Are Aliens Sending Encrypted Messages?

In this video, Neil deGrasse Tyson discusses the mysteries of our universe and secret alien communications with 'geek-in-chief', Dr. Charles Liu.
What's really causing the expansion of the universe? Dr. Liu suggests alternatives to Dark Matter, including the possibility that our universe is just a bubble in a larger universe.
Why is gravity so weak? Dr. Charles Liu goes into depth about the mysteries of the Gravitron and how to square concepts from general relativity with quantum mechanics. How does time behave while approaching the speed of light? Could the fabric of spacetime be weaved by wormholes?
Should we fear AI? Dr. Charles Liu gets deep as he questions the way humans value themselves in a future dominated by AI. What skills do we need to learn to retain our value in the workforce.
Is there life elsewhere in the universe? Are aliens encrypting their messages to hide from us? Neil and Charles ponder deep questions about potential alien ancestors and extraterrestrial contact.

Nice, except for the music being too loud. It's very distracting.

[@KNIGHTSOFGRAVITY]

I've been developing a theory over the past few years that offers a new perspective on some of the universe's most profound mysteries, including black holes, gravity, dark energy, and dark matter. At its core, my theory introduces the concept of the Gravitonic Sea for our universe and a Multiversal Sea for the broader multiverse. These ideas stem from using field equations to apply a distinct density to both our universe and the multiverse, leveraging quantum entanglement as a foundational principle. My theory suggests that black holes are not just singularities but should be considered "black knots," teeming with gravitons that are deeply entangled with matter. This entanglement extends across the fabric of spacetime, indicating that phenomena such as superposition and time dilation are not universal constants but are localized effects experienced by entities entangled within this spacetime fabric. To illustrate, imagine a speedboat skimming across a lake, each skip across the water's surface akin to the way entities move through spacetime. The faster the boat (or any entity) moves, the less it interacts with the water (or spacetime), illustrating how superposition and time dilation are experienced differently depending on one's velocity and entanglement with the surrounding spacetime fabric. This theory aims to unify our understanding of cosmic phenomena by applying a new framework for considering the universe's density, the intricate dance of entanglement, and the dynamic interactions within the gravitonic and multiversal seas. Through this lens, we gain novel insights into the nature of black holes, the forces that govern our universe, and the mysterious components of dark matter and dark energy. -Okami-KNIGHTS OF GRAVITY-

No.

[@eliaschabinga6576]

Hi, does general relativity imply that gravity only applies to objects in motion? To allow this curvature of spacetime towards a massive object to form a guided path towards which a particle travels and hence appears to be falling towards it? Without the object being in motion, this curved spacetime would imply a static object needs to be pulled onto the curved surface...

[@KNIGHTSOFGRAVITY]

General relativity, indeed, describes gravity not as a force in the traditional Newtonian sense but as the curvature of spacetime caused by mass and energy. This curvature guides the motion of objects, determining how they move through spacetime. However, it's important to note that this doesn't mean gravity only applies to objects in motion. Instead, the concept involves how spacetime itself is shaped by mass and energy, influencing the paths objects take within it. Even what we might consider "static" objects are in motion relative to the spacetime curvature around them. For instance, an object resting on the surface of the Earth is in a curved spacetime and experiences gravity as what keeps it from moving along a straight path in spacetime. This curvature of spacetime affects all objects, regardless of whether they are moving relative to other objects in space; their motion through time is enough to be influenced by the curvature of spacetime. The paths objects take - whether they seem to be moving in space or not - are described by geodesics in general relativity. A geodesic is the closest thing to a straight line in curved spacetime, essentially the path an object follows due to the spacetime curvature without any other forces acting on it. For an object "at rest" on a massive body like a planet, the curvature of spacetime determines how it moves through time and keeps it in place relative to the planet's surface. This is akin to being on a guided path towards the massive object, as you described, but it's essential to understand that this applies to all objects, influencing their motion through spacetime, not just their spatial position.

[@forresthouser5807]

Just wanted to give a tip of the hat to the editors/producers of this video for keeping the incidental music quiet enough to here the dialogue. As a sound engineer, nothing bothers me more than the dialogue being drowned out by the incidental music, and although there's a spot or two where Charles Liu is speaking quietly, for the most part everything that is said can be heard. Good job guys ;>)

[@cspahn3221]

i absolutely adore charles liu- he is SO cool

[@mdre3mnc]

I am so appreciative of Startalk and all of the people who contribute their time to make this podcast what it is. Thank you Neil, and thank you to the whole Startalk team, as well as all of the guests for always discussing topics clearly and enthusiastically. Other peoples love for science can truly be contagious and I would bet that this show succeeds in that.

[@VictarisGX]

Thank you, Neil, for reminding us to keep looking up.

This is why i bought a nice looking ceiling fan!

[@sidsimon5844]

One person recently, goaded into desperation by the litany of unrelieved negation, burst out "Don't you believe in anything?" "Yes", I said. "I believe in evidence. I believe in observation, measurement, and reasoning, confirmed by independent observers. I'll believe anything, no matter how wild and ridiculous, if there is evidence for it. The wilder and more ridiculous something is, however, the firmer and more solid the evidence will have to be." • Isaac Asimov

[@richardfurness7556]

John Gribbin tells of a similar experience in his book 'In Search Of Schroedinger's Cat'. He was a guest on a radio show attempting to explain that far from having all the answers science teaches us how to look for them more effectively. 'I don't believe anything' he said, but before he could expand on this the show came to an end. Gribbin laments that he spent the next several days pointing out to friends that his lack of belief didn't prevent him from making use of such reasonable working hypotheses as the likelihood that the Sun won't disappear one night and never come back.

[@djenkfullplena]

I think the music is distracting people because is too loud. If you low the volume of the music could be perfect. Kiond of white noise. On the other hand, I find the pictures and representation of the concepts in a more dynamic way very useful to guide our thoughts closer to how you see it in your mind when you are explaining it

[@BannorPhil]

Why the need for background music in the first place?

[@jerryross2463]

Didn't even notice it holy christ

[@Doc_Dooom]

But this distracts us from the nonsense they are spewing! 😂😂😂

[@formyloveh]

Geek in chief, never get enough of him.

[@alexeiveselov2667]

I was so intuned with the presentation I didn't even notice the music until I looked at the comments

[@sreneethomas]

Same here

[@Like_Ike]

That moment when your vision comes back in focus after you catch yourself in deep thought from these brain nukes this channel drops.🚀🤯

[@The44kGaming]

Love the Space themed... 👨‍🚀🌌☄️🚀 Background music. ❤ I wish You guys could do like an hour or 2h documentary put together with all the guests you had before, just talking about space.... In a same way this video is done. I'd love to watch that. I just can't get enough of Star Talk... 😅 My favorite podcast and youtube channel. 👏

5:30 - 6:20 smartest thing ive heard in a while!

[@Savagetings]

Dr.Tyson! Im a huge fan/internet student from windsor ontario and i absolutely learn a TON from you! However if i may be so bold as to make one suggestion in regards to your audiobooks! In future audiobooks can you please solely narrate..? I believe the people want to hear your voice not others reading your words.. it just doesnt sink in the same... either way im glad to be able to learn new things with you guys from these videos and books! wishing you the best from canada!

[@armandoramirez7268]

My man said the quantum entanglement between virtual particles popping in and out of existence everywhere is creating the very stitching of the fabric of space-time. I've never needed to hit a blunt harder in my life.

[@casperastronomy]

Brilliant as always, thanks Neil 🖤💜

[@EonThaWolf]

Wooow. I am loving the visuals, the ambiance and the music. It elevates the actual discussion into another realm, inspires thoight, and encourages one to think on a cosmic scale.

[@jay999tv]

[@seantlewis376]

There are stars, galaxies, clusters, and superclusters. But aren't the superclusters also affected by the gravitational influence of other superclusters? What's the next level?

[@mattgraham5992]

Thank you for your message about education. I have been saying that for more than 20 years. I just wanted to shout “wake up!”- retired education technology specialist.

[@aoifedeborha2420]

Would it be possible to have a comparison video for our solar system, then the galaxy, an overview of what they have in common? And the similarities/differences for each? Thank you (:

[@astralmindny9055]

You're joking right? That's WAY too much!

[@astralmindny9055]

How can you even answer that?

[@aoifedeborha2420]

Hey, I’m all ready for the 2hr long version of StarTalk XDXD And I’m not the one with the answers… but mostly I’m looking for things like every observable galaxy has a black hole in the centre, the structures of solar systems, stuff like that (((:

[@CaliforniaBushman]

I hope Brian Greene is right. Matter/Antimatter pairs of virtual particles created everywhere are connected by quantum entangled wormholes that themselves are the plank sized stitches that weave spacetime together. Conveniently providing us with networked wormholes we could use to instantaneously communicate/travel across the universe.

[@philippemasse6470]

Can we, in the future, talk to one another instantly across many light years using quantum entanglement? Is that why we aren't "hearing" space aliens? We have the wrong phone?

Why startalk plus? How is different than Startalk. If it like the best of Startalk?

[@samrodm98]

Beautiful

[@QuantumBlissH]

The more complex it gets the more complicated it becomes to find a “unified”theory. Funny how unified can be a few theories that work together as they build on one another. Wouldn’t be crazy to find out that the final unified answer is much simpler than expected and not as gloomy as one may think (we are in a computer on some “alien” kids thats working on a school creative project? 😂 Or is simply the more we are able to discover the more challenge lies ahead in alignment with what universe’s expansion means? Would that be the definition of self-simulation? We are all tendrils that build towards a massive creation?

[@Russia-bullies]

Nonsense.As some indulge in virtual reality & some commit suicide,we ain’t in a simulation.We ain’t tendrils.

[@setelliott9683]

The energy of "Hello" 😂

[@Sammasambuddha]

The balance of energy in a smile.

[@prestonbacchus4204]

Try this hypothesis: The universe itself is "alive". Thus, all life within the universe is derivative to that life and related to each other. Like all other living things, though we can not prove it, our living universe has a "mind". If it does, we share a mind with all other living things and it's possible we can and do communicate without even knowing it...

[@moonshoes11]

The use of quotations sort of defeats your hypothesis, doesn’t it? And if you claim our universe has a mind, but we can’t prove it….you’ve created an unfalsifiable proposition. It would be irrational to accept an unfalsifiable proposition.

[@Nemoticon]

So how to YOU define the term Life?

[@prestonbacchus4204]

When you consider that all life we know of descends from LUCA, 4+ billion years ago, a kind of bacteria like organism, who's origin seems to be of the earth, but we find no beginning, No telling what form it could take on a subatomic level. Think about it, can a physicist tell you are alive? They usually say no. Do you think they could tell if the universe was alive? Not likely.^ But consider, you are alive, right, so how could the universe not be alive? Are we not universe? @@Nemoticon

[@prestonbacchus4204]

Let's start with you, are you alive? Yes, right? You are universe, are you not (what else could you be)? Then how could anyone argue the universe is not alive? We suspect, statistically, that there is a high probability that life is sprinkled throughout the universe. The living universe could be like a pomegranate, with the individual seeds descending from a mother plant. Or, LOL, any biological model you want to try. How did the universe come into existence? Simple, it was born from the interaction of other pre-existing universes like our own, with a "night sky" of other related living universes stretching out endlessly. A model not unlike the way galaxies are born, including our own "living" Milky Way. There is not really a point of reference yet for determining if the universe is "alive". At least as far as this living model goes, it would, however, predict the existence of other large bodies of mass existing in relation to our own, primarily what would be left over from the big bang event that formed our own living universe. In general, life is known to be a mysterious concept and has been since men started thinking about it. It's not well defined scientifically.@@Nemoticon

[@prestonbacchus4204]

Oh, gosh, I can think of several reasons for using quotes and none of them defeat my hypothesis.^ It's well known that scientists have not proven the existence of "mind", at least not scientifically, not objectively. But you still believe you have a mind, right? So if we can not prove the existence of something called "the human mind" (the word is ambiguous with huge dispute over what it actually means), that is, if that can not be proven, then, naturally, we would not be able to prove the universe has a mind. Do you follow?@@moonshoes11

[@bored9260]

🤷‍♂️ I made a new form of reaction, I call it endothermic conduction… black holes are relatively lodged in space so you won’t see an atmosphere which project lightning… which is a way to avoid saying that the electron charge of negative is producing an electrical charge energy of negative charge electricity… 🤷‍♂️ I lack the concept of how negative charge electricity compliments electro magnetism and gravity. I could link a thought from string theory that suggested black holes had both electro magnetism and gravity and I couldn’t argue about it being a compliment from the other.

[@RDEnduro]

This is great, the music is too much for me, as subtle as it is

[@teppens71]

I'd say just turn the audio on it down a tad

[@shattaknight2217]

Stop the music

[@bored9260]

6:21 I’m an idiot on this one… because I just learn quantum dynamics is relative to different function which is represented by a greek alphabet… so from worm holes I would say relative functions in association to it’s matter which equal a point in dynamics. which is exactly what is, in quantum physics. it has to be relative in the same function and wave path association… 🤷‍♂️ without that concept mankind would be all over the place in their task to resolve a problem that isn’t so visible by our principles and laws of the fundamental physics we all know…

[@bored9260]

i learn that point from last year from angular momentum to super positioning… and now I’m pull Gs in this year…

[@bored9260]

that’s right 2 different points on the same chart.

[@bored9260]

i don’t know if anti-matter and matter are associated by electrons, i you would have to break into an old particles accelerator that predates the hadron super collider…

[@bored9260]

and there is a reason for it… you would have to be allowed to create a new wave function… because there is no association in the dynamics of space as I can show you from a computer situation stand point. remember there is no such thing as a free electron… so it would be a different out of phase frequency which exist on the internet if you look it up but it maintains no relative principle to physics outside a disassociation of different colors overlapping on a histogram, which is a poop shot of justifying it to be a real signal from my end.

[@bored9260]

you know RGB was define by quantum dynamics in stating that color does share an equal dominance in the spectrum of light… 🤷‍♂️ so obviously it’s going to redirect peoples brains to this day to over look an out of phase frequency as a justification of being a color between the red blue and green.

When he captured more than 900 Hessians at Trenton in 1776, Washington ordered that they not be harmed or even plundered by his troops.
