"Where's The Edge?"

[togor]

If the earth were flat, you should be able to see right to the edge - on a very clear day. You go to sea at all, you can see the horizon from main deck. Go up to O2/climb to the maintop and you can see a horizon that is farther away. That means your ship is on a curved surface. If you can sail around it one direction and return to home port, it is a surface with a closed curve.

It's a myth that sailors were terrified they might fall off the edge. Press-ganged landsmen, maybe. There was plenty else to fear once you sailed past the Pillars of Hercules.

And if there was no edge (if some somehow think that), then either an infinite sheet or closed spheroid. Geometry gives us no other options. An endless sheet would solve a lot of social problems. But COMSATs and NAVSATs would have problems.

maybe we should create a ring world?

Flat earth, Russia collusion, bribery, man man induced climate change..........all held back progress and all were/will be proven false.

Climate change and round earth deniers both are choosing to go with their 5 senses over the great mass of scientific data on what is admittedly a pretty big subject--the whole planet. The earth seems as flat to them as it did 20 years ago, at least around here, and more or less the same temperature.

Now is there such a thing as a flat-earther who also believes in climate change? Gotta meet that guy!

That guy is you. You are totally convinced that climate warming is happening because of hair spray and cows farting. That is as stupid as the flat earth jerks that are just jerking chains... they seriously do not believe the earth is flat. Just as you seriously don't believe that global warming is man made. It is just a "up yours," farce. The earth warms and cools over thousands of years not from year to year, or decade to decade, or century to century.

It is another opportunity for you to spew your hatred.

Red if satire it's pretty dry but sure, okay.

I believe that seven miles is the maximum distance an object can be seen at the water level. The distance increases in proportion to the height of both objects. It’s interesting to be driving along Interstate 90 in Erie County, PA on a clear day and look out across Lake Erie and be able to see Long Point, Ont and realize that it’s probably about 19 miles away. Of course, portions of I-90 are elevated a hundred or more feet above the water level.

I was standing on the beach at Dover (on I was told a rare bright sunny day) in Mar 2008 and could see Calais France,
