If the moon can pull the whole ocean, why don't we feel that gravitational effect on ourselves?

[@EugeneKhutoryansky]

Tidal forces are created due to the fact that the gravitational field from an object (such as the moon) is not uniform throughout space. This is noticable when the gravitational field acts on a very large volume, where the gravitational field is very different at different points in the volume. This is hard to notice when the just looking at how the gravitational field acts on small volume (such as a human being) because the gravitational field is not that much different throughout the body of the human (unless you are near a black hole).

[@triplezgames3882]

@@EugeneKhutoryansky Why does a non-uniform gravitational field have a stronger impact than a uniform one? Sorry for those stupid questions, but it still doesn't make sense to me...

[@EugeneKhutoryansky]

If you were inside a closed box falling in a uniform gravitational field, then you would feel weightless inside the box. You can't "feel" a uniform gravitational field.

[@triplezgames3882]

@@EugeneKhutoryansky Oh wow that's a great explanation... Thanks a lot! I'll think about it

[@MScienceCat2851]

​@@EugeneKhutoryanskywe cant feel it because imagine youre falling, the gravity pulls every particle at almost same rate, meaning you wont feel anything as anything is not applying pressure to you. Every particle of yours get accelerated at same time almost same rate ( the difference is small, but in big distances it decreases) . The moon doesnt pull the whole ocean, but since gravity is pushing the water towards it self, the moon wont pull it as it foesnt have stronger gravitational field, instead it, when moon passes, in horizontal direction it attracts particles of water, not in vertical relative to the planets gravity as it wont pull it, just make the weight of it lighter. But even if moon was above earth, whihc I suppose, it would pull the ocean up again, not because gravity is stronger, its because the pressure of the ocean and that part at top begin lighter.

In the water cube case, if we make water molecules smaller and add more of them to create grid lines, the motion, in which water is attracted to the planet, is indeed how space-time is distorted.

The moon actually drags the water around the surface of earth. This actually transfers some of the momentum from the moon to the earth, slowing the moon down.

[@naveen.v4734]

Hello excellent video ! I just want to know more about this , I was always confused by how gravitational attraction creates tides ! but It was clear that the force of attraction and the movement of the moon causes these waves , but how do we explain that during the newmoon/full moon phase we say its tides get much bigger and also is the direction of waves is dependent on direction of rotation of moon ? Thank you for your time !

[@zombieregime]

If I understand the question correctly, the reason why the tides seem higher or lower during new and full moon phases is due to the sun also having an effect. During a new moon, the moon and sun are on the same side of earth, ergo there is more mass tugging in that direction. Remember, there is no hierarchy to gravity, if there is mass there is gravity. Two particles on either side of an otherwise empty universe will be drawn towards each other simply by the distortion their tiny masses have on space, eventually they WILL meet. Of course, they need to be closer than the expansion of the universe moves them apart, and I suppose that means there is a butter zone where the two forces are equal and they would remain a given distance apart.....but that is very high level physics, so not entirely important for the general idea of the topic at hand. And Im not sure such a steady state of equilibrium would be stable for very long. So, basically, more mass in a given direction, higher tide (by up to 20% over average tidal levels according to a few sites I skimmed over). As far as wave direction and moon rotation..... Im not quite sure what effect you're referring to (possibly something lost in translation? Hey, second languages can be tricky. I only speak one, and not very well! LoL), but the moon is 'tidally locked' to the earth. Not really tide as in oceanic tides, more when the earth and moon were more molten any rotational energy the moon had would have been bled off as it solidified (the moon tugs on our water, but the earth also tugs on the moon. When it was a lava ball, it would have had some kind of bulge in our direction). As such we only ever see one side, the so called 'light side' of the moon. The 'dark side' gets its name mostly from the fact that until we tossed some probes at it (and later, a few humans) we didnt know what it looked like. We knew it was there, so we had some rather firm indication it existed but otherwise we had no data on it. In other words, we were 'in the dark' regarding that side of the moon, thus 'the dark side'. Also we only really see the 'light side' when its reflecting light from the sun, otherwise the light scattered by the atmosphere during the day washes it out (except when it gets in the way, of course! By the way, there will be an eclipse in north america on the 14th, so in about a week (from time of writing)! The moon gets even illumination from the sun on its trip around the earth, its solar days are 28 earth days long! So, if you lived on the moon youd have 2 weeks of baking in the sun, then 2 weeks of freezing under the slow sweep of earth drifting across a field of stars (which we cant usually see in images due to how bright earth is, the differences in exposures to capture the earth vs stars means you have to choose one or the other. Just like images of the moon from earth, if you want to see the craters, or not blow out the frame of a wide shot, you're not going to see much if any stars in the black bits....at least not on a single exposure. Compositing frames at different exposures is the only way to get both in one image). (Looping back around after that tangent....) Waves are generated locally by winds interacting with the water surface and turbulent flows inside it. So other than the moon, and sun, influencing flow they otherwise dont have a significant effect on wave dynamics. Other than the direction of that influenced flow of course. And hey, good on you asking questions! The only stupid question is the one left unasked. Any person willing to rail against an honestly asked question isnt worth taking advice from in the first place. Also, anyone who resorts to insults and aggressive rhetoric, especially right off the bat, probably doesnt know their ass from a hole in the ground. There are nearly infinite wonders out there in this beautifully simple complex natural universe, undeservingly muddied by myths and monsters. We have been provided (however one chooses to believe that was achieved is up to them, faith and science are entirely separate incompatible irreconcilable concepts, no need to try forcing them together as so many attempt to do) with lightyears upon lightyears of amazing interactions between unfathomably large to unimaginably small objects, structures, and forces. In all that wonder, how did we ever manage to create boredom? Simply amazing.... Anyhoo, be careful how much you open your mind because your brain can fall out, and someone will come along as stick their garbage in the empty space, but otherwise keep looking up and stay curious! There is still plenty to see!!!

Thank you and I am grateful for your answer and I thank you to take time in your day to answer such an obscure question lol !

[@zombieregime]

@@naveen.v4734 The moon, and indeed any mass, will affect any other mass. While this does also mean the air mass of the atmosphere does also experience a bulge (and even the earth itself, thats part of the reason for the far side high tide. However that is getting into wildly complex geophysics and fluid dynamics that I only loosely understand as a concept and couldn't hope to explain in a meaningful way beyond 'lumpy thing make water go craycray(crazy)'), effects localized on the planet like thermally driven convection currents (technically those are due to the sun warming the air and surface but its essentially a local effect), high and low pressure zones due to how those currents blow around features on the planet surface (mountains make air go craycray), humidity of those air masses (which itself has to do with temperature since warm air holds more water vapor, when you see time lapse videos of clouds exploding into being thats because a hot wet air mass is slamming into a cold air mass, cooling down, and the water condenses out. Get enough of it in one spot, you get a down pour. Or worse, if a air mass punches through another, it can set up a swirl that can evolve into a tornado (along with other closer to the ground effects and such)). Meteorology (weather science) is crazy complex to say the least. But as far as the wind and the waves, that is effectively more the natural 'sloshing' of planet scale water coverage, the tides while driven by the moon (and lesser extent the sun, and a much lesser extent other massive bodies like Jupiter, and a teensy tiny non-zero amount the super massive black hole at the center of our galaxy (Sagittarius A* (pronounced A-star))) the waves are more of a dynamic between wind over the surface and the geometry of the shore line (as a surge rolls in and the depth gets shallower and shallower eventually the water mass gets too tall and breaks over. But even that is an entire field of study encompassing geology, oceanography, meteorology, fluid dynamics, and probably a hand full of others I'm forgetting....). I mean, the waves still roll in and curl even as the tide goes out. And yes, there is certainly some interconnectedness between all of these phenomena, there are mechanisms that are more heavily attributed to things happening on the small scale (the surface of the planet in a given area), even if ultimately they are driven by forces on a large scale (celestial bodies playing tug of war). Getting a handle on all the physics driving everything around us takes a little bit of letting go. Its sort of like as you get closer to the small scale effects and you get a higher resolution view the things above that become less rigidly defined, likewise if you zoom out at some point you loose sight of a single grain of sand and just accept that if the waves come its getting wet, further out and the oceans mass is the highest detail you can see and beach sand is a concept you can see anymore. You can see the beach, but not the sand gains. The tides and the moon become apparent as you zoom out further. Eventually even the ocean tides are too small to see and the gravitational dance of the earth and moon is the clear dominant view. Still further their dance around the sun, then the inner planets, outer planets, solar system, our local group of stars, our galaxy, galactic neighborhood, cluster, super cluster, galactic filaments, finally at the edge of all that we can see with a web of trillions upon trillions of galaxies before you, each with trillions upon trillions of stars, potentially at least a handful of wet rocks circling some of those stars, and some water sloshing around, some sort of surface gas blowing around, what meaning does the stretches of tiny stones etched away from the rocks where the three meet hold? Or the molecules they are made of.... Or the atoms those molecules are made of.... Or the quantum wibbles that something something quantum weirdness tada, atoms..... Sure, we could put numbers on it all.....but why? What does it matter? If you want to count atoms, we use moles. If you want to could a lot of moles we use grams, kilos, tonnes. If you want to count stuff in stars we literally use our own sun as a unit of measurement, the solar mass. That being said, if you have a question that can be tested, rest assured we most likely have a method for testing those effects and forces down to a level and is unreasonably precise. But you want to know a secret about a lot of this stuff....unless were writing a white paper to advance a particular field of scientific research....a lot of numbers are either quoted directly from said research papers (where someone (or a team) spent years if not decades measuring, remeasuring, looking for things wrong in their hypothesis or testing method, before finally being happy enough with the repeatability of the experiment to publish, for other scientists to attempt to replicate potentially revealing a flaw, and if not the findings are accepted as factual but only in the case of that testing method. What Im saying is serious scientific research is serious, theory means something entirely different in science than in the rest of the worlds vocabulary) or honestly its ball parked ... It doesnt matter how far the moon is to the fraction of a millimeter unless youre experiment calls for it (and we have methods of measuring that with lasers thanks to retroreflectors left by apollo missions....and even if people on the moon is disputed (its not, even the russians who had the most yo gain from exposing it being faked believe we made it. Its fact.) we at least have landed robots on that rock, and that a lone is quite a feat) the 238,900 mile distance is mind blowing enough for trivia purposes, and really...for throwing tin cans of humans at it too for the most part... I kind of got lost in a point there that has since escaped me. I think what I was going for was dont fret over knowing what is the direct causal effect of what, or how much of this affects that. Just absorb it all. Take it all in. You'll go down roads that are plenty logical at the time then suddenly that "AHH HAH!" moment hits and you feel the burning need to "well, actually..." those currently on the road you were just on. Its all a learning experience. Muse on it, ponder upon it, but also be comfortable accepting the unfathomably complexity inherent in systems that exist from all we can see all the way down to quantum wibbles. Its all tied together on some level, and some levels are more significant than others depending on how close you view them. Knowledge is your vaccine from ignorance. Just keep learning and reasoning, and youll pick up on the tricks people play on each other including we on ourselves. People say Im smart, I say I just know ehat the big words mean. I left school at 14 and fell bassackwards into physics and chemistry trying to figure out what the hell an electron was doing in a transistor. So when I say anyone can learn this stuff, I mean ANY ONE CAN LEARN THIS STUFF! I did. You're well on your way asking questions. Its up to us to share what we understand, as we understand it, to anyone curious. I am not expert, and I want to be clear on that, as we all should be. But that doesn't mean deeper understandings need to be the realm of academics. The average human is smarter than society tends to let them think. We all can get there, all it takes is being kind and never cruel, to share our experiences and knowledge, and being open to the new without the expense of the comfortable. And if that part up there about things loosing meaning was a bit depressing remember, our meaning in life can only determined once its over. So make it a good one😎👍 Ps hopefully that all makes sense, because its such a wallOtext, mostly fueled by not being entirely sober, ergo I probably wont edit it...much....but if something doesn't make sense, ask away, im usually around, eventually 😅

[@-_Nuke_-]

Everyone forgets how gravity really works. For example: Lets take the Flat Earthers... Their naive model has a flat disc that is accelerated upwards to hit an object. Because they think that that's how gravity behaves. But their model can't explain tidal forces. The gravitational field ISNT uniform. And that is the reason why it can't be explained by the flat Earth model but also can't be explained by special relativity either... We need to enter General Relativity and curved spacetime to explain gravity and most importantly explain all those tidal forces.

[@carultch]

Newtonian gravity explains the tides perfectly well. It is overkill to use general relativity, at least for the tides on Earth. If you were working with tidal forces due to a black hole or neutron star, then you might need the precision of general relativity to explain tidal forces in that situation.

[@carultch]

The flat disc accelerating model, can easily be debunked by the fact that gravity varies with geographical location as well, which is about +/- 0.3% from the global average. Their model would require uniform apparent gravity everywhere on the planet.

[@adeboyegrillo3408]
