Flat earth vs round earth
by Jrjw inmy brother has been talking about the earth being flat and some big conspiracy going on to make people beieve otherwise.
what are people's thoughts on this?.

"on a serious note, does anyone have a reasonable explanation as to how the atmosphere doesnt simply get siphoned off into the vacuum of space?...
...gravity doesnt seem to be a good explanation. i know theres a pressure gradient. near the surface, an air pressure gradient results in a wind blowing in the direction of lowest pressure as the high tries to equalize with the low. why not the same from the surface to space" - Robo
Gravity does help insofar that it sets a speed limit that an element has to achieve in order to escape the gravitational pull.. For an element to escape the gravitational pull of the Earth its speed has to exceed @11km per second. The Sun can excite elements in the high atmosphere to an extent that they go fast enough to escape. We would lose a lot more if the Earth wasn't protected by the magnetic field because that handily deflects a lot of energy that would otherwise be absorbed by these elements.
Density also plays a part. Denser elements/compounds are closer to the surface and lighter ones further up in the atmosphere (think stones and corks in a bowl of water). There are also a lot more elements/compounds at sea level than, say, at the edge of the atmosphere. That also helps slow down the speed of these components of our atmosphere by giving them something to 'bump' into that slows their relative speeds. Higher up, with less things to bump into, allows far greater speeds and we do see losses.*
The Earth does lose a lot of mass to this bleeding into space. It loses about 140000 kg per day. However a lot of these are replaced by the various geological processes going on in the Crust and suchlike.
It is interesting how the atmosphere gets all mixed up by the various forces in action but that in itself is another topic and requires a knowledge of the Coriolis Effect which in itself requires an acceptance of a globe shaped Earth.
*I understand what you meant about the pressure gradients and that the greater pressure should move to the lower pressure to stabilise the system however the force of gravity overcomes this and, of course, it is gravity in the first place that is causing the greater pressure to be at sea level.

Did man really go to the moon?
by atomant inl have researched this subject and come to the conclusion that no we didn't.what do others think?.

"refusing to honestly examine evidence" - Robo
The evidence that we went to the Moon is overwhelming.
It is not 'us' that are refusing to honestly examine the evidence. YouTube videos where the uninformed make wild accusations that are easily refuted with even a modicum of knowledge is not evidence that is worthy of a lengthy refutation. It would, however, be a fun distraction if it weren't for the fact that some people actually take this very seriously!

I think some people confuse "do not know how they did it" referring to how the logistics were organised to achieve something with "do not know how they did it" referring to some elusive lost knowledge meaning we could not replicate their achievements.
Archaeologists must love these type of people as much as biologists love creationists...

Is YouTube part of this conspiracy now too?
As are all the other countries in the world.
If Occam's razor were a real thing I think it would get extremely blunt on these Moon Hoax/flat Earth type arguments...

Spacy question - ISS and gyros - what u think?
by MrRoboto inlots of spacy questions lately so i'll add mine here.
theres a video of one of the guys on the international space station doing some experiments with a few portable cd players, using them as gyroscopes when turned on.
it was interesting to see.

"l believe these objects are a lot closer than we are being told" - Atomant
Why?
Why are we being lied to?
What is the point?
There are thousands of videos on YouTube of people debunking evolution. Their arguments are all repeats of one another and all fail even a cursory examination with reality. There are thousands of cartoons on YouTube; they aren't real either.

Comments are disabled for that YT video above. It seems the Sun doesn't shine on that particular page either...

"does this mean that the ISS doesnt orbit the earth but rather the earth is spinning beneath it?" - R
No, the ISS has to orbit the Earth to counteract the Earth's gravity.
"sounds fair but the iss is supposed to be moving much faster than earth. or does it move just about 700mph in opposition to the earths rotation, causing a relative speed of about 1700 mph?" - R
Gravity is trying to pull the ISS to the surface of Earth. To counteract that effect without the need for continuously firing rocket engines the ISS has to travel perpendicular to the surface of Earth fast enough to maintain its height. So for every 1 metre that the ISS falls to ground it needs to have moved along far enough so that it is still the same height above the ground (the Earth's surface will fall away as the Earth is a globe).
"in that case, i would think the hypothetical gyro-box would wind up stuck to the walls and move around a bit as it resists the change in inertia/direction." - R
If you held that same gyro box on Earth about head height and then dropped it, what would happen? It would remain orientated in the same direction but it would drop to the ground, because of gravity. It would remain orientated all the way to the ground whereupon a collision would occur and those forces would overcome the power of the gyroscopes and it's orientation would alter.
In space, in the ISS, the box would fall like it does down here but there would never be a collision with the ground because of the lateral movement of the ISS (and the box inside, along with the gyroscopes). It just keeps on falling...

"The question is this: given the high speed and curved path of the ISS, what should we expect to see happen with an object that has active gyros in all 3 dimensions if we were to observe for 1 minute or more?" - Robo
The ISS is falling around the Earth. The gyros would also be falling therefore they should maintain their position inside the ISS... However, with 3 gyros active inside an imaginary box the box should orbit its axis once for every complete circuit of the Earth that the ISS completes because the gyros would keep their axle perpendicular to their spin... In other words, on one side of the Earth the top of the box would be pointing to the ceiling of the ISS then on the other side the top of the box would be facing the floor...
I believe that is correct based on my knowledge of how these things work... I may be wrong!

Also, it would be day at the same time all over the flat face of the Earth and there would be no opposing seasons either side of the equator.
You really do have to know literally nothing to believe the Earth is flat...
