The Hoba meteorite is thought to have impacted Earth less than 80,000 years ago. It is inferred [4] that the Earth's atmosphere slowed the object in such a way that it impacted the surface at terminal velocity, thereby remaining intact and causing little excavation (expulsion of earth). Assuming a drag coefficient of about 1.3, the meteor ...

An inhomogeneous cosmology is a physical cosmological theory (an astronomical model of the physical universe's origin and evolution) which, unlike the dominant cosmological concordance model, assumes that inhomogeneities in the distribution of matter across the universe affect local gravitational forces (i.e., at the galactic level) enough to skew our view of the Universe.

The Landless Workers' Movement (Portuguese: Movimento dos Trabalhadores Rurais Sem Terra, MST) is a social movement in Brazil aimed at land reform. Inspired by Marxism, [1] it is the largest such movement [2] in Latin America, with an estimated informal membership of 1.5 million [3] across 23 of Brazil's 26 states. [4]
