If gravitational waves are ripples in space-time from massive cosmic events, what other phenomena could we observe through these waves that might deepen our understanding of the universe's structure?
Thank you for sharing this with us. I really enjoy these. RE; terence howard video. I think that this is a classic example of confirmation bias. Insofar as his apparent inability to accept even the slightest disagreement with his stated position regardless of whether that point/critique/information etc is valid or coming from a place of respect and enthusiasm for the topic.
Perhaps we could detect the creation of heavy atoms being formed in the cores of Neutron stars. I suppose that change of the gravitational waves frequency could maybe be sent by the lost mass during the explosion or even the novas if those types of stars have such cycles ( I need to check to make sure if they have nova cycles). Another way could be by observing nearly dying black holes to see how the hawking radiation works in the lifetime. I predict that hawking radiation rate changes throughout the life of black holes but I see this being extremely difficult or even impossible to detect as black holes that are easier have way longer lifespams than the universe's age.
I've BEEN posting a story about working in the subway and noticing a "time paradox." Here... 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 they were all effected by the same outside, "interference." MAYBE a time distorted bubble the earth passes through in its revolution around the sun. MAYBE they're the effects of gravitational waves. Either side of the wave effecting time just enough for we humans to notice. Making time seem to drag on the upside and fly by on the downslope. Or, vice versa. MAYBE they're given off by the sun. MAYBE they're from outside our Solar 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 the small window of opportunity, I'm all in. Until then, I invite you to spend a couple years in the subways during rush hour 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."
Chuck is like the autocorrect feature nobody asked for-yet, once it's gone, you realize not only how much you rely on it but also how essential it has become in your life.
You are simplifying. Technology didn't exist to check his theory and calculations, but the math was there, and it was proven pretty fast, and humanity accepted it in an instance. That is why he was so popular and known. But to prove it in experiment, with lasers, with super sensitive sensors and gears, extremely reflective mirrors, computers... to dig tunnels... that required time, and money. A lot of money.
Wrong. Quantum physics has built upon general relativity and is the accepted theory but was theorized in the 1800s and gained more credibility in the 1930s. Einstein discovered e=mc² in 1905. We understood these concepts almost immediately. Putting them Into practice is a much larger beast. They proved on paper that they could make a bomb splitting an atom, yet it took them years for it to be realized.
Bro Chuck might not always be available to entertain us, he could get sick, be busy, have family issues, go on a vacation... I don't understand why every time he's not on (which is rare), I see these types of comments.
The liquid wax doesn't burn. It only burns as a vapor. The wick carries some of the liquid into the flame where it is hot enough to vaporize, feeding the flame.
@@gungan7859Yes, but the OP is saying the wax burns only as a vapor, not as a liquid. Whether or not that is true, I don't know. Is any liquid even flammable or just the vapor from a liquid?
@@ridetheapex I'm not so sure about that. I haven't seen any demonstrations of Cesium on fire. That is to say, I haven't seen liquid Cesium oxidizing via a chain reaction with a flame. Not saying it can't happen, I just haven't seen it. All the explosive reactions in water seem to actually be hydrogen explosions from disassociated water molecules. Very cool, but not a liquid on fire.
The interplay between photons, fire, and gravitational waves presents a fascinating intersection of physics that illustrates the complexity of the universe. Photons, as the fundamental particles of light, play a crucial role in our understanding of energy transfer and the behavior of electromagnetic radiation. Their interaction with matter, including processes like combustion, showcases how fire emits light and heat, fundamentally changing the environment around us. On a different scale, gravitational waves-ripples in spacetime caused by the acceleration of massive objects-provide a profound insight into the universe’s most energetic events, such as black hole mergers or neutron star collisions. The detection of these waves has opened up a new window into astrophysics, allowing us to explore cosmic phenomena that were previously beyond our reach. Together, these elements highlight the beauty and intricacy of the physical laws governing our universe. The study of how photons interact with matter and how gravitational waves carry information about cosmic events enhances our understanding of both the microscopic and macroscopic realms of physics. As we continue to explore these areas, who knows what new discoveries await that could further illuminate the relationship between light, energy, and the fabric of spacetime?
I am sorry, but a very simple first question was not answered: why does fire release light? Fire releases light due to the process of excited atoms and molecules releasing photons. When a substance combusts (reacts with oxygen), it generates heat, which energizes the atoms in the burning material, exciting their electrons to higher energy states. As these electrons return to their normal, lower-energy states, they release the excess energy as photons, or particles of light.
Yes, thank you. Neil sometimes gets a bit high-minded about things and forgets about the questions that were asked. Also, I think that if the kid who asked this question sees your response then they might have a few other questions such as, "What do you mean about electrons going to higher and lower energy states?" I suspect that probably hasn't been in their curriculum just yet. So be prepared for that should that kid see your post. And frankly I hope they do.
Where does the fire come from? Well, you know sweetie... When Oxygen and Hydrogen love each other too much and add few other elements in a certain group activity... It creates FIRE! 🔥🔥🔥🔥🔥
"So...what did that have to do with birthday candles?" Made me LOL because I'm usually the Neil in my family, always going too deep at times and losing track. Love it.
The candle burning process can be better described as the fire heats up the wick, allowing the wax to melt and evaporate. The fume of wax vapor mixes with air which is rich in oxygen, and it meets the burning criteria (fuel, oxygen and heat). The heat from the flame causes the wax at the tip of the wick to evaporate, the capillary effect within the dried up tip keeps drawing the molten wax up to fill the wick. It won't flood the tip of the wick as there is a fine balance between wicking force created by the flame drying the tip, and gravitational pull which pulls the molten wax down. Try extinguishing a candle flame, you will see a wax fume rises due to lack of heat.
The Nobel people should have a "contribution" additions to the winners of the prize for acknowledging the prior work needed for this current accomplishment...
That would quickly descend into a confusing laundry list of cascading names because all science builds upon previous work of science. And if you wanted to avoid that, where is the cutoff?
The reason it confuses ppl that half the matter of a star is blown away and what's left creates a blackhole is because we tend to think the blackhole is created because there is just so much mass but- in reality you can turn a paper clip into a blackhole- you just have to squish it down into a tiny enough space that it becomes so dense- it creates a tiny little blackhole. The smaller the amount of mass you have, the smaller the space you have to squish it down into to make a black hole- to reach it's Swartchild's radius. The radius is proportional to the mass- the smaller the mass, the smaller the radius- and vice versa.
That might work out as napkin math, but black hole event horizons are from their gravity being high enough to not even let photons escape it. It's not about the size of the space the mass is squished into, but the amount of mass that has accumulated to the point of having powerful enough gravity to squish that matter down.
I love and prefer chuck as much as anyone. Can you imagine even having the resume to sit in for him!? I respect anyone that can even take his seat when he's not in town.
2:34, my parents kept using candles, and not the shaped numbered ones, up until their passing. Dad passed at 57, Mom at 54. They got around having an army of candles, trying to light them with a flamethrower, by having large candles count as 5 or 10 years, then getting to the number with tiny ones. Made arranging them a nice artistic exercise.
17:40, the laser beams "know about each other" because they stem from the same source. The emiter is pointed at a 50% 45° mirror, so half the light progresses forward, half deviates to the side.
Grew up in Hong Kong kids had a tradition of lighting candles in mid autumn festival. One night me and a few cousins were doing that near the lobby of the old apartment and somehow decided to threw all the candles into a metal bucket and light it all up. The fire got so strong the adults came out and had to smother it out. We got an earful. I've always been told that kind of fire is more dangerous than regular fire and now I know why.
This was a beautiful episode to listen to. It's incredible to listen to Neil speak off the cuff about things that are so profound. Compare this to politicians who can only ever read from a script. Really puts to shame.
A photon doesn’t really “know” how to move at the speed of light. A photon moves at the speed of light because it is itself light, and thus the definition of “the speed of light”. Photons will always go the speed of light, because they’re the gauge by which we measure them. Now they can be slowed in a medium, but whatever speed they are going is the speed of light in that medium. It’s kind like saying what is the speed you walk measured in terms of the speed you walk at any given time. It’s always the same.
Corrections: 1. There is no such thing as "mechanical energy". There is only Potential Energy, and Kinetic Energy.. Taking the elevator up in a gravitational field, increases your potential energy.. Falling directly toward another object in a gravitational field increases your kinetic energy relative to that object, and hitting that object simply transfers your kinetic energy into the other object, producing kinetic energy in different directions (some of which is in the form of photons) which has mechanical effects. 2. Melted (liquid) wax does not need to be above the boiling temperature of water. You can drip candle wax onto your skin without being burnt by it. In fact, during candle making it is recommended to keep the temperature below 200F otherwise it can damage the wax's structure and color. If you raised the candle wax temperature up to the flash point (when its vapors burst into flame) then yes it is well above boiling temperature of water, but that's just a mistake, not a fundamental characteristic of melted candle wax. 3. Liquids (including candle wax) do not directly burn. They must first be heated until they vaporize into a gas, and *that* is what burns. A candle wick burning is an end effect, not causal. It is simply a vessel for liquid wax to be carried up to a point that the flame can turn it into a vapor and that is what burns. A wick only burns itself down when the level of the liquid wax drops far enough that it can't be wicked up in time to cool the wick itself (through the vaporization process).
Imagine being lucky enough to know 1/3 of what Neil knows. I have learned a lot from his videos. I always imagined astro physicists would be droll and serious, but Neil is the most upbeat scientist ever!!
@@randallbesch2424 And eventually some heavier elements, and if it goes supernova some even heavier elements yet! What I find amazing is there was enough hydrogen left over from the first generation of stars to light up and provide heat and light to a little ball of rock and water.
It all comes down to the Heisenberg uncertainty principle. If you would want to observe anything beyond planck scale the energy of the photon needed for such observation would create a black hole with the mass of Planck mass and Schwarzschild radius of Planck length.
I liked this guy! Funny commentary but kept his jokes concise. Sometimes I’m like ooooookay chuck…ok let’s go back to Neil now, we get it 😂. Love and appreciate both Chuck and this dude!
I was a little skeptical until he brought Neil back on track lol then when he said "I thought you told the police it was an accident" I cracked up 😂😂😂😂
When I was a kid, I was lucky to participate in a leadership course with the national guard. Part of the course was climbing a 32 ft light pole, and jumping off. The 1SGT said that the pole was 32 ft because if we fell at 33, we’d die. Thanks for the memory. 😅
Couldn't get through this . If harison could turn it down by about 70%, that would be great. Hopefully, I can come back to this another time. Thanks for the video, guys. Super interesting
@@BabySagan Who knows. The universe is an amazing mystery. I don't think we're supposed to know it all. It's the never-ending journey that makes it so wonderful.
Harrison did a fantastic job! I shudder to think what sort of cosmic event might have resulted with Neil, Lord Nice and Harrison in the same room at the same time.
Can confirm, don’t put water on a molten candle! As a child my brother and I thought it would be a good idea to pour water into a tea light candle… how we didn’t burn the house down I don’t know 😀
In Michigan, we have a reservoir that when we have access energy, we pump the water from Lake Michigan into the reservoir, and then when we need energy, the water flows out of the reservoir through turbines to create electricity
2:16 We used Binary candles after a while. We only light the one bits. 8:45 The flame can not burn liquid wax that is why the liquid puts out the candle. What happens is the flame vaporizes the wax. It is the wax vapper, heat and oxygen that burns.
37:45 The conversation of fish, exactly. I have an aquarium that I am trying to make as self-sustaining as possible, but I still have to input light and fish food to keep it going. Although I could POSSIBLY get away with just light and air being added, because I have edible plant species that reproduce faster than non-plant species, but every day when I add fish food, there is a feeding frenzy. The key to this type of system, is that the larger and more complex the system is, the more the balances can swing to keep things going. So if you try to have a self-sustaining aquarium in 1 ml of water, it's going to basically be impossible. If you simply have a large outdoor pond that is below sea level and never dries out, it will be self-sustaining with life, because random things will be entering and leaving the water.
Also one more note: A self-sustaining ecosystem, doesn't mean all species in that ecosystem are thriving. If you want all desired species to be thriving, you have to do things to make sure they are (mostly food and cleaning).
most oil is from pressurized fossil remains of single celled organisms from long before trees existed such as diatoms (reference: Bill Nye circa 1993), what's your reference?
On the candle question. Neil talks about how the liquid wax, which is the flames fuel source, can put out the flame. I believe this happens when there is enough liquid to cut off the oxygen supply to the flame's ignition point at the base of the flame. Basically drowning the flame.
Wow, I was today years old (64) when I learned that being in a black hole would be survivable if it were big enough. Can only speak for myself of course, but I'd enjoy a podcast on that subject.
Black holes are literal holes in the fabric of space time and each black hole houses a new bubble universe. Each time you get enough stuff on a point in the fabric of space time, you poke a little hole in the fabric. All that junk falls through the hole, expanding a new section of space time like blowing air into a bubble with a wand. All the stuff in the black hole falls into the bubble and bam. New big bang, new universe. The great attractor is the biggest thing in all the universes that is weighing down the fabric. This is why the universal fabric will not rip and fail altogether. The overwhelming stretch and pressure is being relieved by the black holes creating new universes. I have no idea what I'm talking about but I had you going for a second.
Nothing at all against this gentleman , But , The information doesn't passionately stick well in my mind without chuck. I am perplexed by this fact, However , I have seen/felt this effect about 4 times , each time was without Chuck. Thank you ! Always so awesome.
26:45 I wrote something about this idea in highschool in 2010. I told the science teacher I had a theory on multiple universes being born from black holes and she asked me to elaborate on an essay. I never realized until now that there was something like this already
The saying "no nukes" became popular during the anti-nuclear movement of the 1970s and 1980s, particularly in the United States. It encapsulated the growing public concern about nuclear weapons and nuclear energy, especially in the context of the Cold War and fears of nuclear accidents like 3 mile island.

I think the take away from the plank question with the infinite question in mind, is that we likely vibrate because there's no end to time, and the space at which the object can get smaller is also likely infinite. So in an abstract way of thinking, our bits are rattling around unable to ever settle. It would be interesting if the vibration is the stretching of the universe on matter. If thats the case, we could prob notice the big rip coming if things started to vibrate faster like a string being pulled tighter.
Yea I remember when I got my tiny portable outdoor wood-burn stove a decade or so ago. You could also use tealight candles to heat stuff. So I tested, in my kitchen mind you, if two or three would get my morning coffee heat up faster, which it did. So I tried more and more candles.. turns out the whole thing was on fire at one point, I assume that was when it was so hot in there that not only the wigs where burning but also the wax. Was quite an impressive flame for that tiny stove. I tried to blow it out but it wouldn't work, so I placed it in the sink, away from other flammable material. But it would just not get less. I then tried to just pour the molten wax into the sink somehow and blow the rest out. Which actually worked. I spend the rest of the day pouring boiling water down the sink though, because the wax got solid again in the drain and it took ages of boiling water to melt it away down the drain.
So , growing up at a village in ghana withoudt electricity for years, so we use container with a lite to create light at night. Create a whole on the lite and cut a rag to create a wick . Stick tinny part into the lite and the rest into the container, pour kerosene into the container , cover and lightv the lite part , and times Square ,amazing. And that can go a whole month . Blow it off when going to bed. And light it following night for a month to refill
@StarTalk The issue I have (and always have had since first pondering the distortion of the fabric of spacetime by mass), is that describing it as a sort of rubber sheet (in the x and z coordinates), deformed by a mass (in the y coordinate), is essentially a two dimensional representation: if you think about it. The fabric of space time must necessarily be multidimensional (even though that is hard to describe), or else gravity would only work in one direction (as in the stretched rubber sheet model): which would no doubt make flat Earthers very happy. As for black holes, we always see them as if on a giant screen of stars, which we interpret as either looking straight through, or straight down the ‘hole’. However, that perception of the black hole would be the same from any point in space above, below, to the left, or to the right (for want of mathematical description). So irrespective of its apparent size, it ultimately compresses to a an infinitely small point. If I just had the intellect, another 70 odd years of life, an aptitude for advanced mathematics, astrophysics, and theoretical physics, I might just be in a position to write a paper to prove all this and get my own Nobel prize. As none of that is likely (or going) to happen, feel free to pick up the reins.
I like the description of photons as discreet packets. Because they are literally containers of nearly infinite energy that leak that energy all over the place.

i love having new guests! adds a new flavor to the episode! but there will never be another Lord Nice
Love me some star talk. Miss Chuck though.
Hey Neil, loved your parts on Big Bang Theory, especially the "Degrasse kicking" 😂😂
"If it happens at all, it'll happen 2B yrs from now -- I have it on my Calendar"... 😂😂😂
22B
Grew up in Hong Kong kids had a tradition of lighting candles in mid autumn festival. One night me and a few cousins were doing that near the lobby of the old apartment and somehow decided to threw all the candles into a metal bucket and light it all up. The fire got so strong the adults came out and had to smother it out. We got an earful. I've always been told that kind of fire is more dangerous than regular fire and now I know why.
Chuck, Chuck, Chuck!!!
This was a beautiful episode to listen to. It's incredible to listen to Neil speak off the cuff about things that are so profound. Compare this to politicians who can only ever read from a script. Really puts to shame.
We miss you, Chuck 😭 star talk just isn't the same without him
Not true.. Feel sad for the atoms passing through your body
A photon doesn’t really “know” how to move at the speed of light. A photon moves at the speed of light because it is itself light, and thus the definition of “the speed of light”. Photons will always go the speed of light, because they’re the gauge by which we measure them. Now they can be slowed in a medium, but whatever speed they are going is the speed of light in that medium.
It’s kind like saying what is the speed you walk measured in terms of the speed you walk at any given time. It’s always the same.
Redundant. Velocity is relative.
Corrections:
1. There is no such thing as "mechanical energy". There is only Potential Energy, and Kinetic Energy.. Taking the elevator up in a gravitational field, increases your potential energy.. Falling directly toward another object in a gravitational field increases your kinetic energy relative to that object, and hitting that object simply transfers your kinetic energy into the other object, producing kinetic energy in different directions (some of which is in the form of photons) which has mechanical effects.
2. Melted (liquid) wax does not need to be above the boiling temperature of water. You can drip candle wax onto your skin without being burnt by it. In fact, during candle making it is recommended to keep the temperature below 200F otherwise it can damage the wax's structure and color. If you raised the candle wax temperature up to the flash point (when its vapors burst into flame) then yes it is well above boiling temperature of water, but that's just a mistake, not a fundamental characteristic of melted candle wax.
3. Liquids (including candle wax) do not directly burn. They must first be heated until they vaporize into a gas, and *that* is what burns. A candle wick burning is an end effect, not causal. It is simply a vessel for liquid wax to be carried up to a point that the flame can turn it into a vapor and that is what burns. A wick only burns itself down when the level of the liquid wax drops far enough that it can't be wicked up in time to cool the wick itself (through the vaporization process).
Mechanical energy is the sum total of all kinetic and potential energy within a system.
@@Mr.Donahue Still makes it entirely meaningless in the context he used it though.
Great conversation, gentlemen.
Gratitude and respect.
Imagine being lucky enough to know 1/3 of what Neil knows. I have learned a lot from his videos. I always imagined astro physicists would be droll and serious, but Neil is the most upbeat scientist ever!!
48:00 many Solar storage "batteries" is pumping water to a higher elevation, and then using it as hydroelectric at night.
Aww man, you guys are sooo funny in OUR nerdy kinda way 😂😂😂
No Chuck this time, but my man Harrison had jokes lol
Yea corny jokes
@@An_Escaped_Mindbro lighten up.
47:00 Ah yes, as a Professor of Blacksmithing I loving calling the the Sun the Great Forge in the Sky.
Yes stars are great plasma forges compressing hydrogen into helium.,
@@randallbesch2424 And eventually some heavier elements, and if it goes supernova some even heavier elements yet! What I find amazing is there was enough hydrogen left over from the first generation of stars to light up and provide heat and light to a little ball of rock and water.
I've heard someone say that the plank length is not the smallest measurement , but it is the smallest measurement that can mean anything.
It all comes down to the Heisenberg uncertainty principle. If you would want to observe anything beyond planck scale the energy of the photon needed for such observation would create a black hole with the mass of Planck mass and Schwarzschild radius of Planck length.
I liked this guy! Funny commentary but kept his jokes concise. Sometimes I’m like ooooookay chuck…ok let’s go back to Neil now, we get it 😂. Love and appreciate both Chuck and this dude!
2:34 I'm 34 and still use candles. For my grandma's 74th .... We put 74 on that sucker
I love that
@Uttaela it was an inferno haha.
We did that to an stepmother-in-law when she turned 60. She did not appreciate that at all. Just to vain.
Neat
I celebrate nothing. The Earth orbits around Earth and I’m just along for the ride.
how do we submit questions?
First you need to become a patreon, and then something. I guess it's obvious after step 1.
Fire is made of fire 🤯
It's not a thing. It's a process
Fire is the outcome of a chemical process.
This would have been a great question.. look up phlogiston.... The search for this went on for centuries. What is fire made of.
I was a little skeptical until he brought Neil back on track lol then when he said "I thought you told the police it was an accident" I cracked up 😂😂😂😂
Yall need to calm down chuck probably does other things give the man a break. The important thing is you learn somethin here.
No.
@@paulo.8899they will not silence us! We want Chuck!
Neil's ability to ramble for so long without answering the question is actually fascinating
I'm 44 and I still have candles on my birthday cake 😅
Did you have 44 candles? Or just two 4 shaped candles? Was a fire extinguisher required? 😂
That's one way to tell yourself you're still young.
@@funkyhairman I think just a handful. I don't have that kind of lung capacity anymore! 😅
We ain't judging.
I'm 39 and basically don't even celebrate birthday.
When I was a kid, I was lucky to participate in a leadership course with the national guard. Part of the course was climbing a 32 ft light pole, and jumping off. The 1SGT said that the pole was 32 ft because if we fell at 33, we’d die. Thanks for the memory. 😅
Where is Lord Nice? I know he would have something enLIGHTening to say 😅
enWAVEring comment. 👏😜
Couldn't get through this . If harison could turn it down by about 70%, that would be great. Hopefully, I can come back to this another time.
Thanks for the video, guys. Super interesting
Miss chuck😢
Fine give others a chance and Chuck time to do his work.
Thanks for being my personal astrophysicist :D❤
I think we are probably mostly wrong about Black Holes.
Probably is correct. Can't even imagine really. Wonder if we are truly inside a black hole too.
@@BabySagan Who knows. The universe is an amazing mystery. I don't think we're supposed to know it all. It's the never-ending journey that makes it so wonderful.
36:29 the most unbelievable thing in this episode
Literally
Harrison did a fantastic job! I shudder to think what sort of cosmic event might have resulted with Neil, Lord Nice and Harrison in the same room at the same time.
Can confirm, don’t put water on a molten candle! As a child my brother and I thought it would be a good idea to pour water into a tea light candle… how we didn’t burn the house down I don’t know 😀
Most particles have an opposite manifestation. Do photons?
I am not Neal so i could be wrong but from what I read they don't decay so no there is not a negative photon, maybe 😂
In Michigan, we have a reservoir that when we have access energy, we pump the water from Lake Michigan into the reservoir, and then when we need energy, the water flows out of the reservoir through turbines to create electricity
I like this Harrison! Please bring him back, early and often!
6:04 since energy can’t be destroyed (only transformed) , is it fair to assume that photons are manifestations of energy too?
Yes, photons are a manifestation of energy.
What if a black hole is a rip in space time and everything is being sucked into it.
The Simpsons did it that way.
How great teacher he is i can easily imagine things he is explaining ❤
37:55 Neil, are you saying cannibal society is MultiLevelMarketing?
Brilliant!
2:16 We used Binary candles after a while. We only light the one bits.
8:45 The flame can not burn liquid wax that is why the liquid puts out the candle. What happens is the flame vaporizes the wax. It is the wax vapper, heat and oxygen that burns.
37:45 The conversation of fish, exactly.
I have an aquarium that I am trying to make as self-sustaining as possible, but I still have to input light and fish food to keep it going.
Although I could POSSIBLY get away with just light and air being added, because I have edible plant species that reproduce faster than non-plant species, but every day when I add fish food, there is a feeding frenzy.
The key to this type of system, is that the larger and more complex the system is, the more the balances can swing to keep things going.
So if you try to have a self-sustaining aquarium in 1 ml of water, it's going to basically be impossible.
If you simply have a large outdoor pond that is below sea level and never dries out, it will be self-sustaining with life, because random things will be entering and leaving the water.
Also one more note:
A self-sustaining ecosystem, doesn't mean all species in that ecosystem are thriving.
If you want all desired species to be thriving, you have to do things to make sure they are (mostly food and cleaning).
Watching StarTalk without Chuck is like watching Dallas Cowboy game without CeeDee Lamb. It’s just not the same😤
Almost ain’t worth watching you mean
Yo Neil DaGrass keep this W Thumbnail 😂😂
having no chuck is like having no neil :( shoutout to harrison tho
Mission: liking every comment not about Chuck.
Tyson did not say it bluntly, but the best description of the Big Bang Ive heard is: It's not an explosion in space, it's an explosion of space.
Everyone misses Chuck but I like this guy too
I looooooove me some star talk. i cant wait to be able to support the show guys. Love from Botswana (Africa)
I have to disagree with Neil (36:50) most oil is from dead Trees, before anything knew how to break down tree's materials.
Click your little timestamp and listen again. LiStEn.
most oil is from pressurized fossil remains of single celled organisms from long before trees existed such as diatoms (reference: Bill Nye circa 1993), what's your reference?
A tree….is a plant.
On the candle question. Neil talks about how the liquid wax, which is the flames fuel source, can put out the flame.
I believe this happens when there is enough liquid to cut off the oxygen supply to the flame's ignition point at the base of the flame. Basically drowning the flame.
No one is reading this comment section.
Don't bother.
Wow, I was today years old (64) when I learned that being in a black hole would be survivable if it were big enough. Can only speak for myself of course, but I'd enjoy a podcast on that subject.
Black holes are literal holes in the fabric of space time and each black hole houses a new bubble universe. Each time you get enough stuff on a point in the fabric of space time, you poke a little hole in the fabric. All that junk falls through the hole, expanding a new section of space time like blowing air into a bubble with a wand. All the stuff in the black hole falls into the bubble and bam. New big bang, new universe. The great attractor is the biggest thing in all the universes that is weighing down the fabric. This is why the universal fabric will not rip and fail altogether. The overwhelming stretch and pressure is being relieved by the black holes creating new universes. I have no idea what I'm talking about but I had you going for a second.
Nothing at all against this gentleman , But , The information doesn't passionately stick well in my mind without chuck. I am perplexed by this fact, However , I have seen/felt this effect about 4 times , each time was without Chuck. Thank you ! Always so awesome.
i exhausted 3 candles by the time Neil answered that 1st question.
Startalk podcast: I wish I had known that last week before driving from Denver to Meteor Crater. Thanks for mentioning it!
26:45 I wrote something about this idea in highschool in 2010. I told the science teacher I had a theory on multiple universes being born from black holes and she asked me to elaborate on an essay. I never realized until now that there was something like this already
at 26minutes when discussing we could be in a black hole, i've also considered this. Insane to hear someone else suggest it if even a possible theory
Great show nice job with the video editing!
The saying "no nukes" became popular during the anti-nuclear movement of the 1970s and 1980s, particularly in the United States. It encapsulated the growing public concern about nuclear weapons and nuclear energy, especially in the context of the Cold War and fears of nuclear accidents like 3 mile island.
Very very precious videos in today's world
Hi, kids from my school (Doral Academy) went to Los Angles for the XPRIZE competition to pitch their ideas on how to solve water scarcity and they won. They went with their robotics teacher and he is also my robotics teacher and he told me he met you.
It was this weekend
When I was about four years old, I used to think that the wind was caused by the trees waving their branches
If you ignite the fabric at the center of the candle while you're in the bathroom, you're an action star. Yes, John Wick.
This was a really fun episode, thanks to Harrison and Neil!
Edit: Neil, YOU ARE Magma P.I. you have the look of Tom Selleck already!
wow. finally a competent comedian. what a breath of fresh air.
Define "competent", Mr. Nobel 😂
@@Eons000 it might surprise you, but a competent comedian means minimally funny. the other guy was just stupidity n cringe. is he your friend? im sry bro
@CheckingYourRealityForYou How does that hurt you to such extent? Chuck has really dug a black 🕳 deep inside you 🫢
I think the take away from the plank question with the infinite question in mind, is that we likely vibrate because there's no end to time, and the space at which the object can get smaller is also likely infinite. So in an abstract way of thinking, our bits are rattling around unable to ever settle. It would be interesting if the vibration is the stretching of the universe on matter. If thats the case, we could prob notice the big rip coming if things started to vibrate faster like a string being pulled tighter.
Yea I remember when I got my tiny portable outdoor wood-burn stove a decade or so ago. You could also use tealight candles to heat stuff. So I tested, in my kitchen mind you, if two or three would get my morning coffee heat up faster, which it did. So I tried more and more candles.. turns out the whole thing was on fire at one point, I assume that was when it was so hot in there that not only the wigs where burning but also the wax. Was quite an impressive flame for that tiny stove. I tried to blow it out but it wouldn't work, so I placed it in the sink, away from other flammable material. But it would just not get less. I then tried to just pour the molten wax into the sink somehow and blow the rest out. Which actually worked. I spend the rest of the day pouring boiling water down the sink though, because the wax got solid again in the drain and it took ages of boiling water to melt it away down the drain.
Usually I don't comment & just leave a like but this time I will.
What made you comment this
So , growing up at a village in ghana withoudt electricity for years, so we use container with a lite to create light at night. Create a whole on the lite and cut a rag to create a wick . Stick tinny part into the lite and the rest into the container, pour kerosene into the container , cover and lightv the lite part , and times Square ,amazing. And that can go a whole month . Blow it off when going to bed. And light it following night for a month to refill
Cool. You answered questions I hadn't thought to answer yet. Thanks.
Really love the cohost! Love you too Chuck!
I wish Harrison would’ve dig deep and said Galactic Gumbo! Def Miss Chuck, but he did a good job trying to fill those Lord-size shoes
@StarTalk
The issue I have (and always have had since first pondering the distortion of the fabric of spacetime by mass), is that describing it as a sort of rubber sheet (in the x and z coordinates), deformed by a mass (in the y coordinate), is essentially a two dimensional representation: if you think about it.
The fabric of space time must necessarily be multidimensional (even though that is hard to describe), or else gravity would only work in one direction (as in the stretched rubber sheet model): which would no doubt make flat Earthers very happy.
As for black holes, we always see them as if on a giant screen of stars, which we interpret as either looking straight through, or straight down the ‘hole’.
However, that perception of the black hole would be the same from any point in space above, below, to the left, or to the right (for want of mathematical description). So irrespective of its apparent size, it ultimately compresses to a an infinitely small point.
If I just had the intellect, another 70 odd years of life, an aptitude for advanced mathematics, astrophysics, and theoretical physics, I might just be in a position to write a paper to prove all this and get my own Nobel prize.
As none of that is likely (or going) to happen, feel free to pick up the reins.
I like the description of photons as discreet packets. Because they are literally containers of nearly infinite energy that leak that energy all over the place.
