A black star does not require an event horizon, and may or may not be a transitional phase between a collapsing star and a singularity. A black star is created when matter compresses at a rate significantly less than the free fall velocity of a hypothetical particle falling to the center of its star. Quantum processes create vacuum polarization ...
Black star (semiclassical gravity), a theoretical star built using semiclassical gravity as an alternative to a black hole Saturn , referred to as "Black Star" in ancient Judaeic belief Black dwarf , a theoretical stellar remnant formed after cooling of a white dwarf to a sufficient level where heat is no longer emitted
Bliss, originally titled Bucolic Green Hills, is the default wallpaper of Microsoft's Windows XP operating system. It is a photograph of a green rolling hills and daytime sky with cirrus clouds . Charles O'Rear , a former National Geographic photographer, took the photo in January 1998 near the Napa – Sonoma county line, California, after a ...
Gravastar formation may provide an alternative explanation for sudden and intense gamma-ray bursts throughout space. [citation needed] LIGO's observations of gravitational waves from colliding objects have been found either to not be consistent with the gravastar concept, [8] [9] [10] or to be indistinguishable from ordinary black holes. [11] [12]
Ultra HD Blu-ray (4K Ultra HD, UHD-BD, or 4K Blu-ray) [2] [3] is a digital optical disc data storage format that is an enhanced variant of Blu-ray. [4] Ultra HD Blu-ray supports 4K UHD (3840 × 2160 pixel resolution) video at frame rates up to 60 progressive frames per second, [ 4 ] encoded using High-Efficiency Video Coding . [ 4 ]
The list specifically excludes both white dwarfs – former stars that are now seen to be "dead" but radiating residual heat – and black holes – fragmentary remains of exploded stars which have gravitationally collapsed, even though accretion disks surrounding those black holes might generate heat or light exterior to the star's remains ...
Starfield is an action role-playing video game.The player can switch between a first-person and third-person perspective at any time. The game features an open world in the form of an area within the Milky Way galaxy, containing both fictional and non-fictional planetary systems.
A blue supergiant (BSG) is a hot, luminous star, often referred to as an OB supergiant.They are usually considered to be those with luminosity class I and spectral class B9 or earlier, [1] although sometimes A-class supergiants are also deemed blue supergiants.
