3C 273 is a quasar located in the constellation Virgo. It was the first quasar ever to be identified.

It is the optically-brightest quasar in our sky (m ~ 12.9), and one of the closest with a redshift, z, of 0.158. A luminosity distance of DL = 2.4 Giga light years (749 Mpc) may be calculated from z. It is also one of the most luminous quasars known, with an absolute magnitude of -26.7. Its mass has been measured to be 886 ± 187 million solar masses through broad emission-line reverberation mapping.

In general relativity, an event horizon is a boundary in spacetime, most often an area surrounding a black hole, beyond which events cannot affect an outside observer. Light emitted from beyond the horizon can never reach the observer, and any object that approaches the horizon from the observer's side appears to slow down and never quite pass through the horizon, with its image becoming more and more redshifted as time elapses. The traveling object, however, experiences no strange effects and does, in fact, pass through the horizon in a finite amount of proper time.

Horizont udalostí je plocha v priestoročase, ktorá pre daného pozorovateľa vymedzuje oblasť, z ktorej ho nemôže dosiahnuť žiadne elektromagnetické žiarenie (svetlo).

Typickým príkladom horizontu udalostí je hranica čiernej diery -- úniková rýchlosť sa na nej rovná rýchlosti svetla, takže táto oblasť je najskoršia hranica, odkiaľ môže svetlo uniknúť. Inak povedané, pod horizontom všetky časupodobné a svetelné svetočiary zostávajú v čiernej diere (eventuálne smerujú do singularity) a nemôžu ovplyvniť pozorovateľa mimo čiernej diery.

Horizont udalostí pre vonkajšieho pozorovateľa skutočne funguje ako horizont. Vidí objekty padajúce smerom k horizontu sa k nemu približovať, ale (v jeho vlastnom čase) ho nikdy nedosiahnu. Podľa jeho pozorovaní objekty padajú pomalšie a pomalšie smerom k horizontu a počas toho pádu sa červený posuv zväčšuje za všetky hranice až do nekonečna. Taktiež pozorovateľom meraná intenzita žiarenia padajúceho objektu sa rýchlo približuje k nule. V konečnom čase vonkajší pozorovateľ zaznamená posledný fotón z padajúceho objektu, nikdy však neuvidí padajúci objekt prechádzať cez horizont.

Singularity. A point of infinite density and infinitesimal volume, at which space and time become infinitely distorted according to the theory of General Relativity. According to the big bang theory, a gravitational singularity existed at the beginning of the universe. Singularities are also believed to exist at the center of black holes.
