  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?

  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

The origin of the moon

submitted by Ornthoron

1 decade 5 years 5 months 2 weeks ago

The theory of the moon's formation that has proven most fruitful is the so-called Giant Impact Theory. In this theory, an early protoplanet dubbed Theia shared Earth's orbit at the beginning of the solar system. It then collided with the Earth to make the moon. This video shows a computer simulation of this event, made at the University of Colorado.
