Well, honey, if the compass was never invented, we'd all be lost like a bunch of chickens with their heads cut off. Sailors would be sailing in circles, explorers would be wandering aimlessly, and Google Maps would be useless. So, thank your lucky stars for that little magnetic needle pointing us in the right direction.
We cannot sea the space
People arleady knew how to navigate using stars (for instance before the compass was invented). And anyone seriously working with magnets would've stumbled across one that could be used as a compass eventually.
It will keep on flying and never come to ground
The world zombie appocalaps would happen and it will be the end.
No, a traditional compass would not work at the center of the Earth because it relies on the Earth's magnetic field which would be disrupted by the extreme heat and pressure at that depth. Additionally, at the center of the Earth, gravity would be pulling equally in all directions which would affect the accuracy of the compass needle.
the world would exploder
You would walk.
We cannot sea the space
We can't talk to anyone in different places.
Then Pepsi would take over Coca Cola
the arrow in the compass would point to the magnet
it would spin around and around.
There would be a lot more people dying of diabetes related diseases.
Yahoo would suck a little less. (We would probably use other search engines.)
The compass effected exploration because without it, exploration would not have been possible to the early peoples. The compass was invented in China, and some of the earliest explorers were in Egypt. :)
The compass needle would be affected by the magnetic field from the nearby magnet. The needle would align itself with the magnetic field of the magnet, causing the compass to point in a direction different from true north.
Some invented tratitions would be things like: The Edinburgh Military Tattoo The World Pipe Band Championship Basically things that happen often but were never done by your ansestors. In short they were invented.
