The Moving Earth
Even though we cannot sense it, the Earth is constantly in motion. In
fact, the Earth isn't just moving, it's moving really fast! The fact
that we do not feel as if we are moving led people to believe that the
Earth is the stationary center of the universe for centuries.
Eventually, astronomers discovered that the only way to explain
all of the motions they observed in the sky was if the Earth
were really moving. From their observations of the sky, they realized
that there are two components to the Earth's motion; the Earth is orbitting the Sun, and the Earth is spinning like a top.
