Spiders eat spiders. Often their children, mate, parents...depends on the spider. Might just be the bear equivelent spider eating a mouse equivalent spider.
Since I was a kid I always thought the droplet drinks on the bar scene in "A Bug's Life" fascinating. I'm so happy it's scientifically accurate, haha. Thanks for the awesome content Neil, Chuck and everyone else involved.
i learned the weight and size and strength stuff in a basic algebra course - and the instructor used it to prove why giants (how we imagine them to be) couldn’t physically exist. that was probably 15 years ago, and i still remember that lecture.
That would only occur if you're moving at speeds nearing the speed of light. If you're referring to the galaxy sized being and it's reaction time then yes, but he did mention that.
Completely agree with Dr Tyson on the limits part, especially for mammals. There is a law called Kleibers Law :which has physical roots in biology of mammals.
@Aditya Pratap Singh I passed out in 1999 in Chemical Engineering. I had two papers in Microbiology. Further, I have competed courses in Animal Welfare, Astrobiology, Brain Chemistry on Coursera in near term (for HR minded questions : previous 4 years). So, I think it gets me enough credit to comment on this topic. Further, I quote The American boy learns unspeakably less than the German boy.Inspite of an incredible number of examinations, his school life has not had the significance of turning him into an absolute creature of examinations,such as the German. Max Weber
@Aditya Pratap Singh You asked me about NEET exam. I am active out of sincere interest and not specifically for an exam. If we pick subjects for our exams : for example people pick anthropology and psychology for UPSC exams, as they are easy to understand and get marks, instead of maths or Physics. That person is a "creature of the exam".
Love this conversation. My question: If a human were born in zero gravity , out in space somewhere, in a spaceship at constant velocity, how big would an individual grow ?
Possibly not much at all, even in space astronauts tend to lose muscle weight because the body, being an adaptive living thing, detects that very little strength is needed to do all things and small muscles work just fine. Besides this is mostly determined by genetics, gravity did its work during the evolutionary natural selection.
This episode was about a repeated topic that they did talk about already at least a half a dozen times along with surface tension. Of course Chuck doesn’t remember any of it.
@@nirabhradas6375 It's really more like a 5th-power/4th-power law, when it comes to the strength of bones in large mammals. Because the failure mode of buckling matters more than the failure mode of direct rupture. Buckling scales with the square of the length of a structural member in compression, and weight scales with the cube of linear dimensions. So on net, the potential to buckle scales with the 5th power of your linear dimensions. Resistance to buckling depends on the Young's modulus and second moment of area of the structural member. A property of geometry, that is analogous to moment of inertia, and often called that as a misnomer. This property scales with the 4th power of the linear dimension. If you consider two otherwise-identical solid rods, one twice the diameter of the other, the larger rod will support 16 times the load, before it buckles.
Not specifically to the episode but advertising material often shows a 3d bar chart or pie chart comparision, when 2d is appropriate. The 3d tricks us because we see the volume of the bar chart when in fact we need to see the area in 2d, thus, deceiving us to make differences larger then they are.
"The fly" is a more accurate film. Or a true spiderman would look like the xenomorph from alien a little bit. But also spider-woman would be twice as big, five times as strong and prob eat him.
1-1-1 2-4-8 3-9-27 4-16-64 5-25-125 6-36-216 7-49-343 8-64-512 9-81-729 10-100-1000 - Just to emphasise Neil's point about how rapidly the cube of a number diverges from it's square.
Alex Honnold is the name of the climber Chuck was talking about if anyone was curious. He completed a free solo of El Cap in Yosemite. The movie is appropriately named “Free Solo” I encourage everyone to watch it and get a dizzying dose of vertigo.
Hey Neil, at 13:50 you veered into the "sailboats on Jupiter" fallacy assuming galactic-sized life has human issues and limitations. Otherwise loved it.
All physical matter in the universe has limitations. Those are the limitations set upon all life, including hypothetical life at this time because we have nothing else for reference. To presume physical laws would not apply to other life within this same universe is quite a bit short sighted, and is the reason why the attempted correction was flawed from the start. Remember, you are failing to correct a person with much more education than anyone found in these comment sections. Chances of failure are rather high given the topic. Now, sure. There could be life which has learned how to bend physical laws at will. But until we have evidence, we must consider that all life is tied to the very physical laws of which we are tied.
@@Phantom-bh5ru I am extremely sure of the physical laws which govern the entire universe. That includes any possible life. Assuming there is any, just because life exists elsewhere in our universe does not negate those laws in any way. All physical matter is tied to those laws. To presume otherwise is short sighted.
@@Phantom-bh5ru Well, I opted for a much politer word to be truthful. I wanted to use the words wrong or intentionally ignorant. But those terms do not really apply here as much as not seeing the bigger picture does. And that bigger picture is, physical laws are just that. Laws. There is no altering them to fit a hypothesis. It's called English. And in English, many words have ulterior meanings. Short sighted can mean one is not seeing all of the information, hence why it was used here and not some other more insulting word(s). His "correction" was incorrect from the start due to not considering all of the information. I.E. Short Sighted. Or "wrong" if you will.
I believe the climber Chuck was talking about is Alex Honnold. The film is most likely Free Solo, which documents Alex's ascent of El Capitan in Yosemite without safety gear. If you're bored, watch it!
Darkness is merely the absence of light. Matter can exist without light. While there is no calculation for the absence of light, light itself does have a calculation supporting it. If you are talking about before there was matter and energy, you might as well use a big 0 because all physical laws break down at the initial point of expansion. (big bang)
Hmm you can measure how much a body radiates or reflects light. They say black-body even if its a bright star because it doesnt reflect. But if you want to measure how black an object is thats positive amounts of absorption and not a nothing its absorbing all the light.
@@jorgepeterbarton okay but like the universe is expanding what’s that space beyond the universe like right before it comes into our existence, what is that nothing that our universe consumed, what if 3D is what we see the line is 4D and outside is a 5D with laws of physics we can calculate yet? Because we can barely describe the line 🤯
Man! I actually thought you had changed your camera equipment for this one because the B drops are pretty neat. Until I saw the iPhone in driver’s mirror
It’s Jesus Lizard a basalisk, and it does have wide feet. But would someone tell me why paleontologists think that a pterasaur ten times the size of any modern flying creature can not only fly but at very high speed. I would think that the power to weight ratio could not be one tenth of any modern bird.
Neil, I really love hearing from you👊😂...wish you could interact with us little bit more often on the comments...But I Know you're busy "Astrophysicing"😂😂😂 it's okay!!!❤️
It's not so much that he is busy, which he is. It's more the fact that he has no involvement in the social media accounts. Paid "admins" from different countries operate those accounts. Basically, we are not necessarily talking to the man himself. lol
This is only describing a system where atoms stay the same size. If we somehow where able to create a giant ray that while increasing your size, also increased the size of the atoms that make up your body, you would still be quite fine. If I am not mistaken, thats how things like Antman are explained in comics.
Simply changing the size of the atom and all its elementary particles is not enough, you'd still have to change the laws of physics otherwise gravity would continue to interfere, in essence it would be much functional to just increase the number of atoms to make a bigger stronger body.
@@SergioCastillo87 not exactly. Since this is not possible(that we know of) you cant really answer how gravity would work on atoms that are bigger than normal. If you think about it, the mass doesn't change. a billion atoms is a billion atoms. it theoretically work that atoms that are 3 times bigger still have the same mass as the atoms three times smaller and thus gravity interacts with it in that way. They atoms would just take up 3 times as much space. But this bring up other issues because if you are the same mass how would your body interreact with mass made up of smaller atoms. Just because your the size of a sky scraper, you would still only have the mass of a normal 6 foot tall human.
@@tidus9942 But then when you say increase atom size you're not talking about it's particles only of the volume, thus the orbital distance between the electrons and the nucleus, in essence you're only stretching the atom, we can then theorize how it would behave, the electric force of such atoms would be greatly diminished, the body wouldn't be able to sustain itself collapsing in a rain of electrons, that's why i mention that you'd need to increase the size of all particles as well in order to increase their mass and generate a stronger electric attachment to prevent collapsing. But again, none of this would be possible in our universe and wouldn't make sense, but as a brain exercise is fun...
yep. I work at a museum and we have a gecko in our animals area and there's a reason the gecko can attach itself to the side of the glass enclosure. I believe the force is called the Van Der Waals force.
I like rivers but I choose highways because they are faster. But you’re right. Life is like the choice between a highway and a river. Thanks for your poetic analogies. Very creative.
FACT: Interruptions take time. To present, to explain, to allow for laughing, etc. Regardless of whether interruptions are respectful or disrespectful to various guests, they still take time. Time that could be devoted to more "science". (what is the popularity: the knowledge or slapstick ?)
Even if i know that neither of those 2 guys will answer, or even take the time to read this comment, i will still right it... Massive heavy body animals with skinny legs: Horses Mooses Camels Girafes ...
Their mass is nowhere close to the mass of the animals mentioned in the video. Their mass is much less, therefore they can have smaller diameter legs. And even if they do not see the comment, those running the social media accounts are paid or at least motivated to go through the comments looking for questions for future episodes.
Is the surface tension "water blob" concept related to why craters are circles? For instance, as the blob's volume increases, so does it's mass. Therefore, eventually the Mass x Gravity generates a higher amount of energy than Molecular Energy of the blob...which _could be_ why the blobs can be much larger in a zero gravity environment. How far off am I on this?
@@princeofallnegros4035 - I totally agree. Science is cool enough and not everything is a joke. I take science seriously. No need to joke about it every minute.
He is mistaken a lizard with an insect. Is called green basilisk and it is also known as the Jesus Christ Lizard.ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-leSN6WI1KwU.html
So molecules are atoms grouped together. I always wonder if maybe atoms are also made of something even smaller. I mean after all we can split them, so it must be made of something right? We just dont have the equipment to measure anything smaller.
The word you are searching for is Quarks. I'll copy and paste because my answer would not be as easy to understand. **A quark is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. All commonly observable matter is composed of up quarks, down quarks and electrons.**
When a whale is in the water...gravity is pulling it down and the water is pushing it upwards right? And since weight=mass*gravity, how is the water playing any role in the weight of the whale? Can someone please explain this to me?
I have another question... the specific gravity of water is 1, so do you do, wieght=mass*1 (gravity), if the specific gravity of water is 1, shouldn't weight be equal to mass? Correct me if I am wrong, thanks.
I've one question here. Ants take more time to reach from point A to B compared to human. If ants or any micro organism imagined that life at human size cannot exists just because it would take lot of time to scratch a head on that level from their perspective, however we still exists right ? Then why cannot the life at universe level (light years) exist ?
Life could still exist, it just would be completely different and time for it would run much slower even. For example, what is life? How do you define life? Something that is capable of being born, feeding, growing, reproducing and dying? Some may argue that stars are a form of life under this definition, same as black holes... but if we are talking about some kind of carbon based biological life then it would definitely be limited.
Could a galaxy sized life form exist with distributed or multiple brains? ie have distributed thought and control process that can consume nutrients for the whole without needing to report all the way back to a central brain? Some kind of central brain could conceivably set the overarching goals/direction of movement while distributed secondary/tertiary brains control independent local functions. It woulnd't even need a particularly large biomass relative to its size as it could take on a jellyfish-like form with long tendrils
Well, if it applies to hippos, it applies to any and all land based life. In fact, the rules which apply to all land based life was expressed in this video. Have you not taken a look at a cow's legs? They are MUCH larger in diameter than a horse. Also, remember that their mass is much less than say a hippo's mass. As a result, their legs will be smaller than a hippo's legs will be.
It's all about the tone Chuck "Uh ohhhhhh" in a happy tone is the same as "Okayyyyy" in a happy tone. It means exactly what you said. I'm excited or intrigued.
Picoplankton size is less than 5 micro meter. However the world's largest molecule PG5 is 10 nano meter. So as Dr Tyson says, there is no sub molecular life yet. Till they synthesize or find a larger molecule or a smaller life.
Another way of saying this is that if Spider-Man had the strength of a human-sized spider, he would be roughly as strong as a regular person. Edited: Neil ended up saying it in the end. LOL
