middle or off to one side. A) what is the edge like? B) what is the universe expanding into? C) is it expanding evenly?

[@scottward1611]

Neal is great

[@Incorruptus1]

Einstein's issue with the universe being finite, was love, love for life, life to be able to exist infinitive. He was struggling to see it all go one day, even though he was not meant to witness this ending, in fact, none of us living now, will. It would be more comfortable to him, it being infinite, than finite. Which to me sounds like pure and utter logical, professor.

[@spiritculture4401]

Thank you. I enjoyed this. This brings to mind a percussionist thought. If light could be treated as a solid between two points--say, two light seconds and you could strike that light at one of its acoustically sensitive points, it should instantly vibrate the beam of light at all points, creating a peace of spacetime where a universal now exists. That's my two cents. Our clue is that electricity already operates in the realm of the speed of light. We use time delays at big concert venues between speakers so audience only hears the music once.

Basically traveling back in time is against the present laws of physics. Maybe in a separate universe with different laws

[@ediscool]

If there’s another universe…

[@erock7138]

@StarTalk Can time travel even exist in a universe with free will? I feel like time traveling in general would be purely an observational type of thing. Like your consciousness traveling to a point in time. And observing the events as they happen in real time if your consciousness traveled to the past. And traveling to the future, would consist of a multitude of possible future realities depending on the choices we make. Basically something like a Christmas carol…

[@jettmthebluedragon]

Time travel does NOT exist 😑even if you change the future you can’t just thanos snap someone just like that 😑as it does not matter if we will never live again who cares ?😑and if we will live again do you think your the only people who thought of time travel only to fail 😑? People will fail again again and again 😑because time travel does NOT exist 😑as for the universe having free will that’s fake the universe does NOT have free will 😑that only applies to organic chemistry like you me animals and plants 😐we have free will but that free will is EXTREMELY limited 😑
