There is no credible evidence or documentation to suggest that Albert Einstein ever advised or suggested that Earth could go into a black hole and emerge unscathed. While Einstein made significant contributions to the field of theoretical physics, including his theory of general relativity, which describes the behavior of gravity and the nature of black holes, he did not propose such a scenario.
Black holes are incredibly dense objects with a gravitational pull so strong that nothing, including light, can escape their event horizon. The gravitational forces near a black hole are so intense that they would spaghettify any object or planet that ventured too close. Based on our current understanding of physics, it is highly unlikely that any object, including Earth, could survive entering a black hole.
It's important to be cautious of information presented in pseudo-documentaries, as they often mix fictional elements with real scientific concepts. When it comes to scientific claims, it's best to rely on reputable scientific sources and peer-reviewed research.
