Flat Earthers

[bigmarlon]

There were some strong articles that said that soy lowered testosterone levels in men and for a while I did avoid eating soy. I don't think there's conclusive evidence for either argument, so I avoid it as much as possible still just in case.

You're now officially "far-right". Enjoy.

There are people who genuinely believe that Soy milk makes you gay thanks to 4chan.

Funnily enough, cows milk has shit loads of mammalian estrogen in it which actually increase human estrogen levels. So if any milk was going to give you tits or ‘turn you gay’ because of estrogen, it would be cows milk.

The phytoestrogens in soy are actually though to have a positive affect and could help reduce the chances of prostate cancer developing.

Still waiting for someone who can explain the tides, flat earth or globe.

Still waiting for someone who can explain the tides, flat earth or globe.

The earth is under the gravitational influence of both the moon and the sun. The rocky parts of the earth are solid and are not affected. However as water can be moved freely, the sun and moon can have an influence. Both will only move water by a small amount, which is why you can not really see this in a large lake or puddle. However in a large connected body of water, i.e. our oceans, the cumulative effect is quite pronounced.

Rather than being like the view you have as a kid where when the tide goes out it is going in on the other side of the sea, oceans around the world are sqeezed and pulled together. For example, the next high tide in Sunderland is 3:13am, with Esjberg in Denmark (roughly due East) reporting 1 minute later. Cape Town has a high tide at 3:52am despite being in the southern hemisphere. However on the opposite side of the world, Tokyo has a low tide at 3:36am. Sydney is further west and has its low tide a few hours different to Japan.

Around the same time, the moon will be high in the sky above the UK with the sun 3 hours from rising. Our side of the earth is pointing at the moon and the sun is starting to have an effect on our side. This gravitational pull is pulling the water more water towards our side than the opposite side. The closeness of the sun and the moon affects how high the tides are, which is why some are higher than others. Also because the planet is on a tilt, some points of the year, we are that bit closer to the sun it has a higher influence.

It is a bit like scattering iron filings on a table and waving a magnet high above them. There might not be the pull to suck them right off the table but you can see a wave as they stand on end.

Tides could work on a flat earth. I don’t know their explanation, but if you picture the world like a clock face and you have two invisible hands under the surface opposite each other, one pushes water up while the other sucks it down. The peak of the tide would move round in a wave following the pointer. That sort of works, but has a couple flaws. They don’t believe in magic invisible forces that has an attractive pull on objects like gravity and magnetism, and secondly they believe that water always lies perfectly flat and that is why the earth is flat, so can not add a theory showing it does not. It also can not explain higher spring tides.

It is a shame, because if you made a flat model of the earth, then made it 3d by adding terrain and moving tides, it would be quite pleasing and clock like to watch.

Well I knew all that man, I was told that at school, the same has you were, but it doesn't explain how the gravitational pull of the moon can pull billions , no, probably trillions of tons of water off he face of the earth but doesn't effect anything else and I'm not sure about the great lakes, but it doesn't seem to effect them either, so it makes no sense, it just doesn't add up, by the way, where did you copy and paste that from?

I said in my post why it does not effect great lakes. It is not pulling water off the face of the earth. It is making a comparatively small swelling in the oceans.

I didn't copy and paste, I wrote it just for you.

Lakes have tides, it's just they're usually so small that you don't notice them. In the case of the Great Lakes it's a couple of inches:

The pull of the moon does effect the solid bits of the Earth. To see the tidal effects on a solid body, just look to Europa:

A small swelling? how if it's not pulling water of the surface how can it swell?

That may well be the case, but how does it not effect anything else?

It does. You just don't notice it, just like you don't notice - for example - the ripples gravitational waves cause.

It is not sucking it off the surface just pulling it a little bit.

What other things would you expect it to effect?

Pulling it a little, pulling it toward itself? what other things, well everything, surely it's all effected by the same gravity, so if the moon can pull water a little then it can pull thing that are lighter than water. no?

But also see what I said about not being strong enough to pull right off the surface, like iron filings getting a little excited in the presence of a magnet. Say you have a A4 sheet of paper, it is not going to levitate at high tide. If you could wrap it around the world you would see it rise slightly in the middle at the same time as high tide.

I'm not sure how else to explain it, sorry.

 

[Teed]

It does.

That's saying that part of it is to do with the rotation of the earth too, now that makes even less sense, on top of that, that's the same stuff I've read for years, I've read all this stuff and it still doesn't add up, Wiki is just spouting all the shite that NASA pump out and I would trust NASA with the remote for the telly, never mind the truth.

Slight tangent but I have a question for the clever members. If birds etc navigate using the magnetic poles , how is it they can return to the exact same places when they migrate back. ? Surely the fact the poles aren't in a fixed position is going to mess with their navigation?!? I'm pretty sure there must be a reasonable answer to this but it has me puzzled.

The magnetic poles are not fixed but move quite slowly, in the lifetime of a bird the change will not be that dramatic. I think birds use visual cues too, which helps keep them on course. There have also been experiments in planetariums where they rotated the stars and the birds started roosting on the other side.

However, they have predicted that the poled could flip soon, which they have done a number of times in earth’s history. That will be quite sudden so it will be interesting to see the effects on birds. There are a couple of articles worth a look at:

Does the moons gravity have any effect on the bird if it's flying over an high tide area, would it make it harder for the bird to land?

No idea, likely negligible effect. People can’t noticeably jump higher during a high tide.

See, that's where all that gravity falls to bit's for me, something as light as a bird, it should be a noticeable effect, you said yourself the moon pulls the water slightly, now even if it only pulled it an half an inch away from the surface, over a third of the globe, that would be an unbelievable weight to shift, so a bird should, in reality, struggle against the gravitational pull.
