The creepypasta showed an image exemplifying a liminal space—a hallway with yellow carpets and wallpaper—with a caption purporting that by "noclipping out of bounds in real life", one may enter the Backrooms, an empty wasteland of corridors with nothing but "the stink of old moist carpet, the madness of mono-yellow, the endless background ...
The discovery (by chance in 1965) of the cosmic background radiation suggests that the early universe was dominated by a radiation field, a field of extremely high temperature and pressure. [ 1 ] The Sunyaev–Zel'dovich effect shows the phenomena of radiant cosmic background radiation interacting with " electron " clouds distorting the ...
Webb's First Deep Field is the first full false-color image from the JWST, [12] and the highest-resolution infrared view of the universe yet captured. [11] The image reveals thousands of galaxies in a tiny sliver of the universe, with Webb's sharp near-infrared view bringing out faint structures in extremely distant galaxies, offering the most ...
In the baryonic material of the Universe there are two sources of large amounts of energy: nuclear fusion and gravitation. Nuclear fusion takes place inside the stars, and we can really see this light redshifted: this is the main source of the cosmic ultraviolet- and visual background .
Most of the radiation energy in the universe is in the cosmic microwave background, [58] making up a fraction of roughly 6 × 10 −5 of the total density of the universe. [ 59 ] Two of the greatest successes of the Big Bang theory are its prediction of the almost perfect black body spectrum and its detailed prediction of the anisotropies in ...
Up until the discovery of JADES-GS-z13-0 in 2022 by the James Webb Space Telescope, GN-z11 was the oldest and most distant known galaxy yet identified in the observable universe, [7] having a spectroscopic redshift of z = 10.957, which corresponds to a proper distance of approximately 32 billion light-years (9.8 billion parsecs).
"Late universe" measurements using calibrated distance ladder techniques have converged on a value of approximately 73 (km/s)/Mpc. Since 2000, "early universe" techniques based on measurements of the cosmic microwave background have become available, and these agree on a value near 67.7 (km/s)/Mpc. [64] (This accounts for the change in the ...
HD 140283 (also known as the Methuselah star) is a metal-poor subgiant star about 200 light years away from the Earth in the constellation Libra, near the boundary with Ophiuchus in the Milky Way Galaxy. Its apparent magnitude is 7.205, so it can be seen with binoculars. It is one of the oldest stars known.
