Why not to share some interesting facts here? Here you go;

Iron mines in Michigan's Upper Peninsula have many of their tunnels only accessible when they are continuously pumped out. Otherwise, most of the tunnels are completely flooded going down hundreds of feet. When ore goes to a price that would make a particular deposit profitable to mine again, the mine could be pumped out. At least one such mine is maintained above grade with a mining railroad running into the tunnels above grade, for tourists, but all the flooded shafts fenced off from tourists. All of this is old hat to mining families, but odd to others.

If the Earth was perfectly spherical and smooth, and a string was wrapped around the equator,

you would need to splice-in only 3.141 feet of extra string to make it slack enough to suspend

it 6 inches above the entire surface. The same amount would apply equally to a basketball.

Does this chart mean that folks on the equator would be hurled into space at 1000+ mph, and those at the poles would hardly move, if the earth's rotation were stopped instantly? Inquiring minds....

The Earth itself is also moving at around 67,000MPH relative to the Sun, but the Sun is orbiting the center of the Galaxy, and theoretically the Milky Way is spiralling off in on direction or another, but as far as I know there's no way to tell which direction the galaxy is moving.

I don't think we have a distinct orientation for the universe yet (where did everything start from and where is it going?).
I would love to see people at least attempt to send a probe to Alpha Centauri someday.

The Great Pyramid at Giza was not built by slaves. The workers were extremely well fed, had family housing, great healthcare and were specialists in their field.

That's theoretically correct, if the earth's gravity have been stopped for a second, that would have happened.

Read this one, an amazing article indeed: http://www.bbc.com/earth/story/20141106-why-does-anything-exist-at-all
