Tides.
« on: May 17, 2017, 04:09:20 AM »
According to the Wiki, tides in the FE theory are due to gravity from the sun and moon.

How does this explain that there are TWO lunar tides in each 24 hour period?  In the RE model, the Earth/Moon system orbit around a point a little off-center from the center of the (round) Earth. The tide that happens when the moon is overhead is just gravity, same in FE and RE physics.  But the second daily tide (which happens in RE theory because centrifugal force produces that second tide due to the off-center rotation of the Earth.

What is the FE explanation for that second daily tide?

Relax, half of those views were probably you re-checking the thread. People generally only respond to posts they're interested in, and "hi I didn't do my research plz do it for me" falls quite low on that list.

According to the Wiki, tides in the FE theory are due to gravity from the sun and moon.

How does this explain that there are TWO lunar tides in each 24 hour period?  In the RE model, the Earth/Moon system orbit around a point a little off-center from the center of the (round) Earth.

To begin with, you are incorrect about how tides work in the RE model. A "tide" isn't a singular event that's somehow isolated from the rest of the day. As the Moon circles around the Round Earth, it pulls water in its direction. This is an ongoing process.

Here, for example, is the tide chart for Bondi Beach in Sydney: http://tides.willyweather.com.au/nsw/sydney/bondi-beach.html



You may notice the pattern's striking similarity to a sine wave, which should be obvious given the elliptical pattern of the Moon's movement around the hypothetical round Earth, and the round Earth's rotation around its own axis.



Now that you have a fundamental understanding of RE tides, let's return to your question: How does the Flat Earth model explain tides?
The answer, perhaps unsurprisingly, is that it's not much different from RE. The Moon travels around the Earth in an elliptical pattern and pulls the water along with it. The direction and strength of that pull depends on where the Moon is on its path.

No - the moon passes overhead ONCE per day - producing a peak in that sine wave as it goes overhead (plus or minus a bit to allow for the time for the water to flow to where ever it needs to be).  BUT...and this is the critical thing...about 12 hours later - when (in RE terms) the moon is on the opposite side of the Earth - there is a SECOND high tide.

So your sine wave (which isn't a bad approximation of what we see) has TWO peaks and TWO troughs in every 24 hour cycle.

Actually, because (in RE terms) the moon moves around the Earth once every lunar month - AND the Earth is rotating - the cycle isn't exactly 24 hours...but roughly speaking...there are TWO high tides and TWO low tides every day.

If you check here:

http://www.myforecast.com/bin/tide.m?city=30578&metric=false&tideLocationID=T8285

You'll see that on Sunday, in Houston Texas, there will be high tides at 6:15 AM and 6:23 PM and low tides at 12:48 PM and 11:50 AM.

In RE, the first high tide happens when the moon is at it's zenith (plus or minus a bit) - and the second when the moon is on the opposite side of the Earth.  That second tide happens because the Earth and Moon both rotate about a common center-of-gravity that's not at the center of the earth - so there is a centrifugal force acting on the side of the planet that's furthest from the moon that creates that second tide each day.

I understand your explanation of the FE moon having gravity and causing tides...makes perfect sense (well, kinda)...but you CANNOT explain the second tide in the same way.   If the Moon's gravity was the only cause then there would be just one high tide and just one low tide each day...because (just as in RE) your moon will only be overhead ONCE in Houston Texas this Sunday.

There are CLEARLY two tides every day.   This is a fact that absolutely anyone can easily check for themselves - and for which tide charts are easily available if you don't want to move from your chair to verify it.

Your moon can't produce a second tide...it's too far away - when the second tide comes in in Houston, your moon is over the other side of the world!

So...where is the second tide coming from?

If you can't explain this - you don't have any clue as to how tides are formed because FE theory predicts only one tide per day - so the idea that the moon's gravity is responsible simply doesn't work.

Come what may - your Wiki is incorrect.

So - at time of writing, 85 people have viewed this thread - and the only response so far can only explain ONE tide per day and not TWO.

Have FE'ers given up on this?
