I watched the start of this crap, just to see if this guy actually could explain, in a clear way, why there is a high tide on the opposite side of the Earth away from the Moon, at the same time there is a high tide on the side facing the Moon. No, he didn't do it. He fudged it, just like every grade school teacher you've ever listened to "explain" the tides. They never actually explain the tides, because they don't have any idea how the tides work.
The high tide nearest the Moon is simple enough -- they tell you the Moon pulls the water toward it. OK, fair enough. There's about as much basis to this explanation as there is to the notion of "suction" but at least it seems to make sense. But when it comes to the simultaneous high tide on the opposite side of the Earth, they never explain it. It's counter intuitive that the tide should be high on the side of the planet facing away from the Moon.
Frankly, I have NEVER, in my entire life, heard anyone else give a clear, simple and accurate explanation as to why the high tide forms on the side of the Earth facing away from the Moon. I had to figure it out for myself, which I did when I was around 18 years old. All the explanations are total bullshit. You'll notice, if you watch any of them, that the teacher tends to rush through the explanation. Of course -- because the teacher is talking out his or her ass.
yeah they lost me there for sure
tides are super interesting, especially "internal" tides out on the moons of Jupiter.
Same here; still looking for an explanation. Also, I remember seeing a map showing the daily number of tides and it's not the same everywhere; some place only have one tide each day, others have 2 but other places have 4. It can also be different along the same coast, so I have no idea how the tides work. I cannot find that map so if anybody know what I'm talking about, please share; or if I remembered wrong, please correct me.

How does it not make sense to you? Think of the Earth when that happens. There's a ring around Earth perpendicular to the Moon - Earth axis (imagine the - is a + and the ring around Earth lines up with the vertical line of the plus character). That much water displaced from pulling the water to the side closes with the moon will be insanely enormous, even though it's inches, feet, centimeters whatever, the mass is great. When the ... this is going to be very hard to explain... water pulled by the gravity of the pull on the close half is matched by the force of the water it pulls. The now lower gravity perpendicalr ringe will cause a similar displacement on the opposite half of the Earth that is away from the moon.
' | ' | F-Earth-N ------------------------ Moon ' | ' |
Ignore the ' necessary to preserve placement. So the perpendicular ring I speak of runs through the word "Earth" vertically. The near side of Earth is represented by N. The far side of Earth is represented by F.
So when the Moon pulls water due to it's gravity to the N side it will cause a displacement on the water with subsequently lower pull the farther from the vertex of the N side - the perpendicular ring. With this water "removed" from the ring and now on N a point in which the amount of force to pull more water equals exactly that of the pull back (equal and opposite, it's a law). What this does then is significantly lowers the gravity around the center of the Earth alinged with that ring. This then means the F half of Earth has a higher gravity than the middle section. This will also cause a high tide on the F half, though not as great.
TLDR / don't understand; It comes down to Newton's 3rd law.
