Black holes are increasingly promoted by [[liberal]] publications, such as the science page of the ''[[New York Times]]'', glossy magazines, and the movies including ''Event Horizon'' (1997), ''The Black Hole'' (TV, 2006), and ''Interstellar'' (2014). Black holes fail the [[falsifiability]] requirement of science, because it is impossible to prove that they do not exist anywhere in the universe.

Black holes have never been directly observed, and there is no direct evidence for their existence. Even believers in black holes should admit that there are far fewer than predicted by theory, and they lose credibility when they fail to address that undisputed truth.  They will cite evidence of observations of radiation from accretion disks, motion of stars near the center of the galaxy, and "gravitational lensing," around places where there are no visible objects.  But at most the evidence for the existence of black holes is circumstantial, with heavy reliance on speculation.

Before 2019 Black holes had never been directly observed, and there was no direct evidence for their existence. In early 2019 astronomers released that first ever image of a super-massive Black Hole located in the galaxy Messier 878 - some 55 million light-years away<ref>https://www.washingtonpost.com/science/2019/04/10/see-black-hole-first-time-images-event-horizon-telescope/</ref>. Believers in black holes should admit that there are far fewer than predicted by theory, and they lose credibility when they fail to address that undisputed truth.  Evidence for their existence relied on the observations of radiation from accretion disks, motion of stars near the center of the galaxy, and "gravitational lensing," around places where there are no visible objects.  Most the evidence for the existence of black holes relied on circumstantial evidence, with heavy reliance on theoretical equations.
    
Because of [[quantum mechanics|quantum-mechanical]] phenomena involving Hawking Radiation, discussed later in the article, black holes must emit radiation and thus are a logical contradiction at the microscopic level.

Black holes are literally invisible by traditional means of observation (that is, emission or reflection of some sort of radiation) and so cannot be directly observed, their nature is determined by other means. The evidence that a black hole provides is its extraordinarily strong gravity, which can be deduced from its effect on the motions of nearby stars.

That said however, as particles near the event horizon their velocity increases and particles are drawn closer and closer together resulting in friction which caused a radioactive accretion disc which can be observed on the electromagnetic spectrum not visible to the eye.<ref>https://www.physicsoftheuniverse.com/topics_blackholes_event.html</ref>
