Neil deGrasse Tyson Explains the Tides

[@vpheonix]

No disrespect to NDT but I prefer this video on the tides. kzbin.info/www/bejne/pqimmZ5qiJ5sn5Y

[@R3_dacted0]

Unfortunately those animations didn't properly visualize what he was explaining. Water doesn't "rise" off the surface of the planet directly under the sun/moon. It flows towards the sun/moon from the surface that is tangential to the force of external gravity. So if you imagine the Earth as a large circle and the moon as a smaller circle to the right of it, the water isn't "rising" from the side of the Earth closest to the moon. What is happening is that the water from the top and bottom of the Earth circle is flowing in the direction of the moon. And as the water flows that way, it bunches up with more water and more water and more water until the large bulge is formed.

Neil deGrasse Tyson is a one of a kind. He has a brilliant understanding of the world, coupled with an extraordinary ability to explain complex concepts to the layperson.

[@ScienceBusted]

Physicists are pig-headed Tides are an artifact of coastlines moving in stable seawater, caused by thermal expansion of the crust caused by moving sunlight. Lunar gravity has nothing to do with anything on Earth. Scientists are dumber than pigs for believing that tides, which move at different speeds and in different directions one to four times a day in different locations and at heights ranging from 3 feet to 50 feet, are caused by the moon's gravity.

[@n29nick]

Just a theory. Back before we had artificial lighting illuminating our towns, full moons allowed enough illumination for people to go out at night. Meaning more mischievous or unsettling things went on, on nights with a full moon, thus causing the correlation between lunatics and full moons.

[@mukrizhsmukmuk9252]

Ooo... That actually kinda make sense

[@kiirthanjeevan4790]

that makes a lot of sense. because especially back then when people didn't have any efficient means to record incidental evidence, all they do is claim based on what is recorded in their memories. and that defeats the purpose more as memories come with emotional imprints. we only remember or "SEE" what we want to, especially when we are emotionally stressed (any kind of emotion). they get to be up longer in the darker hours of the night and perceive events with psychologically or mentally stained perspective. thus, creating all these stories of dramatic lunacy!! lol; You Sir, should be knighted as Sir Sensalot! xD its a sound and logic inference that we have here because of your intellectual spur. very much making a lot of sense. nice bro

Great stuff. As a sailing instructor I also add two other factors that affect tides. One is whether or not the moon in apogee or perigee. The other is whether the moon is in the southern or northern hemisphere. One other question: why are tidal ranges n=more pronounced in northern latitudes?

[@suedenim9208]

Latitude has absolutely nothing to do with tidal range. If you've sailed in the Caribbean or similar places you're surely aware that the tidal ranges are mostly modest, but that's because the landforms tend to be simple and there are few long, large, narrow bays and the islands mostly do rotate into a simple bulge. If you're like most people you're thinking of the huge tidal range in the Bay of Fundy, but the highest tides are at the most inland point, which is east and south of places with lower tides. If you head north (and east) to St John's Newfounland the maximum tidal range is about 4.5'.

[@jacdale]

@@suedenim9208 In the higher latitudes of the northern hemisphere, the continents of North America, Europe, and Asia are pressed closer together. This “constriction” of the oceans creates the effect of a higher range of tides.

This might be my favorite informative video of all time

[@wavydaveyparker]

Yes mr Tyson, you make a very good point, and as I keep saying, the tides are a natural consequence of inertial motion in a non-uniform gravitational field. They are not solely due to the gravitational differential. In your scenario, with a constant gravitational field, without a gradient, then not only would the earth’s center of mass be “in orbit”, free of any force, moving on a geodesic path around the barycentre of the earth-moon system, but so would all the others parts as well. Therefore, the Earth would not experience any tidal force across its diameter. This is true for all celestial bodies. Inertia has an important part to play in the formation of tides, and it’s not solely due to the inverse square law of gravitational geometry…but, you try telling that to the masses! 👇Take care.

@atavistic_platypus Thanks, but I guess you gotta go with the flow, bro

[@ScienceBusted]

fact killed science Tides in the Bay of Fundy proves all scientists are delusional fact deniers. If tides are caused by moon’s gravity, how can high tide in the eastern Bay of Fundy 50 feet, but only 20 feet in the western Bay of Fundy? In fact, tides are an artifact of the up and down movement of coastlines in a stable ocean, caused by thermal expansion of the earth's crust due to moving sunlight.

[@teeanahera8949]

Across the Earth’s diameter? Don’t you mean circumference?

[@MrMarcusIndia]

While I understand how the bulge can be caused by water on the side of the Earth facing the moon, I've never understood why it also creates a bulge on the other side of the Earth as well. Unfortunately, other than saying that the moon's gravity stretches the water along that axis, this video did not explain it.

[@perseverancerover]

Hello Marcus, I really do feel your frustration, that far-side bump is a real bone of contention amongst scientists. And unfortunately, it isn’t helped by _you-tube,_ who willingly promote the wrong videos, which continue the spread of scientific misinformation and completely poison the waters of curiosity. All I can say to you is this…there are approximately two tides a day on planet earth! - some will say, its the water stretching…others will say, it’s the water being squeezed from the poles, in the form of an anti-gravity effect…and real physicists will tell you, it’s due to the centrifugal effect of the earth in motion around the barycentre. They are all in essence the correct answer, but require further clarification, regarding the finer details of hydrostatic pressure. The one thing we can both categorically say without any doubt whatsoever!! Is that… *“the daily tides are not caused by the earth moving in a straight-line, directly towards the moon, filling up bulges and leaving water behind and then somehow magically stopping”* - because, that is completely ridiculous and contravenes the First Law of Motion. I really hope that eases the frustration, but acknowledgment for my effort in typing would be greatly appreciated. Take care.

[@MrMarcusIndia]

@@perseverancerover Thanks for the explanation about the barycentre. That intuitively makes sense to me, though I wouldn't be capable of working through the maths. I'll check out a few more videos on the topic. Just find it frustrating that Neil deGrasse Tyson skipped over what are arguably the most important aspects like that, and expected us to simply accept "stretchy water". That said, it's fascinating to consider how the effect of the moon, the sun and Earth's own gravity and rotation all factor into what we experience at the beach each day.

[@perseverancerover]

@@MrMarcusIndia Thanks for replying, it’s not often I receive such thoughtful replies. You’re right! Neil deGrasse Tyson is a very frustrating scientist and has unfortunately become more concerned about his own popularity, instead of pursuing the aim to ‘popularise’ science - it happens a lot these days? Water is incapable of “stretching”? He really should leave ocean matters to the oceanographers, they’re the real experts when it comes to tidal complexity. I wouldn’t be too harsh on yourself though, I’m certain with the right guidance, you’d be more than capable of handling the maths behind the simple occurrence of two daily tides. It’s only when we factor in all the other peculiarities, like topography, that it gets really intricate and I don’t profess to know much about that! However, let me leave you with this little thought, as I just thought of it myself - _let me know what you think?_ - If we were able to cocoon ourselves in a protective shell, at the very centre of the earth! Then, we wouldn’t experience any ‘tidal force’ and wouldn’t even be able to demonstrate the existence of ‘gravity’ - because, we would be in free-fall around the barycentre and undergoing the effects of weightlessness! Now, that’s what astrophysicist Tyson should really be mumbling about in this video, instead of going off-script and talking about yoga, black-holes and spaghettification. Good luck and best wishes.

[@adarsh4764]

Because every spheroid object (for example - A rubber band) when stretched from one end it always becomes an ellipse. So it will alawys have a bulge on both sides compared to the previous shape even if you stretched it from one end.

[@riccitension]

@@adarsh4764 This is just a very polite suggestion. Only if you had something to hold the other end in place, and unfortunately there isn’t anything in the universe that can do that? Not even tyson. So, please put your spherical rubber bands down and start thinking critically about the problem. Cheers

[@MrCrazylegs18]

So a multi-moon planet with an ocean must have some interesting tides

[@chocomonstaar]

Or possibly... less interesting tides, as they could cancel eachother out the way the sun does with our own. Depends on if they are equally spaced and synchronised, or randomly spinning around, lining up sometimes and not others.

[@yutubvlogs8889]

I know moon causes tides.. but this clarification by neil blowed my mind.. I didnt knew that sun assists in high tides or rather the main cause of it. The full moon explaination was fascinating.

[@suedenim9208]

The sun isn't the main cause of tides. The gravitational pull of the sun is about 200 times as strong as the moon's but it's the difference in gravitational pull on opposite sides of the Earth that result in tides. Because the sun is almost 400 times farther away the relative difference in gravitational pull from the moon is almost 400 times the difference for the sun.

[@SurlyCurmudgen]

Is there a measurable difference in the height of the tide when all the planets are lined up on the other side of the sun from the Earth?

[@wavydaveyparker]

What a fascinating question. That is going to keep my brain whirring for ages, but are all the other planets ever lined up on the other side of the Sun from Earth? I doubt they orbit like that. They do occasionally all line up on the same side. Anyhow, we could possibly calculate the increased gravitational attraction of your scenario, and I suspect it might make a very slight difference to tide height. However, I don’t think it would be measurable over the normal height difference, because those planets would be an incredibly long way away. What do you think?

[@SurlyCurmudgen]

In addition to the question above how long until the next line up if there ever is a line up?@@wavydaveyparker

[@wavydaveyparker]

@@SurlyCurmudgen On May 19, 2161, all Solar System planets, including the Earth, will gather on one side of the Sun. The planetary alignment will be seen just before dawn.

Minor correction: Neap tides do not produce the lowest tides. They produce the least extreme tides. The lowest tides, like the highest tides, appear during syzygy.

[@wavydaveyparker]

Actually Sinatra, to be frank, you’re absolutely right, and to be entirely frank, it’s really a “major” correction, not a minor one that’s needed here, because it’s totally out of tune and completely flat. However, mr tyson has no regrets, he doesn’t care, and failed to mention the importance of inertia in his tidal explanation, deciding to leave his audience with the incorrect impression, that the sun pulls one side, and the moon pulls the other. Therefore, we have two high tides a day, and the Earth performing some peculiar stretching and yoga classes. _”There is no big explosion, no tempest in the tea. The world does not stop turning around, there’s no big syzygy.”_ Take care and goodbye my friend. 😂

[@Brandi.Nicole]

Cool. Did I get this right? And how would you write this in astronomical terms? Tidal Bulge is due to moon and sun influence. (Equation at different seasons?) Tidal bulge slows down the rotation of the earth. (Evidence through sea Mollusks, cycling) Earth is slowing and has been slowing down over time as evident from the cycling in sea mollusks. So…what is slowing us down? How does this influence earths axis? Can a slower speed change degree at axis? If so what happens? Will the moon influence us differently if our axis is different? 30, 45 or even 60 degrees!? Could it happen in a short time period - like the big whack? 😎 Will that influence speed of rotation considering tidal waves 🌊 are influenced? Why does speed of rotation matter the most? Can humans cause damage enough to harm our tilt or speed of rotation? What about space trash? Does it affect the gravitational pull? 😅 thanks - to anyone. New to this and have soo many questions!!

[@cybermonkeys]

That is a very interesting and questionable comment Brandi? :) And, you sort of answered your first question yourself really! Its the bulge that slows down the rotation - it requires a lot of energy to move all that water about and that energy must come from somewhere? And, it comes from the rotational energy of the spinning and motion of the Earth and Moon around their common centre of mass! That’s why it… ? …Maybe you’d like to laugh at my video first, before we continue with the answers there? Take care.
