A Ripple in Spacetime with Neil deGrasse Tyson & Charles Liu

[@StarTalk]

What other questions do you have for our Geek-in-Chief?

[@ADHDMedia]

What are your thoughts on the harvesting of permafrost for bar and cocktail ice

[@Goodjobeveryone]

Thoughts on the possibility of white holes and might they have an event horizon that is expressed across the universe as an opposite of the what we know of black hole’s? Apologies for any ignorance displayed in my question and thank you for any input.

[@Goodjobeveryone]

@@voodoophilFantastic question!

[@dwoopie]

Speed of light is RELATIVE... speed of time is constant...Galileo would already been at proxima centauri b... with warp drives... no density in a vacuum ...so what speed should stop us?... it does not even make sense...

[@michaelccopelandsr7120]

Will you please help me to change the stars? What I mean is, help get the IAU to, OFFICIALLY, make a new constellation out of Orion and Pleiades (Subaru). I figure it's time to put something up there that's relevant to us, don't you think? Take Orion's belt and Betelgeuse becomes the head with a baseball hat. The 3 stars of Orion's belt make up the 3 fat belt loops on a baseball uniform. Below the belt are two legs bending at the knee. Saiph is the back foot and Rigel is the front foot. The feet aligning perfectly under the bent knees. The spear pointing at "Subaru" is the bat being swung and "Pleiades" is the baseball flying away after being hit. Bellatrix is the hand that let go of the bat. Put it all together and you get, "THE ALL-STAR." In my case, I see a left-handed batter and I imagine a "7" on the jersey. Which makes him, "Mickey." (As it should be ;-) But you can put any number you want, making, "THE ALL-STAR," any player you want. It'd be wrong of me to not, at least, try. This is me, trying. Pass it on, please and thank you. Don't worry, where I come from, crazy is a compliment. ;-P

[@RobertsCandR]

I must have watched at least 100 episodes of StarTalk. My biggest takeaway from all the shows is this. It's the fact that the questions being asked to people like Neil, Chuck, Gary, and Charles, just prove that there really are a lot of intelligent, inquisitive, and curious people in the world. For me, as an older person, gives me such positive hopeful feelings for the success of humanity. Keep in mind, this comment is coming from a man, who when he was in his mid 20's, the internet was just barely an idea, and a cell phone looked like a walkie-talkie. My point is, as old as I am, I'm still impressed with the consistency of one of the most important human characteristics. And, that would be the need to know and learn. Truth be said, that's something we're really good at. Now, if we could just get over our worst human characteristic, "Greed", there's no telling how much good we could do for humanity.

[@Liapjr]

Thank you!

[@nightmike7655]

As a late-twenties, I wish this keeps up when I'm old. I am a little worried when looking at the world right now, but I don't know if that feeling of seeing ignorance and intolerance towards science is present in every generation.

[@PdroxCbon]

Thanks sir, that was inspiring to read.

[@uncharted7againblackking256]

My friend what if I told you the planets around you used to exist and we really in reality living in dark times and religion is also apart of well still in dark times but it's nothing wrong with reading if you catch the hint

[@dbrew02]

This is exactly it. We can't move forward until we get passed humanities GREED. I heard someone say I forget who but there's a problem with humanity when u have starving children and billionaires living in the same place on the planet.

[@01ai01]

Dr. Liu is a great guest. I think he explains things realy well and has a good sense of humor.

[@nickhodgkins7318]

Charles is so dignified, moderate and well mannered. He is fittingly complimentary to the humour and dynamic discourse of Chuck, Neil and Gary.

[@FrustratedAeroBoys]

this is an underrated comment

Charles Liu is such a force of nature. This team of Neil, Charles, Gary and Chuck is amazing.

One reason I love watching star talk with chuck on. It's because he throws the joke out there at the exact time. It's needed and the exact time that I myself would throw one out like he did with the charlie brown joke.

Man, I love that Chuck is on the show. It kind of makes it more like high school mixed with college. He makes a conversation actually normal and not just about a bunch of experts yelling at a bunch of facts about different topics

[@SanGeet0510]

This thing about photon "slowing down" in matter - when electrons absorb the photon traveling through, its wave function collapses and when the electron emits to get back to its original stable state, it emits a new photon 9whose energy will have to smaller than the absorbed one?) So it isn't actually "re-emitted", but just emitted. So light didn't "slow down", but was absorbed and and a different one was created

[@CiaoBello21]

Charles obviously knows more than most of us but he is humble about it. But in his perspective, he doesn’t know as much as he expects himself to know. This goes to show that everything in our lives is relative. I wish I had a professor or friend like Charles Liu 👍🏾

[@michaelccopelandsr7120]

Time is fascinating. I worked the subway stations for nearly 10 years. From one end of the city to the other. Every so often I would notice the city would be saying that, "Today just flew by" or "The day was just dragging along." How can an ENTIRE CITY, with NO INTERACTION with each other, until they used the subway, complain about the same time paradox unless it was effected by it? Maybe a time distorted bubble the earth passes through in its revolution around the sun. Maybe random waves of time distortion hitting the earth? Maybe they're given off by the sun. Maybe they're from outside our Terran system and reach us in intervals. ???? 🎶Ti-i-i-ime, is on my side. Yes, it is!🎶 If you can think of a better way to do a blind survey - of an entire city - in that small window of opportunity, well then, I'm all in. Until then, I invite you to spend a couple years in the subways. Between 2pm -10pm and you'll see for yourself. Just listen as an entire city gets off of work and gets out of school. You'll see it's more than a, "coincidence of circumstances."

[@tschorsch]

It's more likely that our perception of time is very affected by psychological conditions and there are events and conditions that will affect large numbers of people simultaneously. Emotions are often transferable, so if one person is experiencing a dragging day, and expresses that, those around them start feeling the same thing. Humans do not perceive the passage of time like a clock does, they perceive it by how preoccupied they are with other things. When that is interrupted by something political or the weather and its potential effect on their commute time, the anxiety interrupts other tasks they were performing. It's probably an evolutionary survival mechanism.

[@michaelccopelandsr7120]

Neil and Chuck for 2024!

[@Arrows_Driftwood]

Charles has been my favorite guest. Further to jello, I imagine with the right surface tension on a viscose surface of jello, if an object or skittle was on the surface it could conserve energy while the jello exhibits fluctuations, pushing the skittle across the surface to other locations on the 2D surface of jello. What a fun experiment.

[@saerohmajec7099]

Niel and chuck really need to take a lesson from Gary and learn how to sit and listen to their guests. You guys could get to more questions things could be easier to understand and people can get the whole picture if you'd simply let your guest finish their sentence. Seriously every single guest that comes on you guys interrupt them numerous times. It's very annoying. I love hearing from the guests, but when you guys push your own thoughts or opinions in the middle of what their saying it usually just send things off into a tangent that just wastes time for other questions that could be answered. Please please please, just let them talk then add whatever you think needs to be added to what they said.

[@Megan-he5nl]

I think a lot of that is trying to tow that line between education and entertainment. I don’t disagree with the sentiment, but I think they’re trying their best.

[@basti1615]

[@tschorsch]

AI doesn't necessarily need to have a sense of morality to solve problems like climate change. You wouldn't just ask the questions simply, but put parameters around what success meant, which would include things like not killing people and preserving or improving the standard of living. One of the biggest problems in solving the problem of climate change is people who have vested interests that would be hurt. Their resistance includes manipulation of a large part of the population by spreading vast amounts of disinformation, as well as legal bribery and excessive control over politics.

I can't really say how many episodes I've seen this far and why I'm watching this (or have subscribed to this channel) but that's not part of my interests in any way. I must admit that watching this makes me feel good, relaxed and calm for some reason. Maybe indeed time has more dimensions and in one of them I'm interested in science and universe but in this dimension I've not reached that point yet 😀

[@dalton6173]

Awe that was so cute seeing you finally figure out that the event horizon isn't just a real stagnant thing and instead just a term that we use. Also him realizing that the gravitational field much like the gravitational field of our sun goes much further than we fully understand. Therefore it just has to propagate just outside of the region where not even light can escape for it to have a chance of breaking off. Wishing he got it a while back although better late than never.

@5:30 What if other beings on this planet now perceive time differently? How would a "hive mind" perceive its "time" that it has to accomplish it's goals? Is the lobsters perception of time what gives it it's "immortality"? Do some hives grow larger because if this perception? How does a tree perceive time? Are the rings that it forms proof of a biological clock? When plants die and return every season, is it really something new?

[@dennisestenson7820]

2:30 time is one dimensional for each particle. Every particle has its own unique world line through time and space. And time _is_ 3 dimensional in its gradient - it has a different rate depending on direction (especially wrt a nearby source of mass-energy and direction of motion).
