- Light-year (Wikipedia)
A light-year, alternatively spelled light year (ly), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi. As defined by the International Astronomical Union (IAU), a light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). Because it includes the word “year”, the term is sometimes misinterpreted as a unit of time.
- Freedom Caucus (Wikipedia)
The Freedom Caucus, also known as the House Freedom Caucus, is a congressional caucus consisting of Republican members of the United States House of Representatives. It is generally considered to be the most conservative and furthest-right bloc within the chamber. The caucus was formed in January 2015 by a group of conservatives and Tea Party movement members, with the aim of pushing the Republican leadership to the right. Its first chairman, Jim Jordan, described the caucus as a “smaller, more cohesive, more agile and more active” group of conservative representatives. Members of the Freedom Caucus are typically considered a part of the MAGA movement and loyalists to Donald Trump.
