once read a story of Cyrano de Bergerac (I think Trip to the Moon, but I remember it well), in which the protagonist falls asleep in a meadow and dew evaporates beneath his body, he lifts him up into the air. As the Earth turns and instead the man was floating in the air without spinning, when it does finally lands in a place other than the Earth's surface. This is about getting high-speed travel across the globe.
Cyrano seems to be very clear that the Earth rotates! I do not seem so evident. Much to my dismay, I have accepted that the Earth is round but I see her flat. But I do not see the Earth rotate or move.
I see are the Sun, stars and others what goes around us, and that throughout the day begins with a dot the horizon and eventually put on a different point. But I do not hear the motors that move the earth or feel accelerations by the fact that the Earth is rotating. So for me the Earth is still and are the other things that move.
addition, following the reasoning of Cyrano, if the Earth would spin and I jump out, separated from the surface, would also see as the ground moves and end up falling in another the planet.
I have calculated. Imagine that it took a second jump (since jumping until fall). Knowing the radius of the Earth I can see how many meters I shift to jump if I know that one day the Earth rotates one full revolution. Well, if you jump in Ecuador by land, in a second would be as I move about 460 meters (at a latitude as Barcelona displace me 350 meters). If they knew that the jumpers of the Olympics be thrown by the hair. How easy it would beat the current record (about 8-9 meters)!
So what happens? Does it show my calculation that the Earth does not rotate, because if the day would revolve hopping to visit the pyramids of Egypt and back for lunch? It goes. The earth rotates, and we with it. And therefore we have the same initial velocity than the Earth to jump and move it horizontally with the same feet. So just falling into the same spot on Earth.
It's like going on an airplane and throw a coin. Despite the high rate at which the aircraft is, our currency is not going to the back of the plane but that we move only vertically, horizontally and to have our own speed.
And the risk of seeming heavy, yet another example. We were all past that, going by train, for a moment circle next to another train at a similar rate and it seems that we are not moving. That's because only appreciate the relative speed between two trains, regardless of how fast the trains go.
So it is possible that the Earth is moving very fast but no spray droplets will allow us to make long trips while we sleep, since both the droplets and ourselves as we move the earth and end up landing in the same spot.
So it could be that the Earth revolved, but how can you check? Well I guess the easiest way to ensure that the Earth rotates is to go to the Museum of Science and stare closer as a simpleton for a good while the pendulum that have hung on the ceiling and oscillating.
is the Foucault pendulum . The pendulum to swing, not change its plane of oscillation, but the objects on the ground does move if the Earth turns. So if we were watching the pendulum for a while, it is pulling the pieces placed on the ground, showing that parts (not the pendulum) are turning. In other words, that the earth revolves.
The Foucault pendulum proves that the Earth rotates about herself.
So, who do we turn to the Earth at the speed that I have said before (about 350 m / s, ie at about 1200 km / h). I thought there once in a while I get dizzy.
Well that's nothing. The other day I was told that the earth revolves around the Sun This implies that the Earth moves (and us with it) at a rate of about 80000 km / h around the sun And pray that no one would say today that the Sun also moves around the center of the galaxy, because I saw enough zeros at school to see that the speed at which I move keeps growing and growing.
