![]() ![]() Their math, laid down in 10 equations, explained how gravity could move around objects via a warped reality, accelerating without ever feeling any mysterious Newtonian forces.Įinstein's inspiration for general relativity struck while he was a patent clerk in Switzerland in 1907. He got help from mathematician Marcel Grossmann, an old friend who shared his notes when a young Einstein skipped class. Confused? The German physicist was, too, and he struggled with the theory for nearly a decade. He described it as a curvature of time and space caused by mass and energy. Newton’s math did a good job at predicting how everything from projectiles to planets moved - but it kept gravity separate from acceleration.Įinstein argued that gravity isn’t a force at all. You may have learned that Newton described gravity as a force, an invisible rubber band that pulls together objects with mass. To link acceleration and gravity in this way, Einstein overthrew one of his own heroes: Isaac Newton. Relativity describes why a clock on a satellite ticks a few dozen microseconds faster than a clock on Earth without accounting for that discrepancy, GPS technologies wouldn’t work. This prediction proved correct when the stars moved during the 1919 solar eclipse. Similarly, he expected a beam of starlight should bend when passing through the sun’s gravity. If the elevator accelerates quickly enough, the beam visibly bends toward the floor.Įinstein showed the same thing happens to a beam inside a stationary elevator within a powerful gravitational field the gravity bends the light. As the light travels sideways, the elevator rises, causing the beam to strike a spot on the wall slightly lower than where it started. Imagine, for example, a horizontal laser inside an elevator that’s accelerating upward. General relativity grew out of Einstein’s theory of special relativity, which describes how the speed of light (in a vacuum) can always be constant.Īccording to relativity, anything that can happen inside of a box picking up speed - i.e., accelerating - also happens in the presence of gravity. This equivalence, “the happiest thought” of Einstein’s life, was his starting point for redefining gravity. His 1915 general theory of relativity built on the notion that gravity and acceleration are not just easily confused, but are one and the same. This spacefarer’s dilemma would have been familiar to Albert Einstein. From inside the vessel, there is - terrifyingly - no way to tell. The ship could be accelerating through space, pressing her into the seat like a race car picking up speed. Her vessel must still be on Earth.īut then a second possibility occurs to her. The only clue is the push of the chair against her body. Sitting alone in a chair, she wonders: “Where in the universe am I?” #WARPED REALITY DEF PROFESSIONAL#If you and your child remain concerned or uncertain about what these symptoms are, contacting a physician or mental health professional is a reasonable next step.An astronaut wakes up in a spaceship, with no memory of how she got there. In some cases, however, these sensations can persist for hours and even days or weeks. Derealization can last for as long as the panic attack lasts, which can range in length from a few minutes to 20 or 30 minutes. ![]() This is a key distinction between derealization and other mental illnesses. ![]() While derealization feels very strange and unsettling, the individual does not lose touch with reality and s/he is able to recognize that their sensations are sensations versus actual events that are happening. Some teens worry these sensations might mean they have schizophrenia or are psychotic. It may help your child feel less “crazy” if they learn that derealization is a common symptom of a panic attack, or extreme stress or anxiety, and that it is not dangerous or indicative of some underlying grave illness. Start by providing some empathy for what must be a scary experience followed by provision of information about what derealization is and is not. If your child or teen comes to you describing what appears to be derealization, it is important you remain calm and attentive to his/her experience. ![]()
