Physicists Have Come up With a New Theory About Earth and Black Holes Which Will Blow Your Mind
Black holes remain a mystery in the universe even after decades of research by scientists into these remnants of celestial objects that have collapsed, as per IFL. Most people know it as a part of the cosmos with a gravitational pull so strong that even light cannot escape. One chilling study suggests that our planet Earth might be on the edge of a black hole itself. French astrophysicist Jean-Pierre Luminet's 2016 study mentioned that "a black hole prevents any particle or form of radiation from escaping from its cosmic prison." "For an external observer, when a material body crosses an event horizon all knowledge of its material properties is lost. Only the new values of M [mass], J [angular momentum], and Q [electric charge] remain. As a result, a black hole swallows an enormous amount of information," he added.
The last stage of a black upon reaching its equilibrium only depends on parameters like its mass, angular momentum and electric charge. So studying them in terms of thermodynamics has been difficult. "Hawking then pointed to a paradox. If a black hole can evaporate, a portion of the information it contains is lost forever," Luminet continued. "The information contained in thermal radiation emitted by a black hole is degraded; it does not recapitulate information about matter previously swallowed by the black hole."
He mentioned how according to the Schrödinger equation, "physical systems that change over time cannot create or destroy information, a property known as unitarity and hence this is known as the black hole paradox." "From the point of view of information, each bit in the form of a 0 or a 1 corresponds to four Planck areas, which allows one to find the Bekenstein–Hawking formula for entropy," Luminet continues. "For an external observer, information about the entropy of the black hole, once borne by the three-dimensional structure of the objects that have crossed the event horizon, seems lost. But in this view, the information is encoded on the two-dimensional surface of a black hole, like a hologram."
Other theories suggest that our universe itself could be a black hole and that gravity could arise as an emergent force from entanglement entropy at the boundary of the black hole where Earth is supposedly situated. On the other hand, some cosmologists believe that our universe rests inside another universe's black hole. According to a study published in Popular Mechanics, "it is suggested that the massive instabilities created from the Big Bang might grow, leading to the formation of branched-off 'bubbles' that are completely isolated from the universe hosting the original black hole."
"These bubbles would have their own Big Bangs, their own expansions, their own everything totally separate from anything else. They would be their own universes, split off from the parent universe that spawned them." In the past decade, scientists have detected the signals of the collision of black holes and taken images of the light from gas swirling around them, all of which has helped us learn many things about the universe.
