The current meeting place can be found on thLASFS website LASFS is the oldest continuously operating science fiction club in the world, helped considerably in that record by being one of the few to have owned a clubhouse. The organization continues to hold regular weekly meetings on Thursdays. The club maintains a private lending library of books, videos, and other genre-related materials, for use by members. Members of the club have run the World Science Fiction Convention several times, initiated the regional science-fiction convention Westercon, and hosts a yearly science fiction convention called Loscon.

Solar System
The Solar SystemCapitalization of the name varies. The International Astronomical Union, the authoritative body regarding astronomical nomenclature, specifies capitalizing the names of all individual astronomical objects but uses mixed "Solar System" and "solar system" structures in theinaming guidelines document. The name is commonly rendered in lower case ('solar system'), as, for example, in the ''Oxford English Dictionary'' an''Merriam-Webster's 11th Collegiate Dictionary''. is the gravity, gravitationally bound system of the Sun and the objects that orbit it. It Formation and evolution of the Solar System, formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The solar mass, vast majority (99.86%) of the system's mass is in the Sun, with most of the Jupiter mass, remaining mass contained in the planet Jupiter. The four inner Solar System, inner system planets—Mercury (planet), Mercury, Venus, Earth and Mars—are terrest ...

Alderson Disk
An Alderson disk (named after Dan Alderson, its originator) is a hypothetical artificial astronomical megastructure, like Larry Niven's Ringworld and the Dyson sphere. The disk is a giant platter with a thickness of several thousand miles. The Sun rests in the hole at the center of the disk. The outer perimeter of an Alderson disk would be roughly equivalent to the orbit of Mars or Jupiter. According to the proposal, a sufficiently large disk would have a larger mass than its Sun. The hole would be surrounded by a thousand-mile-high wall to prevent the atmosphere from drifting into the Sun. The outer rim would take care of itself. The mechanical stresses within the disc would be far beyond what any known material can stand, thus relegating such a structure to the realm of exploratory engineering until materials and construction science become sufficiently advanced. Building a megastructure of this magnitude would require an amount of material that far surpasses the amount of ...

Alderson Drive
CoDominium is a series of future history novels written by American writer Jerry Pournelle, along with several co-authors, primarily Larry Niven. Series Setting Formation of the CoDominium The point of departure of Pournelle's history is the establishment of the ''CoDominium'' (CD), a political alliance and union between the United States of America and a revitalized Soviet Union. This union, achieved in the name of planetary stability, reigns over the Earth for over a hundred years. In that time, it achieves peace of a sort, as well as interstellar colonization, but at the price of a complete halt in both scientific and political evolution. The CoDominium (CD) is a supranational alliance of the United States of America and the Union of Soviet Socialist Republics. This alliance eventually becomes a ''de facto'' planetary government, and later, an interstellar empire. Despite this, no other nations on Earth are given representation or membership. Other major powers become ...
