  • Where can I get a flashing institute of physics ball?

  • what am I going to do , Ive almost watched all the sixtysymbols videos !

  • At 4:32 you say "the average density of mars and earth are about the same." In fact mars is 28.6% less dense to be precise. That's not "about the same."

    Other than that ...I liked your video.

  • @MegaSkills9 For the purpose of that demonstration, that's obviously accurate enough.

  • how do we actually know the mass of the object that is causing the lensing? there's so much stuff in space it all would have an effect on light, can we really find just one source for the light?

  • how can you tell how far it has been rotated, by how much light is polorized in particular directions?

  • @masluxx

    Are you referring to something in the video?

  • @dudejohnny did you watch the video? The bit at the end talking about lensing? the mass of the star doing the lensing would dictate how far the light was bent. The mass of it has to be assumed, how ever gravity would shift the polorazation properties of the light and that you can measure dirrectly.

  • @masluxx

    I don't think it would change the polarization of light, but then again I wouldn't know. It doesn't seem intuitive to me

  • You guys should sell the Bill Nye cards I would so buy one.

  • Please rename this video to "how to fist a couch".

  • sooo is it an optical illusion for the person on earth looking at the light from the star thats being deflected by the planet, and if so how do u know its an optical illusion is that because of Einstiens equations?

  • @dmanz007 You can normally tell it's lensing if you see two identical stars in the sky. Otherwise, you can sometimes tell if the planet causing the lensing moves, it will change how the light is bent and hence how we see it; a bit of detective work can then tell if it really is being lensed. And I'm not really sure you could call it an illusion, but I guess thats just semantics.

  • If you don't like people responding to your opinions, don't voice them :/

    If you do state your opinion, you must be aware that people might not agree with it, more, they can even challenge it.

  • "VVe don't have a full theory.", "VVe don't understand this.", "VVe are not sure vvhat causes that." This is the trough of science?. If they don't undertand anything hovv can they teach society? So little knovvledge, and yet such big ego's. Too afraid to assume, and yet so quick to judge. Need to look at the big picture before you disect the canvas. Step back, look at everything and you'll see that everything is connected, everything is related, everything is one. Doesn't take a genius to see it

  • Comment removed

  • @projectmoses69 "Need to look at the big picture before you disect the canvas. Step back, look at everything and you'll see that everything is connected, everything is related, everything is one."

    OK, so everything in the universe is a part of the universe and things interact with each other. Isn't it like, common knowledge?

    "If they don't undertand anything hovv can they teach society?"

    You are confusing not understanding certain bits with not understanding anything.

  • @RezoJaco One thing I dislike are literal cops. People vvho sit back and disect other people's comments and vvho feel they need to correct other people's opinions. if you are not satified vvith my comment on the subject matter, and require a more detailed explanation please feel free to study my video series. I vvould then be happy to ansvver any questions you may have as long as they are sincere. I believe the cure for ignorance is listening to other opinions and nevv idea's.

  • @projectmoses69

    Have you lost the "w" key on your keyboard?

    Cus that would make it very easy to make you jealous, look:

    wwWWwwWWwwWWwwWWwwWWwwWWwwWWww­WWwwWWwwWWwwWWww

  • @wybo2 LoL,VVvvVVvvVVvvVVvv ya it's definately broken, have to use double v's. one of the kids broke the key off.

  • @projectmoses69 word salad and total nonsense. Why don't you tell us all about gravity then seeing as you have this amazing insight

  • Comment removed

  • @Juxtaroberto Based upon analytical logic there's a 99.99% chance that you're a Edomite & I'm correct.

  • @Juxtaroberto That "medium" you're not considering is the very same indigenous E = m the physicist(s) view as & call dark matter ± dark energy (+dr (+dt (+t Δ -t) -dt) -dr) that's in this 1st dimension (d¹) & forces nonnative Big-Bang E = m to coalesce, etc & neither of them is "dark".

    + (±) - ≡ ⁺∞ (±) ⁻∞ ≡ +F (±) -F, etc proves they're pressurized.

    They both consist of a transparently unilluminated E = m relative to the Illuminous E = m & identical to Neutrinos it's not impeded by normal E = m.

  • @Entrepreneur101 All I can say to that is

    WTF! Can I have some of whatever it is you're smoking please

  • Why are there so many penis videos to the right...

  • ok, ok, I just had a brain lock, if an observed object in space is under the effect of a gravitational lense, but you only have one image of it, how can one surmise it's original position without knowing the force of gravity of object doing the "lensing" ???

  • @ZenSpider40 Yeah right.? I thought about that too.! I do not know the answer but the only way I see it comprehensible is this way:

    You have an object in "A" but you see it in "B". The most reasonable way to know that, under my point of view, is because you see the object deflected all the way from "A" to "B".

    If it is not like that I really would like to know it, thank you.

  • 5:34 According to physics, physical law(s) &, or analytical logic the term "spacetime" is 100% incorrect since it's based on the universal lie(s) that the Big-Bang created space & time. The act of gathering the E = m material(s) to build your house, etc do not create the location (e.g., dimensional space) that your house, etc will be built in.

    The term "dark matter &, or dark energy" is 100% incorrect since it's not dark & trying to measure their mass is impossible as comoving distance proves

  • @Entrepreneur101 So that means you must be smarter than all of the physicists on Earth, because you, with all of your vast knowledge, have clearly come across a discovery that all of their feeble minds could not comprehend! Oh wait . . . .

  • @bodinian Yes I am.

    (How come you might ask?) I do not subscribe to any of Darwin's nonscientific & non-mathematic evolutionary delusion(s) however 99.99% of all physicists, geneticists, chemists, etc do.

    And your species wallows in & adheres speaking lies, in which is already exposed & delineate using the secular (i.e., science & math) tools of your species.

  • @Entrepreneur101 So, you are a creationist on a video about the gravity constant?

    I smell a troll here.

  • @bodinian I am nonpartisan, nondenominational, impartial & unbiased TRUTH arbitrator.

  • @Entrepreneur101 I stand corrected, start a university, I would attend

  • @bodinian impartially & unbiasedly speaking I thought you knew that, the institutions of (alleged) higher learning is nothing more than conduits, or portals for indoctrinating 99.99% of all attendees with Darwin's nonscientific & non-mathematic evolutionary delusion(s).

    E = m is actually complexity (e.g., E = m ≡ m = E) that may be look at as being simple, but it's not.

  • @Entrepreneur101 Wow, conspiracy much?

  • @Juxtaroberto Since I am logically analytical &, or a bibliotist, I say...

    FYI: It's a well known Biblical, historical & global fact that, your Satanic Edomite species pride themselves on how many scientific, mathematic, spiritual, governmental, sexual, etc lies that they via their father Satan (or, the father of lies) can speak &, or get others to believe too. A partial-list is below

    ● Black holes destroys E = m

    ● The Big-Bang created space & time

    ● Sound do not travel in the vacuum of space

  • @Entrepreneur101 I can understand how someone who does not have a degree in physics would not understand the first two, but the third one puzzles me. It takes a deep and severe lack of knowledge of classical mechanics to think that last one is a lie.

  • @Juxtaroberto As a physicist, geneticist, chemist, etc I say...

    Edomites (or, so-called white people) naturally wallows in (nonscientific & non-mathematic) evolutionary Darwinian delusion(s) just like the imbecile Stephen Hawking.

    I watched a show he did on the discovery channel (i think) & he visually & audible said that, time traveling & time dilation was the same thing, he said if you got on a train capable of v/c momentum went around the world, when you got off things will look different.

  • @Juxtaroberto Your comment(s) is a declaration that on your very best day you're a laymen &, or ineptly incognizant.

    FYI: Sound waves is another form of E = m which consist of Protons, Neutrons, Electrons, Gluons, etc therefore if I were to view your comment(s) & apply it relative to physics, physical law(s) &, or analytical logic it will be equivalent to you saying Protons, Neutrons, Electrons, Gluons, etc do not travel in the vacuum of space either.

    I suggest that you stop using the drug(s).

  • @Entrepreneur101 No, no, no, that's all wrong. When the energy associated with sound travels its medium does NOT travel with it. There are simply compressions and rarefactions of the medium but NO NET MOVEMENT. You need a medium for sound to travel through... the thicker the better. THERE IS NO MEDIUM IN SPACE. You are OBVIOUSLY neither a physicist or geneticist or chemist, etc.

  • @Entrepreneur101 Also, I'm not white. So your racial profiling of me falls flat on its face. Moron.

  • @Entrepreneur101 I do agree with you on the point that the English language does not make sense sometimes, though. I am being honest about that part.

  • I love the sofa space-time example. I'm totally stealing that and using it.

  • Why the Einstein's cross is a cross but not a ring?

  • @TheDingiso

    That's a very good question.

  • @TheDingiso

    Ha! Watch to the end of the video. There it's been said that the ring requires perfect alignment.

  • If you dug out a wee spherical hollow in the very centre of the earth and reinforced it enough, would anything happen to an object inside of the hollow?

  • Comment removed

  • @TheFutileFetus Let's assume that the Earth has a spherically symmetric mass distribution. Then nothing would happen. If we put a particle anywhere in the hollow you described, and then measure its gravitational potential energy using Newton's law, we will get a value independent of the particle's position. Thus, if the particle moves around in the hollow, the potential energy remains the same, meaning no gravitational work is done on it, so the gravitational force is 0.

  • Comment removed

  • Gravity has no particle to carry the force, because it doesn't need one! Gravity is the effect of mass! And mass makes space-time itself to fall towards the mass! So think about it! When you fall, you're not really falling, the space itself is falling, and you get only transported by the space!

  • @danielbluesmoke Think about it. The normal analogy of the "fabric" of space-time is just for people to understand the concept. Space-time isn't really a fabric, and mass can't "fall", bending space-time. You need a boson to actually cause an effect on space-time. You must break out of the concept of space-time "bending" as it isn't. Fermions can't interact with space-time.

  • @danielbluesmoke Yes, but if the photon has taught us anything it's that sometimes things have duality. Photons can act as both waves and particles. Electrons too. We should keep am open mind to the graviton.

  • Fist F*ck My Face In Ass 4: Staring Woman physicist

  • Measuring the angle of bent light to calculate mass... brilliant.

  • @ispravljat I don't see the connection between those statements... A basic look into special and general relativity will show that the closer you get to a massive object the slower time is. As a wave passes through the surrounding space it is bent because the part of the wave that is closer to the object is moving slower than the part farther away. In essence, it causes a bend in the direction of light, relative to the object. Simply put, that is how it works. Do you understand?

  • @ispravljat Light is both a particle and a wave. Sometimes it behaves like the "stuff" in your microwave that makes things hot, sometimes it behaves like the grains of sand fired through a sandblaster. Gravity's effect on light falls in the behaviors associated with the latter. Far too much to fit in a YouTube comment, though our high school physics class learned all about it.

  • @ispravljat well, yes, it's quite hard to imagine, but that effect have been observed by observatories around the world. And, by the way, flat earth was a good theory back in the days - it served it's purpose (we still use it for local practical purposes), and present science too, presents only theories of how world works - no real scientist would say that there is a 100% accurate theory - there's no way of knowing that. At least yet.

  • Comment removed

  • "So, we go back to my fist here.." - You just have to love physics..

  • @appelelle The third time she called the attention on her fist I felt a little intimidated (my little g actually) *chills*.

    Jokes apart, this whole series is awesome!

  • Could we bend the light emitted from our own earth around a number of planets or objects, so that we could see it with a telescope? And if so, would we not view our own planet back in time?

  • @qkn30989 Yes, I suppose you could. The distance it would have to travel to actually double back around to it's source would be phenomenal though, given that we can just barely see (often not with visible light) massive planets orbiting other relatively close stars that would pretty much make it useless.

    There is also the problem that the light would become distorted as it bent around so many sources of gravity, and the natural dispersal of the light eventually completely nullifying the image.

  • @qkn30989 NO. Light doesn`t orbit a center of mass, a material object does.

  • @LeconsdAnalyse She quite clearly says light from behind such heavy gravitational objects does bend light, and that we sometimes can see light from one planet bendt all around said objects.

    But you might know better than I do, I'm just curious =)

  • @qkn30989 YES. That`s true. She is correct. But your original question is another story.

  • Awesome video, especially there at the end.

  • would a gigantic poo be attractive?

  • @sikhfukk yes

  • The scientist from 5:35 to 8:00 Basically explained 2 weeks of studying in my school and discussing the big G and the effect of gravity on other things...

    Big kudos to her, she's really great..

  • Should we let our own imagination take control over how we see things or should we let facts and observations take control of how we see things? That is my question to all creationists and darwinists.

  • @Wacram Why Darwinists?

  • At one point you say, (around 1:10) that you have a calculator with the constants built in..

    Can you tell me what the calculator is, make/model or anything, an/or where to get one.

    THANKS GUYS KEEP UP THE VIDEOS !!

  • @rizzdrums4life It's also possible that he's talking about some sort of calculation software on his PC.

  • @rizzdrums4life I of course have no clue about the calculator referenced here, but the Hewlett-Packard's HP-48 had this feature 15 years ago. I'm sure there are other HP models that also do, and probably some Texas Instruments scientific calculators as well.

  • @rizzdrums4life my $20 Casio has them built in as does my $200 HP-50G you pay your money and take your pick. Go for the HP, you also get the benefit of working in RPN

  • g=GM/R2

    F(g) = GMm/R2

  • "Big G" sounds like the name of a pimp.

  • @eggroll9000 oh but it is.. get on its bad side and you get an ultimate bitch slap... its called FAAAAAT!!

  • F = M1M2G/r^2

    g = (m2G/r^2)

    F = M1g 

  • Longest intro evar.

  • If photons have no mass then why is light deflected by gravity?

  • @soppybollocks11880 gravity as described by the video can even warp space, which is a vacuum (light travels at different speeds at different atmospheres we only get the constant when it is in a vacuum), so why can it not warp light?

    thus in layman's terms

    gravity > vacuum > light

  • @soppybollocks11880

    Photons have mass, they don't, however, have any rest mass.

    As the particle moves it exhibits energy and from E-mc^2 we can see that energy is directly proportional to mass.

    This shows us that photons have mass in motion.

  • @soppybollocks11880 There is no distinction between mass and energy in the light of general relativity. They are just the same thing appearing different from different frames of reference.

  • Nobody's gonna believe me, probably, but I imagined gravity exactly like in that analogy with that sofa's cushion (except in my mind it was a trampoline thingy xD) without even knowing it was the actual model for gravity. Of course it didn't just pop into my head, I'm no genius... I got the idea after reading an excerpt from Flatland, and then hearing some guy say gravity was a curvature in space-time. It was neat and frustrating at the same time when I learnt "my" theory was made 50 years ago .

  • why is it such a close up on the first guy lol

  • I will be sure to show my girlfriend this video, she is always demanding me for a big G!

  • prety chick...

  • my GF said i need to find her G-spot... but this didn't seem to help at all

  • Yes the ‘’G’’ is very important.

    I need to find the ‘’G’’ spot for my ‘’G’’f and after I am done she sais to me ‘’G’’ood job and I feel very ‘’G’’ood about myself.

    All the important things in life start with a ‘’G’’, Glory , Gold, God, Guns, it’s in an equation in the world, some countries have lots of Guns others have Gold so the Guns steal the Gold and the once that lost the Gold pray to God for Guns and the once that have the Guns and the Gold live in Glory.

  • I think she's motioning for me to sit on that representation of space time next to her?

  • this video sums up evry ting i think about fellow humans 

  • She's rather skilled at fisting.

  • now when i see two identical looking stars i will know what is really going on

  • so does that guy always carry that card and that black marker because in every vid hes in hes always writing with that thing O.o

  • If only Einstein had the power of PCs today...

  • I read somewhere that Galileo never actually dropped anything from the Tower of Pisa! Instead, he looked at how different sized balls of different materials rolled down a slope and from there he deduced that gravity acted upon everything equally.

  • Thumbs up for the female physicist ! whoop, looks like my secondary school physics teacher !

  • these physicists are proper inspiration! dont ever stop making these videos.

    makes mne want to to go to uni of nottingham.

  • This is what the discovery channel should have been like, +subscribe for you

  • how awesome this vid would have been if they only explain what would happen if G happened to be any other value, say 3.5e-7, or 6.67e-12 or something...

  • Does that work in some way with the clouds and the moon? Twice I have seen a perfect circle of cloud with the moon in the centre and it couldn't have been random, how could it have been perfect from where I was standing. The only problem is that the clouds are in front of the moon.

  • @BULLBRANDDAN Errr, no... the clouds were probably just thin enough that the moon could shine through.

  • @BULLBRANDDAN It's actually just the light of the moon (which is the light of the sun) refracted through either ice crystals in the atmosphere, or moisture in the clouds, much like a rainbow after a rain shower.

  • @BULLBRANDDAN: As the others here say, what you're seeing is the light bent not by gravity but by refraction through ice crstals in a very high, thin cloud. Go to wiki and look up "moon dog". The moon does bend light but since it is much less massive than a galaxy, he bend is too small to notice.

  • GRAVITY cat not amused

  • What's her name? Love her explanations!

  • I propose: What if gravity is a property of space just as time is. It isnt a particle. And so are other fields - like magnetic fields. I see gravity and time as being connected.

    I see gravity as the warping and twisting of space due to matter. However it isnt a one-to-one relationship. The more matter you cram into a space - the gravity 'warp' is logrithmic and can be inifinite.

    Dark matter is space twisted and distorted on itself for some reason and not really matter at all. What do you think

  • @shagster1970 It's possible. However, the Standard Model has predicted the graviton (which, although I am not sure, might also be the Higgs boson), and all its previously predicted particles have been found. A theory's predictive power gives credence to its validity.

  • good work predicting so many stuff einstein .....

    now thats what i call a prediction , not some cheap lady with a crystal ball telling me my future :D

  • lol 1:43 "I'm partial to gravity."

  • getting paid by making stories lol! what a nice job.

  • This is why I will never get the Einstein view of gravity...

    2D model sounds good but space is 3D...

    Hard to wrap my head around that...

  • Well, you just take each case of gravity between 2 objects on the 2d plane win which the centres of mass occur,

  • 2d plane curves in 3d ..

    3d plane curved in 4d ...

    and so on ..4d space curves in 5d ....5 in 6 ...6in 7.....bla bla ...10 in 11 the end.

    impossible to imagine ....but thats how it happens ...

    string theory brings a better explanation ...but i cant say it ...i can barely understand it.

  • I still dont get the fist on the couch - gravity warping space - analogy. Her fist warps the couch instantly - but warping space/time occurs at a finite speed (c I think). Isn't there a better analogy?? Also like the ball - the light would speed up as it nears the object. This seems to be impossible.

  • it does occur, i'm not sure when the next time this will be observable is, i remember seeing a simple, large home telescope with a distant image of Jupiter, as it passed near the view of a star, and right before it contacted (visually) the star, the star apeared to move. Videos of this with the sun are on youtube durring an eclipse when u can see the relativly dim stars behind the sun.

  • @shagster1970

    That´s one of the pickles of gravity....its effects are instantaneous.

    If the Sun disapeared, you would know it ~8 minutes after because the last photon that the Sun emited would take that long to reach the Earth.

    But the Gravitational effect would be instantaneous, meaning that when the Sun disapeared the Earth would immediately start to drift out of the solar system because of the centrifugal force of our orbit around the Sun.

  • Wait - you said the gravitational effects are instantaneous. How is that possible? If it is a particle ("gravitron" is used in this movie) - nothing travels faster than light (as far as we know). I guess it comes down to: what is gravity????

  • You can travel faster then light by using gravity. If you could generate gravity (which we cant do-even though we are working on it) You can pull space to the craft and move through space that way.

  • In order for that to work you would have to be able to produce gravity that works in only one direction. Plus to generate a force that would pull oh lets say the next star closer to us, would require massive amounts of energy or a massive amount of matter.

  • actually thats how the universe expands faster than light ..the objects in the universe dont move faster than light , its the universe itself that expands faster than light ...

    no object can ever go faster than light , that would literally mean u go backwards in time ...wich doesnt make any sense ...it doesnt even work with interdimensional theories ...

    distant galaxies are receeding faster than light but they dont actually move at light speed , hey even nature can cheat the speed limit :)

  • oh and no way to generate that kind of gravity :)

    it would be much easier to use curved space to "beat" gravity to a location by taking an extradimensional shortcut..

  • No no no no no!!! All effects due to changes in mass would radiate at the speed of light.

    As I understand it (which isn't very well), fixed masses interacting (such as planets in orbit) have several relativistic effects going on which almost cancel out and give a net effect very similar to instantaneous Newtonian gravity. However, CHANGES in gravity, caused by a changes in mass, radiate at the speed of light.

  • You are right, i´ve read some more things and by the General Relativity Theory its ~ the speed of light.

    But i´ve seen that on a documentary (dont remember the name) and i remember it because it´s counter intuitive acording the laws of physics that we know, so in that regard thanks for correcting an old and corrupt data bit on my memory ;)

  • @Micr0chiP no it wouldn't, it would take 8 minutes no information can propagate faster than the speed of light

  • you see the ball taking speed from your point of view in 3d... it's going at constant speed form the 2d point of view... (or something similar...)

  • @shagster1970 Analogy alert! If the fist is removed instantaneously, the couch reforms at its own 'slow' rate. There will be a time when the fist has gone but a dip remains, still pulling the ball in.

  • thats actually what would happen

    if the sun dissapears suddenly (just imagine it could happen)

    then we would still spin around in orbit for 8 minutes, and still see the sun for 8 minutes

    since everything we see is "delayed" cus of the light speed limit

    and gravity also works at light speed ....

  • Comment removed

  • @CenaxKikia yes it does ....thats the basis of einstein's theory ...

    what u just said is newtonian physics ...but u cant apply that to gravity.

    gravity works at light speed ...and this is already prooven by countless experiments .

  • @CenaxKikia #

    sidewaysfcs0718 is right gravity works at light speed.

  • @CenaxKikia That's not the case. Gravity has the speed limit of light.

  • I know this ;p

  • actually the couch doesnt warp instantly ...the couch warps at a finite speed ..

    in slow motion u would see the fabric shuddering like a "wave" ....like when u throw a ball against a glass window , in slow motion the window "warps" like a wave ..

    thats how space works ...but faster ..at the speed of light , gravitational waves move at "c"

  • 9.81 Newton.

  • Depending if you're at the equator or at the poles. The earth is not a perfect sphere and bulges at the equator.

  • I disagree. The possibility of Life, as I understand it is an emergent quality of systems arising from an energy rich environment.

    Yes, we need all of our environmental variables just right to support OUR bodies, but a completely alien set of variables can still support other forms of life.

    It's very sci-fi, but I don't see any reason life cannot emerge on the surface of a sun or in the plume of a supernova.

    It's just a matter of big enough numbers of similar units.

  • Is that ball a Pulsar, it's pulsing on and off LOL, I am just being silly :)

  • Where can I get a flashing institute of physics ball?

  • what am I going to do , Ive almost watched all the sixtysymbols videos !

  • At 4:32 you say "the average density of mars and earth are about the same." In fact mars is 28.6% less dense to be precise. That's not "about the same."

    Other than that ...I liked your video.

  • @MegaSkills9 For the purpose of that demonstration, that's obviously accurate enough.

  • how do we actually know the mass of the object that is causing the lensing? there's so much stuff in space it all would have an effect on light, can we really find just one source for the light?

  • how can you tell how far it has been rotated, by how much light is polorized in particular directions?

  • @masluxx

    Are you referring to something in the video?

  • @dudejohnny did you watch the video? The bit at the end talking about lensing? the mass of the star doing the lensing would dictate how far the light was bent. The mass of it has to be assumed, how ever gravity would shift the polorazation properties of the light and that you can measure dirrectly.

  • @masluxx

    I don't think it would change the polarization of light, but then again I wouldn't know. It doesn't seem intuitive to me

  • You guys should sell the Bill Nye cards I would so buy one.

  • Please rename this video to "how to fist a couch".

  • sooo is it an optical illusion for the person on earth looking at the light from the star thats being deflected by the planet, and if so how do u know its an optical illusion is that because of Einstiens equations?

  • @dmanz007 You can normally tell it's lensing if you see two identical stars in the sky. Otherwise, you can sometimes tell if the planet causing the lensing moves, it will change how the light is bent and hence how we see it; a bit of detective work can then tell if it really is being lensed. And I'm not really sure you could call it an illusion, but I guess thats just semantics.
