Far Lands or Bust (abbreviated FLoB) is an online video series created by Kurt J. Mac in which he plays the video game Minecraft.The series depicts his journey to the "Far Lands", a distant area of a Minecraft world in which the terrain generation does not function correctly, creating a warped landscape.
This is the farthest distance that any photon can freely stream. Similarly, there is a "neutrino horizon" set for the farthest distance a neutrino can freely stream and a gravitational wave horizon at the farthest distance that gravitational waves can freely stream. The latter is predicted to be a direct probe of the end of cosmic inflation.
It differs from the “light travel distance” since the proper distance takes into account the expansion of the universe, i.e. the space expands as the light travels through it, resulting in numerical values which locate the most distant galaxies beyond the Hubble sphere and therefore with recession velocities greater than the speed of light c.
Uses radio counterpart of GW170817, combined with earlier gravitational wave (GW) and electromagnetic (EM) data. 2019-03-28 68.0 +4.2 −4.1: Fermi-LAT [121] Gamma ray attenuation due to extragalactic light. Independent of the cosmic distance ladder and the cosmic microwave background. 2019-03-18 74.03 ± 1.42: Hubble Space Telescope [71]
d is the total horizontal distance travelled by the projectile. v is the velocity at which the projectile is launched; g is the gravitational acceleration—usually taken to be 9.81 m/s 2 (32 f/s 2) near the Earth's surface; θ is the angle at which the projectile is launched; y 0 is the initial height of the projectile
The cosmic distance ladder (also known as the extragalactic distance scale) is the succession of methods by which astronomers determine the distances to celestial objects. A direct distance measurement of an astronomical object is possible only for those objects that are "close enough" (within about a thousand parsecs ) to Earth.
It overtook Pioneer 11 in 1981, [13] and then Pioneer 10—becoming the probe farthest from the Sun—on February 17, 1998. [14] Voyager 2 is moving faster than all other probes launched before it; it overtook Pioneer 11 in the late 1980s and then Pioneer 10 — becoming the second-farthest spacecraft from the Sun — on July 18, 2023.

[18] [19] The research team used Hubble's Wide Field Camera 3 to measure the distance to GN-z11 spectroscopically, measuring the redshift caused by the expansion of the universe. [20] The findings, which were announced in March 2016, revealed the galaxy to be farther away than originally thought, at the distance limit of what the Hubble ...
