To know the history of an idiom can be useful and interesting, but is not necessary to be able to use the idiom properly.

However, few know this is because 200 years ago s...

The Seventh-day Adventist Church, and some others, say that the custom of meeting for worship on Sunday originated in paganism, specifically Sol Invictus and Mithraism (in which sun god worship took place on Sunday).

Most early models had the Earth at the centre of the Universe. Some ancient Greeks said that the Universe has infinite space and has existed forever. They said it had a set of celestial spheres which corresponded to the fixed stars, the Sun and various planets. The spheres circled about a round but unmoving Earth.

In the 1900s, even better telescopes led astronomers to say that the Solar System is in a galaxy made of billions of stars, which we call the Milky Way.

Because of this, astronomers call the mysterious energy causing the expansion dark energy. By studying the expansion of the Universe, astronomers have also said most of the matter in the Universe may be in a form which cannot be observed by any scientific equipment we have. This matter has been named dark matter.
