Pulsating stars swell and shrink, affecting their brightness and spectrum. Pulsations are generally split into: radial , where the entire star expands and shrinks as a whole; and non-radial , where one part of the star expands while another part shrinks.
In mathematics, in the field of topology, a topological space is said to have the shrinking property [1] or to be a shrinking space if every open cover admits a shrinking. A shrinking of an open cover is another open cover indexed by the same indexing set, with the property that the closure of each open set in the shrinking lies inside the corresponding original open set.
The assistant, sent as an involuntary scout, shrinks further and further, through the peril of being attacked by a microorganism, down to various worlds, inhabited by various beings who, at their time scales, have seen him approach for years or centuries, including intelligent gaseous beings, cave people, space-faring birdlike beings who flee ...
Representative lifetimes of stars as a function of their masses The change in size with time of a Sun-like star Artist's depiction of the life cycle of a Sun-like star, starting as a main-sequence star at lower left then expanding through the subgiant and giant phases, until its outer envelope is expelled to form a planetary nebula at upper right Chart of stellar evolution
The strength of Earth's magnetic field, as of 2020 (10 −9 T)The South Atlantic Anomaly (SAA) is an area where Earth's inner Van Allen radiation belt comes closest to Earth's surface, dipping down to an altitude of 200 kilometres (120 mi).
An important uniform 5-polytope is the 5-demicube, h{4,3,3,3} has half the vertices of the 5-cube (16), bounded by alternating 5-cell and 16-cell hypercells. The expanded or stericated 5-simplex is the vertex figure of the A 5 lattice, . It and has a doubled symmetry from its symmetric Coxeter diagram.
The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach absolute zero, an event potentially followed by a reformation of the universe starting with another Big Bang.
The shrink ray turns out to be faulty, however, as shrunken items return to normal size after a period of time. A shrink ray is a recurring device shown in Venture Brothers, although it never seems to actually work properly. In Despicable Me, Gru used a shrink ray to shrink the Moon and pocket it. The effects of the shrink ray are only ...
